Selection
Installing a Reactor
Use an AC reactor or DC link choke in the following situations:
• to suppress harmonic current.
• to smooth peak current that results from capacitor switching.
• when the power supply is above 600 kVA.
• when the drive is running from a power supply system with thyristor converters.

Drive Capacity
For specialized motors, make sure that the motor rated current is less than the rated output current for the drive.
When running more than one motor in parallel from a single drive, the capacity of the drive should be larger than [total motor rated current × 1.1].
Starting Torque
The overload rating of the drive determines the starting and accelerating characteristics of the motor. Expect lower running torque than when running the motor from line power. To get more starting torque, use a larger drive or increase both the motor and drive capacity.
Emergency/Fast Stop
During a drive fault condition, a protective circuit is activated and drive output is shut off. The motor may coast to a stop or attempt to decelerate depending on parameter settings. If the emergency/fast stop cannot stop the load as fast as desired, a customer-supplied mechanical brake may be required. Test emergency stop circuitry before putting drive into operation.
n
Repetitive Starting/Stopping
Applications with frequent starts and stops often exceed 150% of their rated current values. Heat stress generated from repetitive high current can shorten the life span of the IGBTs. The expected lifetime for the IGBTs is about 8 million start and stop cycles with a 4 kHz carrier frequency and a 150% peak current.
Yaskawa recommends lowering the carrier frequency, particularly when audible noise is not a concern. The user can also choose to reduce the load, increase the acceleration and deceleration times, or switch to a larger drive. This will help keep peak current levels under 150%. Be sure to check the peak current levels when starting and stopping repeatedly during the initial test run, and make adjustments accordingly.
n
Installation
Enclosure Panels
Keep the drive in a clean environment by installing the drive in an enclosure panel or selecting an installation area free of airborne dust, lint, and oil mist. Be sure to leave the required space between drives to provide for cooling, and take proper measures so the ambient temperature remains within allowable limits and keep flammable materials away from the drive.
Yaskawa offers protective designs for drives that must be used in areas subjected to oil mist and excessive vibration. Contact
Yaskawa or your Yaskawa agent for details.
Installation Direction
NOTICE: Install the drive upright as specified in the manual.
Refer to Mechanical Installation on page 28
installation. Failure to comply may damage the drive due to improper cooling.
n
Settings
Upper Limits
NOTICE: The drive is capable of running the motor up to 400 Hz. Be sure to set the upper limit for the frequency of the drive to prevent the
possible danger of accidentally operating equipment at higher than rated speed. The default setting for the maximum output frequency is
60 Hz.
Lower Limits
NOTICE: Many pumps have a minimum safe operating speed. Be sure to properly set the minimum pump speed in to protect the pump
from damage.
DC Injection Braking
NOTICE: Excessive current during DC Injection Braking and excessive duration of DC Injection Braking can cause motor overheat.
16
YASKAWA TOEP YAIQPM 03B YASKAWA AC Drive - iQpump Micro User Manual
i.2 General Safety
Acceleration/Deceleration Times
Acceleration and deceleration times are affected by the amount of torque generated by the motor, the load torque, and the inertia moment. Set a longer accel/decel time when Stall Prevention is enabled. The accel/decel times are lengthened for as long as the Stall Prevention function is in operation.
n
General Handling
Wiring Check
NOTICE: Do not connect power supply lines to output terminals U/T1, V/T2, or W/T3. Failure to comply will destroy the drive. Be sure to
perform a final check of all sequence wiring and other connections before turning on the power and also check for short circuits on the control terminals, which may damage the drive.
Selecting a Circuit Breaker or Circuit Interrupter
Yaskawa recommends installing a Ground Fault Circuit Interrupter (GFCI) to the power supply side. The GFCI should be designed for use with AC drives (e.g., Type B according to IEC 60755).
Select a Molded Case Circuit Breaker (MCCB) or GFCI with a rated current 1.5 to 2 times higher than the drive rated input current to avoid nuisance trips caused by harmonics in the drive input current.
Magnetic Contactor Installation
NOTICE: To get the full performance life out of the electrolytic capacitors and circuit relays, refrain from switching the drive power supply
off and on more than once every 30 minutes. Frequent use can damage the drive. Use the drive to stop and start the motor.
Inspection and Maintenance
WARNING! Electrical Shock Hazard. Capacitors in the drive do not immediately discharge after shutting off the power. Wait for at least the
amount of time specified on the drive before touching any components after shutting off the power. Failure to comply may cause injury to personnel from electrical shock.
WARNING! Burn Hazard. Because the heatsink can get very hot during operation, take proper precautions to prevent burns. When replacing
the cooling fan, shut off the power and wait at least 15 minutes to be sure that the heatsink has cooled down. Failure to comply may cause burn injury to personnel.
Wiring
Yaskawa recommends using ring terminals on all drive models. UL/cUL approval requires the use of UL Listed closed-loop crimp terminals when wiring the drive main circuit terminals. Use only the tools recommended by the terminal manufacturer for crimping.
Transporting the Drive
NOTICE: Never steam clean the drive. During transport, keep the drive from coming into contact with salts, fluorine, bromine, phthalate
ester, and other such harmful chemicals.
u
Motor Application Precautions
n
Standard Induction Motors
Low Speed Range
The cooling fan of a standard motor is usually designed to sufficiently cool the motor at the rated speed. As the self-cooling capability of such a motor reduces with the speed, applying full torque at low speed will possibly damage the motor. To prevent
motor damage from overheat, reduce the load torque as the motor slows.
shows the allowable load characteristics for a Yaskawa standard motor. A motor designed specifically for operation with a drive should be used when 100% continuous torque is needed at low speeds.

Insulation Tolerance
NOTICE: Consider motor voltage tolerance levels and motor insulation in applications with an input voltage of over 440 V or particularly
long wiring distances.
High-Speed Operation
NOTICE: Problems may occur with the motor bearings and dynamic balance of the machine when operating a motor beyond its rated speed.
Contact the motor or machine manufacturer.
Torque Characteristics
Torque characteristics differ compared to operating the motor directly from line power. The user should have a full understanding of the load torque characteristics for the application.
Vibration and Shock
The drive allows selection of high carrier PWM control and low carrier PWM. Selecting high carrier PWM can help reduce motor oscillation (drive current derating may be required).
Take particular caution when adding a variable speed drive to an application running a motor from line power at a constant speed. If resonance occurs, use shock absorbing mounts to the motor base and enable the Jump frequency selection to prevent continuous operation in the resonant frequency range.
Audible Noise
The audible noise of the motor varies based on the carrier frequency setting. However, drive current derating may be required.
When using a high carrier frequency, audible noise from the motor is comparable to the motor noise generated when running from line power.
n
Specialized Motors
Multi-Pole Motor
Because the rated current will differ from a standard motor, be sure to check the maximum current when selecting a drive.
Always stop the motor before switching between the number of motor poles. If a regen overvoltage (oV) fault occurs or if overcurrent protection (oC) is triggered, the motor will coast to stop.
Submersible Motor
The rated current of a submersible motor is greater than that of a standard motor, so select the drive accordingly. Use a motor cable large enough to avoid decreasing the maximum torque level from voltage drop caused by a long motor cable.
Explosion-Proof Motor
The motor and the drive must be tested together to be certified as explosion-proof. The drive is not designed for explosionproof areas.
Geared Motor
Make sure that the gear and the lubricant are rated for the desired speed range to avoid gear damage when operating at low speeds or very high speeds. Consult with the manufacturer for applications that require operation outside the rated speed range of the motor or gear box.
18
YASKAWA TOEP YAIQPM 03B YASKAWA AC Drive - iQpump Micro User Manual
i.2 General Safety
Single-Phase Motor
Variable speed drives are not designed to operate with single phase motors. Using capacitors to start the motor causes a highfrequency current to flow to the capacitors and can damage the capacitors. A split-phase start or a repulsion start can burn out the starter coils because the internal centrifugal switch is not activated. The drive is for use with three-phase motors only.
n
Notes on Power Transmission Machinery
Installing an AC drive in machinery that was previously connected directly to the power supply will allow the machine to operate at variable speeds. Continuous operation outside of the rated speeds can wear out lubrication material in gear boxes and other power transmission parts. Make sure that lubrication is sufficient within the entire speed range to avoid machine damage. Note that operation above the rated speed can increase the noise generated by the machine.

It may be difficult to perform maintenance on the cooling fans of drives installed in a vertical row inside an enclosure.
Ensure adequate spacing at the top of the drive to perform cooling fan replacement when required.
Operating the motor in the low-speed range diminishes the cooling effects, increases motor temperature, and may lead to motor damage by overheating.
Reduce the motor torque in the low-speed range whenever using a standard blower cooled motor. If 100% torque is required continuously at low speed, consider using a special drive or vector motor. Select a motor that is compatible with the required load torque and operating speed range.
Do not operate motors above the maximum rated RPM.
Failure to comply may lead to bearing or other mechanical motor failures.
The speed range for continuous operation differs according to the lubrication method and motor manufacturer.
If the motor is to be operated at a speed higher than the rated speed, consult with the manufacturer.
Continuously operating an oil-lubricated motor in the low-speed range may result in burning.

2.1 Section Safety
NOTICE
When the wiring distance is greater than 100 meters, pay special attention to the motor insulation voltage or use a drive-rated motor.
Failure to comply could lead to motor winding failure.
Motor vibration may increase when operating a machine in variable-speed mode, if that machine previously operated at a constant speed.
Install vibration-proof rubber on the motor base or use the frequency jump function to skip a frequency resonating the machine.
The motor may require more acceleration torque with drive operation than with a commercial power supply.
Set a proper V/f pattern by checking the load torque characteristics of the machine to be used with the motor.
The rated input current of submersible motors is higher than the rated input current of standard motors.
Select an appropriate drive according to its rated output current. When the distance between the motor and drive is long, use a cable thick enough to connect the motor to the drive to prevent motor torque reduction.
When using an explosion-proof motor, it must be subject to an explosion-proof test in conjunction with the drive.
This is also applicable when an existing explosion-proof motor is to be operated with the drive. Since the drive itself is not explosion-proof, always install it in a safe place. Be sure to set A1-02 to “0” when using an explosion-proof motor.
Do not use a drive for a single-phase motor.
Replace the motor with a three-phase motor.
If an oil-lubricated gearbox or speed reducer is used in the power transmission mechanism, oil lubrication will be affected when the motor operates only in the low speed range.
The power transmission mechanism will make noise and experience problems with service life and durability if the motor is operated at a speed higher than the rated speed.

IP20/NEMA 1, UL Type 1 enclosure: -10 °C to +40 °C (14 °F to 104 °F)
IP66/NEMA 4X, UL Type 4X enclosure: -10 °C to +40 °C (14 °F to 104 °F)
Drive reliability improves in environments without wide temperature fluctuations.
When using an enclosure panel, install a cooling fan or air conditioner in the area to ensure that the air temperature inside the enclosure does not exceed the specified levels.
Do not allow ice to develop on the drive.
95% RH or less and free of condensation
-20 °C to +60 °C (-4 °F to +104 °F)
Install the drive in an area free from:
• oil mist and dust
• metal shavings, oil, water or other foreign materials
• radioactive materials
• combustible materials (e.g., wood)
• harmful gases and liquids
• excessive vibration
• chlorides
• direct sunlight
For IP66/NEMA 4X, UL Type 4X enclosure drives, install the drive in an environment suitable for IP66/NEMA 4X, UL
Type 4X enclosures:
• NEMA 4X, UL Type 4X – Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow, windblown dust, splashing water, hose-directed water, and corrosion; and that will be undamaged by the external formation of ice on the enclosure.
• IP66 – Dust-tight enclosures to not allow any dust to penetrate. The enclosure guards the drive against powerful jetting water sprayed from any direction and is protected against access to hazardous parts with a wire.
Up to 1000 meters without derating; up to 3000 meters with output current, ambient temperature, and voltage derating.
10 to 20 Hz at 9.8 m/s 2
20 to 55 Hz at 5.9 m/s

Install the drive vertically to maintain maximum cooling effects.
NOTICE: Prevent foreign matter such as metal shavings or wire clippings from falling into the drive during installation and project
construction. Failure to comply could result in damage to the drive. Place a temporary cover over the top of the drive during installation.
Remove the temporary cover before startup, as the cover will reduce ventilation and cause the drive to overheat.
NOTICE: Avoid placing drive peripheral devices, transformers, or other electronics near the drive. Failure to comply could result in erroneous
operation. If such devices must be used in close proximity to the drive, take proper steps to shield the drive from noise.
u
Installation Orientation and Spacing
NOTICE: Install the drive upright as illustrated in
. Failure to comply may damage the drive due to improper cooling.

