1. 1

   Inspect communication cables between the main controller and the Motor Controller (MC) for damage, loose connections, and proper seating at both ends.

2. 2

   Measure and verify the supply voltage to the Motor Controller (MC) at its input terminals against the specified nominal voltage range.

3. 3

   Verify communication bus termination and shielding (if applicable) according to the Kone documentation for the specific communication protocol.

4. 4

   Check and confirm communication parameters (e.g., baud rate, node ID, protocol settings) are correctly configured and match between the main controller and the Motor Controller (MC).

5. 5

   Observe communication status LEDs on the Motor Controller (MC) and the main controller for any error codes or unexpected behavior.
