Will your controller be told ahead of time what the arbitrary point is, so that it can plan for that and start to slow down as it approaches? Does the 0.1" precision (accuracy?) apply to this arbitrary point?
Or will the controller need to respond to a "change now!" command given at an arbitrary point in time? In which case, how much overshoot is acceptable?
You can provide a lot more detail without revealing the specific application. The more detail you provide, the more likely you will get useful help.
