Mach cannot do 'continuous motion' of a position-controlled axis.
Hopefully your servo should have two modes of operation, speed control and position control, and a way to switch between them.
Just use a custom M code to switch between the two modes and control each in the normal manner. You will also have to consider indexing/orienting the motor if you switch between the modes more than once on a part.
A servo that I know for a fact has this ability is the Mitsubishi MR J2 series. It might be instructive to download a manual for this and compare with your one.
