Revision June 2010
Checking Method
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.

Chapter 10 Troubleshooting
Corrective Actions
1. Please connect the
grounding (green color) of
U, V, W terminal to the
heatsink 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.
