Fault output signal
Opening the magnetic contactor (MC) provided on the input side of the inverter at a fault
occurrence shuts off the control power to the inverter, therefore, the fault output will not
be retained.
Fault or alarm indication
When a protective function activates, the operation panel displays a fault indication.
Operation restart method
While a protective function is activated, the inverter output is kept shutoff. Reset the
inverter to restart the operation.
