That shouldn’t normally matter. I would be very surprised if the brake winging insulation wasn’t good for 24V. I think you should check the brake, make sure that it isn’t leaky. Does your electrician have an insulation tester? Is frame ground also a zero-volt reference for logic and field wiring? You sound to be using the terms semi-interchangeably. What is the brake switching device in the drive? _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
