4.7 Basic iQpump Setup and Application Preset Parameters
n b3-01: Speed Search Selection at Start
Determines if Speed Search is automatically performed when a Run command is issued.
No.
b3-01
Setting 0: Disabled
This setting starts operating the drive at the minimum output frequency when the Run command is entered. If external Speed
Search 1 or 2 is already enabled by a digital input, the drive will start operating with Speed Search.
Setting 1: Enabled
This setting performs Speed Search when the Run command is entered. The drive begins running the motor after Speed Search
is complete.
n b5-01: PID Function Setting
Enables and disables the PID operation and selects the PID operation mode.
No.
b5-01
Setting 0: PID disabled
Setting 1: Output frequency = PID output 1
The PID controller is enabled and the PID output builds the frequency reference. The PID input is D controlled.
n b5-02: Proportional Gain Setting (P)
Sets the P gain applied to the PID input. Larger values will tend to reduce the error but may cause oscillations if set too high,
while lower values may allow too much offset between the setpoint and feedback. The function of b5-02 is disabled when
P1-24 > 0.
No.
b5-02
n b5-03: Integral Time Setting (I)
Sets the time constant used to calculate the integral of the PID input. The shorter the integral time set to b5-03, the faster the
offset will be eliminated. If the integral time is set too short, however, overshoot or oscillation may occur. To turn off the
integral time, set b5-03 to 0.00.
No.
b5-03
n b5-09: PID Output Level Selection
Reverses the sign of the PID controller output signal. Normally a positive PID input (feedback smaller than setpoint) leads to
positive PID output.
