Our old 4VA could not rigid tap
We always had to use floating holders
& program the feed in units per minute, it couldn't do a G95
PS -- we couldn't even do ramping on an arc ( ie helix cutting a bore had to be done by point to point )
I have an older MC4VA with an OSP5000M-G controller. How do I know if I have rigid or sync tapping cycle? I have tried G284 but it errors on that. I am trying to run a large tap in and out twice and its off pitch on the second cycle...

If you don't have an encoder on the final spindle, then that points to not having the option.