<1> Remove the jumper when installing an optional DC link choke.
<2> The MC on the input side of the main circuit should open when the thermal relay is triggered.
<3> Self-cooled motors do not require separate cooling fan motor wiring.
<4> Connected using sequence input signal (S1 to S7) from NPN transistor; Default: sink mode (0 V com).
<5> Use only a +24 V internal power supply in sinking mode; the source mode requires an external power supply.
<6> Monitor outputs work with devices such as analog frequency meters, ammeters, voltmeters and wattmeters; they are not intended for use as a feedback-type of signal.
<7> Disconnect the wire jumper between HC and H1 when utilizing the safety input.
Refer to Wiring the Control Circuit
for details on removing the jumper. The wire length for the Safe Disable input should not exceed
30 m.
<8> Note that if the drive is set to trigger a fault output whenever the fault restart function is activated (L5-02 = 1), then a sequence to interrupt power when a fault occurs will result in shutting off the power to the drive as the drive attempts to restart itself. The default setting for L5-02 is 0 (fault output active during restart attempt).
WARNING! Sudden Movement Hazard. Do not close the wiring for the control circuit unless the multifunction input terminal parameter is
properly set (S5 for 3-Wire; H1-05 = “0”). Improper sequencing of run/stop circuitry could result in death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before energizing
the drive. Failure to comply could result in death or serious injury from moving equipment. When programmed for 3-Wire control, a momentary closure on terminal S1 may cause the drive to start.
WARNING! When 3-Wire sequence is used, set the drive to 3-Wire sequence before wiring the control terminals and ensure parameter
b1-17 is set to 0 (drive does not accept a run command at power up (default). If the drive is wired for 3-Wire sequence but set up for 2-Wire sequence (default) and if parameter b1-17 is set to 1 (drive accepts a Run command at power up), the motor will rotate in reverse direction at power up of the drive and may cause injury.
WARNING! When the application preset function is executed (or A1-06 is set to any value other than 0) the drive I/O terminal functions
change. This may cause unexpected operation and potential damage to equipment or injury.

NOTICE: Do not pinch or damage the sealing gasket when attaching the front cover. Damage to the gasket may allow moisture or dust to
enter the protective enclosure and damage drive components.
NOTICE: Do not use silicone sealant with cable glands or front cover to reinforce waterproofing. Corrosive vapors produced by the sealant
can damage circuit boards and compromise the watertight integrity of the protective enclosure.
NOTICE: Use only the recommended multi conductor cable and use only one cable per cable gland. Attempting to pass more than one wire
through a cable gland create a space between wires that reduces the waterproofing and dustproofing capabilities of the cable gland, and may damage the drive.
NOTICE: Properly seal the rubber gasket along the outside of the cable gland. Improper seals may allow water or oil into the drive and
damage components.

Main Circuit Terminal Power Supply and Motor Wiring
This section outlines the various steps, precautions, and checkpoints for wiring the main circuit terminals and motor terminals.
NOTICE: When connecting the motor to the drive output terminals U/T1, V/T2, and W/T3, the phase order for the drive and motor should
match. Failure to comply with proper wiring practices may cause the motor to run in reverse if the phase order is backward.
NOTICE: Route motor leads U/T1, V/T2, and W/T3 separate from all other leads to reduce possible interference related issues. Failure to
comply may result in abnormal operation of drive and nearby equipment.
NOTICE: Do not connect phase-advancing capacitors or LC/RC noise filters to the output circuits. Improper application of noise filters could
result in damage to the drive.
NOTICE: Do not connect the AC power line to the output motor terminals of the drive. Failure to comply could result in death or serious
injury by fire as a result of drive damage from line voltage application to output terminals.
n
Cable Length Between Drive and Motor
When the cable length between the drive and the motor is too long (especially at low frequency output), note that the cable voltage drop may cause reduced motor torque. Drive output current will increase as the leakage current from the cable increases.
An increase in leakage current may trigger an overcurrent situation and weaken the accuracy of the current detection.
Adjust the drive carrier frequency according to the following table. If the motor wiring distance exceeds 100 m because of the system configuration, reduce the ground currents.
to set the carrier frequency to an appropriate level.
Cable Length
Carrier Frequency
Table 3.7 Cable Length Between Drive and Motor
50 m or shorter 100 m or shorter
15 kHz or less 5 kHz or less
Longer than 100 m
2 kHz or less
Note:
When setting carrier frequency, calculate the cable length as the total distance of wiring to all connected motors when running multiple motors from a single drive.
n
Ground Wiring
Follow the precautions to wire the ground for one drive or a series of drives.
WARNING! Electrical Shock Hazard. Always use a ground wire that complies with technical standards on electrical equipment and minimize
the length of the ground wire. Improper equipment grounding may cause dangerous electrical potentials on equipment chassis, which could result in death or serious injury.
WARNING! Electrical Shock Hazard. Be sure to ground the drive ground terminal. (200 V Class: Ground to 100 Ω or less, 400 V Class:
Ground to 10 Ω or less). Improper equipment grounding could result in death or serious injury by contacting ungrounded electrical equipment.
NOTICE: Do not share the ground wire with other devices such as welding machines or large-current electrical equipment. Improper
equipment grounding could result in drive or equipment malfunction due to electrical interference.
NOTICE: When using more than one drive, ground multiple drives according to instructions. Improper equipment grounding could result in
abnormal operation of drive or equipment.
when using multiple drives. Do not loop the ground wire.

Setting the Real Time Clock
The time and date must be set when a new HOA keypad is plugged in and the drive is powered up. The HOA keypad will display the time and date setup screen for 30 seconds. If a button is not pressed during this time, the display will clear and a
“Clock Not Set” alarm will flash. Pressing the F2 (Data) key will display the setting screen again.
n
Feedback Loss Wire Break Alarm
If there is no sensor wired to the drive, a “Feedback Loss – Wire Break” alarm will flash on the display. Providing the proper feedback device signal will clear the Feedback Loss alarm.
The drive requires a feedback device (e.g., pressure transducer, flow meter, etc.) to perform automatic system regulation. Any analog 0~10 V or 4-20 mA feedback device can be used in combination with the drive.
Note:
The factory default setting for the drive is 4~20 mA feedback device connected to analog input A2.

Verifying Parameter Changes: Modified Constants Menu
The Modified Constants Menu lists parameter changes as a result of using an Application Preset (A1-03) or by making manual parameter changes (including Auto-Tuning). The Application Preset changes are contained in the (Appl) folder while all other changes appear in the (Std) folder. The Modified Constants Menu helps determine which settings have been changed, and is particularly useful when replacing a drive. If no settings have been changed in either folder, the Modified Constants folders will read “None Modified”. The Modified Constants Menu also allows users to quickly access and re-edit any parameter settings that have been changed.
Note:
The Modified Constants Menu will not display parameters from the A1 group (except for A1-02) or E5-01 even if those parameters have been changed from their default settings.
The following example details where the drive was initialized to Pump Down Mode (A1-03 = 6009) and then three additional parameters were changed including the deceleration time. The example shows how to then change the deceleration time from
14.0 s to 24 seconds.

Pump Down Level Control Application Preset
This preset allows the drive to regulate the depth of water in a tank or other vessel that is being filled by an external source.
A feedback device that measures water depth is wired to the drive. A PI-control process loop will then modulate the pump speed to pump water out the tank to keep the water depth the setpoint level (pump out at the recharge rate). The drive controller has an application preset to simplify the start up and control of this application.
• System units are in feet (P1-02 = 6).
• Feedback device scaling (P1-03). The feedback device scaling must be entered into the drive for proper control.
• Minimum pump speed (P1-06). Most pumps cannot be run below a certain speed or cavitation can occur.
• Number of Motor Poles (E2-04). The default is for a 2-pole motor.
• Sleep Function. The drive controller will sleep when the system demand is low and awaken when demand returns.
Required Control Wiring
Most depth level transducers have current-based feedback (4-20 mA). The A2 terminal of the drive is preset for 4-20 mA and pre-programmed for PID feedback (H3-10 = B).
Start Up Procedure
1.
Set parameter A1-03 to 6009 (Pump Down Level) to pre-set parameter values for this application.
2.
Set the motor-rated current in parameter E2-01. This information can be found on the motor nameplate or specification sheet.
3.
Set the number of motor poles in parameter E2-04 (2-pole motors have a rated RPM of slightly less than 3600 RPM;
4-pole motors have a rated RPM of slightly less than 1800 RPM). This information can be found on the motor nameplate or specification sheet.
4.
Set the feedback device scaling in parameter P1-03. Check the sensor nameplate or specification sheet. For example, if the device outputs 20 mA at 14.50 ft of water depth, the set P1-03 to 14.50. The drive controller will automatically scale all associated parameters and monitors. Monitor U1-91 (Pump Feedback) will display the measured water depth in feet. The drive has a High Feedback Fault set in parameter P1-11. Make sure that P1-11 is appropriately set for sensor scaling in P1-03.
5.
Set the desired water depth level in parameter Q1-01 (PID setpoint). This is desired water depth that the drive will regulate the pump speed around. To quickly access this parameter, press the HOME key and then the ENTER key.
The U1-99 monitor on the home screen displays the Q1-01 PID setpoint.
6.
Set the minimum speed that the pump can be run in parameter P1-06. The default is 40 Hz. This information can be found on the pump specification sheet.
7.
The default setting does not allow the drive to automatically restart after power loss if the drive was running at the time of power loss. Set P4-10, AUTO Mode Operator Run Power Down Storage, to 1 to enable this feature.
8.
Press the AUTO key to start the drive with PID control (water depth control). Press the OFF key to stop the drive.
9.
The pump can be run in HAND (LOCAL) mode for maintenance purposes by pressing the HAND key while the drive is stopped. The HAND key acts as a start button. Press the OFF button to stop the drive. Press AUTO to return the drive to PID control. The HAND speed reference can be set in P5-02 (Hand Reference 1). Disable the HAND key by setting P5-04 to 0 (disabled).
10.
Configure the sleep function. The pump can be programmed to shut off or “sleep” if the water falls below the depth set in parameter P2-02 (Sleep Level). The controller will monitor the water depth feedback signal and wake up when the water depth rises above the setting in parameter P1-04 (Start/Draw Down Level). Logically, set the Sleep Level

