Task
9.1
NOTICE: Setting value
may cause PID control loop
instability if misadjusted.
9.2
NOTE: Disable parameter
b5-12 if a transducer is not
installed.
9.3 Adjust depending on
system performance
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.
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)

Speed
Description/Menu Access
Sets the integral time for the PID controller.
Decrease integral time to make
iQpumpMicro more responsive.
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
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.
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.
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
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)
