Inverter fault and alarm indications

When the inverter detects a fault, depending on the nature of the fault, the operation panel
displays an error message or warning, or a protective function activates to trip the inverter.
●
When any fault occurs, take an appropriate corrective action, then reset the inverter, and resume
the operation.
Restarting the operation without a reset may break or damage the inverter.
●
When a protective function activates, note the following points.
●
Inverter fault or alarm indications are categorized as below.

Description
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.
