Alarm Description
1. Internal communication error of the
absolute encoder
2. Internal error of other type of
encoder
Encoder temperature exceeds the
protective range.
Excessive Deviation of Full Closed-loop
Position Control.
Linear scale communication is cut off.
The analog voltage is over than the
setting value of P1-83.
When the servo drive function
overloads, it might bring the abnormality
of motion control, such as PR or E-Cam.
The setting of E-gear ratio exceeds the
range (1/50~25600). Thus, when cycling
power on the servo drive, an alarm
occurs.
Due to battery undervoltage 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.
Encoder temperature exceeds the
warning level. (But it is still within the
protective range.)
The sequence is wrong when reading
the absolute position via DIO.
Incremental motor is not allowed to
activate the absolute function.
