So there's no standard which outlines a proper policy that I know of for handling buss power to servo controllers through a safety circuit. Most modern Servo Controllers have some sort of safe torque off terminal or safety ethernet for stopping a drive, but for years now I have made it a standard practice to run the buss power of my servo controllers through 2 redundant force guided relays in series controlled by the appropriate safety circuit before landing them on the servo controllers.
Does anyone have a similar practice or an argument to support or repeal this practice? Is the Safe Torque Off terminals (or equivalent) good enough?
Thoughts appreciated.
