10.4 Servo Drive Alarm List for Absolute Function and
Monitoring Variables
Display Alarm Name Alarm Description
AL028
Encoder voltage error or
the internal of the
encoder is in error 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.
AL029 Gray code error Absolute position is in error.
AL034
Internal communication of
the encoder is in error
1. Internal communication error of the absolute encoder.
2. Internal error of other type of encoder.
AL060
The absolute position is
lost
Due to battery undervoltage or the failure of power supply,
the encoder lost the internal record.
AL061
Encoder under voltage
The voltage of the absolute encoder is lower than the
specification.
AL062
The multi-turn of absolute
encoder overflows
The multi-turn of absolute encoder exceeds the maximum
range: -32768 ~ +32767
AL069
Wrong motor type
Incremental motor is not allowed to activate the absolute
function.
AL289
Feedback position
counter overflows
Feedback position counter overflows.
