In order to run the iQpump drive and motor, the iQpump drive must receive a Run command and a Auto Setpoint command. Parameter
b1-01 specifies from where the Auto Setpoint is received when in the “Auto” mode. Switching into the “Auto” mode can be done by
pressing the AUTO button on the digital operator while the iQpump drive is stopped.
Important: If a Run command is input to the iQpump drive but no corresponding Auto Setpoint is input, the Run indicator on the digital
operator will turn on and the STOP indicator on the digital operator will blink.
To configure the iQpump drive to follow the “Hand Reference” set by the digital operator: Use the “Hand” mode by pressing the
hand key and set P5-01 = “1: Hand Reference (P5-02)”. The hand reference can then be entered into the P5-02 parameter.
The iQpump drive offers the ability to provide four types of “Auto Setpoint” reference sources. These Auto Setpoint reference sources are
determined by the setting of b1-01 and the drive set to “Auto” mode by pressing the Auto key on the digital operation.
Note: Prior to programming, it is recommended to first select the system units (P1-02) and the feedback device, Scaling
(P1-03). P1-03 will automatically scale the iQpump Setpoint.
Example:
P1-02 = 1: psi
P1-03 = 200, feedback range = 200 psi.
To configure the iQpump drive to follow an “Auto Setpoint” set by the digital operator: Set b1-01 = “0: Operator” (factory default),
The Auto Setpoint can then be entered into the U1-01 monitor parameter in the “-DRIVE-” menu.

The iQpump drive comes factory programmed for Start and Stop from the Keypad.
The iQpump drive can be programmed to receiver a Run command from four different inputs: digital operator, terminals, serial
communications, or an option PCB.
If the Run command input is determined by the digital operator: Set b1-02 = “0: Operator,” and the HAND and OFF keys will be
used to provide the Run command to the iQpump drive.
b1-02 = 1, Terminals
If the Run command input is determined by the external terminals: Set b1-02 = “1: Terminals” and initiate an external Run
command by a contact closure between terminals S1 and SN. Refer to Figure 8. for the connection diagram of the external Run
command.
Note: To use the external terminals requires the iQpump drive to be set to “Auto” mode by pressing the Auto key.
Select between 2-wire and 3-wire control operation by doing the following:
2-Wire Control The factory default setting is for 2-wire operation. In the 2-wire configuration a closure between S1 and SN will be
interpreted as a Forward Run command by the drive.

Figure 6. 2-Wire Control
3-Wire Control When any of the multi-function digital input parameters, H1-01 through H1-05, is set to 0, terminals S1 and S2 become
Run and Stop, respectively. The multi-function digital input that was set to 0 will function as a Forward / Reverse input for the iQpump
drive. When the Forward / Reverse input is open the iQpump drive will run in the Forward direction and when the input is closed, the
iQpump drive will run in the Reverse direction.
In 3-wire operation a momentary closure (> 50mS) of S1 will cause the iQpump drive to run provided that S2 is held closed. The iQpump
drive will stop anytime the S2-SN connection is broken. If the 3-wire configuration is implemented via a 3-wire Initialization (A1-03 =
“3330: 3-Wire Initial”), then terminal S3 becomes the Forward / Reverse input.
Note: Reverse operation is disabled in the iQpump drive; however, in 3-wire control, one of the multi-function digital inputs
needs to be programmed to 0. Otherwise, the 3-wire control will not work.

b1-02 = 5, Timed Run
If the Run command input is determined by a Timed Run: “b1-02 = 5: Timed Run,” when this feature is enabled, the drive will run at
the HAND frequency reference for the time specified in parameter P4-18. Timed Run cannot be enabled when in multiplex mode
(P1-01 > 0).

•
Only enabled when all three Run / Stop Control parameters are set to a value greater than zero (P4-18 > 0, P4-19 > 0, and P4-20 > 0).
Available only when in HAND or LOCAL mode.
PI control is disabled.
Will always start off running when a run command is given.
A stop command, power loss or fault will reset all timers and counters associated with the Run / Stop Control.
A stop command will result in a stopping method set by parameter b1-03.
When the “Run” portion of the timer expires, the drive stop using the stopping method set by parameter b1-03.
When stopped due to the “Run” timer expired, the standard “sleep” message will be displayed on the operator.
When stopped because the final cycle count has been exceeded, the digital operator will display “Run / Stop Finished”. The display
will be cleared when a stop command is given or power is lost.
• If a fault (not auto-restart) occurs during Run / Stop Control, all timers and counters are reset.
• If an auto-restart is in process, under most circumstances the Run / Stop Control will continue to operate. However, if the stop timer
expires prior to the auto-restart expiring, the drive will wait until the auto-restart time expires before resuming normal Run / Stop
Control.
When this feature is enabled and the drive is given a run command, the drive will run for the time specified in parameter P4-18, then stop
for the time specified in parameter P4-19. It will do this the number of times programmed in parameter P4-20. (Refer to parameters P418, P4-19 and P4-20.) The display will show one of two messages if the drive is stopped due to this feature. Run-Stop control cannot be
enabled when a multiplex mode (P1-01 > 0).
Timed Run:
If parameter b1-02 is set to 5 “Timed Run”, the timed run feature will be enabled. When “Timed Run” is enabled, Terminal S1 will be a
normally open “start” input and Terminal S2 will be a normally closed “stop” input. The drive can be started by either causing a rising
edge (open to close) on the S1 digital input when S2 is closed, or both S1 and S2 are closed when power is applied to the drive. The drive
will then start running at the HAND frequency reference P5-02 and run for the time specified in parameter P4-18. If the drive needs to be
stopped before the P4-18 timer expires, the circuit connected to Terminal S2 can be opened, or the Stop or Off keys on the digital operator
can stop the drive. The drive can be re-started by simply causing another rising edge on Terminal S1. There will be no modified display or
messages when the drive is stopped due to the Timed Run feature. If the drive is switched into HAND or LOCAL mode, the timed run
feature will be disabled.

0: Ramp to stop: When the Run command is removed, the iQpump drive will decelerate the motor to 0 rpm. The rate of deceleration is
determined by the active deceleration time. The factory default Decel Time is in parameter C1-02.
When the output frequency has dropped below the DC Injection Start Frequency in b2-01 (Default = 0.5 Hz) DC current will be injected
in the motor at a level determined by b2-02 (50% Default). The DC Injection condition will occur for the time specified by b2-04 (0.0
Default), to establish the end point of the ramp. DC injection can be used to insure the motor is at zero rpm prior to the iQpump drive
shutting off.

b2 DC Braking
The DC Braking Group contains parameters associated with the DC injection braking feature. Parameters involving the starting
frequency, current level, braking time, and motor pre heat current level are located here.
в—† b2-01 DC Injection Braking Start Frequency
Setting Range:
0.0 ~ 10.0 Hz
Factory Default: 0.5 Hz
Parameter b2-01 sets the output frequency where the iQpump drive begins DC Injection during Ramp to stop in order to lock the rotor
of the motor and established the end point of the ramp. If b2-01 < E1-09 (Minimum Frequency), then DC Injection begins at E1-09.
Parameter b2-01 also determines the output frequency that the iQpump drive must be at or below before a Zero Speed condition is
considered true. This affects any digital output configured as a Zero Speed signal (H2-0x = “1: Zero Speed”).

The level of DC Injection Braking Current affects the strength of the magnetic field attempting to lock the motor shaft. Increasing the
level of current will increase the amount of heat generated by the motor windings and should only be increased to the level necessary to
hold the motor shaft. DC Injection current is set in percentage of the iQpump drive rated output current. iQpump drive rated output
current is stated on the iQpump drive nameplate.

The iQpump drive can be programmed to automatically DC Inject for a predetermined amount of time prior to accelerating to speed (b203) and / or at the end of a Ramp to stop (b2-04). Parameter b2-03 can be used to stop a rotating motor prior to attempting acceleration
(i.e. a wind milling fan). If DC Injection braking at start or Speed Search is not enabled, attempting to drive a spinning motor may cause
nuisance tripping.
Parameter b2-04 can be used to resist any residual motion of the load after the deceleration has finished.

в—† b2-09 Motor Pre-Heat Current
Setting Range:
0 ~ 100%
Factory Default: 0%
A DC current can be circulated within the motor windings while the motor is stopped. The current will produce heat within the motor and
prevent condensation. Parameter b2-09 determines the percentage of the iQpump drive rated output current that will be used for the motor
pre-heat function. This function can be useful in applications where the motor sits for extended periods of time in humid conditions.
Motor pre-heating can only be initiated by closing a digital input programmed as a Motor Pre-heat Input (H1-0x = 60). Check with the
motor manufacturer to determine the maximum acceptable current level the motor can withstand when stopped. Be sure not to exceed the
motor manufacturers recommended level.

YASKAWA TM.iQp.07 iQpump Controller Programming Manual
b3 Speed Search
The Speed Search function allows the iQpump drive to determine the speed of a motor shaft that is being driven by rotational inertia.
Speed Search will allow the iQpump drive to determine the speed of the already rotating motor and begin to ramp the motor to a set speed
without first having to bring it to a complete stop. When a momentary loss of supply power is experienced, the iQpump drive output is
turned off. This results in a coasting motor. When power returns, the iQpump drive can determine the speed of the coasting motor and
start without requiring it to be brought to minimum speed. Speed Search can be programmed to always be active by setting b3-01 or it can
be commanded by remote contact closure by setting a digital input.
There are two forms of Speed Search in the drive, the speed estimation method and the current detection method.
Important: When setting the iQpump drive for remote Speed Search input, via a contact closure, the method of Speed Search is
determined by the setting of b3-01. If b3-01 = “0: SpdsrchF Disable” then the remote input will initiate speed estimation method, and if
b3-01 = “2: SpdsrchI Disable,” then the remote input will start the current detection method.
Parameters L2-03 and L2-04 also affect the current detection method of Speed Search operation.

Speed Estimation: Method (b3-01 = 0 or 1) The speed estimation method will calculate the speed using measurements of residual
motor fields. The speed estimation version is bi-directional and will determine both the motor speed and direction. To enable speed
estimation Speed Search at start, set b3-01 = “1: SpdsrchF Enable”.
Important: If the speed estimation method of Speed Search is to be used, then Auto-tuning must be performed prior to using Speed
Search. If the length of cable between the iQpump drive and motor is ever changed after Auto-tuning then Auto-tuning should be
performed again
Important: The speed estimation mode cannot be used when there are multiple motors operated by one iQpump drive or the motor is two
or more frames smaller than the standard size motor per the iQpump drive capacity.

Current Detection Method (b3-01 = 2 or 3): The current detection method starts searching from a predetermined frequency while
monitoring the iQpump drive output current to determine when the rotor speed and the iQpump drive output speed (frequency) match.
The current detection version is not bi-directional. To enable current detection Speed Search at start set b3-01 = “3: SpdscrhI enable” and
program any digital input equal to Speed Search 1 (H1-0x = 61) or Speed Search 2 (H1-0x = 62). Speed Search 1 will start searching from
the max. frequency (E1-04) and ramp down to meet the rotor speed. Speed Search 2 will start searching from the set frequency and ramp
down to meet the rotor speed.
Important: If a UV1 fault occurs when current detection Speed Search is attempted, increase the setting of L2-04.
Important: If an OC fault occurs when Speed Search is attempted after power loss recovery, increase the setting of L2-03.

When using the current detection method of Speed Search, parameter b3-02 sets the current level that will determine when the search is
complete and the rotor and output speeds match. When the output frequency is higher than the actual rotor speed, the slip causes the
current to be high. As the output frequency is lowered, the closer it comes to the rotor speed, the lower the current draw will be. When the
output current drops below the level as set in b3-02 (100% = iQpump drive Rated Current) the output frequency stops decreasing and
normal operation resumes.

Parameter b3-03 sets the deceleration ramp used by the current detection method of Speed Search when searching for the motor’s rotor
speed. Even if Speed Search 2 is selected, for Speed Search at start, the time entered into b3-03 will be the time to decelerate from

The analog feedback to the iQpump drive for the PI control is via the A2 terminal. The iQpump drive must be programmed (H3-09 = “B:
PI Feedback”) to use terminal A2 as feedback for the PI functionality of the drive.
The PI Setpoint can be configured to come from one of many different inputs or parameters. Table 6 on page 32 describes the options for
originating the PI Setpoint.

In some situations there are two feedback inputs. The drive can be programmed to maintain a set differential between two analog signals.
If input A2 is configured as a “PI Differential Mode” (H3-09 = “16: PI Differential”), then the iQpump drive will maintain a set
difference between the measurements read on inputs A1 and A2. This differential setpoint is programmed by parameter (b5-07).

The iQpump drive can be used as a stand-alone PI controller. If PI functionality is selected by parameter b5-01, the iQpump drive will
adjust its output to cause the feedback from a transmitter to match the PI Setpoint (b5-19). The setting of b5-01 will determine whether PI
functionality is disabled (b5-01 = “0: Disabled”), enabled (b5-01 = “1: Enabled”), enabled - 2 zone (dual zone PI enabled) (b5-01 = 2).
b5-01 = 0, Disabled

•
•
When the drive is in auto mode, the digital operator display will change as noted in Table 6 on page 32.
Terminal A1 becomes a PI feedback, assigned to Zone 1.
Standard PI feedback is assigned to Zone 2 (requires H3-09 = B).
If feedback on Terminal A1 within the P4-17 value of the feedback on Terminal A2, the drive will use the d1-04 parameter as the
setpoint. It will use either Terminal A1 or Terminal A2 as feedback depending on which one is higher. The feedback signal(s) need to
be different for more than 5 seconds before any switching between the two will occur.
• If the feedback on Terminal A1 is more than the feedback on Terminal A2 plus the P4-17 value for more than 5 seconds, the drive will
then operate off of the Zone 1 setpoint (d1-02) and the Zone 1 feedback (Terminal A1).
• If the feedback on Terminal A2 is more than the feedback on Terminal A1 plus the P4-17 value for more than 5 seconds, the drive will
then operate off of the Zone 2 setpoint (d1-03) and the Zone 2 feedback (Terminal A2).
From the main “Auto Mode” display see Table 6 on page 32, if the <Data / Enter> key is pressed, the currently active setpoint will be
editable.
Note: To convert Terminal A1 to a 4 - 20 mA signal, connect a 250 Ohm precision resistor (1/4 Watt or greater) between A1
and AC. Then program H3-02 = 231.3% and H3-03 = 25.0%.

в—† b5-02 Proportional Gain Setting
Setting Range:
0.00 ~ 25.00
Factory Default: 2.00
The proportional gain will apply a straight multiplier to the calculated difference (error) between the PI Setpoint and the measured
transmitter feedback at terminal A2. A large value will tend to reduce the error but may cause instability (oscillations) if too high. A small
value may allow to much offset between the setpoint and feedback (See Figure 29. on following page).

в—† b5-03 Integral Time Setting
Setting Range:
0.0 ~ 360.0 s
Factory Default: 3.0 s
The Integral factor of PI functionality is a time-based gain that can be used to eliminate the error (difference between the setpoint and
feedback at steady state). The smaller the Integral Time set into b5-03, the more aggressive the Integral factor will be. To turn off the
Integral Time, set b5-03 = 0.00.

в—† b5-04 Integral Limit Setting
Setting Range:
0.0 ~ 100.0%
Factory Default: 100.0%
On some applications, especially those with rapidly varying loads, the output of the PI function may have large oscillations. To suppress
these oscillations, a limit can be applied to the integral factor by programming b5-04.
в—† b5-06 PI Output Limit
Setting Range:
0.0 ~ 100.0%
Factory Default: 100.0%
Places a cap on the output of the PI function. Limiting the PI function may help to prevent large overshoots in the drive’s response to error
(the difference between the setpoint and the feedback).
в—† b5-07 PI Offset Adjustment
Setting Range:
-100.0% ~ +100.0%
Factory Default: 0.0%
The PI Offset Adjustment parameter has two different uses. Parameter b5-07 serves different functions depending on whether it is used
on a standard PI loop or a Differential PI loop.
Parameter b5-07 causes an offset to be applied to the output of the PI function in a non-Differential PI loop. Every time the PI output is
updated, the offset (b5-07) is summed with the PI output. This can be used to artificially kick-start a slow starting PI loop.
If the iQpump drive is configured for Differential PI Regulation (H3-09 = “16: PI differential”), then this parameter is the target setpoint
for the differential to be maintained between the signal measured on analog input A1 and the signal measured on analog input A2.

в—† b5-08 PI Primary Delay Time Constant
Setting Range:
0.00 ~ 10.00 s

Setting
Description

Normal Output (direct acting) (factory default)
1
Reverse Output (reverse acting)
Normally, the output of the PI function causes an increase in motor speed whenever the measured feedback is below the setpoint. This is
referred to as direct acting response. However, if b5-09 = “1: Reverse Output,” the output of the PI function causes the motor to slow
down when the feedback is below the setpoint. This is referred to as reverse acting response.
в—† b5-10 PI Output Gain Setting
Setting Range:
0.0 ~ 25.0
Factory Default: 1.0
Applies a multiplier to the output of the PI function. Using the gain can be helpful when the PI function is used to trim the Speed
Command. Increasing b5-10 causes the PI function to have a greater regulating affect on the speed command.

Fault (factory default)
Loss of feedback can cause problems to a PI application. The iQpump drive can be programmed to turn on a digital output whenever a
loss of feedback occurs. Feedback Loss Detection (FBL) is turned on by b5-12. When b5-12 = “1: Alarm,” the iQpump drive
acknowledges the loss of feedback without stopping or turning on the fault output (MA-MB). If b5-12 = “2: Fault,” the iQpump drive
coasts to a stop and turns on the fault output if the feedback is determined to be lost.
The Feedback Loss Detection can be disabled during the following conditions:
• Pre-charge Level (P4-01) is set to 0.
• Thrust Bearing acceleration or deceleration.
Note: A Feedback Loss Detection (FBL) will occur when the Thrust Bearing function is enabled and a run command given, P1
Feedback Loss Detection Time (b5-14) is set to 0, and P1 Feedback is below Feedback Loss Detection Level (b5-13).
Function Description <0034>
This parameter also allows feedback loss detection to also function as a wire break detection when the signal type is 4 ~ 20mA. The Wirebreak Feedback Loss Detection will still be active when b5-13 = 0%.
Wire break will be detected on Terminal A2 when:
•
•
•

Note: Wire break detection on Terminal A2 is unaffected by the gain / bias parameters H3-10 and H3-11.

