Example
PID_Compact sampling time = 100 ms
PID algorithm sampling time = 1000 ms
Minimum ON time = 200 ms
Output is a constant 15%. The smallest pulse that PID_Compact can output is 20%. In the
first cycle, no pulse is output. In the second cycle, the pulse not output in the first cycle is
added to the pulse of the second cycle.

Minimum ON time
In order to minimize operation frequency and conserve the actuator, extend the minimum ON
and OFF times.
If you are using "Output" or "Output_PER", you must configure the value 0.0 for the minimum
ON and OFF times.
Note
The minimum ON and OFF times only affect the output parameter Output_PWM and are not
used for any pulse generators integrated in the CPU.
