Alarm Description

Communication of CN5 (encoder) is
breakdown
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 re-
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.
The possible causes might be:
1. The motor is used for the first time
2. The battery had run dry but has
replaced a new one.
Servo drive has not completely writing
barcode into encoder or the encoder
does not complete the command issued
by servo drive.