Note: Wire break detection on Terminal A1 occurs after the gain / bias parameters (h3-02 and H3-03) are applied.
Feedback Loss (wire-break):
The drive will then react depending on how parameter b5-12 is programmed. However, if b5-12 is set to “fault” (b5-12 = 2), the drive will
only fault when running in “Auto” mode. A warning will only be displayed if the drive is not running, or is running in “Hand” mode.
Feedback Loss (standard):

в—† b5-17 PI Accel / Decel Time
Setting Range:
0.0 ~ 25.5 s
Factory Default: 0.0 s
This is a soft start function that is applied to the PI Setpoint analog input. Instead of having nearly instantaneous changes in signal levels,
there is a programmed ramp applied to level changes. When changing setpoints the error can be limited by gradually ramping the setpoint
through the use of parameter b5-17.
в—† b5-32 Integrator Ramp Limit <0034>
The Integrator Ramp Limit provides a way to tune the PI loop so that it is less reactive to sudden spikes and dips in the feedback signal.
Sometimes in a pressure regulated system with a very long piping system, pressure waves can develop which without this feature, can
cause instability in the PI controller.
This feature only applies to the drive’s standard PI Loop. It will not be applied to the PI Loop associated with water level control (Well
Draw Down Control).
Function Description <0034>
Integrator Ramp Limit.
When the Integrator Ramp Limit is enabled, the PI Integrator is limited to +/- the b5-32 value of the soft starter output (output frequency
without slip compensation). A b5-32 setting of zero disables this feature and the integrator is allowed to operate normally.

b8 Energy Savings
The energy savings function improves overall system operating efficiency by operating the motor at its highest efficiency. This is
accomplished by continuously monitoring the motor load and adjusting the motor terminal voltage so that the motor always operates near
its rated slip frequency. A motor is most efficient when operating near rated slip conditions.
в—† b8-01 Energy Savings Selection
Setting
Description
0
Disabled (factory default)
1
Enabled
When the Energy Savings function is enabled (b8-01 = “1: Enabled”), the iQpump drive reduces the output voltage to the motor below
the voltage value specified by the programmed V/f pattern whenever the motor load is light. Since torque is reduced during this voltage
reduction, the voltage has to return to normal levels when the load returns. The energy savings is realized through improved motor
efficiency. The reduced output voltage causes increased rotor slipping even with a light load. A motor is most efficient when operating
fully loaded (i.e. operating at rated slip).
в—† b8-04 Energy Saving Coefficient Value
Setting Range:
0.0 ~ 655.0
Factory Default: Model Dependent
Parameter b8-04 is used in maximizing motor efficiency. The factory setting will be iQpump drive capacity dependant but can be adjusted
in small amounts while viewing the kW monitor (U1-08) and running the iQpump drive to minimize the output kW. A larger value
typically results in less voltage to the motor and less energy consumption. Too large a value will cause the motor to stall.
в—† b8-05 Power Detection Filter Time
Setting Range:
0 ~ 2000 ms
Factory Default: 20 ms
The Energy Saving function will search out the lowest output voltage in order to achieve minimum output power usage. Parameter b8-05
determines how often the output power (kW) is measured and the output voltage is adjusted.
в—† b8-06 Search Operation Voltage Limit
Setting Range:
0 ~ 100%
Factory Default: 0%
Once Energy Savings is enabled and the optimal energy saving coefficient value has been set, the programmer can have the iQpump drive
further search out the proper voltage to achieve the lowest output power by making minute changes to the output voltage and measuring
the output power every b8-05 ms. Parameter b8-06 sets limits to the range over which the voltage will be adjusted in order to minimize
the power output. Settings too large a value may allow the motor to stall if the load is applied abruptly.
If b8-06 = 0, then the optimum voltage search operation is disabled (but not Energy Savings itself).

C1-01 (Acceleration Time 1) sets the time to accelerate from zero to maximum speed (E1-04). C1-02 (Deceleration Time 1) sets the time
to decelerate from maximum speed to zero. C1-01 and C1-02 are the factory default active accel / decel “pair”. Another accel / decel pair
(C1-03 and C1-04) exists that can be activated by a multi-function digital input (H1-0x = 7), or specified by a switch over frequency as
programmed in parameter C1-11.
C1-05 (Acceleration Time 3) and C1-06 (Deceleration Time 3) are used during the multiple pumping operation. Refer to P3-12 for more
details.
Acceleration Time: This is the time it takes to accelerate from 0 Hz to Maximum Output Frequency defined by parameter E1-04.
Deceleration Time: This is the time it takes to decelerate from Maximum Output Frequency defined by parameter E1-04 to 0 Hz.
Example: C1-01 Acceleration Time 1 programmed for 30 seconds, E1-04 Maximum Output Frequency set to 60 Hz. It will take the
iQpump Controller 20 seconds to accelerate from 0 to 40 Hz (40 Hz Г· 60 Hz x 30 s = 20 s).
Example: C1-02 Deceleration Time 1 programmed for 50 seconds, E1-04 Maximum Output Frequency set to 60 Hz. It will take the
iQpump Controller 10 seconds to decelerate from 60 to 30 Hz (30 Hz Г· 60 Hz x 50 s = 25 s).
• Thrust Bearing Operation uses a separate acceleration time defined by parameter P4-04. Once Thrust frequency is reached, the iQpump
drive returns to its normal acceleration time set by C1-01.
• Pre-charge mode uses C1-01 as its acceleration time.
• Hand Mode Operation uses C1-01 and C1-02 for acceleration and deceleration time.
• Auto Mode can use acceleration time C1-05 and deceleration time C1-06, depending on parameter P3-12 setting (see section. P3-12
Delta Setpoint Feedback Acc / Dec Changeover on page 183.)
в—† C1-09 Fast Stop Time
Setting Range:
0.0 ~ 6000.0 s
Factory Default: 10.0 s
A special deceleration parameter is available for use with emergency or fault operations. Parameter C1-09 will set a special deceleration
that can be operated by closing a digital input configured as H1-0x = 15 or H1-0x = 17. A digital input configured as H1-0x = 15 will look
for a switch closure before initiating the Fast Stop operation. A digital input configured as H1-0x = 17 will look for the switch opening
before initiating the Fast Stop operation.
Unlike a standard deceleration time, once the Fast Stop operation is initiated even momentarily, the iQpump drive cannot be re-operated
until the deceleration is complete, the Fast Stop input is cleared, and the Run command is cycled.
The C1-05 (Acceleration Time 3) and C1-06 (Deceleration Time 3) are used during the multiplex pumping operation. Refer to P3-12 for
more details.

input is required. If parameter C1-11 is set to a frequency other than zero, the iQpump drive will use Acceleration 1 and Deceleration 1
whenever the output frequency is equal to or above the value of C1-11 and use Acceleration 2 and Deceleration 2 whenever the output
frequency is below the value of C1-11.
A multi-function input programmed as “Multi-Acc / Dec 1” will have priority over C1-11. For example, if the output frequency is greater
than the value of C1-11 but a digital input configured as “Multi-Acc / Dec 1” is closed then Acceleration 2 and Deceleration2 are active.

C4 Torque Comp

Setting Range:

Refer to parameter C4-01 in Appendix A for description details.
в—† C4-02 Torque Compensation Primary Delay Time
Setting Range:
0 ~ 10000 ms
Factory Default: 200 ms
The Torque Compensation function compensates for insufficient torque production at start-up and during low speed operation. The
iQpump drive will detect increases in the motor load by monitoring the output current and compensate by increasing the output voltage.
The increased output voltage leads to an increase in usable torque.
Parameter C4-01 sets the aggressiveness of the compensation for IR (resistive) and IL (inductive) losses in the motor windings, which are
more pronounced at lower speeds. Normally C4-01 does not need to be changed but may require adjustment in the following cases:
•
•
•
•
If the iQpump drive to motor cable is long, increase C4-01
If the motor capacity is smaller than the iQpump drive capacity, increase C4-01
If the low speed motor performance is unstable, decrease C4-01.
If the output current level exceeds the drive’s rated current while operating at low speeds, increase C4-01
Parameter C4-02 determines how quickly the Torque Compensation function will react to situations of insufficient torque. Again, C4-02
will not normally require adjustment except for the following situations:
• If the motor vibrates, increase C4-02
• If the motor response is sluggish (and possibly stalls), decrease C4-02
Important: Performing Auto-tuning can enhance low speed performance.

Parameter C6-02 sets the switching frequency of the drive’s output transistors. It can be changed in order to reduce audible noise and also
reduce leakage current. Cases that may require adjustment to the C6-02 are:
• If the wiring length between the iQpump drive and the motor is long, decrease the carrier frequency
Wiring Length
328 ft or less
Over 328 ft
C6-02 (carrier frequency) setting
1 ~ 4 (10 kHz max.)
1 ~ 2 (5 kHz max.)
• If speed and torque are inconsistent at low speeds, decrease the carrier frequency
• If leakage current from the iQpump drive is large, decrease the carrier frequency
• If the audible motor noise is too great, increase the carrier frequency (may require iQpump drive current derating)
When parameter C6-02 is set to “0: Low Noise” the iQpump drive uses a carrier frequency of 2 kHz and reduces the motor audible noise
by approximately 5 db. over the conventional 2 kHz setting (C6-02 = 1). The iQpump drive modulates the nominal PWM pattern to
achieve the lower noise. This setting is normally used with high starting torque loads that are frequently started and stopped or,
applications where leakage current needs to be minimized and motor audible noise is important.

The iQpump drive can be programmed to utilize digital inputs to change between four setpoint and a jog references. It is a two-step
process to set the iQpump drive up for setpoint point and jog references. First, d1-01 through d1-04 and d1-17 must be programmed with
the desired setpoint references and the desired jog reference, respectively. Next, up to three of the drive’s digital inputs (Terminals S3
through S7) need to be programmed (via parameters H1-01 to H1-05) and wired (to normally open contacts) as Multi-step SP1, Multistep SP2, and Jog Frequency.

• If b1-01 = “1: Terminals” then the analog input A1 will be used instead of Setpoint Reference 1 for the first preset Setpoint. If b1-01 =
“0: Operator,” then Setpoint Reference 1 will be used.
• If H3-09 = “2: Aux Reference” then the analog input A2 will be used instead of Setpoint Reference 2 for the second preset Setpoint. If
H3-09 = 2 then Setpoint Reference 2 will be used. This is only available when the iQpump drive is operating in the speed mode.
Important: The programming of d1-01 through d1-04 and d1-17 will be affected by the setting of P1-02 and o1-03, respectively. The
programming of these parameters will be in the units specified by Display Scaling parameter (P1-02 and o1-03).

Setting Range:

Factory Default: 0.0%
The use of parameters d2-01 and d2-02 places limitations on the speed command that the iQpump drive will accept. The parameters are
set in units of percentage of the maximum frequency (E1-04) and provide limits on any remote speed command input. By entering upper
or lower frequency limits, the iQpump drive programmer can prevent operation of the iQpump drive above or below levels that may cause
resonance, equipment damage or discomfort (see also parameter d3-0X). For example, limits may be needed to prevent low speed
operation of: Cooling tower fans with gear boxes, pumps with pressure dependent seals, or AHUs with minimum delivery requirements.

Unlike Frequency Reference Lower Limit (d2-02) which will affect the speed command no matter where it is sourced from (i.e. analog
input, preset speed, jog speed, etc.), the Master Speed Reference Lower Limit (d2-03) sets a low speed threshold that will only affect the
analog input that is the active master speed frequency (as determined by parameter H3-13 and H3-09). This parameter allows a minimum
speed to be programmed for the master reference while allowing a lower speed to be set as a jog reference. If the speed commanded by
the active master speed frequency is below the setting of d2-03, then the iQpump drive will operate at the speed specified by d2-03.

In order to avoid continuous operation at a speed that causes resonance in driven machinery, the iQpump drive can be programmed with
jump frequencies that will not allow continued operation within specific frequency ranges. If a speed is commanded that falls within a
dead band, or Jump Frequency, the iQpump drive will clamp the frequency reference just below the dead band and only accept higher
speed commands when the commanded speed rises above the upper end of the dead band, for increasing references. Similarly, the
iQpump drive will clamp the frequency reference just above the dead band and only accept lower speed commands when the command
speed falls below the lower end of the dead band, for decreasing references.

reached), and maximum frequencies.
There are also settings for Custom V/f patterns that will allow the programmer to manually set (“Customize”) the V/f pattern using
parameters E1-04 through E1-13.
Using parameter E1-03, the programmer can select one of the preset V/f patterns or chose between a custom V/f pattern with an upper

E2 Motor Setup
в—† E2-01 Motor Rated Current
Setting Range:
10% ~ 200%
Factory Default: Model Dependent
The Motor Rated Current parameter (E2-01) is necessary information for the iQpump drive motor protection function. The motor
overload protection parameter L1-01 is enabled by default. In addition, motor rated current is used by the torque compensation function
to insure optimum torque production. Set E2-01 to the full load amps (FLA) value stamped on the motor’s nameplate. During Autotuning, it is required for the operator to enter the motor rated current in parameter T1-04 on the Auto-Tuning menu. If the Auto-tuning
operation completes successfully, the value entered into T1-04 will be also written into E2-01.
For applications employing an iQpump drive that is oversized for the motor, E2-01 may be set as low as 10% of the iQpump drive output
current rating. The AMP value in E2-01, however, must always be greater than the “No Load Current” value in parameter E2-03 or an
OPE02 error will be displayed.
в—† E2-03 No Load Current
Setting Range:
Model Dependent (see Appendix B)
Factory Default: Model Dependent
Set E2-03 to the motor no-load current at rated voltage and rated frequency. Consult the motor manufacturer for the proper value if the no
load current is not stated on the motor nameplate.
в—† E2-04 Number of Motor Poles
Setting Range:
2 ~ 48 poles
Factory Default: 2 pole
This parameter sets the number of motor poles used for no-flow detection function and for the calculation of rpm-related parameters.
в—† E2-05 Motor Line-to-Line Resistance
Setting Range:
0.000 ~ 65.000 О©
Factory Default: Model Dependent
Sets the line-to-line resistance of the motor’s stator winding. Usually determined by performing Auto-tuning. If Auto-tuning cannot be
completed without error, then manually set E2-05 to the value as determined by the motor manufacturer. Remember this value must be
entered as line-line and not line neutral.

If a serial communication option board is attached to the iQpump drive at the 2CN connector, the iQpump drive will automatically
monitor the card for any type of communication errors. F6-01 is applicable no matter whether a run command or speed command is
coming via the option board, digital operator, or terminal input. The setting of F6-01 determines whether the communication error is seen
as a fault or an alarm. If F6-01 = “3: Alarm Only,” then the fault output is not energized upon a communication error. All other settings of
F6-01 cause the fault output to energize. The setting of F6-01 does not apply to any of the embedded communication protocols used at the
RS-485 / 422 terminals on the removable terminal board. (See parameters H5-0X.)

If an external fault is received from a communication option card, the settings of F6-02 and F6-03 will determine the iQpump drive
operation in reaction to the fault signal. Parameter F6-02 will determine if the external fault is always recognized (F6-02 = “0: Always
Detected”) or only recognized when the Run command is active (F6-02 = “1: Detected only during operation”).
Once the fault is recognized, parameter F6-03 will determine the operation of the drive. If parameter F6-03 is set to anything other then
“3,” the iQpump drive will fault and a stopping sequence is begun. If F6-03 = “3: Alarm Only,” then the external fault is treated like an
alarm. Operation will continue and an EF0 fault will flash on the digital operator.

Description
Function: 3-Wire Control (Setting: 0)
When one of the digital inputs is programmed for 3-Wire control, that input becomes a Forward / Reverse directional input. Whenever the
input is open, the iQpump drive will be set for forward rotation of the motor shaft. If the input it closed, then the motor shaft will rotate in
the reverse direction whenever a there is a Run input. The S1 and S2 digital inputs will function as a Run and Stop input respectively.

в– Function: Option / Inv Selection 1 (Setting: 2)
The Option / Inv Selection function allows the user to select the source for the Run and speed commands between either the drive’s
terminals or an optional communication card. When a digital input is programmed for the Option / Inv Selection function (H1-0x = 2)
that input will function as follows:
Table 22 Digital Input Functions
Option / Inv Selection Input Status
Run and Speed Command Source
CLOSED
From the control circuit and analog input terminals
OPEN
From the Communications Option Card
To switch the command source between the option card and the terminals be sure to program the following parameters:
• Set b1-01 (Auto Setpoint Reference Selection) to 1 (Terminals).
• Set
(Run Command Selection) to 1 (Terminals).
• Set H1-0x (Input Terminal Function Selection) to 2.
Important: Switching between the different Reference and Run sources can only be done while the iQpump drive is stopped.
в– Function: Multi-step SP1 (Setting: 3)
в– Function: Multi-step SP2 (Setting: 4)
The iQpump drive can be programmed to step through four preset setpoints and a jog reference. It is also possible to mix in the analog
inputs as setpoint references that can be chosen in place of the first and second preset setpoint references. The selection of which preset
setpoint will be the active setpoint is determined by the status of the digital inputs set for Multi-step SP1 (H1-0x = 3) and Multi-step SP2
(H1-0x = 4). Changing the active setpoint via the Multi-step Setpoint References can be done while the iQpump drive is running.
The following table details which reference is active based on the status of the Multi-step SP1 and Multi-step SP2 inputs:

The determination of whether the Preset Reference 1 will be the Setpoint Reference 1 (d1-01 or the analog input A1) is determined by the
status of b1-01. If b1-01 = “1: Terminals,” the value of the input to A1 will determine the commanded Setpoint when Preset Reference 1
is selected. If b1-01в‰ 1, the setting of d1-01 will determine the commanded Setpoint when Preset Reference 1 is selected.
The determination of Preset Reference 2 is made much the same way as Preset Reference 1 except that the setting of parameter H3-09
decides whether the analog input A2 or d1-02 is Preset Setpoint 2. If H3-09 = “2: Aux Reference,” the value of the input to A2 will
determine the commanded Aux Reference when Preset Reference 2 is selected. If H3-09 = 2, the setting of d1-02 will determine the
commanded setpoint when Preset Reference 2 is selected.

в– Function: Ext Baseblk N.O. (Setting: 8)
в– Function: Ext Baseblk N.C. (Setting: 9)
TIME
When the iQpump drive is commanded into baseblock, gating of the output transistor stops and output voltage/frequency drops to zero
(motor coasts). The iQpump drive can be forced into a baseblock state by either closing a digital input configured for Ext Baseblk N.O.
(H1-0x = 8) or opening a digital input configured for Ext Baseblk N.C. (H1-0x = 9).
When the baseblock state is removed the speed search function is used to catch the coasting motor and ramp it back to the commanded
speed.
The method of speed search, Current Detection or Speed Estimation, that is utilized when the baseblock input is removed depends on the
setting of parameter b3-01:
If b3-01 = “0: SpdsrchF Disable” or “1: SpdsrchF Enable”; Speed Estimation is used
If b3-01 = “2: SpdsrchI Disable” or “3: SpdsrchF Enable”; Current Detection is used

в– Function: Acc / Dec Ramp Hold (Setting: A)
The Acc / Dec Ramp Hold function will clamp (“hold”) the speed of the output frequency whenever a digital input that has been
programmed for it (H1-0x = A) is closed. All acceleration or deceleration will stop and the iQpump drive will hold the current speed.
Once the input is opened, acceleration or deceleration continues.
The Acc / Dec Ramp Hold function is affected by parameter d4-01. If d4-01 = “1: Enabled” and the Acc /Dec Ramp Hold functions are
both being used, whenever the RampHold input is closed the output frequency is memorized. When interrupted power is returned and a
Run command is input, the Speed Command will be the last output frequency memorized by the Acc / Dec Ramp Hold function, if the
Acc / Dec Ramp Hold input is still closed.

matter to the drive’s operation.

в– Function: MOP Decrease (Setting: 11)
Using two digital inputs, the iQpump drive can operate with the same type of functionality as a motor operated potentiometer (MOP).
One digital input can be programmed as an MOP Increase input (H1-0x = 10) and another digital input can be programmed as an MOP
Decrease input (H1-0x = 11). This MOP functionality is also commonly referred to as Floating Point Control, Incremental Control or UP
and DOWN Control since closing the MOP Increase input will cause the speed command to increase and closing the MOP Decrease
input will cause the speed command to decrease.
If both the MOP Increase and the MOP Decrease are closed or open simultaneously, the speed will command will not change. The speed
command will change at the active acceleration or deceleration rate.
MOP Increase cannot be programmed without also programming the MOP Decrease (or vice versa) else an OPE03 fault will occur.
Setting the MOP Increase / Decrease function while the Acc / Dec RampHold function is programmed into other digital inputs will also
cause an OPE03 fault.
Once the MOP function is programmed the preset speeds are disabled and the analog speed command input becomes a potential
frequency reference lower limit. The lower limit of the MOP function is the greater of the analog speed command and the programmed
frequency reference lower limit (d2-03). Once a Run command is issued the iQpump drive will accelerate immediately to the lower limit.
The upper limit will be the Frequency Reference Upper Limit (d2-01), if used, otherwise the Maximum Frequency (E1-04).
The status of the d4-01 parameter (MOP Reference Memory) will affect the performance of the iQpump drive after power is cycled to the
iQpump drive and a fresh Run command is issued. If d4-01 = “0: Disabled,” the Run command will cause the iQpump drive to ramp to
the frequency reference lower limit. However, if d4-01 = “1: Enabled,” the Run command will cause the iQpump drive to ramp to the last
speed commanded by the MOP function before the Run command was removed and the power cycled. Even if d4-01 = “1: Enabled,” the
62
YASKAWA TM.iQp.07 iQpump Controller Programming Manual
previous speed command can be reset to the frequency reference lower limit automatically by closing either the UP or Down input
without having a Run command active.
Important: Be sure to set b1-01 = “1: Terminals,” (Auto Setpoint = Terminals) if the MOP function is to be used. If b1-01 = “0:
Operator,” then the MOP is disabled even if it is programmed. The Jog inputs have priority over the MOP function.

