Name
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).
Sets P-control proportional gain
as a percentage.
P-control is not performed when
the setting is 0.00.
Sets I-control integral time in 1-
second units.
I-control is not performed when
the setting is 0.0.
Sets the I-control limit as a per-
centage of the maximum output
frequency.
Sets D-control derivative time in
1-second units.
D-control is not performed when
the setting is 0.00.
Sets the limit after PID-control
as a percentage of the maximum
output frequency.
Sets the offset after PID-control
as a percentage of the maximum
output frequency.
Sets the time constant for low
pass filter for PID-control out-
puts in 1-second units.
Not usually necessary to set.
Select forward/reverse for PID
output.
0: PID output is forward.
1: PID output is reverse
(highlights the output code)
Sets output gain.
0: 0 limit when PID output is
negative.
1: Reverses when PID output is
negative.
0 limit when reverse prohibit is
selected using b1-04.
