B.3.4 Trouble Shooting (Alarm Indications)

When an alarm occurrs in the inverter, the protective function is activated bringing the inverter to an
alarm stop and the monitor display automatically changes to any of the following alarm indications
(see Table B.3.4).

When the protective function is activated, take the corresponding corrective action (refer to factory),
then reset the inverter and resume operation. (See Reset VSD Section B.3.3)
