PID Control Methods
There are four PID control methods. Select the method by setting constant b5-01.
Set Value
PID output becomes the Inverter output frequency, and D control is used in the difference between PID
1
target value and feedback value.
2 PID output becomes the Inverter output frequency, and D control is used in the PID feedback value.
PID output is added as compensation value of the Inverter output frequency, and D control is used in the
3
difference between PID target value and feedback value.
PID output is added as compensation value of the Inverter output frequency, and D control is used in the
4
PID feedback value.
