Not neccesarilly, with Fanuc and some others, the option is in the control but not turned on unless paid for, also the spindle motor has to have feed back encoder on the spindle.

With the right inverter/VFD, a regular induction motor can be made suitable for rigid tapping, if a pulse generator is fitted to the motor and an encoder on the spindle shaft.
The method used is called electronic gearing, where the Z axis is electronically geared off the spindle encoder.
This is also required for helical milling.
The similar functions performed on a Lathe would be threading and CSF.