General Purpose Mode Application Preset
The purpose of this mode is to allow the drive controller to run a motor at a set speed without the PID process loop. This preset is designed to simplify using the drive for applications other than pumping control. The default settings call for the frequency reference to be an analog input and the run command to come from the terminal strip via a maintain contact closure. The PID loop is disabled and no process feedback is required.
Required Control Wiring
No additional control wiring is required when the drive controller is at its default settings.
Start Up Procedure
1.
Set parameter A1-03 to 7770 (General Purpose Mode) to pre-set parameter values for this application.
2.
Set the source of the frequency reference for the drive controller in parameter b1-01. The default setting is from the terminal strip via a 0 to 10 V analog signal wired into terminal A1.
3.
Set the source of the Run Command for the drive controller in parameter b1-02. The default setting is from the terminal strip via a maintained contact closure.
4.
Set the Acceleration Time of the motor in parameter C1-01. This is the time to accelerate the motor from zero speed to 60 Hz (E1-04, Maximum Output Frequency).
5.
Determine the stopping method of the motor. The default setting is coast to stop. To ramp the motor to a stop, set b1-03 to 0 and then set the motor deceleration time in parameter C1-02. This is the time to stop the motor from to 60
Hz (E1-04, Maximum Output Frequency) to zero speed.
6.
Set the motor-rated current in parameter E2-01. This information can be found on the motor nameplate or specification sheet.
7.
Set the number of motor poles in parameter E2-04 (2-pole motors have a rated RPM of slightly less than 3600 RPM;
4-pole motors have a rated RPM of slightly less than 1800 RPM). This information can be found on the motor nameplate or specification sheet.
8.
Determine whether the drive controller should attempt to reset itself after a fault. The default setting is disabled. The function is turned on by setting 1 to 10 reset attempts in parameter L5-01 and the time between each reset in parameter
L5-04.
9.
Set the minimum speed at which the motor can run in parameter P1-06. If the system has a minimum safe operation speed, set it in P1-06. This will act as a lower limit of the frequency reference.
10.
The motor can be run in HAND (LOCAL) Mode for maintenance purposes by pressing the HAND key while the drive is stopped. The HAND key acts as a start button. Press the OFF button to stop the drive. Set P5-04 to 0 to disable the HAND key. The default frequency reference is 0.0 Hz in HAND Mode. This can be changed in parameter P5-02.
The AUTO key has no effect with the default settings in the General Purpose Application Preset.

Low City or Low Suction Inlet Pressure
This function is used with low suction inlet pressure switches on pressure booster systems for buildings that get their main water supply from a municipality. This pressure switch enables and disables the pump system when the inlet supply is at a low demand and when running the pump system in this condition will cause damage.
An inlet pressure switch is wired directly into the drive using one of the digital input terminals. If the pressure switch is active and sufficient pressure is available, the drive system will operate normally. If the pressure switch indicates that incoming pressure is too low, the drive will take the following actions:
• The drive will be forced into a sleep-like state (coast to stop).
• Any drives staged in multiplex mode will immediately coast to stop.
• The selected alarm “Low City Pressure”, “Low Suction Pressure”, or “Low Water In Tank” will be displayed (determined by P4-24).
All drives will restart when sufficient pressure returns.
Required Control Wiring
Any one of the multi-function digital inputs (S1 to S7) must be wired and programmed with a low suction inlet pressure switch.
The appropriate terminal parameter (H1-oo) must be to set 73 (Low City Pressure). The action of the switch (normally open / normally closed) is set in parameter P4-21.
Start Up Procedure
1.
Set all other parameters required for the application such as PID control loop, sleep, motor, and I/O parameters.
2.
Set one digital input for the low suction inlet pressure switch (H1-oo = 73). Wire the switch to this terminal.
3.
Configure the terminal for a normally open / closed switch type using parameter P4-21.
4.
Configure the delay times for activating and removing the alarm in parameters P4-23 and P4-24. This can be used to stop the drive from frequent cycling when pressure varies greatly.
5.
Select the alarm message that will be displayed when a Low City condition is detected using parameter P4-24. Options include “Low Cty Pressure”, “Low Suction Pres”, and “Low Watr In Tank”.

Current Limit
This function provides a current limit of the pump (motor). The function is designed to prevent long-term overload conditions of the pump, especially if the motor and drive are oversized compared to the pump. The drive will attempt to limit the output current by reducing the frequency reference. The frequency is reduced using an internal current PID regulator. When the
Current Limit function is active, the alarm "Current Limit Foldback" or “CUr” will be displayed on the digital operator keypad.
This function will only operate correctly when the drive is connected to a variable torque motor load such as a centrifugal pump. More specifically, it will only operate if the load is such that output current increases as output frequency increases
(and vice-versa). The current limit function reduces the pump speed to just above the lower value between the minimum pump speed (P1-06) or the minimum output frequency. If PID mode is enabled (b5-01 > 0), a special limit will be applied to the PID integrator when output current limit is active to prevent integrator wind-up.
Current Limit Foldback
(CUr)
Start Up Procedure
1.
Set all other parameters required for the application such as PID control loop, sleep, motor, and I/O parameters
2.
Turn on the current limit function by setting Q3-01 to 1 (enabled). The default setting is 0 (disabled).
3.
Set the desired current limit in Q3-02. This value should not exceed the motor, pump or drive ratings. This does not change the motor (oL1) or drive (oL2) overload functions.
4.

Speed Follower Deceleration Time Switchover
The iQpump Speed Follower will attempt to match the speed of the Lead Drive after the Lag Drive Fixed Speed Delay.
Consider a scenario wherein the system needs help from an idle drive to maintain system pressure. When the idle drive is called to run, the difference between the setpoint and the feedback may be too small to make the drive accelerate faster. In such cases, the system is configured with these settings:
• Set for Lag Drive Speed Follower
• Add Pump method is Frequency Reference
• Frequency Reference setting close to the maximum frequency
The system will drop the speed after the Lag Drive Fixed Speed Delay expires in order to follow the output frequency of the previously idle drive. This transition may cause unwanted pressure drops. A longer deceleration time will be activated on the lag drives when the system switches the drive that is being followed. The longer deceleration time will be effective for a programmable setting, after which the regular deceleration time is used.
Functional Operation
If P9-05 = 3 (Follow Lead Spd), the lag drive will use the network information and the lead drive output speed as its frequency reference. The lag drive final speed reference is affected by (Lag Follower Gain, P9-30) and then by (Lag Follower Bias,
P9-31).
Lag Drive Speed = ( Lead Drive Speed x Lag Follower Gain ) + Lag Follower Bias
When P9-33 > 0.0 sec, an alternate deceleration time (Lag Follower Decel, P9-32) is used when the drive switches from the latched speed (Lag Fixed Delay, P9-07) to the new Lead drive output frequency. The deceleration time is active for the duration set in P9-33, Lag Follower Deceleration Time Active Time, and will switch back to the regular deceleration rate when it expires.
Note:
Parameter functionality stated below only applies when P1-01 = 3 (MEMOBUS Network)

• Confirm the P9-25 and P9-27 settings on all the drives. P9-25 should be set to the highest H5-01 address and at least one drive should have P9-27 set to 0.
• Cycle main power.
Multiplexing Principle
Always observed by system:
• New drives start as Lead and run in PID mode.
• Only the Lead drive can request staging and de-staging.
• Staging will start a new Lead drive and make the old Lead drive into a Lag drive.
• De-staging will stop the current Lead drive and restore the previous drive as the Lead drive.
Multiplexing Messages
During multiplexing, the drive will display a message when it will be staged in or de-staged out. The message will indicate if it is being staged in or out and display a countdown timer of how long until the change takes place.
One of the following conditions must be met for de-staging to occur:
• High Feedback Quick De-stage
• Low Feedback Quick De-stage
• Normal De-stage
• Low Water Level De-stage
• Suction Pressure De-stage
Drive Run Order
U9-04, Running Queue No:
• Shows the position in the iQpump MEMOBUS running queue.
• U9-04 = 0 for pumps that are not running.
• U9-04 = 1 on the first pump that came on and is still running.
• U9-04 = 2 on the second pump that came on and is still running.
• U9-04 = the number of pumps running for the current Lead drive.

PID Feedback via Network
The Network PID Feedback comes from a drive on the network with a valid analog PID feedback source and can be used as the primary or secondary feedback source for a networked drive.
Set P9-02 to 0 if a drive has an analog PID feedback device installed and switching to network as a backup is not desired.
If a drive has an analog PID feedback device installed and the network PID feedback is considered as a backup, set P9-02 to
1 for no alarm message when switched and set P9-02 to 2 for an alarm.
Set P9-02 to 3 if a drive has no analog PID feedback device installed and relies solely on the analog PID feedback of another networked drive.
Note:
Connect an analog PID feedback device to each drive for best performance.

Simple Duplex System Application Example
A customer requires a duplex system with the following capabilities:
• Control the system pressure using two drives (no PLCs).
• Alternate drives everyday to even out the pump wear.
• Toggle switch for Run command.
• Each drive will have its own feedback transducer. Due to the shut-off valves, the network feedback should not be used as a backup.
• Pump is at optimal running speed when at fixed speed of 54.0 Hz.
• Setpoint is 100 PSI, feedback scale is 145 PSI, start level is 80 PSI.

Duplex System with Fine Tuning Application Example
The customer would like to solve a pump cycling problem. Currently the second drive runs for 10 to 20 seconds at minimum speed then shuts off, letting the first drive run at maximum. This will then run the second drive again and the cycle will repeat.
The customer must also account for system losses when running both pumps by boosting the setpoint by 5 PSI. In the event that the pressure exceeds 125 PSI, the second drive should de-stage if both drives are running. If the pressure exceeds 140
PSI, a high feedback fault should occur and stop the drive.
There are multiple methods to handle the pump cycling problem:
• Lower the lag fixed speed (P9-06)

Multiplexing Stop History
Many irrigation-pumping skids consist of a PM pump (Pressure Maintenance) and typically two larger booster pumps to maintain high flow peak demands. In many cases depending on the number of irrigation zones in combination with the type of sprinkler heads used, the flow demand fluctuates and may not require the use of both larger booster pumps at the same time until higher flow rates are required. The drive Controller "Run Stop" history ensures that both booster pumps alternate each run cycle.

Stop History

Note:
The new lead drive selection also applies to Alternation (P9-03 > 0) and will use the Stop History list when finding the alternate.
Triplex Irrigation Booster System Example
When pressure is dropping, the PM Pump (if installed) will attempt to return the system pressure to the desired setpoint level.
If the PM Pump is not able to return the system to the setpoint pressure, typically due to a greater flow demand, the booster pump #1 will be staged on.
The drive controller will speed up or slow down the pump as needed to maintain the system pressure. When flow decreases and the pump system is no longer required to run, the system will go to sleep waiting for the pressure to drop. On the next run cycle the PM pump will start up again, and instead of running booster pump #1, booster pump #2 is stages on, since booster
#1 ran during the last cycle.
This method ensures that during normal operation both booster pumps will operate evenly as lead or lag pumps each run cycle.
A triplex irrigation booster system has one PM Pump (pressure maintenance) and two larger booster pumps of the same horsepower. The customer would like to ensure that the PM Pump is also the lead pump to recharge the system during low flow usage, but during high demands the booster pumps alternate on each run cycle or if required will both run to support very high flow demands.
• Jockey/PM Pump will also be lead to start.
• Jockey/PM Pump will stage booster pump 1 or 2 and stay running for 20 seconds and then shut off.
• Booster pump 1 will run system and if required, call for booster pump 2 or vice versa.
• On sleep mode, the lead drive for starting will swap back to Jockey/PM Pump.
• System setpoint 100 PSI.
• Pressure drop of 10 PSI will start the Jockey pump.
• All drives have individual transducers rated 200 PSI maximum, but if there is a transducer failure, switch to network.

