Checking Method
1. Check if the motor is well
grounded.
2. Check if the encoder cable is
separated from the power
supply or any high-current cable
to avoid interference.
3. Check if the encoder uses
shielded cable.
4. Check the motor speed.

Corrective Actions
1. Make sure the UVW connector
is grounded to the heat sink of
the servo drive.
2. Make sure the encoder signal
cable is separated from the
power supply or any high-
current cable.
3. Use shielded cable for the
encoder.
4. Make sure the motor speed is
within the rated range.
5. If the issue persists, please
send your servo drive back to
the distributor or contact Delta.
