When the inverter starts, PID output is fixed at PID initial value(E2.23), and then
continuous for the PID initial value hold time(E2.24), at last PID begins operation of the
closed-loop adjustment.
The figure is functional schematic of PID initial value.
This function is used to limit the deviation between two PID output beats(2ms/beats), in
order to suppress the too fast changes of PID output so that stabilizing the inverter operation.

E2.25 and E2.26 respectively corresponds to the maximum of the absolute value of
output deviation when rotating forward and reverse.

Used to select whether to continue computing in the state of PID shutdown. Generally,
PID will stop computing in the state of shutdown.