Before Auto-Tuning the Drive
Check the items below before Auto-Tuning the drive.
n
Basic Auto-Tuning Preparations
• Auto-Tuning automatically determines the electrical characteristics of the motor. This is fundamentally different from other types of Auto-Tuning features used in servo systems.
• Auto-Tuning requires the user to input data from the motor nameplate. Make sure the information written on the nameplate is available before Auto-Tuning the drive.
• For best performance, be sure the drive input supply voltage equals or exceeds the motor rated voltage.
Note:
Performance can be enhanced by using a motor with a base voltage that is 20 V (40 V for 400 V class models) lower than the input supply voltage. This may be of special importance when operating the motor above 90% of base speed, where high torque precision is required.
• Auto-Tuning is not possible with permanent magnet motors.
• To cancel Auto-Tuning, press the OFF key on the LCD operator.
•

Notes on Stationary Auto-Tuning for Terminal Resistance Only
• If the motor cable lead length has been significantly modified after Auto-Tuning has already been performed, perform
Stationary Auto-Tuning with the new cables.
• Perform when using motor cables longer than 50 m with V/f Control.
WARNING! Electrical Shock Hazard. When executing stationary Auto-Tuning for line-to-line resistance only, the motor does not rotate,
however, power is applied. Do not touch the motor until Auto-Tuning is completed. Failure to comply may result in injury from electrical shock.

In order to run the drive and motor, the drive must receive a Run command and an Auto Setpoint command. Parameter b1-01 specifies the origin of the Auto setpoint when in AUTO Mode. Switch to AUTO mode by pressing the AUTO button on the
HOA keypad while the drive is stopped.
Note:
If a Run command is input to the drive without a corresponding Auto setpoint, the Run indicator on the HOA keypad will turn on and the
STOP indicator on the keypad will blink.
If the drive should follow the “HAND Reference” set by the HOA keypad, use HAND Mode by pressing the HAND key and set P5-01 to “1: Hand Reference (P5-02).” The HAND reference can then be entered into the U1-01 monitor parameter in the
“-DRIVE-” Menu.
The 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 keypad.
Prior to programming, it is recommended to select the system units (P1-02) and the feedback device, Scaling (P1- 03) first.
P1-03 will automatically scale the drive setpoint.
Example: P1-02 = 1: PSI
P1-03 = 200, feedback range = 200 PSI.
If the drive should follow an “Auto Set-Point” set by the HOA keypad: Set b1-01 to “0: Operator” (factory default). The Auto setpoint can then be entered into the U5-99 monitor parameter in the “-DRIVE-” menu.
Setting 0: Operator (HOA keypad)

Setting 3: Coast to Stop with Timer (Used for Back Spin Control on Vertical Turbine Pumps)
When the Run command is removed, the drive coasts to a stop. If parameter b1-11 = 0, the coast-timer (Run Delay at Stop) becomes a value determined by a combination of output frequency and C1-02. However, if b1-11 > 0, the Run Delay at Stop timer is set to b1-11. If the Run command is reissued during the Run Delay at Stop timer time, the drive WILL restart when the timer expires without the need to re-cycle the Run command. The Run Delay at Stop timer will operate for both AUTO
Mode and HAND Mode. The Run Delay at Stop timer will still operate when the drive goes to sleep and then wakes up. During the Run Delay at Stop timer execution, the HOA keypad will display a Start Delay message.

Speed Estimation Type Speed Search (b3-24 = 1)
This method can be used for a single motor connected to a drive. It should not be utilized if the motor is one or more frame sizes smaller than the drive, at motor speeds above 130 Hz, or when using a single drive to operate more than one motor.
The Speed Estimation type distinguishes two kinds of operation, Back EMF voltage estimation and DC current injection.
Back EMF Voltage Estimation
This method is used by Speed Search after short Baseblock (e.g. a power loss where the drives CPU kept running and the Run command was kept active). Here the drive estimates the motor speed by analyzing the back EMF voltage. It outputs the estimated frequency and increases the voltage using the time constant set in parameter L2-04. After that the motor is accelerated or decelerated to the frequency reference starting from the detected speed.

<1> Once AC power is restored, the drive will wait for at least the time set to b3-05. If the power interruption is longer than the Minimum Baseblock Time L2-03, the drive will wait for b3-05 after the power has returned before starting Speed Search.
Current Injection
This method is used when there is no detectable back EMF, e.g. after longer power losses, when Speed Search is applied with the Run command (b3-01 = 1) or if an External Search command is used. It injects the DC current set in b3-06 to the motor and detects the speed by measuring the current feedback. The drive outputs the detected frequency and increases the voltage using the time constant set in parameter L2-04. If the resulting current is higher than the level in b3-02 the output frequency is reduced. When the current becomes lower than b3-02 the motor speed is assumed to be found and the drive starts to accelerate or decelerate to the frequency reference.

Notes on Using Speed Estimation Type Speed Search
• Auto-Tuning needs to be first performed if you plan to use Speed Estimation. Perform Auto-Tuning again if the there is a change in the cable length between the drive and motor.
• Use Current Detection to search for speeds beyond 130 Hz or if the application is running multiple motors from the same drive, or if the motor is considerably smaller than the capacity of the drive.
• Speed Estimation may have trouble finding the actual speed if the motor cable very long. Current Detection should be used in such situations.
• Use Current Detection instead of Speed Estimation when operating motors smaller than 1.5 kW. Speed Estimation can end up stopping smaller motors as it might not be able to detect the speed or rotation direction of such small motors.
n
Current Detection Type Speed Search (b3-24 = 0)
Current Detection Speed Search can be applied to any motor. Be aware that sudden acceleration may occur when using Current
Detection with relatively light loads.
This method detects the motor speed by reducing the output frequency and measuring the current. The frequency reduction starts from the maximum output frequency or from the set frequency reference. As long as the output frequency is higher than the rotor speed, the slip will cause a high current. The closer the output frequency 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, the output frequency stops decreasing and normal operation resumes.
The following time chart illustrates how Current Detection Speed Search operates after a momentary power loss:

Note:
After power is restored, the drive waits until the time set to b3-05 has passed before performing Speed Search. Thereby the Speed Search may start not at the end of L2-03 but even later.
When Speed Search is applied using an external Search command or automatically with the Run command, the drive waits for the minimum baseblock time L2-03 before Speed Search is started. If L2-03 is smaller than the time set in parameter b3-05, b3-05 is used as the wait time.

Notes on Using Current Detection Type Speed Search
• Increase the voltage recovery ramp time set to L2-04 if a Uv1 fault occurs when performing Current Detection Speed Search.
• Shorten the Speed Search deceleration time set to b3-03 if an oL1 fault occurs while performing Current Detection Speed
Search.
• Increase the minimum baseblock time set to L2-03 if an overcurrent fault occurs when performing Speed Search after power is restored following a momentary power loss.

b5: PID Control
The drive has a built in PID (Proportional + Integral + Derivative) controller that can be used for closed loop control of system variables such as pressure, temperature etc. The difference between the target and the feedback value (deviation) is fed into the PID controller. The PID controller adjusts the drive output frequency in order to minimize the deviation, providing an accurate control of the system variables.

5.2 b: Application
n
P Control
The output of P control is the product of the deviation and the P gain so that it follows the deviation directly and linearly. With
P control only an offset between the target and feedback remains.
n
I Control
The output of I control is the integral of the deviation. It minimizes the offset between target and feedback value that typically remains when pure P control is used. The integral time (I-time) constant determines how fast the offset is eliminated.
n
D Control
D control predicts the deviation signal by multiplying its derivative (slope of the deviation) with a time constant and adding this to the PID input. This way the D portion of a PID controller provides a braking action to the controller response and can reduce the tendency of oscillations and overshoot.
Be aware that D control tends to amplify noise on the deviation signal, which can result in control instability. D control should therefore only be used when necessary.

PID Feedback Loss Detection
The PID Feedback Loss Detection function can detect broken sensors or broken sensor wiring. It should be used whenever
PID control is enabled to prevent critical machine conditions (e.g. acceleration to max. frequency) caused by a feedback loss.
Feedback loss can be detected in two ways:
• Feedback Low Detection:
Detected when the feedback falls below a certain level for longer than the specified time.
• Feedback High Detection:
Detected when the feedback rises beyond a certain level for longer than the specified time.
The following figure explains the working principle of feedback loss detection when the feedback signal is too low. Feedback high detection works in the same way.

Setting 0: Digital Output Only
A digital output set for “PID feedback low” (H2-oo = 3E) will be triggered if the PID feedback value is below the detection level set to b5-13 for the time set to b5-14 or longer. A digital output set for “PID feedback high” (H2-oo = 3F) will be triggered if the PID feedback value is beyond the detection level set to b5-36 for the time set to b5-37 or longer. Neither a fault nor an alarm is displayed on the digital operator. The drive will continue operation. When the feedback value leaves the loss detection range, the output is reset.
Setting 1: Feedback Loss Alarm
If the PID feedback value falls below the level set to b5-13 for longer than the time set to b5-14, a “FBL - Feedback Low” alarm will be displayed and a digital output set for “PID feedback low” (H2-oo = 3E) will be triggered. If the PID feedback value exceeds the level set to b5-36 for longer than the time set to b5-37, a “FBH - Feedback High” alarm will be displayed and a digital output set for “PID feedback high” (H2-oo = 3F) will be triggered. Both events trigger an alarm output (H1oo = 10). The drive will continue operation. When the feedback value leaves the loss detection range, the alarm and outputs are reset.

b5-32: Integrator Ramp Limit
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. Pressure waves may develop in a pressure regulated systems with long piping and the Integrator Ramp Limit function helps curb instability in the PI controller in such situations.
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.
This feature only applies to the drive standard PI loop. It does not apply to the PI loop associated with the water level control function (well draw-down control) (Q4 parameters).

Unlike standard deceleration, once the Fast-stop operation is initiated, the drive cannot be restarted until the deceleration is complete, the Fast-stop input is cleared, and the Run command is cycled.
A digital output programmed for “During Fast-stop” (H2-01/02/03 = 4C) will be closed as long as Fast-stop is active.

This can help reduce alarm detection and problems with the current monitor that result from leakage current over long wiring distances. This is the same as setting the carrier frequency to 2 kHz.
Note:
Swing PWM uses 2.0 kHz carrier frequency as a base. Applying special PWM patterns minimizes the audible noise of the motor.
Guidelines for Carrier Frequency Parameter Setup
Symptom
Speed and torque are unstable at low speeds.
Noise from the drive is affecting peripheral devices.
Excessive leakage current from the drive.
Lower the carrier frequency.
Remedy
Wiring between the drive and motor is too long.
Audible motor noise is too loud.
<1>
• Lower the carrier frequency
• Set C6-02 to B if an alarm is detected or if leakage current causes a problem with the current monitor.
Increase the carrier frequency or use Swing PWM.
<2>
<1> The carrier frequency may need to be lowered if the motor cable is too long. Refer to the table below.
<2> Default setting is 7 (Swing PWM), equivalent to setting 2 kHz. Increasing the carrier frequency is fine, but remember that the drive rated current falls when the carrier frequency is increased.

