Hi,
I'm having a problem with a stepper motor lashup hopefully someday becoming a cnc mill. When I connect the power supply, a 36v 11A switched mode, as I increase the stepper speed through a dedicated stepper driver the voltage measured across the power supply (and the stepper driver) begin to rise towards the maximum allowed voltage of the driver. The motor is a nema 23 4nM motor. As far as I can tell I have all the dip switches in their correct positions for current and step.
Is there anything I can or need to do to correct this, as I would not want to damage an eighty pound driver?
Thanks
john
