Triac fanuc advice/project help

[Lone_Ranger]

The whole Fanuc AC servo setup eliminates any kind of drift, lag, brushes etc, the system uses encoders on the motors not tachos and the encoder signals are fed back directly to the Fanuc main board which gives a full closed loop system which is constantly monitored by the Fanuc, also all the velocity, acceleration and very importantly any backlash can be set/compensated for using the Fanuc Parameters.

I was referring to jpmiller's machine which is not Fanuc like the original posters - it's a DOS Denford machine with (SEM?) servo drives instead of steppers...
Updating that machine to Mach would make sense

Apologies, yes, you are correct, that would make sense to move away from the old control system to Mach3

Thanks admin as far as I'am aware my servo triac is a closed loop system the system also uses encoders? and the sem motors are ac?
but the control system is dsp 386 is this correct?

If it helps, here is the original record sheet for that machine:
