  2. Press and hold the learn run button (S401) 
  3. Plug the power supply connector back in (terminal X3).
  4. After a short initialization period the learn run starts automatically and you can release the run button (S401).
  5. When the 7-segment display shows "u", the learn run has been completed successfully.
  • Motor is not compatible with the door controller
  • Motor is defective and has to be replaced
 4Motor protection enabledMotor oscillates in one of the two end positions
Check whether the drive command "OPEN" or "CLOSE" is permanently present. For this you use the buttons on the door controller (press and hold the button).
  • If the door no longer oscillates, you must check the higher-level door PLC.
  • If the door continues to oscillate, then you must increase the profile parameter Continuous torque (power) CLOSE or "Continuous torque (power) OPEN" accordingly. You use the Service Tool for this. 


All the meanings of the 7-segment display are given in the controller manual, for example:
