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.
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.
2].
