Tool changers, Pallet changers etc typically use a raft of I/O, and the same with the degree of logic required to program.
It is possible the Linear scales were the only feedback to the controller, IIRC the 2000 did not have dual feed back capability?
The Servo/spindle drives are very likely analogue, as this was typical for these M/C's.
Rigid tapping requires the use of a spindle encoder, which you should already have.
If indeed the loop is closed back to the controller, then it should be possible to use non-intelligent drives, such as you have, but the analogue control would be a bonus as the majority of older machines use these or any of the new torque mode drives that would do the job.

Anybody out there can tell me the complexity of this retrofit. I am aware of all the toolchanger issues, pallet changer, ridgid tapping, but will it be such a hassle to hook these up? This machine has d.c. servos and linear scales but I cant seem to find encoders on the servos. It has Siemens drivers and Siemens dc spindle drive, are these analog. Has anybody ever done this?
