(4) If the MC in the main circuit power is switched OFF, the
fault output signal is not switched ON. When the MC is
OFF, the operation panel and parameter unit (FR-
DU07, FR-PU07) can be operated. (The motor cannot
be run)
1.4.3 Switching the inverter output MC ON/OFF (U, V, W)
Switch the magnetic contactor between the inverter and
motor only when both the inverter and motor are at a stop.
When the magnetic contactor is turned ON while the
inverter is operating, overcurrent protection of the inverter

*1 MC switch-ON might become available by selecting an appropriate inverter capacity. (For example, select an inverter capacity
considering the start current of the motor. Refer to page 476.)
*2 Because overcurrent protection and electronic thermal protection may occur at an inverter start, use of automatic restart after
instantaneous power failure/flying start (refer to page 367) is recommended.
