• When the motor is running, once the driving power is interrupted, the output voltage will not be
output instantly. When the power is recovered, if P.57=9999, the inverter will not restart
automatically, and if P.57=0.1~5, the motor coasts for a while (the set value of P.57), then the
inverter will restart the motor automatically.
• Once the motor was automatically restarted, the output frequency of the inverter is the target
frequency, but the output voltage is zero. Then the voltage will be increased gradually to the
expected voltage value. The period for voltage increasing is called ‘restart voltage rising time
(P.58)’.
• There are 4 digits in P.150, every digit have the different meaning, relevant positions as following:
