Reference
Decrease integral time to make iQpump more responsive.
Select what to do when the feedback device (transducer) fails or gets disconnected.
0: Disabled, continue running no message is displayed
1: Alarm, show warning on the keypad when the feedback device fails or is discon-
nected
2: Fault, stop pump system when the feedback fails or is disconnected
Time it takes to accelerate the pump motor from zero to maximum speed.
NOTE: Factory default with Thrust Mode enabled is 12.0 sec, 20.0 sec when dis-
abled.
Time it takes to decelerate the pump motor from maximum speed to zero.
NOTE: Factory default with Thrust Mode enabled is 5.0 sec, 10.0 sec when dis-
abled.
Determines the number of times iQpump will perform an automatic restart on the
faults listed in the comments column.
iQpump System Protection Faults that can be setup to restart are Low Level Feed-
back,
High Level Feedback, Transducer Loss, Not Maintaining Setpoint, Loss of Prime,
Pump Over Cycle. Refer to parameters P4-07 and P4-08. The number of restart at-
tempts is set by L5-01.
If the restart fails (or is not attempted due to a continuing fault condition) iQpump
waits the Maximum Restart Time After Fault, before attempting another restart.
Minimum speed (Hz) the pump motor has to operate at.
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 = 40 Hz)
Time it takes before the pump system goes to sleep when the selected signal level
(P2-01) falls below the specified sleep level (P2-02)
Sets the frequency reference used when the thrust bearing function is active. A
value of 0 disables this function.
When utility power is restored and P4-10 is enabled (1), iQpump waits the time
specified in P4-11 before auto operation becomes active.

Caution: can cause instability if
value is too low.
NOTE: Disable parameter b5-12

P1-06 should be set to the level
where the pump can produce the
minimum pressure even at zero
flow.
Adjust according to system
requirements.
Primarily used for submersible
pumps. Program P4-12 = 0.0 Hz
to disable function when iQpump is
used with a centrifugal pump.
Note: Only active when P4-10 is
enabled (1) and operation
(start/stop) is from the
digital operator.
