Since 4 compensation points are available for each machine data, it is specified in the control
that only the point on the far righthand side (bits 0, 1) can be defined as the reference point.
Example
• Reference point is to lie on compensation point 793
793 – 1
MD offset = ––––––––––= 198
4
• MD offset 198 = MD 6198
Value in MD 316* ... 198
As stated above, the reference point determines the compensation point at which leadscrew
error compensation is activated following reference point approach. No compensation is
allowed at this compensation point!