в– Function: Fault Reset (Setting: 14)
Whenever the iQpump drive detects a fault condition, the fault output contact will close and the drive’s output will shut OFF causing the
motor to coast (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). Once the Run command is
removed, the fault can be reset by either the RESET key on the digital operator or by closing a digital input configured as a Fault Reset
(H1-0x = 14).
в– Function: Fast Stop N.O. (Setting: 15)
в– Function: Fast Stop N.C. (Setting: 17)
The Fast Stop function operates much like an emergency stop input to the drive. While in the Run mode, if a Fast Stop is input to the
iQpump drive (CLOSED for H1-0x = 15 or OPEN for H1-0x = 17), the iQpump drive will decelerate to a stop with the deceleration time
determined by C1-09 (Fast Stop Time). The Run command can remain closed during the Fast Stop operation. The iQpump drive will not
run, from either the terminals or the digital operator, while the Fast Stop is being input to the drive. To restart the drive, the Fast Stop input
must be removed and the Run command must be cycled.

Important: Be aware that during rapid deceleration the iQpump drive may fault on an over voltage condition. When faulted, the iQpump
drive output shuts off allowing the motor to coast. The result is an uncontrolled motor state. Therefore, be sure to set an acceptable
deceleration time in parameter C1-09 when using the fast stop feature.
в– Function: Timer Function (Setting: 18)
The Timer Function works independently from the drive. For Timer operation a digital input must be configured for a Timer Function
start (H1-0x = 18), a digital output must be configured as a Timer Function output (H2-0x = 12), and the Timer Function ON-Delay and
OFF-Delay parameters (b4-01 and b4-02, respectively) must be programmed.
Once the applicable parameter are programmed the Timer Function start digital input must be closed at least as long as the setting of b401 before the Timer Function output will close. The Timer Function input must be open for at least as long as the setting of b4-02 before
the Timer Function output will reopen.

в– Function: Program Lockout (Setting: 1B)
A Program Lockout digital input will allow changing of parameter values when it is open but prevent changing of any iQpump drive
parameter value except the Speed Command when it is closed. Parameter values can be viewed even when a Program Lockout is active.
в– Function: PI Disable (Setting: 19)
When the PI Function has been enabled by b5-01 (PI Mode Selection), it can be indefinitely disabled by closing a digital input configured
as a PI Disable input (H1-0x = 19). When disabled, the iQpump drive operates as a standard drive that does not have PI enabled.

YASKAWA TM.iQp.07 iQpump Controller Programming Manual
в– Function: External Fault (Setting: 20 through 2F)
External Fault functionality can be programmed into the digital inputs of the drive. The External Fault inputs can be used to signal to the
iQpump drive that other equipment related to the operation of the iQpump drive has experienced problems. If the External Fault is input
to the iQpump drive the digital operator will display as shown in the illustration below:
The x in EFx and Sx represent the terminal number of the digital input that the fault was received on.

Function: PI Integral Reset (Setting: 30)
By configuring one of the digital inputs as an Integral Reset Input, (H1-0x = 30), the value of the integral component of PI control can be
reset to zero whenever the configured input is CLOSED. The integral component of PI control will be held at zero as long as the
configured digital input is held CLOSED.
Resetting the Integral component of PI control can be useful in cases where an excessively large Integral value prevents the PI control
from responding quickly to changes in the system being regulated by the iQpump drive (e.g. duct pressure, water temperature).
Function: PI Integral Hold (Setting: 31)
By configuring a digital input as an Integral Hold input (H1-0x = 31), the value of the Integral component of the PI control can be forced
to clamp at the value it was at when the input is CLOSED. The Integral component of the PI control returns to accumulating error when
the digital input is OPEN again.
Holding the Integral Value can be useful during periods when the error can build up naturally, such as during long accelerations. Not
allowing Integral windup produces a more stable PI control.
YASKAWA TM.iQp.07 iQpump Controller Programming Manual
65
в– Function: PI SFS Cancel (Setting: 34)
SFS means softstart, also referred to as accel / decel in this description.
By configuring a digital input as a PI SFS (softstart) Cancel input (H1-0x = 34), the operator will be able to use a contact closure to
remove the acceleration and deceleration times that are applied to changes in the PI Setpoint by the b5-17 parameter. If the digital input
configured as PI SFS Cancel is closed, the PI Setpoint Accel / Decel (Parameter b5-17) will be ignored. Immediate updating of any
change to the setpoint will apply.
в– Function: Input Level Sel (Setting: 35)
When using the PI Function built into the drive, the chosen setpoint is compared with the measured feedback. The difference is called the
Error. The proportional and integral function are applied to this error. For some applications it may be appropriate to invert the input to
the PI block. This can be accomplished by setting one of the digital inputs up as an Input Level Sel (H1-0x = 35). When an Input Level
Sel digital input is closed the Error will be inverted before it is passed to the PI block.

в– Function: Option / Inv Sel 2 (Setting: 36)
The Option / Inv Selection function allows the user to switch the source of the Run and speed command between the drive’s terminals and
optional communication card. When a digital input is programmed for the Option / Inv Selection 2 function (H1-0x = 36) that input will
function as follows:
Table 25 Programming Choices
Option / Inv Function Input Status

To switch the command source between the option card and the terminals be sure to program the following parameters:
• Set b1-01 (Frequency Reference Selection) to 1 (Terminals).
• Set b1-02 (Run Command Selection) to 1 (Terminals).
• Set H1-0x (Input Terminal Function Selection) to 36.
Important: Switching the Reference and RUN sources can only be done while the iQpump drive is stopped.
в– Function: Motor Pre-heat (Setting: 60)
In order to prevent condensation on the motor windings, a DC current can be circulated through the windings. The heat produced by the
current in the windings will prevent the moisture from condensation on the wire. Motor pre-heating can only be initiated by closing a
digital input programmed as a Motor Pre-heat input (H1-0x = 60). The level of the DC current used by the Motor Pre-heat function is
determined by parameter b2-09.
A Run input will be given priority over a Motor Pre-heat input. When the Run command is removed, if the Motor Pre-heat input is still
closed, the motor pre-heating will resume.

The Speed Search function can be turned on for all starts with parameter b3-01. If, however, it is beneficial to only use Speed Search at
certain starts, a digital input can be programmed to turn on Speed Search only when it is closed.
Speed Search 1 will start searching for the rotor speed from the maximum frequency (E1-04). Speed Search 2 will begin searching for the
rotor speed from the existing Speed Command. Speed Search 3 will cause the motor to baseblock when the switch is open and then
perform Speed Search when it closes.
In all cases the form of Speed Search, Speed Estimation or Current Detection, is determined by the setting of b3-01. If b3-01 = “0:
SpdsrchF Disable,” then the Speed Estimation form of Speed Search is used. If b3-01 = “2: SpdsrchI Disable,” then the Current Detection
form of Speed Search is used.
в– Function: Comm Test Mode (Setting: 67)
The iQpump drive has a built-in function for self-diagnosing the serial communications operation. The test involves wiring the send and
receive terminals of the RS-485 / 422 port together. The iQpump drive transmits data and then confirms the communications are received
normally.
In order to perform the serial communications self-diagnosis, terminal S7 must be programmed as the Comm Test Mode digital input
(H1-05 = “67: Com Test Mode”) and then power removed from the iQpump drive and the following steps performed:
1. Wire the S7 and SC terminals of the control circuit terminals together

в– Function: Drive Enable (Setting: 6A)
A digital input configured as an iQpump drive Enable input (H1-0x = 6A) will prevent the iQpump drive from executing a Run command
until it is closed. When the iQpump drive Enable input is open the digital operator will display:
-DRIVE-
DNE
Drive Not Enable
If a Run command is closed prior to the iQpump drive Enable input being closed the iQpump drive will not run until the Run command is
cycled.
If the iQpump drive Enable input is opened while the iQpump drive is running, the iQpump drive will stop, using the method set by
parameter b1-03.
в– Function: Com / Inv Sel (Setting: 6B)
в– Function: Com / Inv Sel 2 (Setting: 6C)
The Com / Inv Selection function allows the user to switch the origin of the Run and speed command between the drive’s terminals and
the RS-485 / 422 port (and the embedded communication protocols) on the removable terminal board. When a digital input is
programmed for the Com / Inv Selection function (H1-0x = 6B) that input will function as follows:
Table 27 6B, COM / INV SEL
Option / Inv Function Input Status
Run and Speed Command Source
OPEN
From the control circuit and analog input terminals (follows b1-01)
CLOSED

To switch the command source between the serial communication port and the control circuit terminals be sure to program the following
parameters:
• Set b1-01 (Auto Setpoint Reference Selection) to 1 (Terminals).
• Set b1-02 (Run Command Selection) to 1 (Terminals).
• Set H1-0x (Input Terminal Function Selection) to 6B or 6C.
The Com / Inv Sel 2 function will operate the same way except the logic is reversed. When a digital input is programmed for the Com /

Function: Hand Mode (Setting: 80)
A digital input can be configured to operate the drive in the hand mode from an external contact as a Hand Mode command (H1-0x = 80).
In conjunction with the digital input programmed to hand mode, the run command source has to be programmed to 1 (b1-02 = 1:
Terminals).
The multi-function digital input terminal S6 is programmed for Hand Mode as a factory default (H1-04 = 80).

в– Function: Disable Sleep Mode (Setting: 81)
A digital input can be configured to enable or disable the Sleep Mode (H1-0x = 81). The Sleep Mode is only active when the drive is in
the Auto Mode. A contact closure into the multi-function digital input will disable the Sleep Mode. Also, the Feedback Drop Detection
and Over Cycle Protection will also be disabled. When the digital input is open, the Sleep Mode, Feedback Drop Detection and Over
Cycle Protection will be enabled.

в– Function: Activate Sleep (Setting: 82)
A digital input can be configured to activate the Sleep Mode (H1-0x = 82) when the drive is operating in the Auto Mode. A contact
closure into the multi-function digital input will cause the drive to go to sleep for the time specified by the Sleep Delay Time (P2-03).
When the digital input is open, the drive will return to normal operation. Refer to the P2 group for further description of the Sleep
function.
Note: Oscillation can occur if Sleep is activated by using the digital input and Sleep Feedback Drop Detection is enabled and
detected. It is recommended to disable Sleep Feedback Drop Level (P2-04) or program a long Sleep Delay Time (P2-03)
and a large Delta Sleep Feedback Drop Level (P2-04).

в– Function: Thermostat Fault (Setting: 83)
A digital input can be configured to indicate a Thermostat Fault from an external contact (H1-0x = 83). A contact closure into the multifunction input will enable the Thermostat Fault. After an initiation of a Thermostat Fault, to disable the Thermostat Fault requires a open
digital input contact, the drive run command to be open and reset the Thermostat Fault via the drive's reset button or fault reset input.
Note: An OPE12 fault will occur if H1-xx = 83 and 87. H1-xx cannot be programmed to “83” and “87” at the same time.

в– Function: Disable Pre-charge (Setting: 84)
A digital input can be configured to enable or disable the Pre-charge function (H1-0x = 84). A contact closure into the multi-function
digital input will disable the Pre-charge function independent of the value programmed into the Pre-charge Time (P4-03). When the
digital input is open, the Pre-charge function is enabled.
в– Function: Low Water Level (Setting: 85)
A digital input can be configured to indicate a Low Water Level Fault (H1-0x = 85). The Low Water Level input can be configured as a
normally open or normally closed contact by programming the Water DI Config (P1-15). When P1-15 = 0 or 2, a Low Water Level Fault
will occur when the contact is closed (normally open). An open contact will indicate the drive is operating under normal operating
conditions.
When P1-15 = 1 or 3, a Low Water Level Fault will occur when the contact is open (normally closed). A closed contact will indicate the
drive is operating under normal operating conditions.
If the Pre-charge function is activated, the Low Water Level will not cause a Low Water Level Fault. The Low Water Level will only
indicate that the Pre-charge function has been completed.
If the drive is operating under normal operating condition and a Low Water Level occurs, the drive will indicate a Low Water Level Fault
(LFB / LW) on the digital operator.

To reset the Low Water Level Fault would require the removal of the run command, initiate a fault reset, and restart the drive using the
Pre-charge function.
IMPORTANT: <0034>
Program P1-15 to 0 or 2 when the “Low Water” function is not used.
Note: Low Water Level Fault is only active in the Auto Mode and inactive during the Pre-charge function.

в– Function: Freq Detect 1 (Setting: 4)
A “Freq Detect 1” output will be closed whenever the output frequency is equal to or below the value of the programmed Speed Agree
Level (L4-01). The Speed Agree Width (L4-02) is the hysteresis to the Freq Detect 1 function. Whenever the output frequency
approaches the Speed Agree Level while accelerating it will need to be equal to or exceed the Speed Agree Level (L4-01) plus the Speed
Agree Width (L4-02) before the Freq Detect 1 output will energize.
As the output frequency approaches the Speed Agree Level while decelerating, the Freq Detect 1 output will de-energize exactly at the
Speed Agree Level.
The Freq Detect 1 function is effective during both forward and reverse operation.

в– Function: Inverter Ready (Setting: 6)
The Inverter Ready output will be closed whenever the iQpump drive is not in a fault state and not being programmed. If b1-08 = “1:
Enabled,” an iQpump drive that is in an active Run state that is also being programmed will have the Inverter Ready output closed.
в– Function: DC Bus Undervolt (Setting: 7)
The DC Bus Undervolt output will close whenever the main circuit DC Bus voltage or control circuit power supply drop below their
respective trip level. The undervoltage trip level is determined by parameter L2-05. An open soft charge contactor answer back signal will
also cause the DC Bus Undervolt output to close.
в– Function: BaseBlk 1 (Setting: 8)

в– Function: Option Reference (Setting: 9)
When an output is configured as an Option Reference output, the output will close to show that the speed command is being sourced from
the digital operator. If the Option Reference output is open, it indicates the speed command is coming from the control circuit terminals
or an optional communications card.
в– Function: Remote / Auto Operation (Setting: A)
When an output is configured as a Remote Operation output, the output will close to show that the Run command is being sourced from
the digital operator. If the Remote Operation output is open, it indicates the Run command is coming from the control circuit terminals or
an optional communications card.
в– Function: Trq Det 1 N.O. (Setting: B)
The Trq Det 1 function ties a digital output to the overtorque / undertorque sensing capabilities of the drive. If a digital output is

в– Function: Loss of Reference (Setting: C)
The Loss of Reference configured digital output will close when the iQpump drive has detected a loss of the analog speed command. The
speed command is considered lost when the voltage level drops 90% in 0.4 seconds. Parameter L4-05 determines the drive’s reaction to a
loss of reference state in addition to turning on the Loss of Reference digital output.
The Loss of Reference digital output will only initiate if the iQpump drive is configured for the speed command to be via one of the
analog inputs (A1 or A2).

в– Function: Minor Fault (Setting: 10)
A Minor Fault, also referred to as an alarm, indicates that a condition exists that may be critical to the iQpump drive or application but
does not require the iQpump drive to stop. A minor fault will be flashed on the digital operator but neither the Fault output (MA-MB) nor
any digital output configured as a Fault output (H2-0x = E) will close. Any digital output configured as Minor Fault will close whenever
a minor fault of alarm condition exists.
в– Function: Reset Cmd Active (Setting: 11)
A Reset Cmd Active digital output will close to signal that a Fault reset is being attempted from terminals or Serial Com.
в– Function: Timer Output (Setting: 12)
This Timer function, that is built into the drive, is independent of the rest of the iQpump drive operation, i.e. there is no requirement for a
Run command for the timer to operate. A Timer digital output will close b4-01 seconds after a digital input configured as Timer Input
(H1-0x = 18) closes and remains closed. The Timer digital output will remain closed for b4-02 seconds after the Timer digital input opens
and remains open.
Refer to the descriptions of parameters b4-01 and b4-02 for a timing chart of the Timer function.
Function: Trq Det 1 N.C. (Setting: 17)
The Trq Det 1 function ties a digital output to the overtorque / undertorque sensing capabilities of the drive. If a digital output is
configured as Trq Det 1 N.C., whenever the output current exceeds the level of L6-02 for at least the length of time set in L6-03, the
digital output will open.
The torque detection function has a built-in hysteresis of 10% of the iQpump drive rated output current.

в– Function: Restart Enabled (Setting: 1E)
Depending on the setting of parameter L5-01, the iQpump drive may be configured to automatically attempt to restart itself after certain
faults. The Restart Enabled output will be closed once the restarts begin and will remain closed until a successful restart is accomplished
or the number of Auto Restart attempts as specified by L5-01 is reached.
A timing diagram for the Auto Restart function is contained in the parameter L5-01 description.
в– Function: Overload (OL1) Alarm (Setting: 1F)
The OL1 fault function is designed to protect the motor. It estimates the motor’s winding temperature based on the output current, output
frequency, and time. The OL1 time is determined by the setting of parameters E2-01, L1-01, and L1-02. An Overload digital output will
close whenever 90% of the programmed OL1 time is exceeded.
в– Function: OH Prealarm (Setting: 20)
The Overheat fault function (OH) is designed to protect the iQpump drive from excessive temperature damage. Thermistors attached to
the heatsink of the iQpump drive monitor the temperature near the devices attached to the heatsink (e.g. input diode modules, output
transistor modules) and will fault the drive if the temperature reaches 105oC.
An OH Prealarm digital output will close whenever the heatsink temperature reaches the level specified by parameter L8-02. Parameter
L8-03 will determine the drive’s response to reaching the OH Prealarm level, in addition to closing the configured digital output.
в– Function: Drive Enabled (Setting: 38)
A iQpump drive Enable digital output will reflect the status of a digital input configured as an iQpump drive Enable input (H1-0x = 6A).
If the iQpump drive Enable digital input is closed then the iQpump drive Enabled digital output will also close.
в– Function: Drive Waiting (Setting: 39)
A iQpump drive Waiting digital output will close during the time-out period between the input of a Run command and the expiration of
the delay time specified by b1-11.
в– Function: Frequency Reduced, OH (Setting: 3A)
A Frequency Reduced, OH digital output will close when L8-03 = “4:OH Alarm and Reduce” and an overheat pre-alarm is detected.
в– Function: Run from Serial Com (Setting: 3B)
A Run from Serial Com digital output will close when the drive run command is from embedded serial com or the com option card.
в– Function: Pump 2 Control (Setting: 40)
The multi-function digital output is configured to enable a second lag pump based on the normal operating conditions of the iQpump,
which determines when the second lag pump should be activated or deactivated. The operation of the digital output is determined by the
programming of the Pump Mode selection (P1-01).
If P1-01 = 0, the iQpump is programmed for drive only; therefore, the Pump 2 Control output will be deactivated.
If P1-01 = 1 or 2, the iQpump will activate the Pump 2 Control output based on normal operating conditions.

в– Function: Pump 3 Control (Setting: 41)
The multi-function digital output is configured to enable a third lag pump based on the normal operating conditions of the iQpump, which
determines when the third lag pump should be activated or deactivated. The operation of the digital output is determined by the
programming of the Pump Mode selection (P1-01).
If P1-01 = 1 or 2, the iQpump is programmed for drive only or drive + 1 pump; therefore, the Pump 3 Control output will be deactivated.
If P1-01 = 2, the iQpump will activate the Pump 3 Control output based on normal operating conditions.

H3 Analog Inputs
Note: To convert terminal A1 to a 4-20 mA signal, connect a 250 Ohm precision resistor (1/4 Watt or greater) between A1 and
AC. Then program H3-02 = 231.3% and H3-03 = -25.0%.

Setting Range:
-100.0% ~ +100.0%
Factory Default: 0.0%
In order to have the iQpump drive properly interpret an analog input, it may be necessary to apply a gain and / or a bias to the signal. The
analog inputs have a resolution of 10 bits (1024 steps). Using the factory default settings for the analog input’s gain and bias, the 0-10
Vdc or 4-20 mA signal at the analog input will yield a 0-100% speed command span.

