Hi!
I want to replace existing CNC from Sodick ( www.sodick.com ), based on Windows95 and PMAC2-PC ISA as driver board from DeltaTau to
EMC + some driver board. The CNC verical center has name Sodick MC450 (vintage 1999).
I have 3 axes + 1 spindel + arm + turret for 20 tools. Hence 6 (six) servo drivers are using now.
What board I need to use? I don't want to use PMAC2 from DeltaTau. Is ther any more cheaper board?
DeltaTau has G compilator in its own build in memory. EMC software use its own G-code compiler.
The main problem - connect 6 servo drivers + number of I/O to interconnect with tool's turret.
Any advices?

Do your drives take velocity inputs +-10vdc? Do your servos have encoder feedback?

Yes, I use standart servo motor/servo driver with +-10V ADC

We also can use frequency-pulse driver control (like step motor) with encoder feedback.
Our servo driver can operate in both mode (+-10V and Freq/Pulse control).
The number of pulses per one round may be programmed from 200 till 4000 steps.
