The at-speed signal on my inverter (the infamous Huanyang), stays false when the spindle-on signal is false. Ergo, a simple connection to the motion component would inhibit jogging unless the spindle is running. If I want to utilize a wait-for-spindle function, I guess I'll need to cobble up some logic so that the signal is forced active unless a spindle-on command is in place.
