The notifications vary in consequence and required action.

make the drive stop and re-
quire reset of the drive.
Alarms
inform of unusual operating conditions but the drive will con-
tinue running.
Infos

For some faults you can program different responses in the application. See parameter group
Protections.
The fault can be reset with the
Reset button
on the control keypad or via the I/O terminal. The
faults are stored in the Fault history menu which can be browsed. The different fault codes you
