If it is like a Barrafaldi or a Duplomatic I can help......I have installed both of these.......It looks alot like them and I would assume they use the same kind of encoder. Reading the encoder is fairly easy using ladder, If you happen to have FAPT Ladder III editing software I can send you what I wrote for this. I installed a Duplomatic turret on a Fanuc 21i TB controlled lathe about 6 months ago. Alot of these turrets are built and operate pretty much the same. I can get you the time and operation sequence if you need it. Timing on these turrets is critical. Control (including propagation delay) should be very accurate to +- 10ms or it will mis-index. What questions do you have?
