As an aside, I'm reasonably sure it's a BOSS 3 because your 7 segment display has too few digits. A BOSS 4/5/6 has a 3 digit display and a 5 digit display, whereas I can see from the picture, you only have a 5 digit display. See http://www.centroidcnc.com/bridgeport_boss.htm for a picture of a BOSS 5 pendant with the larger display. I think the heatsinks on the steppers also tell you that it's a 3, but I don't know that for certain. > > Anyway, I've got some Parker OEM650 stepper drives on hand and would like to > use those for my retrofit, but they will only accommodate phase inductances > of 1 - 10 mH.

I can't answer this one with certainty, but the G203V tolerates 1-50 mH and it works well with the steppers on my BOSS. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