Notes on using analog inputs as multi-speed 1 and 2:
• If the frequency reference source is assigned to analog input A1 (b1-01 = 1), then this input will be used for Frequency
Reference 1 instead of d1-01. If the reference source is assigned to the digital operator (b1-01 = 0), then d1-01 will be used as Frequency Reference 1.
• When the analog input A2 function is set to “Auxiliary Frequency” (H3-10 = 2), then the value input to terminal A2 will be used as the Frequency Reference 2 instead of the value set to parameter d1-02. When H3-10 does not equal 2, then d1-02 becomes the reference for Frequency Reference 2.

d4-07: Analog Frequency Reference Fluctuation Limit (Up/Down 2)
This parameter is for handling changes in the frequency reference while the terminal set for Up 2 or Down 2 is enabled. If the frequency reference changes for more than the level set to d4-07, then the bias value will be held, and the drive will accelerate or decelerate following the frequency reference. When the frequency reference is reached, the bias hold is released and the bias follows the Up/Down 2 input commands.
Parameter d4-07 is applicable only if the frequency reference is set by an analog or pulse input.

d4-08: Frequency Reference Bias Upper Limit (Up/Down 2)
Parameter d4-08 sets the upper limit of the Up/Down 2 bias (monitor U6-20) and the value that can be saved in parameter d4-06. Set this parameter to an appropriate value before using the Up/Down 2 function.
Note:
When the frequency reference is set by the digital operator (b1-01 = 0) and d4-01 = 1, the bias value will be added to the frequency reference if no Up/Down 2 command is received for 5 s, and will be reset to 0 afterwards. From that point the bias can be increased up to the limit set in d4-08 again.

d4-09: Frequency Reference Bias Lower Limit (Up/Down 2)
Parameter d4-08 sets the lower limit of the Up/Down 2 bias (monitor U6-20) and the value that can be saved in parameter d4-06. Set this parameter to an appropriate value before using the Up/Down 2 function.
Note:
When the frequency reference is set by the digital operator (b1-01 = 0) and d4-01 = 1, the bias value will be added to the frequency reference if no Up/Down 2 command is received for 5 s, and will be reset to 0 afterwards. If the bias is increased using the Up 2 command, once it is added to the frequency reference the speed cannot be reduced with a Down 2 command if the limit set in d4-09 is 0. In this case make sure to set a negative lower limit in d4-09 to allow speed reduction.

d4-10: Up/Down Frequency Reference Limit Selection
Selects how the lower frequency limit is set when the Up/Down function is used.
Refer to Settings 10 and 11: Up/Down
for details on the Up/Down function in combination with frequency reference limits.
Setting 0: Lower Limit is Determined by d2-02 or Analog Input
The lower frequency reference limit is determined by the higher value of both, parameter d2-02 or an analog input that is programmed for “Frequency Bias” (H3-02/10 = 0).
Note:
If the external reference change over function (H1-oo = 2) used to switch between Up/Down function and analog input as reference source, the analog value would become the lower reference limit when the Up/Down reference is active. Change d4-10 to 1 to make the Up/Down function independent of the analog input value.
Setting 1: Lower Limit is Determined by Parameter d2-02
Only parameter d2-02 sets the lower frequency reference limit.

V/f Pattern Settings
The drive utilizes a set V/f pattern to determine the appropriate output voltage level for each relative to the frequency reference.
There are 15 different preset V/f patterns to select from with varying voltage profiles, saturation levels (frequency at which maximum voltage is reached), and maximum frequencies. Additionally, one custom V/f pattern can be set up by programming parameters E1-04 through E1-10.
V/f Pattern Setup for V/f Control
1.
Set the input voltage for the drive.
Refer to E1-01: Input Voltage Setting on page 155
2.
Set the V/f pattern by: a) choosing one of the 15 preset V/f patterns (E1-03 = 0 to E).
b) select the custom V/f pattern (E1-03 = F, default setting).
3.
When using one of the 15 presets, E1-04 through E1-13 are automatically set. Refer to the description below.
For a custom V/f pattern, E1-04 through E1-13 must be adjusted manually.
Refer to V/f Pattern Settings E1-04 to

WARNING! Sudden Movement Hazard. Ensure start/stop and safety circuits are wired properly and in the correct state before applying
power to the drive. Failure to comply could result in death or serious injury from moving equipment.
WARNING! Sudden Movement Hazard. The drive may start unexpectedly in reverse direction after power up if it is wired for 3-Wire sequence
but set up for 2-Wire sequence (default). Make sure b1-17 is set to “0” (drive does not accept a Run command active at power up). When initializing the drive use 3-Wire initialization. Failure to comply could result in death or serious injury from moving equipment.
Setting 2: External Reference 1/2 Selection
Switches between two different sources of Run Commands and Frequency References. When multi-function digital input selection 2 (Ext Ref Sel) is programmed, the Run Command and Frequency Reference source can be switched between External
Reference 1 (b1-01/b1-02) and External Reference 2 (b1-15/b1-16) if the drive is in AUTO mode.
Settings 3 to 5: Multi-Step Speed Reference 1 to 3
Switches multi-step speed frequency references d1-01 to d1-08 by digital inputs.

Setting A: Accel/Decel Ramp Hold
When the digital input programmed for the Accel/decel ramp hold function closes, the drive locks (holds) the output frequency.
Acceleration or deceleration resumes when the input is reopened.
If the Accel/decel ramp hold function is enabled (d4-01 = 1), the drive saves the output frequency to memory when the Ramp
Hold input is closed. When the drive is restarted after stop or after power supply interruption, the saved output frequency becomes the frequency reference (provided that the Accel/decel ramp hold input is still closed).
Setting B: Drive Overheat Alarm (oH2)
Triggers an oH2 alarm when the contact closes. Drive operation is not affected because this is an alarm.

5.7 H: Terminal Functions
Setting C: Analog Terminal Input Selection (Terminal A1, A2)
When closed, the terminals specified in H3-14 are enabled. When open, the drive disregards the input signal to the analog terminals.
Setting F: Not Used/Through Mode
Select this setting when using the terminal in a pass-through mode. When set to F, an input does not trigger any function in the drive. Setting F, however, still allows the input status of the terminal (open or closed) to be read out by a PLC via a communication option or MEMOBUS/Modbus communications. The drive input terminals can then be used as remote I/O by the PLC.
Settings 10 and 11: Up/Down Function
The Up/Down function allows the frequency reference to be set by two push buttons when one digital input is programmed as the Up input (H1-oo= 10) to increase the frequency reference and the other digital input is programmed as the Down input
(H1-oo= 11) to decrease the frequency reference.
The Up/Down function takes priority over the frequency references from the digital operator, the analog inputs, and the pulse input (b1-01 = 0, 1, 4). When using the Up/Down function, references provided by these sources will be disregarded.

Note:
1. An oPE03 alarm occurs when only one of the Up/Down functions is programmed to a digital input.
2. An oPE03 alarm occurs when the Up/Down function is assigned to the terminals and a different digital input is programmed for the
Accel/decel ramp hold function. For more information on alarms,
Refer to Drive Faults, Alarms, Errors, and Messages on page
.
3. The Up/Down function can only be used for External reference 1. Consider this when using Up/Down and the external reference switching command (H1-oo = 2).
Using the Up/Down Function with Frequency Reference Hold (d4-01)
• If the frequency reference hold function is disabled (d4-01 = 0), the Up/Down frequency reference will be reset to 0 when the Run command is cleared or the power is cycled.
• When d4-01 = 1, the drive will save the frequency reference set by the Up/Down function. When the Run command or the power is cycled, the drive will restart with the saved reference value. Close the Up or Down input without an active Run command to reset the saved value.
Using the Up/Down Function with Frequency Reference Limits
Parameter d2-01 determines the upper frequency reference limit.
The value for the lower frequency reference limit depends on the parameter d4-10 setting. This value can be set by an analog input or parameter d2-02. When a Run command is applied, the lower limits function as follows:
• If the lower limit is set by d2-02 only, the drive accelerates to this limit as soon as a Run command is entered.
• If the lower limit is determined by an analog input only, the drive accelerates to the limit when both the Run command and an Up or Down command are active. The drive will not start running if only the Run command is active.
• If the lower limit is set by both an analog input and d2-02, and the analog limit is higher than the d2-02 value, the drive accelerates to the d2-02 value when a Run command is input. When the d2-02 value is reached, the drive accelerates to the analog limit only if an Up or Down command is set.
shows an Up/Down function example with a lower frequency reference limit set by d2-02, and the frequency reference hold function both enabled and disabled.

Settings 12 and 13: Forward Jog, Reverse Jog
Digital inputs programmed as Forward Jog (H1-oo = 12) and Reverse Jog (H1-oo = 13) are Jog inputs that do not require a Run command. Closing the terminal set for Forward Jog input will cause the drive to ramp to the Jog frequency reference
(d1-17) in the forward direction. The Reverse Jog will cause the same action in the reverse direction. The Forward Jog and
Reverse Jog command can be set independently.
Note:
The Forward Jog and Reverse Jog commands override all other frequency references. However, if the drive is set to prohibit reverse rotation
(b1-04 = 1), activating Reverse Jog will have no effect. Inputting both the Forward Jog and Reverse Jog are simultaneously for 500 ms or longer will trigger an alarm will and the drive will ramp to stop.

Setting 14: Fault Reset
When the drive detects a fault condition, the fault output contact closes, the drive output shuts off, and the motor coasts to stop (specific stopping methods can be selected for some faults such as L1-04 for motor overheat). After removing the Run command, clear the fault either by pressing the RESET key on the digital operator or closing a digital input configured as a
Fault Reset (H1-oo = 14).
Note:
Remove the Run command prior to resetting a fault. Fault Reset commands are ignored while the Run command is present.
Settings 15 and 17: Fast Stop (N.O., N.C.)
The Fast Stop function operates similar to an emergency stop input to the drive. If a Fast Stop command is input while the drive is running, the drive decelerates to a stop in the deceleration time set to C1-09. The drive can only be restarted after bringing the drive to a complete stop, turning off the Fast Stop input, and switching off the Run command.
• To trigger the Fast Stop function with an N.O. switch, set H1-oo = 15.
• To trigger the Fast Stop function with an N.C. switch, set H1-oo = 17.

Setting 18: Timer Function Input
This setting configures a digital input terminal as the input for the timer function. Use this setting combination with the timer function output (H2-oo = 12).
Setting 19: PID Disable
Close a digital input to indefinitely disable the PID function. When the input is released, the drive resumes PID operation.
Setting 1B: Program Lockout
Parameter values cannot be changed when an input is programmed for Program Lockout and the input is open. It is still possible, however, to view and monitor parameter settings.
Setting 1E: Reference Sample Hold
This function allows the user to sample an analog frequency reference signal being input to terminal A1, A2, or A3 and hold the frequency reference at the sampled level. When the Analog Frequency Reference Sample/Hold function is held for at least
100 ms, the drive reads the analog input and changes the frequency reference to the newly sampled speed as illustrated in
.
When the power is shut off and the sampled analog frequency reference is cleared, the frequency reference is reset to 0.

Settings 20 to 2F: External Fault
The External fault command stops the drive when problems occur with external devices.
To use the External fault command, set one of the multi-function digital inputs to a value between 20 and 2F. The digital operator will display EFo where o is the number of the terminal to which the external fault signal is assigned.
For example, if an external fault signal is input to terminal S3, “EF3” will be displayed.

Setting 8F: Low Water Level
Function is active in AUTO Mode during normal operation and is also used with Pre-charge function.
Function depends on P1-30, Low Water Digital Input Configuration, setting.
When P1-30 = 0 (N.O.): Closed: Low Water Level Fault. Open: Reservoir/Tank is filled to normal level.
When P1-30 = 1 (N.C.): Closed: Reservoir/Tank is filled to normal level. Open: Low Water Level Fault.
Pre-charge function uses low water level input as “Tank/Reservoir” feedback to indicate water level reached.
Setting 90: High Water Level
Function is active when the drive is running and depends on P1-31, High Water Digital Input Configuration, setting.
When P1-31 = 0 (N.O.): Closed: High Water Level Fault. Open: Reservoir/Tank is filled to normal level.
When P1-30 = 1 (N.C.): Closed: Reservoir/Tank is filled to normal level. Open: High Water Level Fault.
Setting 95: Remove Drive Disable
Prevents the drive from running when active for the time set in P4-26. Must be inactive for the time set in P4-27 to allow the drive to run again.
Note:
Parameter P4-25 determines whether this input is Normally Open or Normally Closed.
Setting B0: Emergency Override Function
The Emergency Override function is activated by closing the digital input programmed for Emergency Override Forward Run
(H1-oo = AF) or Emergency Override Reverse Run (H1-oo = B0).
If H1-oo = 6A (Drive Enable) is programmed, it must be opened to disable the drive for Emergency Override to take effect.
Closing both Emergency Override digital inputs at the same time will trigger an External Fault (EF) error.
When the drive is in Emergency Override, the frequency reference source is dependent on parameter S6-02, Emergency
Override Reference Selection. When S6-02 is set to 0 (Use S6-01 Reference), the drive will run at the S6-01 setting. When
S6-02 is set to 1 (Use Frequency Ref), the drive will use the currently selected frequency reference (based on b1-01 and HAND/
AUTO) as the run speed.
An alarm will flash during Emergency Override indicating that the function is active and the direction the drive is commanded to run.
Resettable faults occurring when Emergency Override is activated will be cleared.
The drive will perform unlimited speed search retries during Emergency Override.
When Emergency Stop is active and Emergency Override is activated, the drive will run in Emergency Override mode.
The CALL (Serial Communication Error) mechanism is deactivated when Emergency Override is activated.
The Emergency Override function has priority over the PID Sleep feature (b5-15/b5-16).
Setting AF: Emergency Override Forward Run
Enables Emergency Override Forward Run (Enabled when S6-01 = 1).
Setting B0: Emergency Override Reverse Run
Enables Emergency Override Reverse Run (Enabled when S6-01 = 1).

