I have a sub spindle, live tool lathe. I really need rigid tap on the lives for many reasons. through research, I have found that the spindle drive for the lives does have the "OR" card/interface. It would require a 1000 line encoder installed in the spindle motor and the encoder data sent back to the OR board. this data is then ran through a ADC and the digital data is sent back to the control. No biggy hooking that up but getting the Seicos III to recognize the extra input and getting the proper parameters turned on to make use of the new data is a different story.

At this time, it just uses a mag sensor as a tach for that spindle. Any tech info on the III would be great. I am hoping I can simply change some settings around to enable this without needing new hardware/software.

The other 2 spindles do have the OR cards hooked up indicating they have closed loop vector operation.
