I think I'd have the gear number output as a number or an array of bits with at most one active, and leave it to something external to make the change happen. >It needs the hysteresis as the speed override will cause a gear range >change.

I'd add a min_speed for each gear, and then maybe have a couple of selection modes: highest torque mode = use the lowest gear for the selected speed highest speed mode = use the highest gear for the selected speed least changes mode = never change unless you really need to. There could even be a tolerance that allows the spindle to go at a slightly wrong speed if it prevents a gear change.
