Cause and
correction
Assumed cause Correction Prevention
Noise into the encoder cable • Separate the motor cable and
the encoder cable if they are
bundled together.
• Connect the shield to FG.
• Check that the motor ground
wire is connected to FG.
• Separate the motor cable and
the encoder cable if they are
bundled together.
• Connect the shield to FG.
• Check that the motor ground
wire is connected to FG.
Contact failure of the signal line,
and disconnection of the encoder
Replace the encoder cable if it is
broken. Firmly connect the
encoder connector to the Servo
Drive.
Confirm that the encoder is not
broken before use, and connect
the encoder connector to the
Servo Drive securely.
Power supply undervoltage to the
encoder
Use the recommended encoder
cable.
Use the recommended encoder
cable.
Encoder failure If this event occurs again after you
performed all corrections shown
above, replace the motor.
