：
automatic switchover based on deviation
The absolute value of PID command and
feedback deviation is less than P40.24, using
KP1, TI1, TD1; the absolute value of
deviation is greater than P40.25, using KP2,
TI2, TD2 parameters; the absolute value of
deviation is between P40.24~P40.25, The
two sets of parameters are linearly
transitioned.

This function is only valid when P40.39 = 0 which is not calculated. The PID output is reset after the inverter stops. If
P40.28
≠ 0, when the inverter runs, the PID output is equal to the initial value of PID and keeps the time of P40.28.