Setting 0: Frequency Bias
The input value of an analog input set to this function will be added to the analog frequency reference value. Use this setting also when only one analog input is used to supply the frequency reference.
By default both analog inputs A1 and A2 are set for this function. Using both A1 and A2 at the same time increases the frequency reference by the total of both inputs.
Example: If the analog frequency reference by analog input A1 is 50% and a bias of 20% is applied by analog input A2, the resulting frequency reference will be 70% of the maximum output frequency.
Setting 1: Frequency Gain
The input value of an analog input set to this function will be multiplied with the analog frequency reference value.
Example: If the analog frequency reference from analog input A1 is 80% and a gain of 50% is applied from analog input A2, the resulting frequency reference will be 40% of the maximum output frequency.
Setting 2: Auxiliary Reference
Sets the auxiliary frequency reference when Multi-Step Speed operation is selected.
Refer to Multi-Step Speed Selection on page 147
for details.
Setting 4: Voltage Bias
Voltage bias boosts the output voltage of the V/f curve as a percentage of the maximum output voltage (E1-05). Available only when using V/f Control.
Setting 7: Overtorque/Undertorque Level
Overtorque level sets the overtorque/undertorque detection level using the analog input. This works with Torque Detection
Selection 1 (L6-01) and will take the place of the torque detection level set to L6-02. For V/f Control, this function is based on 100% of the drive rated current.
Refer to L6: Torque Detection on page 205
for details on torque detection.
Setting B: PID Feedback
An input set for this function supplies the PID feedback value. This setting requires PID operation to be enabled in b5-01.
Refer to PID Feedback Input Methods on page 131
Setting C: PID Setpoint
An input set for this function supplies the PID setpoint value. The frequency reference selected in parameter b1-01 no longer
becomes the PID se point. This setting requires PID operation to be enabled in b5-01.
Setting E: Motor Temperature
In addition to or in place of the oL1 (motor overload) fault detection, it is possible to use a PTC (Positive Temperature
Coefficient) thermistor for motor insulation protection.
Refer to Motor Protection Using a Positive Temperature Coefficient
for detailed explanations.
Setting F: Not Used
Any analog input that is not used should be set to F. When set to “F”, an input does not affect any drive function but the input level can be read out by a PLC via a communication option or MEMOBUS/Modbus communications (through mode). This way drive analog inputs can be used to read out external sensor values if there is a lack of PLC analog inputs.
Setting 16: Differential PID Feedback
If an analog value is set for this function, the PID controller is set for differential feedback. The subtraction of the PID feedback

Kinetic Energy Backup (KEB) Function
In case of a power loss, the KEB function can decelerate the motor and use the rotational energy of the machine to backup/ maintain the drive DC bus for a certain period of time. This allows the drive to continue running without interrupting the output power during a momentary power loss. Once the power is restored, the drive smoothly returns to the same operational state before the power loss occurred. The KEB function supports two different operation modes.
KEB 1
In this mode the drive decelerates the motor based on the deceleration time set in parameter L2-06/C1-09 in order to keep the
DC bus voltage level high. When the power supply returns, it uses the time set to L2-07 or the selected acceleration time to accelerate back to the frequency reference.

Note:
If L2-06 is set to 0.0 s, C1-09 is used instead. If L2-07 is set to 0.0 s, the drive reaccelerates using the selected acceleration time.
Use this method with setting parameters L2-06 and L2-07 if multiple drives must decelerate but still keep the speed ratio between the drives constant during power loss. In this case, a braking resistor is required in order to avoid overvoltage trips.
KEB 2
In this mode the drive decelerates the motor by calculating the energy of the rotating system. The deceleration rate is continuously adjusted so that the DC bus voltage meets the level set in parameter L2-11. The rotational energy is estimated using the parameters L3-24 and L3-25. When the power supply returns, the drive accelerates back to the frequency reference using the selected acceleration time.
Activation and Deactivation of the KEB Function
The KEB function requires parameter L2-01 to be set to 1 or 2 and a digital input has to be configured for the KEB 1
(H1-oo = 65/66) or KEB 2 (H1-oo = 7A/7B) command. The input has to be enabled during KEB.
Refer to Settings 65 and 66: KEB Ride-Thru 1 (N.C.), 2 (N.O.) on page 170
Refer to Settings 7A and 7B: KEB Ride-Thru 2 (N.C., N.O.) on page 172
for details on setting the KEB input commands.
The KEB function is automatically activated when one of the conditions below becomes true.
• The DC bus voltage falls below the level set in parameter L2-05. The KEB input has to be set within 50 ms after the KEB function was activated, or the drive will assume the power supply has returned and attempt to restart.
• The input programmed for KEB 1 or 2 is activated. This input should be triggered by an external undervoltage detection relay.
The KEB function ends when one of the conditions below become true.
• The KEB input was released or
• The function was activated by DC bus voltage detection and no KEB input was set within 50 ms after the KEB activation.

L3: Stall Prevention
When the load is too high or acceleration and deceleration times are too short, the motor may be unable to keep up with the frequency reference, resulting in excessive slip. This “stalling” makes it impossible to decelerate or accelerate.

The Stall Prevention function can be set separately for acceleration, operating at constant speeds, and deceleration.

When this setting is used, the drive decelerates according to the set deceleration time. With high inertia loads or rapid deceleration, an overvoltage (ov) fault may occur. In this case use braking options or switch to another L3-04 selection.
Note:
Use this setting or set L3-04 to 3 whenever a Dynamic Braking Resistor or another braking option is used.
Setting 1: General Purpose Stall Prevention
With this setting the drive tries to decelerate in the set deceleration time. When the DC bus voltage exceeds the Stall Prevention level, the drive pauses deceleration. Deceleration continues as soon as the DC bus voltage drops below that level. Stall
Prevention may be triggered repeatedly to avoid an overvoltage fault. The DC bus voltage level for Stall Prevention depends on the input voltage setting E1-01.

Setting 2: Intelligent Stall Prevention
With this setting the drive adjusts the deceleration rate so that the DC bus voltage is kept at the level set in parameter L3-17.
This way the shortest possible deceleration time is achieved while the motor is protected from stalling. The deceleration time that has been selected is disregarded, but the achievable deceleration time cannot be smaller than 1/10 of the set deceleration time.
This function uses the following parameters for adjusting the deceleration rate:
• DC bus voltage gain L3-20
• Deceleration rate calculations gain L3-21
• Inertia calculations for motor acceleration time L3-24
• Load inertia ratio L3-25
Refer to these parameter descriptions for details.
Note:
As the deceleration time is not constant, Intelligent Stall Prevention should not be used in applications where stopping accuracy is a concern.
Use braking options instead.
Setting 3: Stall Prevention with Braking Option
Enables the Stall Prevention function while using a braking resistor. Use this setting if overvoltage occurs with L3-04 disabled when using a braking resistor. This makes it possible to reduce the deceleration time.

Setting 4: Overexcitation Deceleration
Enables overexcitation deceleration. Overexcitation Deceleration (increasing the motor flux) shortens the deceleration time compared to deceleration with no Stall Prevention (L3-04 = 0). Repetitive or long overexcitation deceleration can result in motor overheat. In such situations, either shorten the deceleration time setting or use a braking resistor option.
Use parameters n3-13 and n3-23 for fine-tuning this function.
Note:
Because the allowable flux level for overexcitation varies based on the flux saturation characteristics of the motor, set the proper overexcitation level by adjusting the excitation gain in parameter n3-13. Motor characteristics and inertia of the machine influence the deceleration time during overexcitation deceleration.
Setting 7: Overexcitation Deceleration 3
Provides faster deceleration than normal Overexcitation Deceleration (L3-04 = 4) by increasing the amount of overexcitation current applied to the motor.
Note:
When operation permits, use normal Overexcitation Deceleration (L3-04 = 4).

The output frequency is adjusted during ov suppression so that the DC bus voltage does not exceed the level set in parameter

• Deceleration rate calculations gain L3-21

Note:
The torque detection function uses a hysteresis of 10% of the drive rated output current/motor rated torque.
When overtorque occurs in the application, the drive may stop due to overcurrent (oC) or overload (oL1). To prevent this, an overload situation should be indicated to the controller before oC or oL1 occur in the drive. Use the torque detection for this purpose. Use undertorque detection to discover application problems like a torn belt, a pump shutting off, or other similar trouble.

If an overheat alarm occurs, the operation is continued but the speed is reduced to the level set in parameter L8-19. If after 10 s the oH alarm is still present, the speed is reduced once more. The amount of reduction depends on how often the alarm repeats. If the oH alarm disappears while the drive is operating at a reduced speed, then the drive will switch back to the
previous speed it was reduced to before.

• NOT in HAND Mode
• “Disable Pre-charge” digital input NOT closed
• P4-03 > 0.0
• If P4-01, Pre-Charge Level, is greater than 0, the PID feedback must be below the P4-01 level. (Forward acting PID, b5-09
= 0, Reverse acting PID, b5-09 = 1).
When the drive enters Pre-Charge Mode 1 and 2, the drive runs at the Pre-Charge frequency set in P4-02/P4-06, the PID controller is disabled and the Pre-Charge digital output (H2-0o = A4) closes.

Additionally, during Pre-Charge Mode:
• When Pre-charge Level 2 (P4-32) is set to 0, the system can exit Pre-charge when the PID Feedback goes above the Precharge Level (P4-01) in normal PID operation, or below the P4-01 level in inverse PID operation.
However, when Pre-charge Level 2 (P4-32) is set to a non-zero value, the system goes into Pre-Charge 2 instead when Pre-
Charge 1 completes via timer (P4-03) or level (P4-01). At this point, the drive will run at Pre-charge Frequency 2 (P4-06).
The system can exit Pre-charge 2 when the PID Feedback goes above the Pre-charge Level 2 (P4-32) in normal PID operation, or below the P4-32 level in inverse operation.
• When P4-02, Pre-Charge Frequency, or P4-06, Pre-Charge Frequency 2, are set to a value less than P1-06, Minimum Pump
Speed, the alarm “Freq. Ref < Pump Min P1-06” is displayed and the drive runs at the minimum speed.
• When Pre-Charge Loss of Prime parameters P4-05 and P4-08 are set to 0, the Loss of Prime detection is disabled.
• When Pre-Charge Loss of Prime parameters P4-05 or P4-08 are set to a value greater than 0, Loss of Prime detection will operate after the output speed reaches the Pre-Charge Frequency set in P4-02 or P4-06.