If a different span of analog input signal is desirable, it will be necessary to adjust the gain, the bias, or both to allow the analog input
level to generate the desired frequency command. Adjustment of the gain setting will change the speed command that is equivalent to the
maximum analog input (10 Vdc or 20 mA). If, for instance, the gain is increased to 200%, then 10 Vdc or 20 mA will be equivalent to a
200% speed command and 5 Vac or 12 mA will be equivalent to a 100% Speed Command. Since the iQpump drive output is limited by
the maximum frequency parameter (E1-04), 0-5 Vdc or 4-12 mA will now be equivalent to 0-100% speed command span.

Adjustment of the bias setting will likewise adjust the speed command that is equivalent to the minimum analog input level (0 Vdc or 4
mA). If, for instance, the bias is set to –25%, then 0 Vdc or 4 mA will be equivalent to a –25% speed command. Since the minimum
speed command is 0% an analog input of 2 to 10 Vdc or 7.2 to 20 mA will now be equivalent to 0-100% speed command span.

As a further example, for an inverse-acting speed command, set the bias = 100% and the gain = 0%. The minimum analog input level (0

The H3-08 parameter (Terminal A2 Signal Level) allows the programmer to specify the signal that will be applied to the A2 analog input.
The A2 analog input can accept either a 0–10 Vdc or 4-20 mA signal as a reference. The iQpump drive also has a DIP switch (S1) on the
removable terminal board that must be set for the proper reference signal into the A2 analog input. The S1-2 dipswitch setting determines
the internal resistance of the A2 input while parameter H3-08 determines how the iQpump drive interprets the measured signal.

The A2 analog input can be programmed to perform many different functions. The setting of parameter H3-09 determines which of the
following functions the A2 analog input will perform.
в– Function: Frequency Bias (Setting: 0)
By setting H3-09 = “0: Frequency Bias,” the A2 analog input will serve as a bias signal to the A1 Speed Command. The effect of using
A2 for a frequency bias is that the level of the A2 analog input will be summed with the level of the Speed Command analog input (A1).
For example, if H3-02 = 100%, H3-03 = 0%, and the A2 analog input level is 1 Vdc, the Speed Command profile will look like Figure 77.
below. If A1 = 0 Vdc the Speed Command would be 10% of the programmed maximum frequency because A1 (0 Vdc) + A2 (1 Vdc) = 1

Figure 77. Effect of Frequency Bias Function on Speed Command
It should be noted that the bias applied by the A2 analog input functions differently than the level set by the H3-03. If both biases are used
simultaneously they will sum together.
The level of the A1 analog input, as a percentage of the maximum input (either 10 Vdc or 20 mA), can be viewed by the U1-15 monitor.
The level of the A2 analog input, as a percentage of the maximum input, can be viewed by the U1-16 monitor.
The bias applied by setting H3-09 = “0: Frequency Bias,” can be used in conjunction with the parameter bias H3-03. In that case the H303 bias is applied first which changes the slope of the Speed Command vs. Terminal A1 Voltage graph. Then the level of the A2 analog
input is summed with the A1 analog input level, which in effect shifts the Speed Command vs. Terminal A1 Voltage graph upwards or
downwards but does not change the slope of the line.

в– Function: Aux Reference (Setting: 2)
In order for the A2 analog input to be used as the master Speed Command, parameter H3-09 must be set for Aux Reference (H3-09 = “2:
Aux Reference”). Once A2 is configured as an auxiliary reference, it can be selected as the master Speed Command by setting H3-13 =
“1: Main Fref TA2”. If H3-09 = 2, terminal A2 analog input will become the speed command when a digital input programmed for MultiStep Ref 1 (H1-0x = 3) is selected by a contact closure.
в– Function: PI Feedback (Setting: B)
Configuring the A2 analog input as PI Feedback (H3-09 = “B: PI Feedback”) is a requirement of setting the iQpump drive up for PI
operation. The A2 analog input is the only source for feedback for PI operation though the setpoint can come from a number of different
sources (refer to the section covering the PI parameters for more information regarding specifying the setpoint source. PI parameters are
listed in “b5 PI Function” on page 32).
Parameters H3-10 (Terminal A2 Gain) and H3-11 (Terminal A2 Bias) can be used to configure the A2 analog input to match the signal
from the Feedback Transmitter.
The U1-24 monitor (PI Feedback) can be used to check the PI Feedback level with the digital operator.
в– Function: Frequency Bias 2 (Setting: D)
By setting H3-09 = “D: Frequency Bias 2,” the A2 analog input will serve as a bias signal to the A1 Speed Command. This setting
functions the same as a setting of H3-09 = 0: Frequency Bias.

в– Function: Motor Temperature (Setting: E)
In addition to or in place of the OL1 (Motor Overload) fault of the drive, it is possible to use a PTC (Positive Temperature Coefficient)
thermistor for motor insulation protection. The PTC thermistors are built into the windings of some motors and will vary their resistance
based on temperature. An example PTC characteristic is show below.

below.
Figure 81. Thermistor to Drive Connection Diagram
After the connections are made, configure the A2 analog input for motor temperature protection by setting H3-09 = “E: Motor
Temperature”. Parameters L1-03, L1-04, and L1-05 set the response to the alarm level being exceeded, response to the fault level being
exceeded, and temperature sensing delay time, respectively.
The proper value of the branch resistance is approximated by the formula:
Rbranch =
(Rptc@Trx3) x (VS -Vptc@OH3)
Vptc@OH3
Where: (Rptc@Tr x 3) = The resistance value of the thermistor at either the alarm or fault level adjusted for three phase (three thermistors in
series, refer to typical PTC thermistor characteristic in Figure 81.).
VS = The supply voltage (+15 Vdc)
Vptc@OH3 = The rated voltage for the over-temperature alarm or fault
в– Function: PI Differential (Setting: 16)
Normal PI operation will adjust the iQpump drive output in order to match the measured feedback value to a desired setpoint. When PI is
operated in the differential mode, however, the iQpump drive output is adjusted in order to maintain a desired differential between two
feedback signals. Air handling unit return fan speed control in a “volume snatching” strategy for building pressure control is an example.
When the A2 analog input is configured as a PI Differential (H3-09 = “16: PI Differential”), the A1 analog input becomes the other PI
Differential input. The desired differential is set by parameter b5-07 (PI Differential Setpoint) and can be set so that A2 is held less than
A1 (b5-07 <0) or A2 is held greater than A1 (b5-07>0).
When PI Differential operation is chosen, the A1 feedback level can be monitored by U1-24 (PI Feedback) and the A2 feedback level can
be monitored by U1-53 (PI Feedback2).
в– Function: Not Used (Setting: 1F)
When H3-09 = “1F: Not Used,” any signal applied to the A2 analog input will be ignored by the drive.

An analog input filter can be used to prevent erratic iQpump drive control when a “noisy” analog reference is used. Parameter H3-12 sets
the time constant for a first order filter that will be applied to both the A1 and A2 analog inputs. The iQpump drive operation becomes
more stable the longer the time programmed, but it becomes less responsive to rapidly changing analog signals.

в– Function: Frequency Ref (Setting: 1)
The analog output level will correspond to the chosen Speed Command input whether it is input via the digital operator, analog input, or
serial communication. 100% will be equivalent to the maximum output frequency of the iQpump drive (E1-04).
в– Function: Output Freq (Setting: 2)
The analog output level will correspond to the actual Speed being output by the iQpump drive and will include the acceleration and
deceleration ramps. 100% will be equivalent to the maximum output frequency of the iQpump drive (E1-04).
в– Function: Output Current (Setting: 3)
The analog output level will correspond to the output current level of the drive. 100% will be equivalent to the drives rated output current
which is based on the kVA Rating of the iQpump drive (o2-04).
в– Function: Output Voltage (Setting: 6)
The analog output level will correspond to the output voltage level of the drive. 100% will be equivalent to either 200 Vac or 400 Vac
depending on the input voltage rating of the drive.
YASKAWA TM.iQp.07 iQpump Controller Programming Manual

в– Function: DC Bus Voltage (Setting: 7)
The analog output level will correspond to the voltage level of the drive’s DC bus. 100% will correspond to 400 Vdc for the 240 Vac input
iQpump drive and 800 Vdc for the 480 Vac input drive.
в– Function: Output kWatts (Setting: 8)
The analog output level will correspond to an internally calculated output power level based on the measured output current and output
voltage. 100% will correspond to the kilowatt rating of the iQpump drive as determined by o2-04.
в– Function: Term A1 Level (Setting: 15)
The analog output level will correspond to the analog input to the drive’s A1 terminal. 100% will be equivalent to 10 Vdc.
в– Function: Term A2 Level (Setting: 16)
The analog output level will correspond to the analog input to the drive’s A2 terminal. 100% will be equivalent to 10 Vdc.
в– Function: Mot SEC Current (Setting: 18)
The analog output level will correspond to the calculated secondary (torque producing) current. 100% will be equivalent to motor’s full
load secondary current as calculated by:
I s = в€љ О™ Nameplate 2 - I no load 2
= в€љ (E2-01) 2 - (E2-03) 2
в– Function: SFS (Softstart) Output (Setting: 20)
The analog output level will correspond to the Speed Command after the applicable acceleration and deceleration rates are applied. The
SFS (Softstart) Output monitor will not include variations to the Speed Command other than the acceleration and deceleration ramps.
100% will be equivalent to the maximum output frequency of the iQpump drive (E1-04).
в– Function: PI Feedback (Setting: 24)
The analog output level will correspond to the analog input to the drive’s A2 terminal during normal PI operation but will correspond to
the A1 analog input when the A2 analog input is configured as a PI Differential input (H3-09 = “16: PI Differential”). The output will
function even if PI operation is not selected (b5-01 = “0: Disabled”). Parameter b5-20 will apply a gain to the measured analog output
voltage before the monitor is displayed.
(i.e. with b5-20 = 5 the 2 Vdc feedback signal will generate 10 Vdc on the analog output).
в– Function: Not Used (Setting: 31)
When H4-01 = “31: Not Used” no voltage is output by the analog output.
в– Function: PI Input (Setting: 36)
The analog output will correspond to the measured error of the PI function. The measured error of normal PI operation is the setpoint
minus the feedback. The measured error of the differential PI is the difference between the A1 and A2 analog inputs summed with the PI
differential setpoint). The output will not function unless PI operation is selected (b5-01в‰ 0).
в– Function: PI Output (Setting: 37)
The analog output will correspond to the output of the PI function. The PI output will be measured after any gains, offsets, or limits are
applied to the output of the Proportional and Integral factors. The output will not function unless PI operation is selected (b5-01в‰ 0) and
there is an active Run command. 100% will be equivalent to maximum frequency (E1-04).
в– Function: PI Setpoint (Setting: 38)
The analog output will correspond to the level of the chosen setpoint of the PI function. Please refer to table on page 32 included in the
section PI Control (b5 parameters) for more information about selecting the PI Setpoint source. The output will not function unless PI
operation is selected (b5-01в‰ 0).

The gain and bias parameters for the analog outputs of the iQpump drive allow the programmer to customize the output signal for the
equipment connected to the output. The analog outputs are adjustable over a range of 0-10 Vdc. The gain settings for the analog outputs
determine the output voltage level that will be equivalent to 100% of the Monitor Function Level. A gain setting greater than 100% will
produce 10 Vdc on the analog output when the monitor function is less than 100%.
For example, if H4-02 = 150%, then the FM analog output will produce 6.7 Vdc when the assigned output function initially reached the
100% level.

в—† MEMOBUS / Modbus Communication Configuration
MEMOBUS / Modbus communication is configured using 1 master (PLC) and a maximum of 31 slaves. Serial communication between
master and slave is normally initiated by the master and responded to by the slaves.
The master performs serial communication with one slave at a time. Consequently, the slave address of each slave must be individually
set, so that the master can perform serial communication using that address. Slaves receiving commands from the master perform the
specified functions, and send a response back to the master.

1. The factory setting for CRC-16 communication is typically zero, but when using the MEMOBUS / Modbus system, set the factory
setting to one (e.g., set all 16 bits to 1).
2. Calculate CRC-16 using MSB as slave address LSB, and LSB as the MSB of the final data.
3. Calculate CRC-16 for response messages from the slaves and compare them to the CRC-16 in the response messages.

в– Enter Command
When writing parameters to the iQpump drive from the PLC using MEMOBUS / Modbus communication, the parameters are
temporarily stored in the constant data area in the drive. To enable these parameters in the parameter data area, use the Enter command.
There are two types of Enter commands:
1. Enter commands that enable parameter data in RAM
2. Enter commands that write data to EEPROM (non-volatile memory) in the iQpump drive at the same time as enabling data in RAM.
The following table shows the Enter command data. Enter command data can only be written.
The Enter command is enabled by writing 0 to register number 0900 or 0901.

Parameter data is not written to EEPROM, but refreshed in RAM only.
Important: The maximum number of times the EEPROM can be written using the iQpump drive is 100,000. Do not frequently execute
Enter commands (0900) written to EEPROM.
The Enter command registers are write-only. Consequently, if reading these registers, the register address will become invalid (Error
code: 02).

MEMOBUS / Modbus Self-Diagnosis
в– The iQpump drive has a built-in function for self-diagnosing the operations of serial communication interface circuits. The self-diagnosis
function connects the communication parts of the send and receive terminals, receives the data sent by the drive, and checks if
communication is being performed normally.
Perform the self-diagnosis function using the following procedure.
1.
2.
3.
4.
5.
Turn ON the power supply to the drive, and set parameter H1-05 (Terminal S7 Function Selection) to 67 (Comm Test Mode).
Turn OFF the power supply to the drive.
Perform wiring according to the following diagram while the power supply is turned OFF.
Turn ON the terminating resistance. (Turn ON pin 1 on DIP switch 1.)
Turn ON the power supply to the iQpump drive again.
Figure 1.91
Figure 95. Communication Terminal Connection for Self -Diagnosis Function
6. During normal self-diagnostic operation, the Digital Operator displays the frequency reference value. If an error occurs, a CE
(MEMOBUS / Modbus communication error) alarm will be displayed on the Digital Operator, the fault contact output will be turned
ON, and the iQpump drive operation ready signal will be turned OFF.

In order for a master to be able to communicate with the iQpump drive using serial communications, the iQpump drive must have a
unique node address. The iQpump drive is given a node address if H5-01в‰ 0. The node addresses do not have to be assigned in sequential
order but they must be unique, i.e. no two drives on the same serial network can be assigned the same address. After setting the iQpump
drive address with the H5-01 parameter, the power to the iQpump drive must be cycled for the addressing to take effect.
Leaving H5-01 = 0 will disable responses to MEMOBUS / Modbus communications.

Parameters H5-02 and H5-03 configure the drives MEMOBUS / Modbus communications via the RS-485 / 422 terminals on the
removable terminal block. Configure H5-02 and H5-03 to match the settings of the master controller of the serial network. After changing
the H5-02 or H5-03 parameter, the power to the iQpump drive must be cycled for the change to take effect.
If either the speed or parity value is changed via the serial communications, the serial communications will cease to operate until the
iQpump drive power is cycled.
It may be necessary to avoid the 19.2 K baud setting if frequent serial communications errors occur at that baud rate.

The setting of parameter H5-04 will determine the drive’s reaction to a serial communications fault such as the CE fault. The iQpump
drive can be programmed to either ramp to a stop in the time specified by C1-02 (H5-04 = “0: Ramp to stop”), coast to a stop (H5-04 = 1),
ramp to a stop at the special fast stopping time specified by C1-09 (H5-04 = “2: Fast-Stop”), or continue operating using the commands
received before the serial communication fault and flashing an alarm on the digital operator (H5-04 = “3: Alarm Only”).
в– H5-05 Communications Error Detection Selection
Setting
Description
0
Disabled
1
Enabled (factory default)
The iQpump drive can be configured by parameter H5-05 to recognize a CE fault whenever serial communications time-out. If H5-05 =
“1: Enabled,” the iQpump drive will fault if serial communication responses are not received within a set period of time determined by
parameter H5-09. iQpump drive power should be cycled after a change is made to this parameter.
в– H5-06 Drive Transit Wait Time
Setting Range:
5 ~ 65 ms
Factory Default: 5 ms
Parameter H5-06 will set the delay time between the receiving of a message from the master and the sending of a response from the
iQpump drive back to the master. The iQpump drive power should be cycled after a change is made to this parameter.
в– H5-07 RTS Control Selection
Setting
Description
0
Disabled (RTS is always on)
1
Enabled (RTS turns on only when sending) (factory default)
RTS or Request To Send control is a method of flow control applied to messaging in serial communications. Parameter H5-07 configures
whether the iQpump drive will implement RTS messaging all the time (H5-07 = “0: Disabled”) or only when sending (H5-07 = “1:
Enabled”). It is recommended to set H5-07 = “0: Disabled,” when using RS-485 and set H5-07 = “1: Enabled,” when using RS-422. The
iQpump drive power should be cycled after a change is made to this parameter.

FLN (APOGEE)
Since the iQpump drive is capable of using MEMOBUS / Modbus, Metasys N2, or Apogee FLN communications via the RS-485 / 422
terminals, parameter H5-08 must be programmed to specify to the iQpump drive which format is being used. iQpump drive power should
be cycled after a change is made to this parameter.
YASKAWA TM.iQp.07 iQpump Controller Programming Manual
109
в– H5-09 Communication Error Detection Time
Setting Range:
0.0 ~ 10.0 s
Factory Default: 2.0 s
The setting of parameter H5-09 determines the length of time that serial communications must be lost before a CE fault occurs. Setting
H5-09 = 0 will configure the iQpump drive for the quickest CE fault detection but may cause nuisance faults. The iQpump drive power
should be cycled after a change is made to this parameter.

Setting
Description

Std Fan Cooled (Enabled) (factory default)
The iQpump drive has an I2t electronic overload protection function, the OL1 fault, for protecting the motor from overheating. The
iQpump drive bases the protection on time, output current, and output frequency. The electronic thermal overload function is ULrecognized so an external thermal overload relay is not required.
If the iQpump drive is connected to a single motor, the motor overload protection should be enabled (L1-01 = “1: Std Fan Cooled”) unless
another means of preventing motor thermal overload is provided.
The time before the OL1 fault will occur changes as the output frequency is reduced. The maximum output current level at which there is
no time limit for operation (the OL Start Point) is different depending on the output frequency. For instance, if the iQpump drive is being
operated at 60 Hz and the output current level is below 106% of the motor’s rated current (E2-01), the iQpump drive will run without an
OL1 fault indefinitely. Once the 106% output current level is exceeded, de-rating of the OL1 time starts.

The iQpump drive can be programmed to accept a PTC (Positive Temperature Coefficient) Thermistor input for monitoring motor
temperature. By setting parameter H3-09 = “E: Motor Temperature,” and attaching the PTC thermistor per the Figure 98. below, the
iQpump drive can react to the increasing motor winding temperature with both an alarm (L1-03) and a fault (L1-04).

Using the changing voltage drop across the thermistor the voltage into the A2 analog input will vary according to the motor’s winding
temperature. If the measured voltage into A2 exceeds 1.17 Vdc the iQpump drive will flash an OH3 alarm on the digital operator and will
either ramp to a stop in the time specified by C1-02 (L1-03 = “0: Ramp to Stop”), coast to a stop (L1-03 = “1: Coast to Stop”), ramp to a
stop at the special fast stopping time specified by C1-09 (L1-03 = “2: Fast-Stop”), or continue operating using the commands received
before the OH3 alarm (L1-03 = “3: Alarm Only”). The drive’s fault contact, MA-MB, will not close.
If the measured voltage into the A2 analog input exceeds 2.34 Vdc the iQpump drive will fault (OH4) and either ramp to a stop in the
time specified by C1-02 (L1-04 = “0: Ramp to Stop”), coast to a stop (L1-04 = “1: Coast to Stop”), ramp to a stop at the special fast
stopping time specified by C1-09 (L1-04 = “2: Fast-Stop”). The drive’s fault contact, MA-MB, will close.
Parameter L1-05 will apply a time delay filter to the A2 analog input when it is configured as the thermistor input. The greater the time
programmed into L1-05 the less responsive the iQpump drive will be to quick changes to the input voltage but the more stable the input
will be. A noisy input will benefit from a greater L1-05 time.

