340 or 320 with large motor

[johnd]

I have a mill equipped with westamp servomotors which are rated 90 volts 6 amps. Can I use the 340 or 320 drive with these motors as long as the power supply is below the maximum voltage of the drive? What would that voltage range be? The motors are on a large vertical mill. I am not looking for speed.
Thank You

Yes I would use a power supply that is about 70 to 80 VDC and about 15A. I build quite a few systems and prefer the G320 over the G340. If your pc, program and mechanism paraemters match up then the G320 is cheaper and in my opinion less prone to problems with the direction change timing.
