value
PID through the target signal (command) and the controlled amount of the difference between the feedback
signal proportional (P), integral (I) and differential (D) operation, adjust the inverter output frequency, etc., to achieve
closed-loop system, the controlled amount Stable at the target value.
VFD500 built-in process PID structure as shown below, suitable for flow control, pressure control, temperature
control and tension control applications.
