1
Enabled: Deviation is subject to derivative control.
Forward
2
Enabled: Feedback signal is subject to derivative control.
3
Enabled: Frequency ref PID output, and devia-
tion are subject to derivative control.
4
Enabled: Frequency ref PID output, and feed-
back signal are subject to derivative control.
5
Enabled: Deviation is subject to derivative control.
Reverse
(Reverse the
PID output.)
6
Enabled: Feedback signal is subject to derivative control.
7
Enabled: Frequency ref PID output, and devia-
tion are subject to derivative control.
8
Enabled: Frequency ref PID output, and feed-
back signal are subject to derivative control.

Condition
Target
Value
The currently selected
frequency reference
Determined by the Frequency Reference
Selection (n004).
When local mode is selected, the target
value is determined by the Frequency Ref-
erence Selection in Local Mode (n008).
When multi-step speed references are se-
lected, the currently selected frequency
reference will be the target value.
Feedback
Value
The frequency reference
that is set in the PID
