Description
0: Disabled
1: Enabled (Deviation is D-
controlled.)
2: Enabled (Feedback value is D-
controlled.)
3: PID control enabled
(frequency reference + PID
output, D control of deviation)
4: PID control enabled
(frequency reference + PID
output, D control of feedback
value).
0: PID output is forward.
1: PID output is reverse
(highlights the output code)
0: 0 limit when PID output is
negative.
1: Reverses when PID output is
negative.
