I can't tell you much about your motors,but I have a '79 Mori sl3a,with Fanuc motors,that I'm retring with a Centroid.They want to know all about these,and I'm having trouble identifying them to the dealer.The x axis is a type 5n-2000m,which fanuc says"what?" to..The z axis is a type 10 t2000m,and I get the same response from them...I need to know current,voltage and stall.Any help on this?Thanks!Also am looking for a freq drive to power the 13 horse spindle motor.
