Motor issues can arise from a number of reasons:

• Damaged cables leading to circuit breaks or short circuits
• Damaged connectors or water ingress in connectors
• Bad connection in connectors
• Damaged gears
• Overheated motor

Always troubleshoot the motor from the Manual screen. Run it at least 5 seconds in each direction. Press the “i” button for a detailed view. If the robot gives an alarm, check the troubleshooting guide for that specific alarm.

• Does the position counter change? If not, check the pulse signal and power cables.
• Does the function move physically? If not:
  • Does any sound come from the motor? If it does, the function could be physically stuck or the gear can be damaged. No sound? Check cables
  • Does the motor draw any current? If not, check the cables.
• Check that the emergency stop button is not pressed down
• Spray connectors with 5-56 or WD-40
• If you have access to a spare motor you can connect it temporarily to the connector in order to troubleshoot the function. Remember to ground it properly, e.g. by holding a motor metal part against robot chassie
