parameter P1-57 is
reached after a period
of time set by
parameter P1-58.
U, V, W, GND wiring error

when performing encoder wiring.
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.
Checking Method
1. Check if P1-57 is enabled.
2. Check if the setting values of P1-57
and P1-58 are both too small.
Checking Method
Check if wiring connections of U, V, and
W are not correct.
Check if the ground connection is loose
and ensure the ground is conducting
properly.
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.
Corrective Actions
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.
Corrective Actions
1. Set P1-57 to 0.
2. Correctly set P1-57 and P1-
58. Please note that the over-
low setting may results in
malfunction, but over-high
setting may let the motor
protection function not
operate.
Corrective Actions
Follow the wiring steps in the
user manual to reconnect the
wiring and ground the servo
drive and motor properly.
