Hello Said,
the AM3044 has a PTC as temperature sensor. Maybe the sensor is not connected properly trough the connector X14/X24. So the resistance should be very high (measuring range from 400 to 2000 ohm).
You can check the recognized resistance in the Drive Manager. I assume you will see very high value.
You could also switch off the
temperature monitoring, but your motor is than not protected anymore if it is
too hot.
