becomes 100%, a 100% correction will be issued in 1 sec. Decreasing H52 value, the
correction will be quickly, but a too low value could create a system instability.

H53: Derivative time is calculated by multiplying the difference between the feedback
variable instant value and the feedback variable value Derivative function operates only on the
error variation (i.e. if the error is constant this function does not operate) The error is detected
by 0.01 sec in Sinus M. If differential time is set to 0.01 sec and the percentage variation of
error per 1 sec is 100%, 1% per 10msec is output.

I17 ~ I24: To exchange PID to normal operation, set one of P1-P8 terminal to 21 and turn ON.

rPM: Calculates the feedback from H50 into Motor frequency and displays it.

rEF: Indicates PID controller’s command value.

Fbk: Converts feedback amount set in H50 to motor frequency.
