An encoder error has occurred at terminal X9, typically due to an interrupted encoder cable or pin X9/8 not being connected. This can lead to incorrect or no position feedback.

• Open circuit or damaged conductor in the encoder feedback cable connected to terminal X9.
• Pin X9/8 (typically encoder power supply return or ground) is not connected or has a high resistance connection.
• Incorrect encoder wiring to terminal X9 (e.g., swapped A/B signals, missing power supply, shield fault).
• Faulty encoder sensor (e.g., mechanical damage, internal electronics failure) providing no or intermittent signals.
• Loose or corroded connections at the encoder connector, terminal X9 on the drive, or intermediate junction boxes.
• Insufficient or excessive encoder supply voltage (e.g., 5V or 24V) provided by the drive or external supply.

1. 1

   1. Power down and lockout the drive. Disconnect the encoder cable from terminal X9 on the drive and at the encoder end.

2. 2

   2. Using a multimeter, check continuity of each individual wire in the encoder cable, paying special attention to the conductor for pin X9/8.

3. 3

   3. Verify the encoder supply voltage (e.g., 5VDC or 24VDC) present at terminal X9/7 and X9/8 with reference to ground, when the drive is powered on (motor disconnected).

4. 4

   4. Inspect terminal X9 on the drive and the encoder connector for bent pins, corrosion, or loose connections.

5. 5

   5. Ensure the encoder cable shield is properly connected to the drive's designated ground terminal (PE) at X9 and the encoder housing.
