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

2：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.
