Do you have a link to any info on the controller or drives?

The dspmc controller does not "convert step/dir" to analogue. The motor/servo setup does not rely upon the clock cycle of Mach3 step pulses.

Thanks for the replys
The costs mount up verry fast in the servo area.
$500 pluss just for the boards , I dont realy see why they have to be so much more than large stepper systems.
So you're using 24vdc relays to transfer the limit switches back to the computer
and modbus out to the plc for communicating pulse and direction?
I'm incredibly familiar with Automation Direct as we have been going through a progressive process of eliminating AB PLCs and replacing them with various series from AD. And I'm also familiar with AC servo drives for more classic industrial solutions, so matched sets are my friend anyways.
Do you happen to have any good resources for breakout boards that you like and make integrating relatively easy?
And other than that do you have drives and motors that you particularly like?
Oh and as a side note, you use the PLC to communicate to the 24vdc to the drive, but your pulse and direction runs through your line driver into the master encoder input?Step/Dir goes from computer to SmoothStepper (Via USB) to PMDX 122 breakout then line drivers then drive.
