Hi all,
Got a question from a friend, he has a new milling machine that requires three phase, he's got a three phase supply with three wires RED/YELLOW/BLUE
He has connected these color to color in the cabinet on the miller but the miller runs slowly. There is a fourth wire in the cabinet that has been cut off (BLACK), he has tried to earth this without any change in performance.
Any ideas how he can determine what is the problem?
Thx
