b5-71: PID Fdbk 1/2 Selection
No.
Name
(Hex.)
b5-71
PID Fdbk 1/2 Selection
(01E6)
0 : Feedback 1
The drive does D control on the difference between the feedback value and the PID setpoint output through U5-01
[PID Feedback].
1 : Feedback 2
The drive does D control on the difference between the feedback value and the PID setpoint output through U5-05
[PID Diff.Feedbk].
b5-72: PID D-FF Mode
No.
Name
(Hex.)
b5-72
PID D-FF Mode
(01E7)
0 : D=Fdback
The drive does D control on the feedback output through U5-06 [PID AdjustFeedback].
1 : D=FdFwd
The drive adds the frequency reference to the PID output. The drive does D control on the feedback output
through U5-06 [PID AdjustFeedback].
b5-02: Proportional Gain (P)
No.
Name
(Hex.)
b5-02
Proportional Gain (P)
(01A6)
RUN
Larger values decrease errors, but can cause oscillations. Smaller values let too much offset between the setpoint
and feedback.
Set b5-02 = 0.00 to disable P control.
b5-03: Integral Time (I)
No.
Name
(Hex.)
b5-03
Integral Time (I)
(01A7)
RUN
Set a short integral time in b5-03 to remove the offset more quickly. If the integral time is too short, overshoot or
oscillation can occur.
Set b5-03 = 0.00 to disable I control.
