It'll work just fine for most any position or velocity control app,

If there's no motion controller in the system and the goal is tight
speed regulation, then the tach feedback is useful.


By "controller", do you mean something other than this servo amp?
'Cause the amp doesn't have inputs for encoder feedback, just tach.