P7: Anti-Jam
Anti-Jam is a method to detect and attempt to expel solids that preventing the pump impeller from turning.
The drive monitors the output current when starting from zero speed. When the current goes too high, the motor will coast to stop and switch into reverse. This cycle is repeated until the output current remains below the detection level or until the drive faults out on an “AJF – Anti-Jam Fault”.
WARNING! Sudden Movement Hazard. The Anti-Jam function can force the motor to briefly run in the reverse direction and may cause
injury even if parameter b1-04 is set to “Reverse Disabled”. Be sure all personnel are clear of rotating machinery.

The drive Analog PI feedback signal and status are sent to the iQpump MEMOBUS network. The status is dependent on b5-12,
PI Feedback 4 to 20 mA Detection, 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 used as the Network PI Feedback and is constantly sent to all the drives in the network.
When the current Lead drive does not have a good status, the Network PI Feedback is taken from another drive that has a good status.
When there is no Analog Feedback signal for PI Feedback, the drive uses the Network PI Feedback register when it is allowed and an alarm can flash if desired.
When P1-01 is set to 3, b5-12 > 0, and the PI source is 4 to 20 mA, the analog feedback detection process starts automatically for all drives that have P9-02 ≠ 3 and are ready to run on the network as soon as one of the drives receives a Run command is not running in Pre-charge mode. Drives that fail on the feedback detection will indicate that their feedback signals are invalid and will not be considered by the iQpump MEMOBUS Network as good sources. The network reads out the valid signals selected using lead-drive priority, and sends it back to all the drives as the Network PI Feedback. If the current lead drive has a valid analog feedback signal, 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 Network. In both cases, a status bit is also sent out indicating that the network has a good feedback source.
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 the stopping method is fixed to coast-to-stop.
Any drive with b5-12 set to 0 and P9-02 ≠ 3 will effectively have no feedback loss detection and will continuously send the
Analog PI Feedback to the iQpump Network regardless if it is a healthy signal.
When b5-12 is set to 2 and P9-02 ≠ 3, PI Feedback detection will cause an alarm instead when one of the following conditions exists:
• The drive is in HAND Mode
• There is no Lead drive on the network
• The drive is not in AUTO Mode
Setting 0: Analog only
The drive will never read the Network PI Feedback register as the feedback source, although the drive will still transmit its own PI Feedback signal to the network. The feedback detection is based on parameter b5-12.
Setting 1: Ana->Net, No alarm
The drive reads the Network PI Feedback register if the analog feedback detection determines a signal loss. If the network feedback signal is also invalid, it will act according to b5-12. Setting b5-12 to 0 or using a non-4 to 20 mA PI Feedback signal disables analog feedback detection and prevents the drive from switching to the Network PI Feedback.
Setting 2: Ana->Net, Alarm
The drive reads 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 the b5-12 setting. Setting b5-12 = 0 or using a non-4 to 20 mA PI
Feedback signal disables analog feedback detection and prevents the drive from switching to the Network PI Feedback.
Setting 3: Network only
The drive will always read the Network PI Feedback register.

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) where the First drive is defined as the first pump that was run in the system and the Last drive is defined as the Lead Drive. When the timer expires, the drive is removed from the system, turned-off, and a new lead drive is brought online to replace it.
Alternation is enabled when P9-03, Alternation Time, is set to a non-zero value. In FIFO, the timer is run on the first drive and 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 network.
Setting 0: First in, first out auto
Removes the first drive in the running queue and starts the lead drive automatically (if needed) using the MEMOBUS Multiplex function. When there is only one drive running, then the new lead drive is forced to run since the MEMOBUS Multiplex function cannot run if there is no lead drive.

When a system fault is detected, the iQpump MEMOBUS Network sends out a system message to all other drives informing them of the fault, stops all drives that are running, and prevents any drives from running until the fault is cleared.
When Fault Restarts are enabled, system faults do not consume L5-01 attempts, but instead use P9-22. The system fault retry attempts apply to all the drives on the network and are incremented when a drive with a system fault auto-restarts. Set this parameter to the same value on all drives in the MEMOBUS network for proper operation.
The following faults are considered system faults on the MEMOBUS network and work as described below:
Not Maintaining Setpoint: Active on the lead drive in the network. When the lead drive has an NMS fault, it will stop all other network drives and prevent the drives from running until the fault is cleared. The HOA keypad display message “Net
Pump Err” is displayed on all other network drives.
Low Feedback / Low Water Level: Active on any network drive. When the drive has an LFB or LWL fault, it will stop all other network drives and prevent the drives from running until the fault is cleared. The HOA keypad display message “Net
Pump Err” is displayed on all other network drives.
High Feedback / High Water Level: Active on any network drive. When the lead drive has an HFB or HWL fault, it will stop all other network drives and prevent them from running until the fault is cleared. The HOA keypad display message “Net
Pump Err” is displayed on all other network drives.
Flow Meter: Low Flow, High Flow, and Accumulated Level:Active on any network drive that has an Auto Run command.
When the drive has a LOWFL, HIFLO, or ACCUM fault, the network stops all other drives and prevent them from running until the fault is cleared. The HOA keypad display message “Net Pump Err” is displayed on all other network drives.
Setting P9-22 to 0 disables the system restart regardless of L5-01, P4-07, and P4-08 parameter settings. When P9-22 > 0, and
L5-01 = 0 or P4-07/P4-08 are set to disable the fault restart, when that drive gets a system fault, the system will not be able to restart.
When 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 increase. When the system fault restart counter equals the P9-22 setting, the iQpump MEMOBUS
Network disables automatic fault restart and manually resetting the fault will clear the system fault restart counter. If the iQpump MEMOBUS Network does not experience a system fault for 10 minutes, it clears the system restart fault counter.

Losing power or communications to a drive with a system fault will clear the fault and allow other drives in the system to run.

Alarm Codes, Causes, and Possible Solutions
Alarms are drive protection functions that do not necessarily cause the drive to stop. After removing the cause of an alarm, the drive will return to its previous status before the alarm occurred.
When an alarm has been triggered, the ALM light on the digital operator display blinks and the alarm code display flashes. If a multi-function output is set for an alarm (H2-oo = 10), that output terminal will be triggered.
Note:
If a multi-function output is set to close when an alarm occurs (H2-oo = 10), it will also close when maintenance periods are reached, triggering alarms LT-1 through LT-4 (triggered only if H2-oo = 2F).

Power electronics have limited life and may exhibit changes in characteristics or performance deterioration after years of use under normal conditions. To help avoid such problems, it is important to perform preventive maintenance and periodic inspection on the drive.
Drives contain a variety of power electronics such as power transistors, semiconductors, capacitors, resistors, fans, and relays.
The electronics in the drive serve a critical role in maintaining proper motor control.
Follow the inspection lists provided in this chapter as a part of a regular maintenance program.
Note: The drive will require more frequent inspection if it is placed in harsh environments, such as:
• High ambient temperatures
• Frequent starting and stopping
• Fluctuations in the AC supply or load
• Excessive vibrations or shock loading
• Dust, metal dust, salt, sulfuric acid, chlorine atmospheres
• Poor storage conditions.
Perform the first equipment inspection one to two years after installation.

u
Terminal Board Overview
The drive has a modular I/O terminal block that facilitates quick drive replacement. The terminal board contains on-board memory that stores all drive parameter settings and allows the parameters to be saved and transferred to the replacement drive by disconnecting the terminal board from the damaged drive then reconnecting the terminal board to the replacement drive.
There is no need to manually reprogram the replacement drive.
Note:
When transferring the removable terminal block with backup memory to a drive with a different voltage class or different output capacity, set A1-03 to 2220 to initialize the drive after installing the terminal block.

A.4 Drive Derating Data
A.4 Drive Derating Data
The drive can be operated at above the rated temperature, altitude, and default carrier frequency by derating the drive capacity.
u
Single-Phase Derating
iQpump Micro drives are compatible for use with both three-phase and single-phase input power supplies. The drive output to the motor is always three-phase, regardless of number of input phases.
Output capacity to the motor is derated when using single-phase input power and the drive firmware includes protection for single-phase input applications. This protection is enabled by default. Disabling this protection for single-phase input applications can void warranty and result in premature failure.
Selection of larger models always results in greater output capacity to the motor when supplying the drive with three-phase input power. However, the selection of larger models does not always yield greater output capacity when using the drive with single-phase input power.
Several factors affect the amount of derated drive output capacity when single-phase input power is supplied to the drive:
• Single-phase input voltage level
• Motor voltage rating
• Amount of input impedance.
The tables in this section assist in model selection by considering factors that affect the amount of derating in single-phase input power applications.
n
Single-Phase Input Sizing
The rated output current listed in the tables allows for a 120% overload for 60 seconds. Contact Yaskawa if assistance is needed in selecting drive models with higher overload requirements. Adding more impedance than is specified will degrade performance.

Detects loss of prime in the pump when a wire break condition has occurred.
When the measured quantity determined by P1-18 (output current, kilowatts, or power) drops below this level for the time set in P1-20 and the output frequency is at the level set in b5-13, a “Loss of Prime” condition occurs.
The drive responds to the “Loss of Prime” condition depending on the setting of P1-22, Loss of Prime Selection.
When b5-12 = 3 and the Feedback signal is lost, the drive will run at the b5-13 speed for the b5-15 time, after which the drive will fault on Feedback Loss (FDBKL).

C.1 Section Safety
DANGER
Electrical Shock Hazard
Do not connect or disconnect wiring while the power is on.
Failure to comply will result in death or serious injury.
Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait at least one minute after all indicators are OFF and measure the DC bus voltage level to confirm safe level.
WARNING
Do not operate equipment with covers removed.
Failure to comply could result in death or serious injury.
Do not perform work on the drive while wearing loose clothing, jewelry or without eye protection.
Failure to comply could result in death or serious injury.
Remove all metal objects such as watches and rings, secure loose clothing and wear eye protection before beginning work on the drive.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
Do not allow unqualified personnel to use equipment.
Failure to comply could result in death or serious injury.
Maintenance, inspection and replacement of parts must be performed only by authorized personnel familiar with installation, adjustment and maintenance of AC drives.
Before wiring terminals, disconnect all power to the equipment.
The internal capacitor remains charged even after the power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait at least one minute after all indicators are OFF and measure the DC bus voltage level to confirm safe level.
Fire Hazard
Tighten all terminal screws to the specified tightening torque.
Loose electrical connections could result in death or serious injury by fire due to overheating of electrical connections.
CAUTION
Crush Hazard
Do not carry the drive by the front cover.
Failure to comply may result in minor or moderate injury from the main body of the drive falling.
NOTICE
Observe proper electrostatic discharge procedures (ESD) when handling the drive and circuit boards.
Failure to comply may result in ESD damage to the drive circuitry.
Check all the wiring to ensure that all connections are correct after installing the drive and connecting any other devices.
Failure to comply could result in damage to the drive.

C.2 MEMOBUS/Modbus Configuration
C.2 MEMOBUS/Modbus Configuration
Drives can be controlled from a PLC or other master device via serial communications using the MEMOBUS/Modbus protocol.
MEMOBUS/Modbus communication can be configured using one master (PLC) and a maximum of 255 slaves. The drive has slave functionality only, meaning that serial communication is normally initiated from the master and responded to by the slaves.
The master performs serial communications with only one slave at a time. The address or node for each slave must be set beforehand so that the master can communicate with the slave at that address. A slave that receives a command from the master will perform the specified function and then send a response back to the master.

