Yaskawa iQpump Simplex Cheat Sheet

Simplex Cheat Sheet
To make sure you received the correct model, it is
essential to verify the iQpump nameplate with your order
and make sure that the iQpump has the correct rating so it
can be used with your motor. Please check the nameplate
information as shown in the example below.

Check that the available power will meet the input
power requirements.
·
Ensure that the output power from the iQpump is
compatible with the pump motor requirements.
In the case of systems with more than one iQpump,
follow the above procedure for each iQpump and pump
motor.
·
Mounting the iQpump
The mounting of the iQpump is extremely important
regarding environment and accessibility. Depending on your
system, there are various models available and the mounting
dimensions (footprint) may be different. Because the
mounting procedure is fairly extensive, it is beyond the scope
of this document; the user is referred to the iQpump User
Manual (Document No. TM.iQp.01) received with the
iQpump, Section 1 Physical Installation. Match the model
that you received and follow the procedure described in the
manual to ensure a safe and functional installation. In cases
where the system has more than one iQpump, refer to the
proper clearances required for adequate ventilation. Please
pay particular attention to:
·
The clearances to be maintained around the enclosure
for adequate ventilation.
·
The environmental specifications, such as avoiding
excessive dampness, extreme temperatures, chemical
exposure, corrosive areas, etc., to avoid damage to the
equipment and to maintain safety.
DANGER, LETHAL VOLTAGES ARE PRESENT- Before
The iQpump is DEFAULT SETUP TO START/STOP FROM THE
KEYPAD (digital operator). If this is the preferred start/stop
method, then continue to the feedback signal connection section.
Please refer to the wiring diagram below to start/stop the iQpump
using an external switch or contact.
! applying power to the iQpump, ensure that the
terminal cover is fastened and all wiring connections
are secure. After the power has been turned OFF, wait
at least five minutes until the charge indicator
extinguishes completely before touching any wiring,
circuit boards or components.

LOW/HIGH FEEDBACK LEVEL DETECTION
iQpump continuously monitors the system feedback signal. To display a „Low Feedback‟ fault set the low feedback
level parameter P1-07 to the minimum feedback level allowed for your system and to display a „High Feedback‟
fault set the high feedback level parameter P1-09 to the maximum feedback level allowed.

PRE-CHARGE OPERATION
This function is used when the pump system requires to be pre-charged before normal operation. Upon start, the
iQpump will run at a fixed speed for a specified time or until the feedback signal reaches a programmed level, after
which it will switch to auto mode operation.

Sets the frequency reference used when the pre-charge function is active.
Sets the maximum allowed pre-charge time. A value of 0 disables this function.
Thrust Bearing Acceleration Time
Sets the thrust bearing acceleration time. When enabled (P4-05>0), the iQpump output frequency will ramp up to
the specified thrust bearing frequency reference in P4-05 using an acceleration time as specified in P4-04. The PI
mode is automatically disabled. Once the output frequency reaches the programmed thrust bearing frequency, the
iQpump automatically switches to PI control and the original acceleration time (C1-01), and will continue in the
normal operation (auto) mode, unless Pre-Charge is enabled, in which case Pre-Charge mode occurs. This
function active in the Hand Mode and Auto Mode.
Note: In Auto Mode, the Minimum Pump Frequency (P1-06) will become the thrust bearing frequency if smaller
than the thrust bearing frequency in P4-05. In Hand Mode, the minimum frequency is P4-05 when the thrust mode
is enabled. The Pre-Charge level is not active in the Hand Mode.
Thrust Bearing Frequency
Sets the frequency reference used when the thrust bearing function is active. A value of 0 disables this function.
Thrust Bearing Deceleration Time
This deceleration time will be used to bring the iQpump from Thrust Frequency (P4-05) to stop when Thrust Mode
is active. Any time the Run Command is removed while the iQpump is operating in the Thrust Mode above the
Thrust Frequency, this deceleration time will be used once the frequency reference is at or below the Thrust
Frequency. Note: In Auto Mode, the Minimum Pump Frequency (P1-06) will become the thrust bearing frequency
if smaller than the thrust bearing frequency in P4-05. In Hand Mode, the minimum frequency is P4-05 when the
thrust mode is enabled. The Pre-Charge level is not active in the Hand Mode.

