KE300A Inverter Parameter Description
137
PA-09
PID deviation limit
Factory default
0.0%
Setting range
0.0% ~ 100.0%
When the deviation between PID given value and feedback value is smaller than PA-09, PID stops
adjustment. The output frequency is stable when the deviation is small, which is suitable for some close
loop control applications.
PA-10
PID differential amplitude
Factory default
0.10%
Setting range
0.00% ~ 100.00%
PA-11
PID given filter time
Factory default
0.00s
Setting range
0.00s ~ 650.00s
PID given filter time is the time that PID given value changes from 0.0% to 100.0%.
When PID given is changing, PID given value linearly changes according to the given filter time, so as to
reduce the adverse effect of the system caused by the given sudden change.
PA-12
PID feedback filter time
Factory default
0.00s
Setting range
0.00s ~ 60.00s
PA-13
PID output filter time
Factory default
0.00s
Setting range
0.00s ~ 60.00s
PA-12 is used to filter the PID feedback value, this filter can improve anti-interference capability of
feedback value, but will bring the response performance of the process close loop system down.
PA-13 is used to filter the PID output frequency, this filter will reduce the sudden change of the inverter
output frequency, but also will bring the response performance of the process close loop system down.
PA-14
Sampling period
Factory default
2
Setting range
0.00
～
65535
The sampling period of the feedback value is calculated once in each sampling period. The larger the
sampling period is, the slower the response is. The set value *2 (ms) is the sampling period.
