====== Problem with motor ======

===== Description =====

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

===== Troubleshooting =====

Always troubleshoot the motor from the [[:user_manuals:screens#manual_screen|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:alarm:ts_alarm|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
