Sets the integral time for the PID controller.
Decrease integral time to make iQpumpMicro more responsive. NOTICE: Setting value may cause

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
NOTE: Disable parameter
b5-12 if a transducer is not installed.

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.

See Note
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.

- Loss of Prime
- Pump Over Cycle.
Refer to L5 parameter group. The number of restart attempts is set by L5-01.
P1-06 40.0 Hz
Minimum
Pump
Speed
Minimum frequency at which the drive will run. Applies to both HAND and AUTO modes.
Example: Base pump motor speed is 3600 RPM, minimum speed is 2400 RPM. Set minimum pump fre-
quency to 40.0 Hz. (2400 ÷ 3600 x 60 Hz=40Hz)
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)
P1-06 should be set to the level at
which the pump produces minimum
pressure even at zero flow.
P2-03 5 sec.
Sleep Delay
Time Sets the delay time before the drive enters Sleep Mode when the selected signal level (P2-01) falls be-
low the specified sleep level (P2-02). Adjust according to system
requirements.
P4-12 30.0 Hz
Thrust
Bearing
Frequency Sets the frequency reference used when the thrust bearing function is active.
The drive will accelerate to this frequency in the time set to P4-11. The drive will decelerate from the
frequency in the time set to P4-13.
Primarily used for submersible
pumps. Program P4-12 = 0.0 Hz to
disable function when iQpumpMicro is
used with a centrifugal pump.
P4-17 0.2 Min
Utility Start
Delay
Sets the amount of time that the drive will delay starting if a Run command is present at power-up.
When P1-01, Pump Mode, is set to 3 (MEMOBUS network), the drive is unavailable to the network
(Pump Off Network) when the function is active.
Setting this parameter to 0.0 disables the function.
The iQpump Micro waits the time specified in P4-11 before auto operation becomes active when utility
power is restored and P4-10 is enabled (1).
Note: Only active when
P4-10 is enabled (1) and
operation (start/stop) is from the digi-
tal operator.
THRUST BEARING - SUBMERSIBLE MOTORS
The factory recommends using the T Thrust Bearing
function to prevent excess motor wear when uusing
a submersible motor in combination with the
iQpump Micro. Enter the minimum motor
frequency in parameter P4-11 to enable this
function. E
Example: Minimum motor speed 1800
RPM, 1800 RPM ÷ 3600 RPM x 60.0 Hz = 330.0 Hz Output Frequency

LOW/HIGH FEEDBACK LEVEL DETECTION
AUTO OPERATION – POWER DOWN STORAGE 8
Allows the iQpump Micro to automatically start after power failure when operated from the digital operator. This
function is recommended when operating the iQpump Micro in remote/unmanned areas.
Use parameter P4-10 to enable this function.
WARNING! Stay Clear- Equipment starts automatically. An internal run command will
automatically occur on power-up if the iQpump Micro is powered down while running.
This function is used when the pump system requires a pre-charge before normal operation. Upon start the iQpump
Micro 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.

SETPOINT
SET-POINT NOT MET
P1-16 Setpoint-LOP Tim
The iQpump Micro can display a ‘Setpoint Not Met’ fault when the iQpump Micro is unable to maintain the
programmed system setpoint due a problem with the pump system. Set P1-15 to the maximum allowed difference
between setpoint and feedback level.
P1-15 Max Setpoint Diff
The iQpump Micro continuously monitors the system feedback signal. Set the low feedback level parameter P1-08
to the minimum feedback level allowed for your system to display a ‘Low Feedback’ fault. Set the high feedback
level parameter P1-11 to the maximum feedback level allowed to display a ‘High Feedback’ fault.
