In other words, encoder position linked to motion.spindle-revs, but no input to motion.spindle-speed-in? I would imagine that it might be uncommon, but not unknown. For example a serial encoder might not have velocity data.
I think thats true with the HM2 SSI BISS and FANUC encoders Not sure if its possible but you might consider doing something like the PID component which detects if pid.N.feedback-deriv is connected and calculates a local d/dt velocity if not -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." ??
