Chapter 9 TROUBLE SHOOTING GUIDE
GT 112-E
AL025
Encoder internal error
Clearing Method Turn OFF the power supply and restart the servo drive.
Potential Cause Checking Method Corrective Actions
The internal memory
of the encoder is in
error. An encoder
counter error
occurs. 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.
AL026 Encoder data error
Clearing Method Turn OFF the power supply and restart the servo drive.
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.
