Thank you for your quick feedback, it is very much appreciated.
The motors are connected to the Duet 3 Tool Distribution Board which is powered directly by the 48v power supply, they are therefore energized as soon as I turn on the electrical cabinet (red M23CL LED flashes), I checked the voltage of the cable power supply of the motor, I am at 48v permanently.
The motors are equipped with a brake, I noticed that the brake is 24V, wouldn't it be a problem to power the motors with 48V?
The fuse blew when I engaged the motors (M17 Y X), releasing the brake.
Could switching on the motors create an overvoltage and blow the fuse?
Thank you very much for your help.
