Well, I could use some help fellows! My slow motion Hardinge CHNC project just got speeded up with the demise of the spidle motor on my Pratt and Whitney lathe. What I have got is a stripped machine, the resolvers have been replaced with encoders on the X and Z axiis and new cables pulled through to the connection area on the back of the X axis.Both cables are shielded and drained 6 twisted pair for a total of 12 leads per cable. Questions:Can I run the axis encoder in the same cable as the turret encoder? The turret runs at 12Volts logic, will this cause any crosstalk? How did Hardinge do threading with a resolver on the spindle? I cannot find an index mechanism or any extra leads that would go to one. The spindle resolver is still in place but can be replaced easily with an encoder with index. The plan is to fit this all up with Pico Systems PWM controller which I have at hand and if needs be I have an extra Par port card for extra I/O. Ed.