L2 Momentary Power Loss Ride-thru Function
When momentary power loss recovery is enabled (L2-01в‰ 0), a speed search is executed to catch the potentially spinning motor shaft.

в—† L2-02 Momentary Power Loss Ride-Thru Time
Setting Range:
0.0 ~ 25.5 s
Factory Default: Model Dependent
The iQpump drive allows different responses to momentary power losses. The setting of L2-01 determines whether the iQpump drive
attempts to restart after a short loss of incoming AC power and for what length of time this capability remains active.
If L2-01 = “0: Disabled,” the iQpump drive detects a UV1 fault 15 ms after power loss and automatic restarting is disabled. The iQpump
drive cannot restart until the external run command is removed and the UV1 fault is reset.
If L2-01 = “1: PwrL Ride Thru t,” the iQpump drive restarts without the UV1 fault if power is returned within the time specified in L2-02,
the Momentary Power Loss Ride-thru Time. During the power loss but before the fault trip, the digital operator will display a UV alarm.
If L2-02 is set for a time longer than the control power supply can be sustained, a UV1 fault will not occur and the iQpump drive restarts
upon the return of AC power. The time that the control power supply can be maintained varies with iQpump drive size. The larger the
drive, the greater the potential ride-thru time.
If L2-01 = “2: CPU Power Active,” the iQpump drive ignores L2-02 and attempts a restart as long as the control power supply is still able
to maintain a minimal voltage level. In effect, setting L2-01 = “2: CPU Power Active” (factory default) is programming the iQpump drive
for maximum Power Loss Ride-thru. An equivalent setting is L2-01 = “1: PwrL Ride Thru t,” with L2-02 set to a time longer than the
control power supply can be maintained after power is lost.
Note: The run command must be held during power loss for any power loss ride-thru capability to be possible. It is for this
reason that 3-wire control is not recommended for use with the Momentary Power Loss function.
в—† L2-03 Momentary Power Loss Minimum Baseblock Time
Setting Range:
0.1 ~ 5.0 s
Factory Default: Model Dependent
When momentary power loss recovery is enabled (L2-01в‰ 0) the iQpump drive will baseblock for a period of time specified by the L2-03
parameter. The baseblock time will be executed just prior to the speed search function in order to allow any residual magnetic fields in the
motor windings to decay before any new voltage is applied to the motor.
If the motor’s secondary circuit time constant is known, set L2-03 = 0.7x (value of time constant). If an OC or OV fault occurs during
momentary power loss recovery, increase the setting of L2-03.
The L2-03 parameter also sets the baseblock time for the DC Injection Braking function (b1-03 = “2: DC Injection to Stop”). If an OC or
OV fault occurs during DC Injection Braking to Stop, increase the setting of L2-03.
в—† L2-04 Momentary Power Loss Voltage Recovery Ramp Time
Setting Range:
0.0 ~ 5.0 s
Factory Default: Model Dependent
When momentary power loss recovery is enabled (L2-01в‰ 0), a speed search is executed to catch the potentially spinning motor shaft. As
part of the speed search function full voltage is not immediately applied to the motor but is ramped up. The setting of parameter L2-04
determines the ramp time for increasing the output voltage from zero to maximum voltage (E1-05).
If a UV1 fault occurs during the current detection speed search function, increase the setting of L2-04.

в—† L2-05 Undervoltage Detection Level
Setting Range:
150 ~ 210 Vdc
Factory Default: 190 Vdc
The L2-05 parameter sets the DC Bus undervoltage level. The setting of L2-05 affects the voltage at which a UV alarm or a UV1 fault
will occur. If the setting of L2-05 is lowered below the factory default level (190 Vdc for a 240 Vac drive and 380 Vdc for a 480 Vac
drive), then an AC Input Reactor must be installed on the input AC line to prevent inrush current from damaging the drive’s input diodes.
An AC Line dip and fast voltage recovery can potentially cause a large inrush current.

The stall prevention during acceleration function adjusts the acceleration time in order to prevent OC fault trips during acceleration. If
L3-01 = “0: Disabled,” stall prevention is disabled. If the load is large enough and the acceleration time short enough the iQpump drive
may fault and stop.
If L3-01 = “1: General Purpose,” then the standard stall prevention function is enabled. When the output current exceeds the level set by
the L3-02 parameter, the iQpump drive will discontinue accelerating and maintain speed. If, during acceleration, the output current comes
within 15% of the level set by parameter L3-02, the acceleration time is lengthened. Once the output current level has dropped below the
L3-02 level, acceleration will begin again with the acceleration rate reaching the programmed rate once again 15% below the L3-02 level.

If L3-04 = “1: General Purpose,” then the standard stall prevention function is enabled. If, during deceleration, the DC Bus voltage
exceeds the stall prevention level (see Table 43 on page 120), the iQpump drive will discontinue decelerating and maintain speed. Once

The Stall Prevention During Running function will attempt to avoid an iQpump drive OC fault occurrence while the iQpump drive is
operating at a constant speed. If L3-05 = “0: Disabled,” the iQpump drive may fault if the load increases sufficiently to cause the output
current to reach the OC fault level (180% of the iQpump drive rated output current).
If L3-05 = “1: General Purpose,” the iQpump drive is outputting a constant speed, and the drive’s output current level exceeds the level set
by parameter L3-06 for more than 100 ms the iQpump drive will begin to decelerate at the rate specified by parameter C1-02. The
iQpump drive will continue to decelerate until the output current level drops below the L3-06 level (less a 2% hysteresis). Once the output
current drops below the L3-06 – 2% level the iQpump drive will begin to accelerate at the currently active acceleration rate (either C1-01
or C1-03).
If L3-05 = “2: Decel Time 2,” the iQpump drive will function as described above except C1-04 will be used instead of C1-02 as the
deceleration rate used when the output current exceeds L3-06 for more than 100 ms.

All major faults will cause the iQpump drive to stop. For some faults it is possible to configure the iQpump drive to attempt a restart
automatically. After the fault occurs, the iQpump drive baseblocks for the Maximum Restart Time After Fault programmed in L5-03.
After the baseblock is removed the iQpump drive checks if a fault condition still exists. If no fault condition exists the iQpump drive will
attempt to restart the motor. If the restart is successful, the iQpump drive performs a Speed Search (Regardless of the status of b3-01
“Speed Search Selection”) from the set speed command and the Auto Restart Attempts count is increased by one. Even if the restart fails
the restart count is increased by one as long as the iQpump drive attempted to rotate the motor. The restart count will not be incremented
if the restart is not attempted due to a continuing fault condition, (i.e. an OV fault). The iQpump drive waits the Maximum Restart Time
After Fault (L5-03) before attempting another restart. This parameter is not applicable to Loss of Prime Fault.

The iQpump drive can be programmed to indicate when either an overtorque or an undertorque conditions exist. A digital output must be
programmed for “Torque Detection,” (H2-01 / H2-02 = “B: Trq Det 1 N.O.” or “17: Trq Det 1 N.C.). A warning of an overtorque
condition can indicate a jam and an undertorque condition can indicate a broken belt, no water in a pump, or other loss of load.
To configure Torque Detection requires the following decisions:
1. Is an overtorque condition or an undertorque condition being checked?
2. Is the torque condition present when the drive is running or only at speed agree? Nuisance detection during acceleration, when variable
torques are normally required, can be avoided.
3. Is the drive to fault if the torque condition is detected or only alarm and continue operation?
The following table can help choose the proper setting for Torque Detection Selection 1 to get the wanted results.

current transformers rises above (overtorque) or drops below (undertorque) this level, and remains there for at least the Torque Detection
Time (L6-03), then the Torque Detection Function will change the state of any digital output configured for Torque Detection (H2-01 /

OH Alarm and Reduce (factory default)
The iQpump drive is capable of warning the operator of an impending heatsink over-temperature fault via an oH pre-alarm. The level at
which the pre-alarm will activate is determined by the setting of parameter L8-02. Measurement of the heatsink temperature is done with
several strategically mounted thermistors. If any of the heatsink thermistors measure a temperature in excess of the setting of L8-02, the
iQpump drive will fault (oH2) and either: ramp to stop using the C1-02 deceleration rate (L8-03 = “0: Ramp to Stop”), coast to stop (L803 = “1: Coast to Stop”), ramp to stop using the C1-09 fast stop deceleration rate (L8-03 = “2: Fast-Stop”), alarm (oH) and continue
running (L8-03 = “3: Alarm Only”), alarm (oH) and continue running but at a reduced speed (L8-03 = “4: Alarm and Reduce”). If L8-03
= 4: Alarm and Reduce, the iQpump drive will continue to run but will reduce the speed to the level determined by parameter L8-19.
Refer to the description for parameter L8-19.
If a digital output is configured for OH Prealarm (H2-01 = “20: oH PreAlarm”), it will close whenever the heatsink temperature is greater
than the L8-02 level no matter what the setting is of L8-03.

Description
Disabled
Enabled (factory default)
The input phase loss detection circuit monitors the DC bus current ripple and activates when one of the input phases is lost. The detection
circuit calculates the maximum and minimum values of the DC bus voltage in one second intervals, and compares the difference (DV)
between these values with an internal detection level. If DV reaches or exceeds the detection level, after 0.5 second, the input phase loss
is detected; a PF fault occurs and the motor coasts to a stop.
Input phase loss detection is disabled in the following cases:
•
•
•
•
•
A Stop command is input
Magnetic Contactor (MC) shuts OFF
CPU A/D converter fault (CPF5)

в—† L8-06 Input Phase Loss Detection Level
Setting Range:
0.0 ~ 25.0% of Drive O V Trip point
Factory Default: kVA Dependent
The iQpump drive checks for a lost input phase by monitoring the DC Bus voltage ripple. After an initial delay of approximately 12
seconds, the iQpump drive will sample the DC BUS voltage every 1.28 seconds to determine the minimum and maximum voltage
readings. The difference between the minimum and maximum voltage is averaged over ten consecutive scans. If this “averaged” value is
greater than the trip level as determined by L8-06 (L8-06 x 400 for 200 V class drives; L8-06 x 800 for 400 V class drives) the iQpump
drive shuts down and displays “PF,” an input phase loss fault.

The output phase loss detection circuit monitors the DCCT and activates when one or more of the output phases are lost. The detection
circuit calculates the RMS current value (IRMS) for each of the phases and compares it with an internal output detection level. If IRMS
decreases to or below the detection level for 10 seconds, an output phase loss (LF) fault occurs and the motor coasts to a stop.

The iQpump drive has a ground fault detection circuit that activates when the current to ground exceeds 50% of the drive’s rated output
current. The current to ground is determined by comparing the measured current on each of the output phases. If the current to ground is
determined to be above 50% of the drive’s rated output current the digital operator will display a GF and the iQpump drive will coast to
stop.

в—† L8-11 Heatsink Cooling Fan Operation Delay Time <0033>
Setting Range:
0 ~ 300 s
Factory Default: 300 s
Parameters L8-10 and L8-11 allow the iQpump drive programmer to customize the heatsink cooling fan operation. Parameter L8-10
determines whether the cooling fans are always ON whenever the iQpump drive is powered (L8-10 = “1: Fan Always On”) or if the
cooling fans are only ON when the iQpump drive is in a Run condition (L8-10 = “0: Fan On-Run Mode”).
Parameter L8-11 is a delayed OFF for the cooling fan if L8-10 = “0: Fan On-Run Mode”. When the cooling fans are set to turn OFF is
when either the Run command is removed or the drive is in baseblock. The iQpump parameter L8-11 will cause the fans to continue
cooling the iQpump drive for the amount of time programmed into L8-11 after the Run command is actually removed or baseblocked
enabled. The iQpump drive can be programmed to allow the cooling fan to run for up to 5 minutes (factory default) after the run
command is removed or baseblock enabled.
Both parameters are intended to extend fan life while still providing sufficient cooling for proper iQpump drive operation.

At very low speeds (6 Hz and below) and very high current levels it can be possible to damage output transistors. Therefore the factory
default setting of L8-15 is to shorten the time before an OL2 fault will occur during low speed / high load situations (L8-15 = “1:

Description
Disabled
Enabled (factory default)
The Soft CLA (software current limit level) is an iQpump drive protection function that will limit the drive’s output current. The iQpump
drive limits the output current by reducing the output frequency whenever the current exceeds 110% of the inverter rated current If the
current level drops below the Soft CLA level, then normal operation will continue.
If the software current limit is disabled (L8-18 = “0: Disabled”), the iQpump drive may trip on an OC fault if the load is prohibitively
large or the acceleration is too short. For proper iQpump drive protection and operation leave the Soft CLA function enabled.
в—† L8-19 Overheat Frequency Reference Reduction Level
Setting Range:
0.0 ~ 100.0% of maximum frequency
Factory Default: 20.0% of maximum frequency
When the heatsink temperature reaches the OH Pre-alarm level (L8-02) and the Overheat Pre-Alarm Operation Selection parameter is set
for Alarm and Reduce (L8-03 = “4: OH Alarm and Reduce”), the L8-19 parameter sets the amount of speed decrease that will be applied
to the Speed Command in order to lower the heatsink temperature. The decrease in speed will lower the current being switched and
conducted by the heat producing output transistors of the drive.
Parameter L8-19 is set in percentage of maximum frequency (E1-04).

в—† n1-02 Hunting Prevention Gain Setting
Setting Range:
0.00 ~ 2.50
Factory Default: 1.00
Sometimes when the iQpump drive is lightly loaded and the carrier frequency is high, the drive’s output current may vary, or hunt. This
varying current can cause the motor to vibrate. The drive’s Hunting Prevention function can stabilize the motor’s magnetizing current by
adjusting the output voltage (n1-01 = “1: Enabled”). The Hunting Prevention function can eliminate the vibration but at the cost of the
iQpump drive response.
Parameter n1-02 can adjust the gain of the Hunting Prevention function if it is enabled by n1-01. Normally there is no need to adjust
n1-02 from the factory default setting. Make adjustments in the following cases:
• If vibration occurs with a light load, increase the setting of n1-02.
• If the motor stalls, reduce the setting of n1-02.
An overly large Hunting Prevention Gain (n1-02) may cause the motor to stall.

When the iQpump drive is powered up, three monitors are displayed on the digital operator. The first and largest monitor is the “PowerOn” monitor. The factory default “Power-On monitor” is Speed Command (U1-01). Below the Speed Command monitor are the next two
sequential monitors, Output Frequency (U1-02) and Output Current (U1-03). Pressing the INCREASE key once scrolls the monitors to
show the User Monitor as selected by o1-01. The factory default for o1-01 is the Output Voltage monitor (U1-06).
The active monitor displayed when the iQpump drive is powered on can be changed to either be U1-01 (Speed Command), U1-02
(Output Frequency), U1-03 (Output Current), or the User Monitor. Whichever monitor is selected as the Power-On top monitor, the two

The iQpump drive gives the option of configuring any and all of the programming parameters and then saving the parameters as “User
Initialization Values”. After configuring the drive, set parameter o2-03 = “1: Set Defaults,” to save the parameters to a User Initialization
memory location. Once this has been done, the “Initialize Parameters” parameter (A1-03) will offer the choice of “1110:User Initialize”.
Choosing A1-03 = “1110: User Initialized,” will reset all modified parameters back to what they were the last time they were saved using
o2-03.
The choice of setting A1-03 = “1110: User Initialized,” is unavailable until first setting the User Initialization parameters using o2-03.
Once a User Initialization is set (saved), it can be cleared by setting o2-03 = “2: Clear All”. After clearing the User Initialization
parameters, the choice of “1110: User Initialize” is no longer a available in A1-03.

The factory default setting of the Frequency Reference Setting Method parameter (o2-05 = “1: Enabled”) dictates that when setting a
Speed Command via the digital operator (“Hand” mode), it is not necessary to press the DATA / ENTER key before the iQpump drive
will begin to accelerate or decelerate to the new set speed. This is referred to as MOP (Motor Operated Potentiometer) type functionality.
When o2-05 = “1: Enabled,” the speed command is stored to memory 5 seconds after the INCREASE or DECREASE keys are released.
When o2-05 = “0: Disabled,” the digital operator INCREASE and DECREASE keys will change the speed command but the iQpump
drive will not accelerate or decelerate to the new speed command until the DATA / ENTER key is pressed. In order to change the Speed
Command in the HAND mode, U1-01 must be the top monitor and then the ENTER key must be pressed in order to access the Speed
Command function. This in not to be confused with pressing the ENTER key in order to achieve a change in speed using the INCREASE

when viewing the “Modified Constants” menu. To VERIFY the parameter values in the iQpump drive as compared with those stored in
the digital operator, set o3-01 = “3: OP↔INV VERIFY”. During the comparing of the parameter values into the iQpump drive the digital
operator will display:
-ADV-
VERIFY
DATA VERIFYING
A successful VERIFY of the parameter values will display:
-ADV-
VERIFY
VERIFY COMPLETE
If all the parameter values stored in the digital operator do not match those programmed in the drive, the digital operator displays the
following:
-ADV-
VYE
VERIFY ERROR
The digital operator will not display which parameters did not match, only that the verification found discrepancies in some parameter
values.
Note: In order to properly use the COPY or VERIFY functions, the following iQpump drive specifications must be identical
between the iQpump drive that the parameters were read from and the iQpump drive that the parameters are to be
written to:
• Model Number (e.g. CIMR-P7U2015-107)
• Software Number (e.g. 30030 also known as FLASH ID)
Yaskawa offers DriveWizardв„ў software that can also READ, COPY, and VERIFY iQpump drive parameter values. DriveWizardв„ў lists
all discrepancies between the iQpump drive and a pre-saved parameter file when verifying is performed.
To use DriveWizard first select o2-15 = “0: Disabled” and select o2-06 = “0: Disabled” then remove the digital operator / keypad and
attach the DriveWizard cable in its place.

Lead-Lag Operation P1-01 Setting 1 & 2
The iQpump drive can be configured to specify the number of pumps to be controlled by programming the Pump Mode (P1-01). The
maximum number of pumps that can be controlled is 3 pumps (1 lead and 2 lag). The iQpump can be configured for lead-lag operation
where 1 pump is controlled by the iQpump drive's output (lead) and the other two pumps controlled by the drive's digital outputs (M1M2, M3-M4) or lag operation.
To control the two lag pumps requires the multi-function digital outputs (H2-0x) to be programmed for Pump 2 Control (H2-01 = 40) and
Pump 3 Control (H2-01 = 41).
Note: The factory defaults for the digital outputs (H2-0x) are programmed for Pump 2 and Pump 3 Control.
Auxiliary Pump Control P1-01 Setting 1 & 2
The iQpump drive can be configured to control multiple pumps with multiple iQpump drives by programming the Pump Mode (P1-01).
The maximum number of pumps that can be independently controlled is 3 pumps.
To configure an Auxiliary Pump Control system requires the first drive to be programmed for drive + 1 (P1-01 = 1) and the second drive
(last) for drive only (P1-01 = 0). The multi-function digital output (M1-M2) needs to be programmed for Pump 2 Control (H2-01 = 40).
The first drive starts to run and brings the second drive online based on the pump system demand. The moment the second drive starts
running, the multi-function digital output (M1-M2) closes.
The multi-function digital output provides an input command (Terminal S7 and SN) to the first iQpump drive and initiates a Fixed Speed
Auto function on the first drive (H1-05 = 86).
When the Fixed Speed Auto input is closed, the first drive will run at a fixed speed without PID control. When the second drive goes to
sleep, the Fixed Speed Auto input opens and the first drive starts operating under normal pump control.
When using the iQpump drive to control 3 pumps, all of the drives need to be daisy chained in a similar configuration. The last drive
always has to be programmed for drive only (P1-01 = 0) and the other drives for duplex mode (P1-01 = 1).

L4-01).
в—† MEMOBUS / Modbus Communication <0034>
The current iQpump software only allows the drive to be a slave on a MEMOBUS / Modbus Network which means that an external
device such as a computer or PLC needs to be connected to the network and issue commands to the drives. Having a drive act as a
MEMOBUS / Modbus Master eliminates the need for an external master and introduces better drive control since it can be configured for
either a general or specific application feature.

