Alarm name

Absolute position is lost

Encoder undervoltage

Number of revolutions of the absolute encoder overflows (issued by encoder)

Wrong motor type

Encoder overspeed

Encoder memory error

Encoder single-turn absolute position is in error

Encoder absolute number of revolutions is in error

Encoder internal error

Encoder parameter setting incomplete
