F41 Auto restart on momentary power loss. 000:
Enable
001:
Disable
F41=000: Auto restart after a momentary power loss is enabled on resumption of power and
applying the run signal, according to setting of parameter F4.
The Inverter will carry out an auto speed search, once the motor rotation speed is found then it will
accelerate to the running speed before the power loss.
F41=001: Disable.
F42 Auto restart times: 000 ~ 005
1.) F42=000: The inverter will not auto-restart on fault trip.
2.) F42>000
The Inverter will carry out an auto search 0.5 sec after the fault trip, and while the inverter output is
switched off and the motor is coasting to stop.
Once the rotation speed is determined the inverter will accelerate or decelerate to speed before the
fault.
3.) When OL1, OL2, OH, BB faults happens, Auto restart doesn’t work.
Note: Auto restart doesn’t work while DC injection braking or deceleration to stop
is
performed.
F43 Motor rated current (A)
F44 Motor rated voltage (Vac)
F45 Motor rated frequency (Hz)
F46 Motor rated power (KW)
F47 Motor rated speed (RPM) : F47 X 10= Motor rated speed
F48 Torque boost gain (Vector), C14=000
Performance: If the motor load is determined to be too large increase the output torque.