в—† MEMOBUS / Modbus Communication Configuration P1-01=3 <0034>
Figure 1.108
Figure 112. Example of Connections between Master and Drive <0034>
This change will allow the drive to function as a MEMOBUS / Modbus Master on the RS-485 interface and issue commands to the
MEMOBUS / Modbus slaves based on their current status. A new mode, MEMOBUS / Modbus Network, will be added to P1-01. When
the drives are running in this mode, as long as at least one of the drives is set to Automatic Network Recovery (P9-27 = 0), a MEMOBUS
/ Modbus Master will be active. The MEMOBUS / Modbus Master will read from and write to a predefined set of addresses for proper
operation of the iQpump system. A maximum of 16 iQpump drives (with node addresses 1 to 16) can be operated in this manner. To
maximize network performance, a new parameter Highest Node Address (P9-25) can be programmed to be the node address limit. Drives
with node address beyond this parameter will be ignored.
Network recovery in the event that the master is lost, is also possible when Automatic Network Recovery is used.
в– System Faults with P1-01=3 <0034>
When P1-01 = 3 (MEMOBUS / Modbus Network), the following faults are considered system faults and work as described below:
Low Feedback / Low Water: Active on any drive in the network. When a drive incurs the LFB/LW fault, it will stop all other drives on
the network, and prevent them from running until the fault is cleared. The system message “Net Pump Err” is displayed on all other
network drives.
High Feedback / High Water: Active on the lead drive in the network. When the lead incurs the HFB / HW fault, it will stop all other
drives on the network, and prevent them from running until the fault is cleared. The system message “Net Pump Err” is displayed on all
other network drives.
Flow Meter: Low Flow, High Flow and Accumulated Level: Active on any drive in the network that has an Auto Run command. When
the drive incurs the fault (LOWFL, HIFLO, ACCUM), the network will stop all other drives and prevent them from running until the fault
is cleared. The system message “Net Pump Err” is displayed on all other network drives.
Setting System Fault Restart P9-22 to zero disables restarting of any system fault regardless of L5-01, Feedback Fault Restart P4-07, and
Protection Fault Restart P4-08 parameter settings. However, if P9-22 > 0, but L5-01 = 0 or P4-07 / P4-08 is set to disable the fault restart,
then if that drive gets a system fault, the system will not be able to restart.
Whenever a drive with a system fault auto-restarts the network System Fault Restart counter gets incremented and the L5-01 fault restart
counter does not get increased. If the system fault restart counter becomes equal to P9-22, the iQpump MEMOBUS / Modbus Network
will disable automatic fault restart. Manually resetting the fault will clear the system fault restart counter. If the iQpump MEMOBUS /
Modbus Network does not experience a system fault for 10 minutes, it will clear the system restart fault counter.

в—† Function Description: MEMOBUS / Modbus Communication
When P1-01 = 3 (Pump Mode = MEMOBUS / Modbus Network), the drive will either become a Master or Slave, depending on P9-27
(Network Recovery). In addition, H5-01 (Serial Comm Address) is range limited by P9-25 (Highest Node Address). Setting P9-27 to
anything other than 0 (Automatic) will force that drive to never become a Master Network controller. When P9-27 = 0, the drive will
attempt to become a Master whenever P9-26 (Master Time-out) expires. A fixed amount of time (node address H5-01 x 0.25 s) is always
added to P9-26 to minimize network collision resulting from multiple drives attempting to become a master at the same time.
If P9-27 = 0 at start-up, the drive uses a different Master Time-out which is based on the node address:
Initial Master Time-Out (in seconds) = 1.5 + (node address H5-01 x 0.25)
If P9-27 в‰ 0, then P9-26 is used as the Master Time-Out at start-up.
So, if P9-27 = 0 for all the networked drives, logically when power is restored to the drives at the same time the drive with the lowest node
address will always become the Master drive initially (see Figure 112.). Once a drive either becomes a master or receives data from it, the
start-up process is concluded and the drives use P9-26 plus a fixed number (node address H5-01 x 0.25 s) as the Master Time-out.
The drive that becomes a master during the start-up process will attempt to query the drives starting from address 1 up to P9-25 (Highest
Node Adr). If it gets a good response from the query, the drive gets added to the Network Active Pumps list. Drives in the Network Active
Pumps list are given network commands and refreshed regularly through the MEMOBUS / Modbus Sequencer.
Node addresses that are not part of the Network Active Pumps list, but are within the P9-25 range are queried regularly and added if they
become online. Nodes that are part of the Active list, but do not reply to the network commands are removed from the list.
In the event that the master goes down, another drive (P9-27 = 0) can assume master functionality after the Master Time-out expires. The
new master will use data from Pumps Available list to rebuild the network data. If the data suggests that there is an available drive on the
network, then the new master will not do a complete scan. It will also skip writing commands to the active drives until it performs a read
on the current Pump Status, which is then used to recreate the previous command given to that drive. However if the data suggests that
there no available drive, then it will do complete scan of all the valid node addresses.
A new master will perform Network Restore, which attempts to run the drives as they were before the old master went down by using the
drive’s current status. Additionally, if Network Restore encounters ambiguity, such as multiple lead drives running at the same time, it
will attempt to resolve the conflict following normal operation flow.
Setting P9-27 = 1 (Slave / Resume) prevents the drive from becoming a network master and at the same time will not cause a MSL fault
if the master does go down. It will continue running using the last command received.
Note: The drive will keep running in its current operation state which could cause an undesirable condition.
Setting P9-27 = 2 (Slave / Resume) prevents the drive from becoming a network master and at the same time will not cause a MSL fault
if the master does go down. It will continue running when the master is lost.
Setting P9-27 = 3 (Fault MSL) will fault the drive after P9-26 expires.
Parameter P9-28 (NETSCAN Alarm Time) can be varied to control the amount of time before a NETSCAN alarm is displayed after the
last time a message from the master has been received. High network latency or having a lot of offline drives will require a higher setting.
An offline drive is defined as a pump with node address within 1 to P9-25 that does not have power, has connection issues, or is
disconnected physically form the network.
More detailed information regarding functionality can be found in VSP130034-DD.

Time (P1-05) after an Auto Mode run has been initiated.
If this parameter is set to a non-zero value and a run command is present within 1 second of power being applied to the drive, the start of
the drive will be delayed. Presumably, multiple drives fed off of the same utility feed would have their timers set to different times.
Note: The Start Delay Time will function only after a stop command due to the no-flow detection or sleep detection functions.
Removing the enable signal does not activate the Start Delay.

The iQpump drive can be configured to display a Not Maintaining Setpoint (NMS) fault when the difference between the setpoint and the
feedback exceeds the Maximum Setpoint Difference (P1-11). When the Maximum Setpoint Difference has been exceeded, the drive will
trip on NMS fault and will coast to a stop when the fault occurs.
The faults Not Maintaining Setpoint (NMS), Loss of Prime (LOP), High Feedback / High Water (HFB / HW), Low Feedback / Low
Water (LFB / LW), Low Flow (LOWFL), High Flow (HIFLO), and Accumulated Level (ACCUM) are considered System Faults. When
these faults occur, all the drives in the network need to be stopped and prevented from running until the fault is cleared or autorestarted.<0034>
When a system fault is detected on a drive, the iQpump MEMOBUS / Modbus Network sends out a system message to all other drives
informing them of the fault, stopping any drives that are running, and preventing any drives from running until the fault is no longer
present. Resetting the fault on the drive will clear the message.<0034>
When Fault Restarts are enabled (L5-01 > 0, P4-07 and P4-08 set appropriately), system faults do not consume L5-01 attempts, but
instead uses a new parameter P9-22 System Fault Retry. The system fault retry attempts apply to all the drives on the network and gets
incremented when a drive with a system fault auto-restarts. For proper operation, P9-22 should be set the same for all drives on the
iQpump MEMOBUS / Modbus Network (P1-01 = 3).
Setting P1-11 to a value of 0 will disable this function. This function is only active during operation in the Auto Mode.
The Maximum Setpoint Difference (P1-11) works in conjunction with the Not Maintaining Setpoint (P1-12). The units for this parameter

The iQpump drive can be configured to display a Not Maintaining Setpoint (P1-12) fault when the difference between the setpoint and
the feedback levels are exceeded for the time programmed in the Not Maintaining Setpoint (P1-12). The drive will coast to a stop after the
level has been exceeded for the specified time programmed in P1-12.
This function is only active during operation in the Auto Mode.
The Not Maintaining Setpoint Time (P1-12) is also used for the Prime Loss Level (P1-14) function. Refer to Prime Loss Level (P1-14)
for more details.
The Not Maintaining Setpoint Time (P1-12) works in conjunction with Maximum Setpoint Difference (P1-11) and Prime Loss Level (P114).
Note: The time value programmed into P1-12 is shared by Maximum Setpoint Difference (P1-11) and Prime Loss Level
(P1-14) functions. However, independent times are maintained. If one function time; such as P1-11, has elapsed, the
other functions time (P1-14) is still maintained until this time has elapsed.
Not Maintaining Setpoint: The “Not Maintaining Setpoint” detection is now the only thing that parameter P1-12 controls. Also, the
“Not Maintaining Setpoint” timer is held reset during the pre-charge function to prevent erroneous operation.
• P1-12 is only effective for the “Setpoint Not Met” fault.
• “Setpoint Not Met” is disabled during pre-charge.

The iQpump drive can be configured to enter a “sleep” condition based on output frequency. The drive will enter the sleep mode when the
output frequency falls below the programmed Sleep Level (P2-02) for a time specified by the Sleep Delay Time (P2-03).
This function is only active during operation in the Auto Mode. The display will indicate “Sleep” alarm when active.
The Sleep Level Type works in conjunction with the Sleep Level (P2-02), Sleep Delay Time (P2-03), and Alternative Sleep Activate
Level (P2-20). A multi-function digital output can be programmed to enable sleep (H1-xx = 82).
The sleep boost feature will only operate in simplex mode (P1-01 = 0) or in multiplex mode (P1-01 > 0) with just one drive running.
Note: If the value programmed into Alternative Sleep Activate Level (P2-20) is greater than 0.0 Hz, the sleep function will
become active when the output frequency rises above the programmed Sleep Level (P2-02) and above the programmed
Alternative Sleep Activate Level (P2-20). It is recommended that P2-20 be programmed 1 or 2 Hz above the P1-06
value. The sleep level using P2-20 enables the sleep mode; however, the drive still enters sleep based on P2-20. With the
normal default sleep level programmed in P2-02, the sleep cycle will not activate until the output frequency is above
P2-02.
в– Function Description: <0034>
Sleep Level Type = Motor Speed (rpm): When parameter P2-01 = 3, the drive will respond exactly the same as if P2-01 = 0 (Output
Frequency), except the sleep level parameter will now display units of “rpm” instead of “Hz”.
Sleep Level Type = Low Flow: When parameter P2-01 = 4, the drive will go to sleep based on the flow meter input. See the portion of
the specification that describes the flow meter for details.
Sleep Boost: The Sleep Boost function is intended to be used with a pump / pressure-tank system. In order for the sleep boost function to
activate, the following conditions need to be met:
- PI control must be active (b5-01 > 0)
- PI control must NOT be inverted (b5-09 в‰ 1)
- Sleep must be enabled (P2-02 > 0.0)
- Drive must be running in “AUTO MODE” (not Hand or Local control)
- Sleep Boost function must be enabled (P2-21 > 0.0)
- Must be in simplex mode (P1-01 = 0) or must have just one drive running in multiplex mode (P1-01 > 0)
When the sleep boost function is enabled and the conditions are met for the drive to go into sleep, the P2-03 timer will then complete. At
that time, the setpoint will be increased by the amount entered into parameter P2-21. In order for the drive to go into sleep, the system
must reach the boosted setpoint for at least 0.5 seconds, or the time set into parameter P2-22 must expire.
Note: The Sleep Boost Timer will NOT start timing until after the P2-03 sleep delay timer has expired.

YASKAWA TM.iQp.07 iQpump Controller Programming Manual
в– No-Flow Detection Basic Operation
The iQpump drive can be configured for a no-flow detection condition. The no-flow detection function of the iQpump drive is an
advanced feature for all pumping applications. The typical applications for this function are submersible and booster station pumps.
The programming of the No-Flow Activation Level (P2-11) will activate the no-flow detection function. The drive will monitor the motor
rpm and if the motor rpm falls below the No-Flow Activation Level (P2-11) and the No-Flow Detection Bandwidth (P2-12), the no-flow
process is activated.
The drive will check for system response by monitoring the motor rpm for a time specified by the No-Flow Detection Time (P2-13). If the
motor rpm is within the bandwidth programmed in P2-12 after the time specified by P2-13, the setpoint will be lower by the value
programmed in the No-Flow Setpoint Compensation (P2-16). The drive will wait for the system to stabilize for the time programmed in
the No-Flow Stabilization Time (P2-14).
After the time programmed in P2-14 has elapsed, the setpoint is returned to the original value. The drive will again wait for the system to
stabilize for the time programmed in P2-13. If the time programmed in P2-13 has elapsed, the drive will continue to monitor the feedback
level. If the feedback level falls within the No-Flow Delta Feedback Level (P2-15) for a time programmed in No-Flow Feedback Delay
Time (P2-17), the drive will enter a “sleep” mode after the P2-13 time elapses.

The iQpump drive can be configured for lead-lag control. The lead-lag control refers to the drive (lead) controlling a pump and turning on
auxiliary pumps (lag) by the drive’s output contacts. The controlling of the auxiliary pumps is referred to staging and de-staging. Up to
three (3) total pumps can be operated, one lead (drive control) and two auxiliary pumps. The pump control staging and de-staging can be
controlled by three (3) different lead-lag control methods.
0: Output Frequency
1: Feedback Level
2: Output Frequency + Feedback Level
в– P3-01 = 0: Output Frequency
The “output frequency” control method monitors the drive’s output frequency and determines if the auxiliary pumps need to be staged
(turned ON) to maintain the programmed system’s setpoint. The output frequency also determines when the auxiliary pumps are to be destaged (turned OFF). Refer to Figure 129. and Figure 130. for the staging and de-staging of the auxiliary pumps using the “output
frequency” control method.
Auxiliary Pump Staging (ON)
The staging of auxiliary pump 2 occurs when the output frequency remains above the iQpump drive Multi / Maximum Level (P3-02) for
the time programmed in Add Pump Delay Time (P3-04).
The staging of auxiliary pump 3 occurs when the auxiliary pump 2 is staged and the output frequency remains above the iQpump drive

Factory Default: 0.0 Hz
The iQpump drive can be configured for multiplex pumping operation. The pump system may experience an increase of friction when
additional pumps are staged (turned ON). The level when the additional compensation for friction losses can be programmed into the
Friction Compensation Start Frequency (P3-13). This function will activate when the output frequency rises above the Friction
Compensation Start Frequency (P3-13). The maximum compensation at Maximum Output Frequency (E1-04) is specified by the
Maximum Friction Increase at Maximum Frequency (P3-14).
The Friction Compensation Start Frequency (P3-13) works in conjunction with the Maximum Friction Increase at Maximum Frequency
(P3-14).
Note: This function is only active when the Pump Mode (P1-01) is set to 0.

P4 Pump Advanced
в—† P4-01 Pre-charge Level
Setting Range:
0.0 ~ 6000.0
Factory Default: 0.0
The iQpump drive can be configured for special functions for dedicated pumping applications. These functions are: Pre-charge Level
(P4-01) and Thrust Bearing Frequency (P4-05). Refer to the Thrust Bearing Frequency (P4-05) for further description about the thrust
bearing function. There are two pre-charge operation methods: (1) Pre-charge with Thrust Bearing function disabled. (2) Precharge and
Thrust Bearing functions both enabled.
Some pump systems require the system to be “pre-charged” before normal operation can occur. The built-in pre-charge function allows
the pump system to run at a fixed motor speed for a programmed time. This function also operates in conjunction with a programmable
feedback level and/or an external contact to indicate that the desired level has been reached.
Pre-charge with Thrust Bearing Function Disabled.
The pre-charge level that the iQpump drive will operate at is determined by programming the Pre-charge Level (P4-01). The drive will
monitor the Feedback Level (U1-91) and compare the feedback level with the level programmed in the Pre-charge Level (P4-01). When
the feedback level reaches the Pre-charge Level (P4-01), the drive will disable the pre-charge mode and switch to Auto Mode or
automatic regulation.
The frequency reference used during the pre-charge mode is determined by programming Pre-charge Frequency (P4-02) for a maximum
allowable time set in the Pre-charge Time (P4-03).
A multi-function digital input can be programmed to indicate the pre-charge has been completed, “Low Water Level” (H1-xx = 85), with
Low Water Input (P1-15) determining if the low water detection is a normally-open or normally-closed contact.
The pre-charge can also be disabled by programming the multi-function digital input for Pre-charge Disabled (H1-xx = 84).
The pre-charge is only active in Auto Mode. The Pre-charge Level (P4-01) works in conjunction with the Pre-charge Frequency (P4-02)
and the Pre-charge Time (P4-03). The units for this parameter are determined by the System Units (P1-02).
Note: The drive will stop when one of the following conditions occur:
• The feedback level rises above the Pre-charge Level (P4-01)
• The Pre-charge Time (P4-03) elapses, or
• The Low Water Level input (H1-xx = 85) is deactivated
If P1-01 = 3, the function is active when there is only one drive running on the network. <0034>
The acceleration time used during pre-charge mode is determined by Acceleration Time 1 (C1-01).
If the Pre-charge Frequency (P4-02) is less than the Minimum Pump Frequency (P1-06), the drive will internally use a Pre-charge
Frequency equal to the Minimum Pump Frequency (P1-06) value.
The pre-charge function can only be activated while the drive is in “stop” condition. To enable the pre-charge function requires the
Pre-charge Time (P4-03) to be set to a value greater than 0. When the pre-charge function is activated, a “Pre-charge” alarm will be
displayed on the digital operator.

Pre-charge with Thrust Bearing Function Both Enabled. <0032>
When both Pre-charge and Thrust Bearing modes are enabled, the system will function as follows: Upon receiving a run command, the
drive will ramp up to the Thrust Bearing Frequency (P4-05) using the Thrust Bearing Acceleration Time (P4-04). After reaching the
Thrust Bearing Frequency (P4-05), the Pre-charge becomes active and P4-05 becomes the new minimum frequency. The drive will ramp
up to the Pre-charge Frequency (P4-02) and will remain at this frequency until the Pre-charge has been completed. This can occur when
the P4-03 time has expired, P4-01 level has been reached, or the Low Water digital input has been deactivated.
If the drive is to stop at any time after the Thrust Bearing Frequency has been reached, the drive will ramp down to the P4-05 frequency
at the rate programmed in Deceleration Time (C1-02). This condition can occur due to loss of run command, auto mode, or drive is in the
sleep mode. The drive will then ramp down from a frequency (P4-05) to 0 using Deceleration Time programmed in P4-06. The Thrust
Bearing Acceleration is active when working from sleep while the Pre-charge is not.
The Pre-charge Frequency (P4-02) should be set to a value greater than the Thrust Bearing Frequency (P4-05). If the Pre-charge
Frequency (P4-02) is less than the Thrust Bearing Frequency (P4-05), the drive will internally use a Pre-charge Frequency equal to the
P4-05 value.
If the Pre-charge Frequency (P4-02) is less than the Minimum Pump Frequency (P1-06), the drive will internally use a Pre-charge
Frequency equal to the Minimum Pump Frequency (P1-06) value.

