5 TROUBLESHOOTING
When an alarm (major failures) 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 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 display ........................................... 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.
(Refer to page 73.)
•
When the protective function is activated, take the corresponding corrective action, then reset the inverter, and
resume operation.
Not doing so may lead to the inverter fault and damage.
