Setting range
0.00% ~ 100.00%
PA-24
Reverse maximum value between
two output deviation
Factory default
1.00%
Setting range
0.00% ~ 100.00%
This function is used to limit the difference between PID output two bats (2ms/bat), so as to against PID
output changing too fast, make the inverter run stably.
PA-23 and PA-24 correspond to the maximum of the output deviation absolute value when forward and
reverse, respectively.

Integration separation:
If integration separation is valid, when multifunctional digital DI integration pause (function 22) is valid, PID
integration stop calculating, PID is only valid when proportional and differential action.
When integration separation is invalid, whatever multifunctional digital DI is valid or not, integration
separation is invalid.
Stop integrating or not after output reach limit:
After PID calculation output reaches the maximum or minimum, whether stop integral action or not can be
selected. If the selection is stop integrating, PID integration will stop calculating, which may help to reduce
PID overshoot.