C.6 Drive Operations by MEMOBUS/Modbus
The drive operations that can be performed by MEMOBUS/Modbus communication depend on drive parameter settings. This section explains the functions that can be used and related parameter settings.
u
Observing the Drive Operation
A PLC can perform the following actions with MEMOBUS/Modbus communications at any time regardless of parameter settings (except H5-oo).
• Observe drive status and drive control terminal status from a PLC.
• Read and write parameters.
• Set and reset faults.
• Set multi-function inputs. Inputs settings from the input terminals So and from MEMOBUS/Modbus communications are both linked by an OR operation.
u
Controlling the Drive

C.7 Communications Timing
C.7 Communications Timing
To prevent overrun in the slave drive, the master should wait a certain time between sending messages to the same drive. In the same way, the slave drive must wait before sending response messages to prevent an overrun in the master. This section explains the message timing.
u
Command Messages from Master to Drive
In order to prevent overrun and data loss, the master must wait between receiving a response and sending the same type of command as before to the same slave drive. The minimum wait time depends on the command as shown in the table below.

u
Message Content
In MEMOBUS/Modbus communications, the master sends commands to the slave, and the slave responds. The message format is configured for both sending and receiving as shown below, and the length of data packets depends on the command
(function) content.

Slave Address
The slave address in the message defines the note the message is sent to. Use addresses between 0 and 20H. If a message with slave address 0 is sent (broadcast), the command from the master will be received by all slaves. The slaves do not provide a response to a broadcast type message.

Data
Configure consecutive data by combining the MEMOBUS/Modbus register address (test code in case of a loopback test) and the data the register contains. The data length changes depending on the command details.
A drive MEMOBUS/Modbus register always has a data length of two bytes. Therefore data written into drive registers must also always have a length of two bytes. Register data read out from the drive will always consist of two bytes.
u
Error Check
The drive uses a CRC-16 (cyclic redundancy check, checksum method) for checking data validity. Use the procedure described below when calculating the CRC-16 checksum for command data or when verifying response data.
n
Command Data
When the drive receives data, it calculates the CRC-16 checksum from the data and compares it to the CRC-16 value received within the message. Both must match before a command is processed.
An initial value of FFFFH (i.e., all 16 bits equal 1) must be used for CRC-16 calculations for the MEMOBUS/Modbus protocol.
Calculate the CRC-16 checksum using the following steps:
• The starting value is FFFFH.
• Perform an XOR operation of this value and the slave address.
• Right shift the result.
• When the overflow bit of the shift operation becomes 1, perform an XOR operation of the result from step 3 above and the fix value A001H.
• Repeat steps 3 and 4 until eight shift operations have been performed.
• After eight shift operations, perform an XOR operation with the result and the next data in the message (function code, register address, data). Continue with steps 3 to 5 until the last data has been processed.
• The result of the last shift or XOR operation is the checksum.

Writing to Multiple Registers
Function code 10h allows the user to write multiple drive MEMOBUS/Modbus registers with one message. This process works similar to reading registers, i.e., the address of the first register that is to be written and the data quantity must be set in the command message. The data to be written must be consecutive so that the register addresses are in order, starting from the specified address in the command message. The data order must be high byte, then lower byte.
The following table shows an example of a message where a forward operation has been set with a frequency reference of
60.00 Hz for the slave 1 drive.
If parameter values are changed using the Write command, depending on the setting of H5-11, an Enter command will be necessary to activate the data or save them.

C.11 Enter Command
C.11 Enter Command
When writing parameters to the drive from the PLC using MEMOBUS/Modbus communication it depends on the setting of parameter H5-11 if an Enter command must be used to enable these parameters or not. This sections explains Enter commands.
u
Enter Command Types
The drive supports two types of Enter commands as shown in
. An Enter command is enabled by writing 0 to register number 0900H or 0910H. These registers can be written to only. An error will occur if the user attempts to read from these registers.
Register No.
0900H
Table C.6 Enter Command Types
Description
Writes data into the EEPROM (non-volatile memory) of the drive and enables the data in RAM at the same time. Parameter changes remain even if the power supply is cycled.
Writes data in the RAM only. Parameter changes are lost when the drive is shut off.
Note:
0910H
1. Because the EEPROM can be written to a maximum of 100,000 times, refrain from writing to the EEPROM too often. The Enter command registers are write-only. Consequently, if these registers are read, then the register address will be invalid (Error code: 02H).
An Enter command is not required if reference or broadcast data are sent to the drive.
2. Parameter data cannot be written to EEPROM during undervoltage, even using 0900H.
3. If undervoltage occurs when a making several parameter changes issued with a single ENTER command, the writing process may be aborted before all of the new changes have been written. Because all of the data has not yet been written, the EEPROM data error
“CPF06” will be displayed the next time power to the drive is cycled. To prevent this problem, wait approximately 5 seconds after issuing the ENTER command before shutting off drive power.

Upper/lower limit check
Error handling when setting multiple parameters
Upper/lower limit check takes the settings of related parameters into account.
Data is accepted even if one setting is invalid. The invalid setting will be discarded. No error message occurs.
The upper/lower limit of the changed parameter is checked only.
The default settings of related parameters are changed automatically.
Error occurs if only one setting is invalid. All data sent are discarded.

Slave Not Responding
In the following situations, the slave drive will ignore the command message sent from the master, and not send a response message:
• When a communications error (overrun, framing, parity or CRC-16) is detected in the command message.
• When the slave address in the command message and the slave address in the drive do not match (remember to set the slave address for the drive using H5-01).
• When the gap between two blocks (8 bit) of a message exceeds 24 bits.
• When the command message data length is invalid.
Note:
If the slave address specified in the command message is 00H, all slaves execute the write function, but do not return response messages to the master.

<1> Codes refer to a set of three crimp terminals and three insulation caps. Prepare input and output wiring using two sets for each connection.
Example: Models with 14 AWG for both input and output require one set for input terminals and one set for output terminals, so the user should order two sets of [100-066-218].
Note:
Consider the amount of voltage drop when selecting wire gauges. Increase the wire gauge when the voltage drop is greater than 2% of motor rated voltage. Ensure the wire gauge is suitable for the terminal block. Use the following formula to calculate the amount of voltage drop:
Line drop voltage (V) = 3 × wire resistance (Ω/km) × wire length (m) × current (A) × 10

CSA for Industrial Control Equipment
The drive is CSA-certified as Industrial Control Equipment Class 3211.
Specifically, the drive is certified to: CAN/CSA C22.2 No. 04-04 and CAN/CSA C22.2 No.14-05.

Drive Motor Overload Protection
Set parameter E2-01 (motor rated current) to the appropriate value to enable motor overload protection. The internal motor overload protection is UL listed and in accordance with the NEC and CEC.
n
E2-01: Motor Rated Current
Setting Range: Model Dependent
Default Setting: Model Dependent
Parameter E2-01 (motor rated current) protects the motor if parameter L1-01 is not set to 0 (default is 1, standard induction motor protection enabled).
n
L1-01: Motor Overload Protection Selection
The drive has an electronic overload protection function (oL1) based on time, output current and output frequency, which protects the motor from overheating. The electronic thermal overload function is UL-recognized, so it does not require an external thermal overload relay for single motor operation.
This parameter selects the motor overload curve used according to the type of motor applied.
Disable the electronic overload protection (L1-01 = 0: Disabled) and wire each motor with its own motor thermal overload when connecting the drive to more than one motor for simultaneous operation.
Enable the motor overload protection (L1-01 = “1”, “2”, or “3”) when connecting the drive to a single motor unless there is another means of preventing motor thermal overload. The electronic thermal overload function causes an oL1 fault, which shuts off the output of the drive and prevents additional overheating of the motor. The motor temperature is continually calculated as long as the drive is powered up.
n
L1-02: Motor Overload Protection Time
Setting Range: 0.1 to 5.0 Minutes
Factory Default: 1.0 Minutes
The L1-02 parameter sets the allowed operation time before the oL1 fault occurs when the drive is running at 60 Hz and 150% of the full load amp rating (E2-01) of the motor. Adjusting the value of L1-02 can shift the set of oL1 curves up the Y-axis of the diagram below but will not change the shape of the curves.

Safe Disable Function Description
The Safe Disable function can be utilized to perform a safe stop according to the IEC/EN 61800-5-2, stop category 0
(Uncontrolled stop by power removal). It is designed to meet the requirements of the ISO/EN 13849-1, Safety Category 3, PL d, and IEC/EN 61508, SIL2.
Removing the voltage from terminal H1 disables the drive output, i.e. the power supply to the motor is cut by stopping the switching of the output transistors in a safe way. “Hbb” is shown on the display. Safe Disable is applicable for induction and permanent magnet motors.
u
Installation
If the Safe Disable function is utilized, the wire link between the terminals HC and H1 that is installed at shipment must be removed entirely.
Connect the drive to an ISO/EN 13849-1, Safety Category 3 interrupting device so that in case of a Safe Disable request the connection between the terminals HC and H1 is opened.

Installation Precautions
• To ensure the Safe Disable function appropriately fulfills the safety requirements of the application, a thorough risk assessment for the safety system must be carried out.
• The drive must be installed in an enclosure with a protection degree of at least IP54 in order to maintain ISO/EN 13849-1, safety category 3 compliance.
• If the safety device and the drive are installed in separate cabinets, install the Safe Disable wires in a manner preventing short circuits.

D.3 UL and CSA Standards
• The Safe Disable function does not cut the power supply to the drive and does not provide electrical isolation. Before any installation or maintenance work is done, the power supply of the drive must be switched off.
• Consider the following when using PM motors: When the Safe Disable function is active, a failure in two of the drive power devices can occur and current will continue to flow through the motor winding. This failure will not produce torque in an induction motor, however, when occurring in a PM motor, torque will be produced and cause an alignment of the rotor magnets, which may cause the rotor to turn up to 180 degrees electrically. Ensure that this possible failure mode is not safetycritical for the application.
• The wiring distance for the Safe Disable inputs should not exceed 30 m.
• The time from opening the Safe Disable input until the drive output is switched off is less than 1 ms.

Drive Motor Overload Protection
Set parameter E2-01 (motor rated current) to the appropriate value to enable motor overload protection. The internal motor overload protection is UL listed and in accordance with the NEC and CEC.
n
E2-01: Motor Rated Current
Setting Range: Model Dependent
Default Setting: Model Dependent
Parameter E2-01 (motor rated current) protects the motor if parameter L1-01 is not set to 0 (default is 1, standard induction motor protection enabled).
If Auto-Tuning has been performed successfully, the motor data that was entered in T1-04 is automatically written into parameter E2-01. If Auto-Tuning has not been performed, manually enter the correct motor rated current in parameter E2-01.
n
L1-01: Motor Overload Protection Selection
The drive has an electronic overload protection function (oL1) based on time, output current and output frequency, which protects the motor from overheating. The electronic thermal overload function is UL-recognized, so it does not require an external thermal overload relay for single motor operation.
This parameter selects the motor overload curve used according to the type of motor applied.

Drive Duty Motor with a Speed Range of 1:10
Vector Motor with a Speed Range of 1:100
Standard Fan-Cooled Motor (50 Hz)
Set L1-01 to 0 to disable the electronic overload protection and wire each motor with its own motor thermal overload when connecting the drive to more than one motor for simultaneous operation.
Set L1-01 to 1, 2, or 3 to enable the motor overload protection when connecting the drive to a single motor unless there is another means of preventing motor thermal overload. The electronic thermal overload function will cause an oL1 fault and shut off the output of the drive and prevent further overheating of the motor. The motor temperature is continually calculated while the drive is powered up.
n
L1-02: Motor Overload Protection Time
Setting Range: 0.1 to 5.0 Minutes
Factory Default: 1.0 Minutes
The L1-02 parameter sets the allowed operation time before the oL1 fault occurs when the drive is running at 60 Hz and 150% of the full load amp rating (E2-01) of the motor. Adjusting the value of L1-02 can shift the set of oL1 curves up the Y-axis of the diagram below but will not change the shape of the curves.
