10.5 Inverter Alarm and Warning Codes
Errors are classified by the following four types, according to where the error occurred and the error contents.
* SI-T refers to the MECHATROLINK option board.
When more than one error is detected at one time, the SI-T will report the alarms in order from the smallest alarm
code number.
When another error is detected while another is being detected, the alarm code will not be refreshed.
When more than one minor failure (warning) is detected at one time, the SI-T will report alarms in order from the
smallest warning code number.
Inverter alarms and warnings are described below.
