I do have six-step brushless servo drives that can be run from my PWM controller, but they are not capable of driving the larger brushless motors to full peak torque. The first brushless drives used SIX PWM signals from the controller to EACH drive. I don't think they ever had an analog-input servo amp for the brushless motors.
There are some other drives from AMC and such that can deliver more current and take PWM input and Hall signals. My Fanuc converters (two models, for first-generation and later serial Fanuc encoders) will give the Hall signals.
