Goodrive3000 series medium voltage VFD
Function
Name
code
Select PID feedback channel by the parameter.
Note: The reference channel and feedback channel cannot coincide; otherwise, PID cannot control
effectively.
2, 3, 5 and 6 can be used only after inserting corresponding extension cards.

P09.03 PID output feature
Select PID output feature.
0: PID output is positive. When the feedback signal exceeds the PID reference, the output frequency of
the VFD will decrease to balance PID. For example, rewind the strain PID control.
1: PID output is negative. When the feedback signal exceeds the PID reference, the output frequency of
the VFD will increase to balance PID. For example, unwind the strain PID control.

Proportional gain
P09.04
(Kp)
The function is applicable to the proportional gain P of PID input.
P determines the strength of the whole PID adjuster. Larger P, stronger the adjustment. The parameter of
100 means that when the offset of PID feedback and reference value is 100%, the adjusting range of PID
adjuster is the maximum frequency (ignoring integral and differential function).
