Does Anyone know roll constant for WMW Niles ZSTZ630 C1 Gear Grinding machine or have manuals and willing to share?

I have ZSTZ500 , and the roll constant is 119.5372 , i tried using the same constant on ZSTZ630 , but the finished helix angle result after grinding helical gear was off by 30minute.

I wonder was it due to different roll constant or something else was wrong on my ZSTZ 630
