This parameter is used to set the limit of the deviation between reference and
feedback value. When the difference is within the defined 'PID deadband', PID
control stops to bring a stable output.

Run
When the PID output reaches [E0.09] 'Output frequency high limit' or [E0.10]
'Output frequency low limit' in PID control, following modes are available for PID
regulation:
●
0: Stop integral regulation when frequency arrives at upper / lower limit
When the difference between the reference values and the feedback values
changes, the integral value follows immediately the difference. When the set-
ting frequency reaches the limits, the integration stops, and the integral value
remains unchanged.
This mode is used in applications with fast change reference values.
●
1: Continue integral regulation when frequency arrives at upper / lower limit
When the PID output reaches the limits, the integral continues up to its possi-
ble numerical limit.
This mode is used in applications with stable reference values. When the dif-
ference between reference and feedback changes, more time is needed to
eliminate the impact of accumulated integral regulation before the integral
value can follow the change in the trend.
