This function is used to limit the deviation between two PID outputs (2 ms per PID output) to
suppress the rapid change of PID output and stabilize the running of the inverter.

☆
Integral separated
If it is valid, the PID integral operation stops when the DI allocated with function 38 "PID integral
pause" is ON.
If it is invalid, integral separated remains invalid no matter whether the DI allocated with function
38 "PID integral pause" is ON or not.
Stop integration when output reaches the limit
If "Stop integrtion" is selected, the PID integral operation stops, which may help to reduce the
PID overshoot.
