Task Parameter Name Description/Menu Access Default Value
9.1
NOTICE: Setting value
may cause PID control loop
instability if misadjusted.
b5-03 Integral Time Setting
(I)
Sets the integral time for the PID controller.
Decrease integral time to make
iQpumpMicro more responsive.
3.0 sec.
9.2
NOTE: Disable parameter
b5-12 if a transducer is not
installed.
b5-12 Feedback Loss
4 to 20 mA
Detection Selection
Performs a 4 to 20 mA wire break detection
on the analog input that is programmed for
PID feedback. Terminal TB1-1 A2 (typical)
0: Disabled, continue running, no message
is displayed
1: Alarm, display warning on the digital
operator when the feedback device fails or is
disconnected.
2: Fault, stop the pump system when the
feedback fails or is disconnected
3: Run at the setting value of parameter
b5-13
2 (Fault)
9.3 Adjust depending on
system performance
C1-01 Acceleration Time 1 Sets the time to accelerate the pump motor
from zero to maximum speed.
NOTE: The factory default with Thrust Mode
enabled is 12.0 sec, 20.0 sec when disabled.
20.0 sec.
See Note
C1-02 Deceleration Time 1 Sets the time to decelerate the pump motor
from maximum speed to zero.
NOTE: The factory default with Thrust Mode
enabled is 5.0 sec, 10.0 sec when disabled.
10.0 sec.
See Note
9.5 Refer to L5 parameter
group. The number of restart
attempts is set by L5-01.
Confi gurable iQpump Micro
System Protection Faults for
Auto-restart:
- Low Level Feedback
- High Level Feedback
- Transducer Loss
- Not Maintaining Setpoint
- Loss of Prime
- Pump Over Cycle.
L5-01 Number of Restart
Attempts
Sets the number of times the drive may
attempt to restart after these faults occur:
– oC-Overcurrent
– GF-Ground Fault
– LF-Output Phase Loss
– PF-Input Phase Loss
– oL2-iQpumpMicro Overload
– oL1-Motor Overload
– oL3/4-Overtorque
– DC Bus Fuse Blown
– Uv1-DC Bus Undervoltage
– ov-DC Bus Overvoltage
– oH1-Overheat

9.6 P1-06 should be set to
the level at which the pump
produces minimum pressure
even at zero fl ow.
Example: Base pump motor
speed is 3600 RPM, minimum
speed is 2400 RPM. Set
minimum pump frequency to
40.0 Hz. (2400 ÷ 3600 x 60
Hz=40Hz)
P1-06 Minimum Pump
Speed
Minimum frequency at which the drive
will run. Applies to both HAND and AUTO
modes.
NOTE: For minimum pump frequency, the
drive will use the highest setting from among
P1-06, P4-12 (Thrust Bearing Frequency), or
d2-02 (Reference Lower Limit)
40.0 Hz
