Re: [CAD_CAM_EDM_DRO] Re: 7A, 80VDC 10 microstep drive

Tim,

That sounds great. One thing though, I have always been concerned about the
performance and speed of any driver that uses a 30 volt supply. I build cnc
routers and I need a driver that can drive my router at 200 to 400 inches
per minute.

My current system uses the Pacific Scientific 6410 drivers at 70 volts and
1/4 step. The current system that I am building will use the Sig Positec 3
phase motors with 1000 pules per rev. and 130 volts.
