Position command to the driver, and position feedback form the driver is all I need. maybe current velocity. and some sort of enable stuff. Alternatively only velocity command, if the feedback loop is closed via linuxcnc using linear feedback. PWM is cared for by the STM, currently I support DC servos, and AC sync servos. async is coming soon. As feedback resolvers and incremental encoders. linuxcnc does not need to know about the type of drive or feedback.
