A81nx help

Hey guys I have a Makino a81nx that we are running a program on. We are machining while turning the b axis and we need it to rotate around clockwise. Currently every time we try to run this program the pallet starts rotating counter clockwise we have tried putting a negative number in place of the positive b move, however this did not help. Wasn’t sure if there was a specific m code or g code to force the pallet to rotate clockwise. Thanks in advanced!
