Serial Servo Communication
(OP)
Is EtherCAT becoming the defacto standard for servo amplifier serial communication? Are the commands likely to be PWM, Phase command current or position? Aor all of the above?

RE: Serial Servo Communication
Usually the master downloads position the motion controller uses to construct a polynomial and then do fine interpolation between the master position. The motion controller can compute a fine position and velocity for each time between the master position. This method works well enough but there are flaws in this method if you want to get picky.
