  • Page 77: Pid Functions: Pa.00-Pa.28

    4.12 PID functions: PA.00-PA.28 PID control is a general process control method. By performing proportional, integral and differential operations on the difference between the feedback signal and the target signal, it adjusts the output frequency and constitutes a feedback system to stabilize the controlled counter around the target value. It is applied to process control such as flow control, pressure control and temperature control.
  • Page 78 When the feedback value is smaller than the PID setting, the inverter's output frequency rises. For example, the winding tension control requires forward PID action. 1: Reverse action When the feedback value is smaller than the PID setting, the inverter's output frequency reduces. For example, the unwinding tension control requires reverse PID action.
