Output frequency

The integral/derivative amount of PID control can be reset with an external signal. Assign function

number "52: PID differential/integral reset" to an input terminal.

<F366: PID1 differential gain>

This parameter adjusts the differential gain level of PID control. This gain increases the speed

of response to a rapid change in deviation (difference between the set value and the feedback

value). Note that setting the gain beyond necessity may cause fluctuations in output frequency,

and thus operation to become unstable.

Feedback value

The integral/derivative amount of PID control can be reset with an external signal. Assign "52:

PID differential/integral reset" to an input terminal.

4) Adjusting feedback input

Make adjustment by converting input level of the feedback value into frequency. Refer to [6. 6.
