PID Function
Setting
This parameter determines the
function of the PID control.
0: Disabled
1: D= Feedback
2: D= Feed-Forward
3: Freq. Ref. + PID output
(D = Feedback)
4: Freq. Ref. + PID output
(D = Feed-Forward)

PID Offset
Adjustment
Sets the amount of offset of the
output of the PID controller. Set
as a percentage (%) of maximum
frequency.
The offset is summed with the
PID output. This can be used to
artificially kick-start a slow
starting PID loop.

Delay Time
Constant
Sets the amount of time for the
filter on the output of the PID
controller.
Note: The offset is summed with
the PID output. This can be used
to artifically kick-start a slow
starting PID loop.
Note: Normally , change is not
required.
