Deviation Limit of PID Control
】
F3009 PID1 deviation limit value
F3109 PID2 deviation limit value
The function to make a positive/negative limit for the deviation of command value and feedback value in PID control.
● Upper frequency limit: For frequency of F1007, the rate set by F3009/F3109 will be used as the limit value.
· F3009/F3109=0: no limit
· F3009/F3109=1
-
100%: Use the rate to upper frequency limit for control.
Example) When F1007=50Hz and F3009=20%, ±10Hz will be used to control the deviation of PID1 control.

PID Operation Polarity Switching
】
F3011 PID1 operation polarity switching
F3111 PID2 operation polarity switching
The function to switch the deviation operation results of command value and feedback value in PID control.
● For PID deviation of Fe, the polarity will be switched according to the settings of F3011/F3111.
· F3011/F3111=1: command value – feedback value.
The polarity of deviation Fe will not be changed.
· F3011/F3111=2: feedback value – command value.
The symbol of deviation Fe will be reversed. (Polarity reversion)
