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
• Damaged gears

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.

• 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
