Hi,  
does anybody know what’s the UR5 joints’ working voltage and current range? Is the maximum voltage the joints can draw 48V? What is the maximum temperature of the joint motor before it’s overheated?

Thank you.

So you’re talking about the actual motor and not the controller board? My guess is 48V is maximum, as you say, to simplify the electronics, but it’s just a guess.

Maximum joint temperature is 85 degrees, where the robot will shut itself down.
