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.
•To switch between enable/disable via the terminal block (external signal), allocate 23 (PID enable/
disable) to the desired multi-function input. Select OFF for enable and ON for disable.
Basic Structure of PID Control (Example)
PID Enable/Disable
The PID enable/disable function disables the PID function temporarily through terminal input. This
overrides the A071 setting to control the motor frequency.
Parameter No.