The iQpump will initiate a “High Feedback Fault (HFB)” when the feedback level rises above the programmed
level for a time specified in P1-10. The iQpump will coast to a stop when a fault occurs. This function is active
during running in all operation modes.
Sets the level when the iQpump will run at the pre-charge frequency (P4-02). The iQpump will stop when one of
the following conditions occurs: Feedback signal rises above P4-01 level, pre-charge timer P4-03 expires, or low
water digital input is deactivated (H1-XX = 85). The pre-charge function can only be activated while in a stop
condition. The function is enabled by setting P4-03 to a value greater than 0. When the function is activated, the
iQpump operator display indicates a “Pre-charge” alarm. Note: This function is only active in the stopped mode.
Thrust Mode: The pre-charge level is used when the thrust mode is active for the feedback check. The thrust
mode is deactivated when the feedback exceeds the programmed level in P4-01. A value of 0 disables the thrust
mode feedback check function.

and the specified set-point exceeds this level for the time specified in parameter P1-12. Example: 30 PSI
difference, set-point 100 PSI, measured is 65 PSI due to a broken pipe in the system.

AUTO OPERATION – POWER DOWN STORAGE
Allows iQpump to automatically start after power failure when operated from keypad/digital operator. This function is
recommended for use when operating the iQpump in remote/unmanned areas.
Recommended for use when Start/Stop
command is from keypad.
(See illustration 5)
When the iQpump is powered down while running, an internal run
command will automatically be initiated upon power-up.
Simplex Cheat Sheet
Pump Rotation and Feedback Signal Check
6
When Quick Setup is completed, press
MONITOR
to exit the Pump Quick Setup menu
and go to operation.
In this step, the pump motor is checked for proper direction and operation. This test is to
be performed solely from the digital operator. Apply power to the iQpump after all the
electrical connections have been made and the terminal cover has been reattached. At
this point, DO NOT RUN THE MOTOR, the Digital Operator should display as shown
below in Fig. 5.
Step
Auto Mode Operation
7
iQpump can be operated in automatic mode when the following actions have been
performed:
· All parameters are programmed
· Pump motor direction has been checked
· Feedback signal has been checked
At this point, DO NOT RUN THE MOTOR, the Digital Operator should display as shown
below in Fig. 6.
Hand Mode speed can be adjusted with parameter P5-02 ‘Hand Reference’
in the Pump Quick Setup (recommended setting is 45.0 Hz for initial
startup).
After the system has been in operation, confirm that the sleep function operates
satisfactory by closing off the discharge valve. The motor speed
(U1-02) will decrease and the iQpump will go to sleep when U1-02 falls below the
sleep level (P2-02) for the sleep time specified (P2-03).
If iQpump does not go to sleep after the valve has been closed, check U1-02 to
determine the no-flow speed (Hz) and adjust the sleep level (P2-02) to ensure
the motor speed drops below this level. It is recommended to set the sleep level
(P2-02) 2 Hz above the no-flow speed (Hz). After confirmation that the sleep and
wake up function operate correctly, set the minimum pump frequency
(P1-06) to 1 Hz below the sleep level (P2-02).

Next, press the AUTO
button to start the
iQpump.
If the direction is not correct, then power down the iQpump.
! DANGER, LETHAL VOLTAGES ARE PRESENT- Before applying power to the
iQpump, ensure that the terminal cover is fastened and all wiring connections
are secure. After the power has been turned OFF, wait at least five minutes until
the charge indicator extinguishes completely before touching any wiring, circuit
boards or components.
Using Safety precaution, and referring to Fig. 1 or 2, swap any two of the three output
leads to the motor (U/T1, V/T2 and W/T3). After the wiring change, repeat Step 6 and
recheck motor direction.
iQpump automatically starts in Auto Mode when the feedback signal level falls below
the programmed level in parameter P1-04 for the specified time in P1-05.
