Question #: 15216

Question: [Mach3 USB Interface Board] Can the 24VDC supply used for the interface board be the same supply used for stepper drivers, or do you need separate power supplies? If not, does GND and DCM need to be isolated?

Current Solution

I would recommend using a separate 24VDC power supply for the controller. The 24VDC that is connected to the controller is used for delicate input signals and output signals that control external devices. To keep interference and possible current and voltage fluctuations at a minimum due to the motor load, a separate power supply would be best.
