I think you are asking about how to do spindle orient. Having used machines with vfd+pid orient and machines with mechanical orient and lock, I have to say the mechanical scheme wins, hands down. A full servo spindle would orient fine -- but if you don't have it, I suggest trying hard to come up with a mechanical orient stop, and use the "jog" feature of the vfd to get there. It should have a switch so when it's done the vfd can know to stop jogging.
