Name Description
Default
value
Modify
feedback and reference by PID regulator. If
feedback changes by 100% during this period, the
regulation of differential regulator (ignoring integral
and differential actions) is Max. output frequency
(P00.03)
The longer the derivative time, the stronger the
regulation intensity.
Setting range: 0.00
–10.00s
P09.07
Sampling cycle
(T)
It means the sampling cycle of feedback. The
regulator operates once during each sampling
cycle. The larger the sampling cycle, the slower
the response.
Setting range: 0.001
–10.000s
0.001s

P09.08
Limit of PID
control deviation
It is the max. allowable deviation of PID system
output value relative to closed-loop reference
value. Within this limit, PID regulator stops
regulation. Set this function code properly to
regulate the precision and stability of PID system.
Setting range: 0.0

P09.09
Upper limit value
of PID output
These two function codes are used to set the
upper/lower limit value of PID regulator.
100.0% corresponds to Max. output frequency
(P00.03) or max. voltage (P04.31)

Feedback offline
detection value
Set PID feedback offline detection value, when the
detection value is no more than the feedback
offline detection value, and the duration exceeds
0.0%
