Hello Thank you for your videos. Relying on your experience, I have a question about danfoss fc302 cranes liebherr. The driver works for 2 days without any problems. Sometimes the free stop passes and the load is released. The driver came to our workshop for repair. We suspected the control card. When you replace the control board, the panel freezes, but it displays an internal fault error (A38). power card does not recognize the control card. This is the mco 351 card with drivers with liebherr cranes application. How to solve this problem should be followed. THANK YOU.
