The spindle is a servo drive from the ASDA-B2 400W series
It is controlled by the M3/M4 command - it works on the old machine and runs Mach2 software. (guided by step and direction)
Unfortunately, I do not have documentation of the planar circuits.
How to connect such a servo drive as a spindle to the axbbe board?
I am attaching sample photos of the documentation I found.
Could someone help me and draw a very simple drawing of how to connect it.
