controller. Set as a percentage
(%) of maximum frequency.

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.
