1998 mazak sqt-200msy t-plus control.

My problem is controling the sub speed. I am currently machining the part bring the sub up, pull part,then cut off. After i sync the main and sub (m502) and cut off i cancel(m505). The sub runs the last speed programed while in sync mode. I select teh sub(m300) after the cancel and program g97 m304(ss reverse) s2000, the sub will run speed of 1500. Does anyone know what i am missing here?
Thanks for your help
 
Got it

g112 g97 m304 s2000

i guess m304 (s.s. Reverse) is not enough for it. G112(output comand to opposite system) is needed to tell it the sub is in control
