Alarm Description
Charging circuit of the servo drive is not removed and
the battery voltage is higher than the specification
(>3.8 V) or the encoder signal is in error.
Absolute position is in error.
Due to battery under voltage or the failure of power
supply, the encoder lost the internal record.
The voltage of the absolute encoder is lower than the
specification
The multi-turn of absolute encoder exceeds the
maximum range: -32768 ~ +32767
The sequence is wrong when reading the absolute
position via DIO.
Incremental motor is not allowed to activate the
absolute function.
Feedback position counter overflows.
