could you please be a bit more specific with this request? Is this related to motion control with NI hard- or software? Are you looking for a way to control the drive via analog signals? In this case you should contact the drive's manufacturer to provide this information.
It is necessary to replace system CNC. Old communicated with servo amplifier on fibre-optic cable. New by means of signal TTL of a level. I would be grateful for any information on drives Socasin ST1 of a series.
