List of alarm display

When an alarm occurs in the inverter, the protective function is activated bringing the inverter to an alarm stop and
the PU display automatically changes to any of the following error (alarm) indications.
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 input side of the
• Alarm display............................................When the protective function is activated, the operation panel display
• Resetting method............................................When the protective function is activated, the inverter output is kept stopped.
• When the protective function is activated, take the corresponding corrective action, then reset the inverter, and
resume operation.
