The short answer is no because rigid tapping requires a spindle motor that has its encoder integrated with the axis controllers. in other words the spindle will rotate 1 revolution EXACTLY as the Z axis moves one pitch of the programmed thread. You coud try rigid tapping with a non-integrated spindle and you might be successful but I think you will break a few taps along the way.

However, if your control has in terms of "number of revolutions turned" then you might be able to do this thing in a macro if you can conrol very accurately the start and stop of the spindle and of the Z axis. You also will not be able to test it in single block as to be effective rigid tapping of one hole must be executed in one block by the control.
