Set Value Control Method
1
PID output becomes the Inverter output frequency, and D control is used in the 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
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.
