Errors (Alarms)

3.1 Errors (Alarms)

If any fault has occurred in the inverter, the corresponding protective function is activated to bring the inverter to an alarm stop and automatically give the corresponding error (alarm) indication on the PU display.

If your fault does not correspond to any of the following errors or if you have any other problem, please contact your sales representative.

Retention of alarm output signal ..... When the magnetic contactor (MC) provided on

the power supply side of the inverter is opened at the activation of the protective function, the inverter's control power will be lost and the alarm output will not be held.

Alarm indication .............................. When the protective function is activated, the

operation panel display automatically switches to the above indication.

Resetting method............................ When the protective function is activated, the

inverter output is kept stopped. Unless reset, therefore, the inverter cannot restart. Switch power off once, then on again; or apply RES signal for more than 0.1s. If the RES signal is kept on, "Err." appears (flickers) to indicate that the inverter is in a reset status.

When the protective function is activated, take the appropriate corrective action, then reset the inverter, and resume operation.