CAUTION
The following procedures are necessary for proper protection and setup of a submersible pump, for example
Franklin Electric Submersible Pumps.
The Franklin Electric Submersible Pump (motor) requires an acceleration and deceleration time of one second when
accelerating up from 0 - 30 Hz, or decelerating down from 30 - 0 Hz. The frequency reference of 30 Hz is the minimum
allowable speed of the Franklin Electric motors. Please verify that the pump (motor) running at 30 Hz does not produce

WARNING
When the drive is powered down while running, and upon the return of power, the drive will automatically
initiate an internal “Run” command. Take extreme caution when using this function.
• Make sure it is safe to use this function in combination with the application requirements.
• This function is the sole responsibility of the user when activated (enabled) and the user accepts application liability.
This “Run” status can be stored when operating from the digital operator (b1-02 = 0) and in the Auto Mode. To enable this function,
program the Auto Mode Operator Run Power Down Storage (P4-10) to a value of 1.
The primary use of this function is to automatically restart the pump system after a long period of power loss.
This function does not work if the system is left in the Hand Mode and power is removed.
в—† P4-11 Utility Start Delay <0034>
Setting Range:
0.0 ~ 1000.0 min
Factory Default: 0.2 min
This sets the amount of time the drive will delay starting if a run command is present at the time of power up. A setting of 0.0 disables this
function.
Function Description <0034>
Utility Start Delay. The Utility Start Delay function is enabled when parameter P4-11 is set to a value greater than zero. When a run
command is present within 1 second of power being applied to the drive, such as, if parameter P4-10 is set to “1”, or the run command is
jumpered on the terminal strip, the drive will delay running for the time specified in parameter P4-11. At the same time, the message will
be shown on the LCD operator “Utility Delay”.
If the run command is removed then re-applied during the P4-11 time, the drive will cancel the utility start delay and start running right
away.
The Utility Start Delay will also be applied when the drive is auto-restarting after an Undervoltage (UV) or Overvoltage (OV) fault.
If the Start level (P1-04) is enabled, the drive will delay the P4-11 time plus the P1-05 time.

в– Function Description: <0034>
Two Motor Alternation Disabled (P4-14 = 0): When parameter P4-14 = 0, the 2-motor alternation function is disabled. All timers
associated with the 2-motor alternation function will be cleared. The digital output (H2-0x = 43) will be de-energized.
Two Motor Alternation Enabled (P4-14 = 1): When parameter P4-14 = 1, the 2-motor alternation function will be enabled. The drive
will first hold the “Mot 2 Alternate” digital output (H2-0x = 43) de-energized, which forces the relay / contactor logic to connect the first
motor to the drive's output terminals.
Any time the drive is putting power to the motor (running, non-zero speed, not base-blocked), the alternation timer will run. When the
timer reaches the time entered into the Alternation Time (P4-16) parameter, the drive will then switch over to the second motor,
depending on the setting of parameter P4-15. If P4-15 is set to “Wait For Stop” (P4-15 = 0), the drive will continue to operate on motor
1 until the drive would normally go to zero speed (zero reference, sleep mode, remove run command, fault). Once the drive comes to a
stop, the “Mot 2 Alternate” digital output (H2-0x = 43) will energize, so that when the drive restarts it will be running on motor 2.
If P4-15 is set to “Immediate” (P4-15 = 1) and the drive is operating in “Auto” mode when the alternation timer reaches the P4-16 level,
the drive will immediately stop using the selected stopping method (b1-03). Once the drive comes to a stop, the “Mot 2 Alternate” digital
output (H2-0x = 43) will energize, and the drive will restart and ramp back to speed after the minimum base-block time. However, if the
drive is operating in the “Hand” mode and the alternation timer reaches the P4-16 level, the drive will respond as if P4-15 is set to “Wait
For Stop”.
Once the digital output is switched so that motor 2 is being driven, the alternation timer re-starts. When enough time passes with the drive
running that the alternation timer reaches the P4-16 level, the drive will switch back to motor 1 similar to above, depending on the P4-15
setting.
The alternation timer and motor selection are stored to EEPROM once per hour. Whenever parameter P4-14 is changed, the internal
alternation timer and the alternation time stored in EEPROM are cleared.
P4-14 special considerations:
• When P4-14 is changed from 0 => 1 - Motor 1 will be used first.
• When P4-14 is changed from 2 => 1 - Motor 2will be used first.
• When P4-14 is changed from 3=> 1 - Motor 1 will be used first.

timers associated with the 2-motor alternation function will be cleared. The digital output (H2-0x = 43) will be de-energized.
Motor 2 Only (P4-14 = 3): When parameter P4-14 is set to “Motor 2 Only” (P4-14 = 3), the 2-motor alternation function is disabled. All
timers associated with the 2-motor alternation function will be cleared. The digital output (H2-0x = 43) will be held energized at all

в—† P4-23 Lube Pump Delay Timer <0034>
Setting Range:
0.0 ~ 300.0 s
Factory Default: 0.0
The Lube Pump Delay Timer parameter provides a digital output to trigger a lube pump or valve prior to starting the motor.
Whenever the drive is supposed to start turning the motor, the “Lube Pump” digital output will energize for a set amount of time before
the drive actually starts. This will allow a small lubrication pump or valve to pre-lubricate the pump seals prior to the main pump
starting.
If the drive is running but base-blocked via the multi-function digital inputs (H1-0x = 8 or 9), the lube pump output will not energize
when the base-block is released.
в– Function Description: <0034>
Lube Pump: The Lube Pump function will operate anytime the drive is going to accelerate from zero speed. Instead of starting, the drive
will remain base-blocked at zero speed until the lube pump timer expires. The lube pump timer is configured by parameter P4-23. If
parameter P4-23 is set to zero then the lube pump feature is disabled. Whenever the lube pump timer is timing (after a start or re-start),
the Lube Pump digital output (H2-0x = 55) will be energized. This digital output is meant to connect to a small lubrication pump or
solenoid valve that will lubricate the main pump bearings.
If an Anti-Jam is detected, the Lube Pump will NOT activate between Anti-Jam retries.

Description
Analog Input A1 (0~10 V)
Hand Reference (P5-02) (factory default)
The iQpump drive can be operated manually or in the “Hand” mode. The frequency for the hand mode can be an analog input (0 ~ 10
Vdc) or from the digital operator (P5-02).
The hand mode operation is useful when testing the system during initial start-up without the automated regulation functions of the
iQpump drive.
The selection to determine the hand mode reference is determined by programming the Hand Mode Reference Source (P5-01). If P5-01 =
1, then the hand reference frequency is set by programming the Hand Reference (P5-02).
The Hand Mode Reference Source (P5-01) works in conjunction with the Hand Reference (P5-02) if P5-01 = 1.
The Hand Mode can be activated from the digital operator or by programming a multi-function digital input for “Hand Mode” (H1-xx =
80).
To change the hand reference requires the P5-02 parameter to be programmed also. U1-01 will be the only monitor available and the Up /
Down arrow keys will not operate like a digital MOP.

в—† P5-02 Hand Reference
Setting Range:

Factory Default: 40.00 Hz
The iQpump drive can be operated manually or in the “Hand” mode. The frequency reference for the hand mode is programmed in the
Hand Reference (P5-02).
The Hand Reference (P5-02) is used when the hand mode is active and the Hand Mode Reference Source (P5-01) is set to 1.
Refer to Hand Mode Reference Source (P5-01) for more details.
The Hand Reference (P5-02) works in conjunction with the Hand Mode Reference Source (P5-01). Allow the “Hand Mode” reference to
operate the same as a digital preset reference (d1-0x) so that it can be set from the “U1-01” menu. Although P5-02 will act as a normal
“d1-xx” frequency reference, it will not be affected by P1-02 / P1-03. The Operator MOP feature will NOT work with the Hand
Reference parameter.
If the thrust bearing function is enabled, P4-05 determines the minimum Hand Reference allowed.

•
Flow rate monitoring (digital operator)
Accumulation of flow over time (volume), stored in EEPROM
Additional method to activate the sleep function
Additional method to detect a “No Flow” condition
Uses Terminal A1
в– Function Description: <0034>
Flow Rate: A voltage (current) from a flow meter, which is installed in the pump discharge stream, is connected into terminals A1 and
AC. Terminal A1 will act as a “flow” input only when it isn’t being used as a frequency reference (b1-02 = 1). Parameter P6-01 will then
allow the drive to calculate flow rate from the voltage on Terminal A1. The flow rate will then be scaled and displayed on monitor U1-95.
Units scaling for monitor U1-95 will be determined by parameter P6-02.
Volume Accumulated: The flow data obtained from Terminals A1 and AC, will be integrated over time in order to calculate total fluid
volume. The fluid volume will be displayed in two monitors, U1-96 and U1-97. Parameter P6-03 will reset the volume accumulated data
and return the monitors U1-96 and U1-97 to zero. The maximum value that can be displayed on U1-96 is 65535. The maximum value
that can be displayed on U1-97 is 61036. An internal register tracking volume accumulated has a maximum range of 4 billion
(4,000,000,000) gallons. Accumulated volume will be stored with a resolution of 4 gallons. Accumulated volume will remain at its
maximum value until it is reset, it will not “rollover”.
Note: The accumulated volume will NOT be reset if the drive is initialized (A1-03 = 2220 or 3330).
Figure 1.161
How to calculate accumulated flow from the information in monitors U1-96
and U1-97
Step 1: Take the value in monitor U1-97 and multiply by the number 65535.
Step 2: Take the result from step 1 and add it to the value in monitor U1-96.
Example:
U1-96 = 51079
U1-97 = 228
Step 1: 228 x 65,535 = 14,941,980
Step 2: 14,941,980 + 51,079 = 14,993,059
Total accumulated flow = 14,993,059 gallons

Low Flow Alarm: The flow data obtained from Terminals A1 and AC, will be monitored for a “low flow” condition. If the flow rate
drops below a level set by parameter P6-04, for more than the time specified by P6-05, the drive will display a “LOWFL - Low Flow”
Alarm. The run command must be removed, or the flow rate must remain above the P6-04 for one second to clear the “LOWFL - Low
Flow” Alarm. The Low Flow Alarm is disabled when: the drive is not running, the drive is faulted, or when the frequency reference /
output frequency is at zero Hz. Once the drive starts running, the Low Flow start timer P6-06 time needs to elapse before the Low Flow
Alarm is detected. The Low Flow Alarm is only active when P6-07 = 1.
Low Flow Fault: The flow data obtained from Terminals A1 and AC, will be monitored for a “low flow” condition. If the flow rate drops
below a level set by parameter P6-04, for more than the time specified by P6-05, the drive will fault out on a “LOWFL - Low Flow” Fault
and coast to stop. The Low Flow Fault is disabled when: the drive is not running, the drive is faulted, or when the frequency reference /
output frequency is at zero Hz. Once the drive starts running, the Low Flow start timer P6-06 time needs to elapse before the Low Flow
Fault is detected. The Low Flow Fault is only active when P6-07 = 2 or 3. If P6-07, the Low Flow Fault will NOT be auto-restarted.
YASKAWA TM.iQp.07 iQpump Controller Programming Manual
211
Low Flow Fault Auto Restart: When parameter P6-07 = 3, the Low Flow Fault will be auto-restarted. It will use the time set in
parameter P6-08 before attempting another restart instead of the normal auto-restart time, L5-03. In order for this feature to work, L5-01
needs to be set to a value greater than zero.
Accumulated Level Output / Alarm / Fault: A total amount of water can be entered into parameters P6-09 and P6-10. When the
amount of water measured using A1 exceeds this amount, the drive will set the “Accum Level” digital output. If parameter P6-11 is set to
“1”, an Accumulated Level Alarm will display and the drive will keep running. If parameter P6-11 is set to “2”, an Accumulated Level
Fault will occur and the drive will coast to a stop.
Figure 1.162
How to calculatethe Accumulated Parameters P6-09 and P6-10
Step 1: Take the desired accumulated level and divide it by the number 65,535.
Step 2: Take the result of Step 1 and drop everything to the right of the decimal
place. This would leave just the whole number, and that should be
entered into parameter P6-10.
Step 3: Take the value you entered into P6-10 and multiply it by 65535. Subtract
this value from the desired accumulated leve. This is the number that
should be entered into parameter P6-09.
Desired accumulated level: 12,345,678
Step 1: 12,345,678 / 65,535 = 188.38297
Step 2: 188,38297 = 188
Set P6-10 = 188
Step 3: 12,345,678 - (188 x 65,535 = 25,098
Set P6-09 = 25098

Sleep Function Using the Flow Meter: The Sleep function can be triggered by the Flow Meter. To enable this feature, the sleep level
type to be set to “FlowMtr-Term A1” (P2-01 = 4). Also the Flow Meter needs to be enabled by setting a non-zero value into P6-01.
The drive’s output needs to be active (faster than zero speed) for the time specified in parameter P6-06 before a sleep condition can be
detected. The flow will then have to drop below the P2-02 level for more than the P2-03 Sleep Delay Time for the drive to go to sleep.

Description

Basic Concepts:
Anti-Jam: The drive will monitor output current when starting from zero speed. If the current goes too high, it will coast to a stop then
switch into reverse. The drive will then repeat this cycle until the output current remains below the detection level, or until it faults out on
an “AJF - Anti-Jam Fault”.
De-Scale: The drive will monitor the number of operating hours of the motor. After a set amount of operating time, the drive will go into
the De-Scale function the next time the drive is started, either in hand or auto mode. This function will run the drive forward, then reverse
for a specified number of times before normal operation will automatically resume.
Anti-Jam and De-Scale are only effective when P1-01 = 0.
Function Description: <0034>
в– Anti-Jam Function: The Anti-Jam function will only operate when all of the following conditions are met:
• P7-01 = 1 Anti-Jam is enabled
• P1-01 = 0 Simplex Operation Only
It will keep monitoring the output current for the time specified by parameter P7-11.
If the drive’s output current goes above the value set in the Anti-Jam Detection Current Level (P7-03), or the drive goes into current limit
for more than the time set in the Anti-Jam Detection Time parameter (P7-04), the “Anti-Jam / De-Scale” alarm will display and the drive
will coast to a stop. After the time set into the Momentary Power Loss Minimum Base Block Time parameter (L2-03) expires, the drive
will attempt to run in reverse at the Anti-Jam / De-Scale Frequency Reference (P7-05). If the current again exceeds the Anti-Jam
Detection Current Level (P7-03) level for more than the time set in Anti-Jam Detection Time (P7-04), the drive will again coast to a stop
and the internal cycle counter will be incremented. This process will then repeat. During this time the integrator of the PI controller will
be held and not allowed to wind-up.
If the internal cycle counter reaches the value set into the Anti-Jam / De-Scale Cycle Count parameter (P7-02), the drive will then faultout on an “AJF - Anti-Jam Fault”.
If during the Anti-Jam function the motor current drops below the level set in Anti-Jam Detection Current Level (P7-03) for more than
the time set in Anti-Jam Detection Time parameter (P7-04), the drive will then operate normally. The “Anti-Jam / De-Scale” alarm will
clear, the PI controller will be released and the internal cycle counter will be reset.
De-Scale Function: The De-Scale function will only be allowed to operate when all of the following conditions are met:
•
•
•
•
•

While the pump is running (Auto or Hand mode), an internal run timer is activated. This timer is stored in EEPROM at power-down. If
the amount of time accumulated in the timer is less than the De-Scale Pump Run Time parameter (P7-10), the drive starts normally. When
220
YASKAWA TM.iQp.07 iQpump Controller Programming Manual
the timer is equal to or greater than the De-Scale Pump Run Time parameter (P7-10) value, the drive will automatically perform the DeScale Function the next time the drive comes out of zero speed in the “Auto” mode.
For the whole time the drive is executing the De-Scale function, the “De-Scale Active” alarm will flash on the display. The drive will first
accelerate using the De-Scale Acceleration Time (P7-08) time. It will then decelerate using the De-Scale Deceleration Time (P7-09).
Once the drive reaches zero speed, it will immediately repeat the cycle for as many times as specified by the Anti-Jam / De-Scale Cycle
Count (P7-02) parameter.
During the De-Scale Function, many iQpump features are disabled: Thrust Bearing, PI control, Pre-charge, Low Feedback fault and Not
Maintaining Setpoint fault. The other protective functions, however, will remain active.
If the De-Scale function is interrupted by a fault or by removing the run command, all timers associated with the De-Scale function will
be reset.
The “Not Maintaining Setpoint”, “Loss Of Prime”, and “Low Feedback” faults will be disabled while the drive is performing the DeScale operation.
The De-Scale run timer will be stored to EEPROM when:
•
•
•
•
Once per hour that the drive is running
Right after a successful De-Scale Cycle (timer set to zero then stored to EEPROM)
If the run command is removed during a De-Scale Cycle (timer set to zero then stored to EEPROM)
If a fault occurs during the De-Scale Cycle (timer set to zero then stored to EEPROM)
Forced De-Scale Operation: When parameter P7-01 = 3 (Forced De-Scale), the drive will perform a De-Scale every time it starts. This
mode is intended to be used during the setup of the De-Scale function only. The internal De-Scale run timer is forced to zero (reset) when
the drive is in this mode.

в– Overview
This parameter will allow the drive to control pressure when there is adequate water inside of the well. When the well level drops to the
Water Level Setpoint (P8-03), it will regulate the well level and the pressure will be allowed to drop. The drive will also go to sleep, wake
up, and / or alarm / fault based on well water level.

YASKAWA TM.iQp.07 iQpump Controller Programming Manual
в– Basic Concept
When this feature is enabled, the drive will still use the standard iQpump PI controller to control pressure. If the water in the well drops to
the Water Level Setpoint (P8-03), the drive will seamlessly switch over and control water level instead using an additional PI controller.
Under most circumstances this will cause a reduction in flow rate and pressure, as the drive is then attempting to match the output of the
pump to the rate that water is recharging the well. If the pressure returns to the pressure Setpoint at any time, the drive will seamlessly
switch back to controlling pressure.
If the well level drops below the Minimum Water Level (P8-04) for more than the Sleep Delay Time (P2-03), the drive will go to sleep.
The drive will resume operation when the level in the well goes above the Wake-Up Level (P8-05) for more than the Start Level Delay
Time (P1-05).
There is a water level detection feature as well. If the water level drops below the Low Level Detection Level (P8-07) for more than the
Low Level Detection Time (P8-08), the drive will respond depending on the setting of the Low Level Behavior (P8-09) parameter. This
feature is also active in “Hand” mode.
The drive will NOT perform a sleep boost if it is being forced to sleep based on the water level.
в– Function Description <0034>
Enabling Level Control Features
The level control features, pressure and level control plus Low Level Detection can be enabled by setting parameter P8-01 to 1 (Enabled).
The drive will only perform the pressure and level control when “normal” PI mode is enabled
(b5-01 > 0, not jogging, not disabled via MFDI, etc.), and drive is not in a multiplex mode (P1-01 > 0).
Sensing Water Level
Terminal A1 will act as the water level analog input. An analog pressure sensor, mounted down in the well at the pump will provide the
required signal. Parameter P8-02 should be set to the full-scale pressure of the transducer. The drive will then convert the reported
pressure into an amount of water above the pump. (2.308966 ft / psi) This level will be displayed on the U1-98 monitor.
Wire break will be detected on Terminal A1 when:
•
•
•
•
PI Feedback Loss Detection is enabled (b5-12 = 1 or 2)
Pressure and Level control is enabled (P8-01 = 1)
PI is NOT disabled via Multi-Function Digital Input
Signal on Terminal A1 goes below -6.25% or above 106.25% for more than 1 second
Note: Wire-break detection on Terminal A1 occurs after the gain / bias parameters (H3-02 and H3-03) are applied.
The drive will then react depending on how parameter b5-12 is programmed.
Note: To convert Terminal A1 to 4-20 mA signal, connect a 250 Ohm precision resistor (1/4 Watt or greater) between A1 and
AC. Then program H3-02 = 231.2% and H3-03 = 25.0%.
Pressure and Level Control
When there is adequate water available in the well, the drive will regulate pressure using virtually all of the standard iQpump features,
including but not limited to: sleep, sleep boost, minimum pump speed, thrust bearing, pre-charge, utility delay, etc.
The drive can respond in one of two ways to a drop in water level inside of the well. If the Water Level Setpoint (P8-03) is programmed
to a value greater than the Minimum Water Level (P8-04), the drive will attempt to regulate the water level in the well to the P8-03 level.
As the water level approaches the P8-03 level, the drive will slow down which will cause pressure and flow will also decrease. The drive
will then regulate output speed in order to maintain the level in the well. The response of the drive when regulating level can be adjusted
using parameters P8-10 and P8-11. However, if the level in the well drops below the Minimum Water Level (P8-04), for more than the
Sleep Delay Time (P2-03), the drive will go to sleep. When the water recharges the well to above the P8-05 level for more than the P1-05
time, normal operation (pressure regulation) will resume.
Note: The Level Control Minimum Speed parameter (P8-06) should be set to a high enough value to insure flow.
The other way that the drive can respond is to try and maintain the pressure setpoint, then go to sleep immediately based on water level.
This can be accomplished by programming the Water Level Setpoint (P8-03) to a value less than the Minimum Water Level (P8-04).
When the level in the well drops below the Minimum Water Level (P8-04), for more than the Sleep Delay Time (P2-03), the drive will go
to sleep. When the water recharges the well to above the P8-05 level for more than the P1-05 time, normal operation (pressure regulation)
will resume.
Sleep and Wake-Up Methods
The drive will go to sleep in one of two ways. As described above, if the actual water level drops below the Minimum Water Level (P804) for more than the Sleep Delay Time (P2-03), the drive will go to sleep without performing a sleep boost. The drive can also go to
YASKAWA TM.iQp.07 iQpump Controller Programming Manual
227
sleep based upon the standard sleep settings, controlled by parameters P2-01 and P2-02. If the drive goes to sleep due to P2-01 and P2-02,
a sleep boost will be performed.
When the level control is enabled (P8-01 = 1), the drive will only wake up (or start) once the water level goes above the wake-up level
(P8-05) AND the standard sleep function calls for a wake-up (set by parameters P1-04 and P1-05.
Low Level Detection
Independent of the pressure and level control is a low level detection feature. This feature is active all of the time, when running, when
not running, and in “Hand” mode. If the level in the well drops below the Low Level Detection Level (P8-07), for more than the Low
Level Detection Delay Time (P8-08), the drive will respond according to the Low Level Behavior (P8-09) parameter. The Low Water
Level digital output (H2-0x = 57) will activate anytime the level in the well drops below the Low Level Detection Level (P8-07), for more
than the Low Level Detection Delay Time (P8-08), or the drive is faulted on a LOWWL - Low Water Level fault.

