Common Alarms & Troubleshooting

• Alarm 41x (Servo Error): Check 5V/24V power, encoder cable, or board damage.

• Positioning Deviation: Verify encoder signals, connector seating, or replace board.

• Servo Not Ready: Check power supply, interlock signals, or board fuses.

• Communication Failure: Reconnect servo bus cable or check board interface.

Installation & ESD Precautions

1. Power OFF the machine and wait ≥5 minutes for discharge.

2. Use an anti‑static wrist strap and ESD‑safe work area.

3. Align the board with the servo drive slot, insert firmly, and secure screws.

4. Reconnect encoder and power cables; ensure all connectors are locked.

5. Power on and test servo positioning, speed, and homing functions.

Maintenance

• Clean dust from the board surface periodically.

• Check connectors for tightness and corrosion.

• Inspect fuses and component signs of overheating.
