Hi y'all, hope the holiday has been good for you.
I have a Haas Hrt6a I need to run on a VF5.

Having trouble entering the HRT6A number in settings mode, (4TH axis enable), When it is flashing 'NEW', I type in number, hit enter, get 'invalid number' message. Any hints? Does machine need a drive or configuration for 4th axis.
Thanks everybody
