 When the power phase-loss occurs and it exceeds the level (Pr.11-09) and the detection
time(Pr.11-07), it will execute the phase-loss protection(Pr.06-02). The AC motor drive
will record the operation time during phase-loss in Pr.11-29.
 If it is set to 0 or a larger number, it will short the life of rectifier and capacitors in the
AC motor drive.
