【External PID Control】
The external PID control doesn't mean to use PID control output as the control for output frequency of the inverter, it means to use
inverter as an independent PID controller and use it to control the external peripheral devices.
The formation and action of each PID control is set and selected together with the normal PID control function of the inverter output
frequency.
Power supply
PID command
F3203 External PID control selection
F3204 External PID operation mode selection
● The function to select external PID actions.
· F3203=0: no external PID control
· F3203=1: PID1 external control is effective
· F3203=2: PID2 external control is effective
· F3203=3: For factory adjustment
· F3203=4: Both PID1 and PID2 external controls are effective
· F3203=5: For factory adjustment
· F3203=6: For factory adjustment
Matching to the selection of external PID, select the operation mode of external PID control. This function is used to decide the start
and stop of the external PID control.
● Select the operation mode of external PID control
· F3204=1: Operation interlocked with inverter operation
Start operation interlocked with inverter operation and start the external PID control. When the inverter is stopped, stop PID
control.
· F3204=2: PID output after power input
Start operation interlocked with inverter power supply and start the external PID control. When detecting the undervoltage
during inverter power supply OFF, stop the PID control.
· F3204=3: PID output controlled by external terminals
Start the operation of external PID control through the external multi-function terminal input (DI1~DI8).
PID1EX Signal
The terminal to operate or stop the PID1 control.
ON： Operate PID1 control
OFF： Stop PID1 control
PID2EX Signal
The terminal to operate or stop the PID2 control.
ON： Operate PID2 control
OFF： Stop PID2 control
Note 1: During external PID control, the PID component selection: F3205 is noneffective, it will not make an addition
calculation for the frequency command value of the inverter.
Note 2: During external PID control, stop PID control and reset/clear the operation results of PID control.
Note 3: When trying to stop the external PID control, please use PID control selection in inverter stoppage: F3203=0.
