10.6 Alarm and Warning Codes for Inverter
There are the following four types of inverter alarms and warnings for different detection loca-
tions and error contents.
* SI-ET3: MECHATROLINK Option Card for Inverter
Note: 1. If more than one error is detected at the same time, the SI-ET3 gives priority to the error with the lowest
alarm code.
2. When an error is detected while another is being detected, the alarm code will not be refreshed.
3. If more than one minor failure (warning) is detected at the same time, the SI-ET3 gives priority to the error
with the lowest warning code number.
Inverter alarms and warnings are described below.
