Set Value Control Method
1
PID output becomes the Inverter output frequency, and D control is used in the deviation (difference between PID target value and
feedback value.)
2 PID output becomes the Inverter output frequency, and D control is used in the PID feedback value.
3
PID output is added as compensation value of the Inverter output frequency, and D control is used in the deviation (difference
between PID target value and feedback value).
4 PID output is added as compensation value of the Inverter output frequency, and D control is used in the PID feedback value.
