Without knowing the driver chip, looks fine to me!

cnc2K,

It looks OK to me but I would lose the zeners across the windings. I designed that drive; it's big, black, heavy and full of epoxy right? It is the primative ancestor to the G201. The pin-out is the same.

thanks for the reply, can you take closer look on pin 7-pin12 on this diagram. http://www.xizou.com/images/driver.JPG
also, what is pin7 use for?

Yes, the driver and black, bag, and with epoxy on the back.

thanks for you help.

Best bet is to download our G201 manual and wire the OMS drive per the G201 user's manual. Same pinout, same current set resistor values, same everything. Just a much older version of what we make now.

for pin 7 i should connect it to ground or just leave it alone

How can i find out what size of resistor to use? i have 2 sets of stepper motor
1st set series 1.75amp and 2nd set series 3.3 amp?

i want to pull 5v out from my 24v power supply, i can use 5V Fixed-Voltage Regulator 7805? 5v is for 3 drivers.
