Inverter Fault Notification
If a fault is detected in the Inverter, the SI-T/V7 stores the alarm or warning code in the
MECHATROLINK-II ALARM command and simultaneously turns ON the relevant bit in
the STATUS field.
The following table shows the alarm codes for SI-T/V7 notification if a fault is detected in
the Inverter.