This parameter has the ability to run the iQpump MEMOBUS/Modbus Network with just one drive connected to a PI Feedback Source
and automatically switch from the Analog Feedback Source to the Network PI Feedback Source in case of transducer or wire breaks.
The drive Analog PI feedback signal and status is sent to the iQpump MEMOBUS/Modbus network. The status is dependent on the
regular PI Feedback Loss (b5-13 and b5-14) that is run in the background per drive. If the status is good and the drive is the current Lead
drive, that feedback signal is then used as the Network PI Feedback and will be constantly sent to all the drives in the network. If the
current Lead drive does not have a good status, then the Network PI Feedback is taken from another drive which has a good status.
When there is no Analog Feedback signal for PI Feedback, then the drive will use the Network PI Feedback register if it's allowed (see
P9-02 modes) and flash an alarm if desired.
When P1-01 = 3 and P9-02 = 1 or 2, parameter b5-12 will only do the specified action when the Network Feedback signal is lost (will
happen when none of the drives in the system has a valid PI feedback signal).
в– Function Description: <0034>
When P1-01 = 3 and b5-12 > 0, the analog feedback detection process is started automatically for all drives on the network that has
P9-02 в‰ 3 as soon as one of the drive gets a run command and is not running in pre-charge mode. When using the same parameters on a
4-20mA feedback source (H3-08 = 2 and H3-09 = B), the analog feedback detection process is always active. Drives that fail on the
feedback detection will indicate that their feedback signals are invalid and will not be considered by the iQpump MEMOBUS/Modbus
Network as good sources. The network in turn will read out the valid signals, select using lead-drive priority, and send it back to all the
drives as the Network PI Feedback. If the current lead drive has a valid analog feedback signal, then it will be the Network PI Feedback
signal. Otherwise, the Network PI Feedback signal is set to a drive with a good analog signal based on the Drive Discovery of the iQpump
MEMOBUS/Modbus Network. In both cases, a status bit is also sent out indicating that the network has a good feedback source.
When P9-02 = 0 (Analog Only), the drive will never read the Network PI Feedback register as the feedback source, even though the drive
will still transmit its own PI Feedback signal to the network. The feedback detection is based solely on parameter b5-12.
When P9-02 = 1 (Ana => Net, No Alrm), the drive will read the Network PI Feedback register if the analog feedback detection
determines a signal loss. If the network Feedback signal is invalid as well, it will act according to b5-12 (= 1 or 2). Note that setting b5-12
= 0 and H3-09 = B will disable analog feedback detection and will prevent the drive from switching to the Network PI Feedback.
When P9-02 = 2 (Ana => Net, Alarm), the drive will read the Network PI Feedback register if the analog feedback detection determines
a signal loss. In addition, an alarm will be displayed indicating that the analog has been lost, and that the feedback source is now the
network. If the network Feedback signal is invalid as well, it will act according to b5-12 (= 1 or 2). Note that settings b5-12 = 0 and
H3-09 = B will disable analog feedback detection and will prevent the drive from switching to the Network PI Feedback.
When P9-02 = 3 (Network Only), the drive will always read the Network PI Feedback register. If the network feedback signal is invalid,
it will act according to b5-12 with the following differences:
• b5-12 = 1: Instead of alarm, NetwrkFB Lost message
• b5-12 = 2: Instead of fault, NetwrkFB Lost message, drive will not accept iQpump Network run commands, and coasts-to-stop
Note: Any drive with b5-12 = 0, H3-09 = B, and P9-02 в‰ 3 will effectively have no feedback loss detection (unless Wire Break
detection is used) and will continuously send the Analog PI Feedback to the iQpump Network regardless of whether it is
a healthy signal or not.

This parameter minimizes uneven run-times in a multi-pump system.
The First Drive is defined as the first pump that was run in the system (see MEMOBUS / Modbus Multiplex Diagrams 1 and 2: Run Order
/ Pump #). The Last Drive is defined as the Lead Drive.
Alternation can be requested by a drive when a specified time has expired. Two basic modes allow the timer to either run from the lead
drive (LIFO - Last In, First Out), or from the first drive (FIFO - First In, First Out). When the timer expires, the drive is removed from the
system and consequently turned-off, and a new lead drive is brought online to replace it. In FIFO, another mode (FIFO Auto) gives
control to the Multiplex system on bringing the new lead drive online.
Since the iQpump MEMOBUS / Modbus Network uses monitor U1-13 when P9-01 = 1 (Lowest Runtime), lead drive selection is thus
directly affected by o2-07 and o2-08. It is recommended to keep o2-08 = 1 (Running Time). It should be noted that when U1-13 goes past
65535 hours, it gets reset to zero.
в– Function Description: <0034>
When the Alternation Time P9-03 (with unit based on P9-19) is not set to 0, the Alternation feature is enabled, and is based on the P9-04
(Alternation Mode) parameter. In FIFO, the timer is run on the first drive while in LIFO it is on the lead drive. When the timer expires, the
drive requests alternation based on the P9-04 setting and sends that information to the MEMOBUS / Modbus network.
Setting P9-04 to “0: FIFO Auto” will remove the first drive in the running queue and will start the lead drive automatically (if needed)
using the MEMOBUS / Modbus Multiplex function. If there is only one drive running, then the new lead drive is forced to run since the
MEMOBUS / Modbus Multiplex function can not run if there is no lead drive.
Setting P9-04 to “1: FIFO Forced” will remove the first drive in the running queue and will force a new lead drive to run.
Setting P9-04 to “2: LIFO” will remove the current lead drive and replace it with a new lead drive.
YASKAWA TM.iQp.07 iQpump Controller Programming Manual

Setting P9-04 to “3: FIFO @ Sleep” acts the same as P9-04 =1 except alternation is only requested when the drive is in Sleep Mode.
The new lead drive is selected using parameter P9-01.

YASKAWA TM.iQp.07 iQpump Controller Programming Manual
в—† iQpump MEMOBUS / Modbus Multiplex
в– MEMOBUS / Modbus Multiplex
In order to run and control networked pumps, multiplexing needs to be implemented
After the iQpump memobus network is established, it will continually look for a drive that is ready to run (has Auto mode run, and not
faulted). It will command that drive to run in PI (thus becoming the lead drive) so that it can regulate the system pressure. When the
pressure is too low that it can no longer be maintained, the lead drive will attempt to pass the lead responsibility either to the next
available or to drive with the lowest runtime. The previous lead drive becomes a lag drive and will run at either PI regulation or a set
frequency thus making the new lead drive regulate the system pressure. This process is referred to as staging.
If the system pressure gets too high that a drive needs to shut down (unless it's the only drive left), the lead drive will attempt to shut off
and pass the lead responsibility back to the previous drive. This process is referred to as de-staging.
The selection of the new lead drive depends on the setting of a new parameter, P9-01 (Lead Drive Selection). When P9-01 = 0, the next
lead drive will be the next drive that the iQpump MEMOBUS / Modbus network has detected during its drive discovery scan. When P901 = 1, the next lead drive will be the drive with the lowest run-time based on U1-13 (affected by o2-07 and o2-08).
Since the iQpump MEMOBUS / Modbus network uses monitor U1-13 when P9-01 = 1 (Lowest Runtime), lead drive selection is thus
directly affected by o2-07 and o2-08. It is recommended to keep o2-08 = 1 (Running Time). It should be noted that when U1-13 goes past
65535 hours, it gets reset to zero.
в– Function Description: <0034>
When P1-01 = 3 (Pump Mode = MEMOBUS / Modbus Network), issuing an Auto mode run will add it to the list of networked drives
that are available to run. At system start-up, the iQpump MEMOBUS / Modbus network will look for a drive available to run based on
parameter P9-01 (Lead Drive Selection). If there's an available drive, it will send a network command to run it as a lead drive (running in
PI). When P9-29 Net Start Delay is greater than 0.0s and the system is stopped, the system will wait the P9-29 setting after the first Auto
mode drive has been detected. This will allow other drives to be put on Auto mode and be considered for lead selection. All the drives in
the system will show a Net Start Dly message when the timer is still counting.
The P9-01 parameter is always used when there is a network request to stage.
A setting of “0: Next Available”, will look for the next drive ready-to-run in the network queue which is based on when the drive was
detected in the network. If the search reaches the end of the queue without finding a suitable drive, it will loop around to the first detected
drive. Figure 182. shows an example of how the lead-lag operation will work for this setting.
A setting of “1: Lowest Runtime” will look for the drive that is ready-to-run on the network that has the lowest runtime (based on
monitor U1-13, which is affected by parameters o2-07 and o2-08). Figure 187. shows an example of how the lead-lag operation will work
for this setting.
Parameter P9-05 (Lag Drive Mode) defines how lag drives function: running in either PI regulation or fixed speed. If P9-05 = 0, anytime
the drive shifts from being a lead to a lag, the drive will hold the current speed for the time set in P9-07 and then force it to the P9-06
level. If P9-05 = 1, the lag drive will continue to regulate its speed based on the PI conditions. This setting is not commonly used and
could result in an unstable system if not properly adjusted. If P9-05 = 2, the drive will turn off when the drive shifts from being a lead to
a lag and becomes available for the system to run as a lead again.
The lead drive uses parameters P9-08 to P9-11 to determine if it needs to stage, and parameters P9-12 to P9-15 to determine if it needs to
de-stage. Staging will request for a new lead drive and make the current one a lag drive. A stage request is only made when there are
drives available to run and the number of drives running is below P9-23. De-staging will make the previous lead drive (which is now a lag
drive) a lead drive once again, and stops the current lead drive. A de-stage request is only made when there are 2 or more drives running.
With this setup, there can only be 1 lead drive on the network at any given time. A quick de-stage function is invoked when high feedback
(based on P1-09 and P9-18) is detected for 2 seconds.
Staging:
P9-08 = 0: Output Frequency:
This mode monitors the lead drive output frequency and determines if staging is needed to maintain the setpoint. If the output frequency
of the lead drive rises above the P9-09 level for the time set in P9-11, the drive will issue a network stage request if there is a drive
available to run. Refer to Figure 184.
P9-08 = 1: Feedback Level:
This mode monitors the feedback level and determines if staging is needed. If the difference in setpoint and feedback (setpoint feedback) has exceeded the P9-10 level for the time set in P9-11, the lead drive will issue a network stage request if there is a drive
available to run. Refer to Figure 185.
YASKAWA TM.iQp.07 iQpump Controller Programming Manual
243
P9-08 = 2: Feedback + Output Frequency:
This mode monitors both the feedback level and the output frequency to determine if staging is needed. When the output frequency rises
above the P9-09 level and the delta feedback (setpoint - feedback) has exceeded the level set in P9-10 for the time set in P9-11, the lead
drive will issue a network stage request if there is a drive available to run. Refer to Figure 186.
De-staging:
P9-12 = 0: Output Frequency:
This mode monitors the lead drive output frequency and determines if de-staging is needed to maintain the setpoint. If the output
frequency of the lead drive drops below the P9-13 level for the time set in P9-15, then a de-stage request is issued if this is not the only
drive running. Refer to Figure 187.
P9-12 = 1: Feedback Level:
This mode monitors the feedback level and determines if de-staging is needed. If the difference in feedback and setpoint (feedback setpoint) has exceeded the P9-14 level for the time set in P9-15, then a de-stage request is issued if this is not the only drive running.
Refer to Figure 188.
P9-12 = 2: Feedback + Output Frequency:
This mode monitors both the feedback level and the output frequency to determine if de-staging is needed. the output frequency of the
lead drive drops below the P9-13 level and the delta feedback (feedback - setpoint) has exceeded the P9-14 level for the time set in P9-15,
then a de-stage request is issued if this is not the only drive running. Refer to Figure 189.
Quick De-stage (P9-18 x P1-09 < PI Feedback):
If the feedback level goes above P9-18 (set as a percentage of P1-09) for 2 seconds, a de-stage request is issued if this is not the only drive
running. Refer to Figure 190.
If Stabilize Time P9-16 > 0, then whenever a pump becomes a lag drive, or gets de-staged that disables lead-lag control and pump
protection. It will resume these functions when the timer P9-16 expires, which counts only when the drive becomes a lead drive once
again.
Setpoint Modifier P9-17 is used to increase or decrease the setpoint each time an additional pump is brought online to compensate for
system losses or gains. The drive's setpoint is modified using this calculation:
Pump X: Setpoint + ((X-1)(P9-17))
Thus, if there is only one pump running, the setpoint is not modified.
Monitor U1-62 is only available when P1-01 = 3. The monitor displays the drive’s network run queue number. The first drive to run will
show U1-62 = 1, the second drive U1-62 = 2 and so on.
When P1-01 = 3 (MEMOBUS / Modbus Network), the U1-01 Display text will change depending on the Auto Mode run command and
the network run command as can be seen in Table 117 on page 245.

This mode monitors both the feedback level and the output frequency to determine if de-staging is needed. the output frequency of the
lead drive drops below the P9-13 level and the delta feedback (feedback - setpoint) has exceeded the P9-14 level for the time set in
P9-15, then a de-stage request is issued if this is not the only drive running.
в—† iQpump MEMOBUS / Modbus Layered Sequencing and Control
в– MEMOBUS / Modbus Layered Sequencing and Control
Several applications of multiplexed drives require priority sequencing and run restrictions. For example, a drive designated as a back-up
pump would be restricted for alternation only or will have a low run priority. A jockey pump would be designated as a first drive only and
may never be allowed to alternate with a bigger-sized pump. Because of the variety of applications, a flexible set of parameters need to
complement the Multiplex and Alternation parameters.
• Provide more staging control over the MEMOBUS / Modbus Multiplex and Alternation features.
• Ability to restrict drives to first drive only, alternation only or either one.
• Provide a way to return Lead Drive control to a drive with higher priority.
в– Function Description: <0034>
Setting Allow Net Run P9-20 = 0 allows that drive to respond to all network run commands (first drive, stating, alternation). When
P9-20 = 1, the drive is limited to being either the first drive or for alternation. When P9-20 = 2, the drive can only be a first drive. When
P9-20 = 3, the drive is only available for alternation. Note that when Alternation Mode P9-04 = FIFO Auto and there are 2 drives or more
running, the iQpump MEMOBUS / Modbus Network does not actually alternate a drive in. It simply removes the expired first drive and
allows the iQpump MEMOBUS / Modbus Multiplex feature to stage a new drive. Explicit alternation still happens in FIFO Auto when
there is only one drive running at time of alternation.
Setting Run Priority P9-21 the same for all drives on the iQpump MEMOBUS / Modbus Network obviously nullifies the functionality.
Drives will simply use P9-01 at this point to select the next lead drive.
By setting P9-21 differently for a drive on the iQpump MEMOBUS / Modbus Network, sequential lead drive selection can be achieved.
Drives with the same P9-21 level will use the P9-01 parameter to determine the next lead drive.
As a way to give First Drive (and Lead Drive) control back to the drive with the highest priority level P9-21, the Lead Swap @ Sleep
Time P9-24 can be set on the other drives (with a lower priority level) so that if the drive sleeps continuously for the time set, the control
will be passed to the higher priority drive.

•
Start Level: Active on the first pump in the network. Drives that are in the process of Alternation will not undergo this process.
Sleep: Active when the drive is the only drive running on the network.
Over-cycle Protection: Active when the drive is the only drive running on the network.
No-Flow Detection: Active on the lead drive. When No-Flow is confirmed, the lead-drive is de-staged, or if it is the only drive left, it
goes to sleep.
• Pre-charge: Active only on the first drive to run in the network.
• Low City Pressure: Active on any drive in the network. An alarm condition will cause other drives in the network to stop running and
show a “Net Pump Err” message.
• Utility Delay: When this function is active the drive is unavailable to the iQpump MEMOBUS / Modbus Network and will force the
U1-01 text to show “Pump Off Network”.

Auto tuning is recommended to achieve optimum performance. In addition, the iQpump drive requires Line-To-Line Resistance autotuning before it can properly perform the Estimated Speed Search method. This method of speed search allows for bi-directional speed
search. The T1 parameters are found under the Auto-Tuning menu.
To perform auto-tuning follow these steps:
1. T1-02 should be left at the default value (the last 3 digits of the iQpump drive model number).
2. In T1-04, enter the Full Load Amps (FLA) as stamped on the motor’s nameplate.
3. Press the INCREASE key once to display this:
-ATUNEAuto: ATUNE

Press HAND key
4. If ready, press the HAND key once to start auto-tuning. This process will last for approximately 15 seconds. Once auto-tuning is
finished, the digital operator will display this:
-ATUNETune Successful
0 Hz/ 0.00A
5. To exit the Auto-Tuning menu, press the MENU key once.
Note: It is possible to a get a “Data Invalid” error if the either T1-02 or T1-04 fall outside the range of what the iQpump drive
will accept as reasonable levels for the programmed size of the iQpump drive (o2-04).

To use the low water function one of the digital inputs (H1-XX=85)
needs to be programmed. The low water input can be used for a low
water condition or in combination with the pre-charge function to
indicate the reservoir is filled. The low water input fault is only active
during running while operating in auto mode.

Sets the frequency reference used when the thrust bearing function is
active. A value of 0 disables this function.
This deceleration time will be used to bring the drive from Thrust
Frequency (P4-05) to stop when Thrust Mode is active. Any time the
Run Command is removed while the drive is operating in the Thrust
Mode above the Thrust Frequency, this deceleration time will be used
once the frequency reference is at or below the Thrust Frequency.
Note: In Auto Mode, the Minimum Pump Frequency (P1-06) will
become the thrust bearing frequency if smaller than the thrust bearing
frequency in P4-05.
In Hand Mode, the minimum frequency is P4-05 when the thrust
mode is enabled. The Pre-charge level is not active in the hand mode.

Description
System Set-point is incremented with this value depending on the
number of pumps running.
Pump 1: Set-point
Pump X: Set-point + {(X-1) (P9-17)}
Determines the feedback level to trigger a quick de-stage, set as a
percentage of parameter P1-09. The quick de-stage ignores parameters
P9-12 to P9-15 and only uses an internal 2 second delay.
Selects the unit for P9-03
0: Hours (hr)
1: Minutes (min)
Specifies when a network run command is allowed:
0: Always
1: First / Alternation
2: First Only
3: Alternation Only
Sets the Lead Drive selection priority overriding the P9-01 selection. If
multiple drives have the lowest P9-21 value, then P9-01 determines
which drive becomes the Lead.
Determines the number of times the iQpump Memobus Network will
allow automatic restarts of system faults. The drive uses parameter
L5-03 in determining when to attempt a system fault restart.
For proper operation, this parameter should be set the same for all
network drives.
