Mits M80 Rigid Tapping

I have a Hardinge V1000 VMC with Mitsubishi M80 controller. I want to rigid tap.

Not sure what code I need to specify to activate rigid tapping on this machine. My dealer is not very helpful.

What needs to change in the code below? It is only the tapping portion of the program shown.

My post (and experience) is for Fanuc. M29 turns on Rigid tapping in Fanuc. My code looks like this:

Any help or suggestions are appreciated.
