Setting
Description
Range
0: Disabled
1: Enabled (Deviation is D-
controlled.)
2: Enabled (Feedback value
is D-controlled.)
3: PID control enabled
(frequency reference + 0 to 4
PID output, D control of
deviation)
4: PID control enabled
(frequency reference +
PID output, D control of
feedback value).
Sets P-control proportional
0.00
gain.
P-control is not performed
25.00
when the setting is 0.00.
Sets I-control integral time.
0.0 to
I-control is not performed
360.0
when the setting is 0.0.
Sets the I-control limit as a
0.0 to
percentage of the maximum
100.0
output frequency.
Sets D-control differential
time 0.00 to
D-control is not performed 10.00
when the setting is 0.00.
Sets the limit after PID-con-
0.0 to
trol as a percentage of the
100.0
maximum output frequency.
Sets the offset after PID-con- -100.0
trol as a percentage of the
maximum output frequency. +100.0
Sets the time constant for low
pass filter for PID-control out- 0.00 to
put. 10.00
Usually not necessary to set.
Selects forward/reverse direc-
tion for PID output.
0 or 1
0: Normal PID output
1: Reverse PID output
0.0 to
Sets output gain.
25.0
0: Limit to 0 when PID
output is negative.
1: Reverses when PID output
is negative. 0 or 1
Limit to 0 is also active when
reverse prohibit is selected by
using b1-04.
