Cause
Serial communication protocol transfer
error between the encoder and evaluation
module.
The absolute encoder fault word supplies
fault bits that have been set.
The encoder sends a set error bit via the
serial protocol.
After initializing the pole position using
track C/D, Hall signals or pole position
identification routine, the zero mark was
detected outside the permissible range.
For distance-coded encoders, the test is
carried out after passing 2 zero marks.
Fine synchronization was not carried out.
The encoder functionality is not operating
correctly.
For a square-wave signal encoder (TTL,
bipolar, double ended), the A*, B*, and R*
signals are not inverted with respect to
signals A, B, and R.
The servo motor with an absolute encoder
is changed. Actual motor ID is different
from commissioned motor ID.
The motor connected with an absolute
encoder cannot be operated. The servo
drive in use does not support the Motor ID.
The servo drive in use does not support
encoderless operation.
Remedy
Check the encoder cable and shielding
•
connection.
Replace the motor.
•
Check the encoder cable connection, and
•
make sure the encoder cables are routed in
compliance with EMC.
Check the motor temperature.
•
Replace the encoder/motor.
•
Check the encoder cable and shielding
•
connection.
Replace the encoder/motor.
•
Check that the encoder cables are routed
•
in compliance with EMC.
Check the plug connections.
•
If the Hall sensor is used as an equivalent
•
for track C/D, check the connection.
Check the connection of track C or D.
•
Replace the encoder or encoder cable.
•
Check the encoder type used (incremental
•
or absolute) and encoder cable.
If relevant, note additional fault messages
•
that describe the fault in detail.
Check whether the encoder is connected at
•
the encoder port.
Check the encoder or cable for whether the
•
encoder supplies TTL signals and the as-
sociated inverted signals.
The servo motor will be automatically config-
ured after the acknowledgement of this fault.
Use a suitable motor.
Check the encoder cable connection be-
•
tween the servo drive and the servo motor.
Use a servo motor with encoder.
