When the frequency converter is started, only after PID output being fixed to be PID starter FA-21 and the
retention time of PID starter being FA-22, can PID start the closed-loop regulating operation. Fig 6-28
illustrates the function of PID starter.

This function is designed to restrict the difference value between the two beats of PID output (2ms/beat), so
as to prevent PID output from changing too fast and consequently stabilize the operation of the frequency
converter.
FA-23 represents the positive maximum absolute value of the output deviation while FA-24 represents its
reverse maximum absolute value.

Integral separation:
If integral separation is set to be valid, then PID integral will stop operating when multi-functional digital
DI integral stopps being valid temporarily, at which time only the proportion and differential function of
