Hello
I am using Hyundai N700e inverter and control water pump with PID regulator, which is in inverter. But somebody could me explain, what means A77 settings parameter (PID Err Limit)? Maybe could give explain need to use this parameter. Thank for advise.

In my opinion, A77 is working as error limiter at the error output of PID controller. Error limiter is helpful to minimize overshoot/undershoot when a sudden high change is done on setpoint value. See the figure below.
