Encoder data error
Potential Cause
Checking Method
Corrective Actions
An encoder data error
occurs for three times.
1. Check if the servo motor is properly
grounded.
2. Check if the encoder signal cables are
placed in separate conduits from the
cables connected to R, S, T and U, V,
W terminals to prevent the
interference.
3. Check if the shielded cables are used
when performing encoder wiring.
1. Please connect the grounding
(green color) of U, V, W
terminal to the heat sink of the
servo drive.
2. Ensure that the encoder
signal cables are placed in
separate conduits from the
cables connected to R, S, T
and U, V, W terminals to
prevent the interference.
3. Please use shielded cables
for Encoder wiring.
4. If the error does not clear
after all the above actions are
done, please contact your
distributor for assistance or
contact with Delta.

Motor internal error
Potential Cause
Checking Method
Corrective Actions
The setting value of the
encoder is in error.
1. Check if the servo motor is properly
grounded.
2. Check if the encoder signal cables are
placed in separate conduits from the
cables connected to R, S, T and U, V,
W terminals to prevent the
interference.
3. Check if the shielded cables are used
when performing encoder wiring.
1. Please connect the grounding
(green color) of U, V, W
terminal to the heat sink of
the servo drive.
2. Ensure that the encoder
signal cables are placed in
separate conduits from the
cables connected to R, S, T
and U, V, W terminals to
prevent the interference.
3. Please use shielded cables
for Encoder wiring.
4. If the error does not clear
after all the above actions are
done, please contact your
distributor for assistance or
contact with Delta.
