PID Function
• This function enables process control of such elements as flow rate, air volume, and pressure.
• To use this function, set A071 to "01" or "02".
• You can disable the PID operation in progress using an external signal.
To use this function, allocate "23" (PID: PID disabled) to any of the multi-function inputs. While the
PID terminal is turned on, the Inverter disables the PID function and outputs normally.
• You can limit the PID output under various conditions.
