Alarm Description
The absolute origin coordinate has not
been created. 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 causing the loss of
absolute position.
Command is not completed when the
barcode is written to the encoder.
When the encoder is powered by the
servo drive: the speed is over 8,800 rpm
or the acceleration is over 1×10
when the encoder is powered by the
battery: the speed is over 10,000 rpm or
the acceleration is over 4×10
An error occurs when the encoder is
reading data from or writing data to
EEPROM.
Absolute encoder single turn position
error.
Absolute encoder position error.
Encoder internal error (internal
computing error).
The encoder is not cycled after the
parameter is written, so the parameter
value is not updated.
Loss of the encoder Z pulse position.
Encoder memory is busy.
The command to clear the absolute
position is issued when the motor speed
is over 200 rpm.
AL07C occurs and is not cleared before
the power is cycled on the servo drive,
and then the motor stops operating.
