I’m controlling two NEMA 34 6A stepper motors through HSS86 stepper motor drivers. The drivers take AC and DC, between 20 and 80v. I’m using them to control a golf cart via remote control, and I wanted to use the golf cart’s battery pack to power the steppers (4 12v lead acid batteries in series: 48v). Is there any sort of current regulation I need in between the batteries and driver? I was planning on putting a 9A fuse between each driver and the batteries, but anything beyond that?

• (1) You asked: “Is there any sort of current regulation I need in between the batteries and driver?” My short answer is “NO”. Your driver is an advanced microstepping driver which has over current protection and fault alarm features.
