Err29

• Fault cause: Drive motor open circuit, motor failure, or controller failure

  
  

  Troubleshooting Methods

  1. Open the stacker rear cover and check for damage to the wiring at the handlebar bracket. If damaged, repair the wiring.

  
  

  2. If no visible damage, measure the drive motor wiring resistance (should be 0.3-0.8Ω). Abnormal resistance suggests a motor or wiring issue—repair or replace as needed.

  
  

  3. Measure the controller end of the motor wiring (should also be 0.3-0.8Ω). Normal resistance indicates a controller fault—replace the controller.
