I've rescued a couple of gigantic Superior Electric steppers type M112-FF-401 rated at 950oz/in, (200steps per turn) with their PDM155 Modulynx drivers. I've Googled hi and low and found that they are well obsolete items. The were working perfectly in the robotics machines they came from.
My thoughts are whether they are worth being put to work to drive my wee TongYang ZAY7032G (HR 42827) mill drill in a sort of CNC project (like everyone else has already done).
As i'm an electronics man i'll need to sort out how to 'talk' to the PDM155s but if the steppers are BIG and heavy.
Appreciate any suggestions. Thanks Pete
