VS-626MR5 Alarm List
In the VS-626MR5, the protective functions operate according to the error
content when a fault and an error phenomenon are generated during a drive
operation when the drive is stopped. This error content is displayed on the
7 segment LED, according to alarm number.
Table 4.17: Alarm List
