Reading of axis
coordinates 7 7 7 7 Read the axis coordinates with Module 9040 or Module 9041.
The values are saved in double words beginning at the given address.
The values for all axes are read in, regardless of whether individual axes are
excluded through MP10. (TNC 426: 5 double words, TNC 430: 9 double
words). Values for excluded axes are undefined.
To define the coordinate value of an axis, the reference point of the axis must
first be traversed.
