Long time reader, first time poster. I have been running a 3 axis desktop mill using Animatics Smart Motors (emulating stepper motors) for 12 months now. But as the smart motors are only emulating steppers, I have been thinking about converting them to operate as servo motors. They have inbuilt rotary encoders that can be connected to the out pins and velocity/direction can be supplied to an input as a 5V analogue signal. My current plan is use a Mesa 7I43-U-4 to read the encoders and supply the PWM signals (convert the PWM into analogue signal). Is this a feasible/sensible way to go?
I must admit that I am struggling to understand exactly how to configure EMC2 to achieve this. Am I correct in assuming that the PID will output a velocity/direction signal to the motor until the encoder counts = the new positional counts. Also, the velocity will decrease as it gets closer to the desired position?
