HEIDENHAIN TNC 426 PB - Reading of Axis Coordinates

December 2001 Display and Operation 6 – 233
Reading of axis
coordinates
7
77
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.
Module 9040 Reading of axis coordinates (format 0.001 mm)
Call:
SEE MODULE 9041.
Module 9041 Reading of axis coordinates (format 0.0001 mm)
Call:
PS K/B/W/D <Target address Dxxxx>
PS K/B/W/D <Type of coordinate>
0: Actual values
1: Nominal values
2: Actual values in the reference system
3: Servo lag
4: Distance-to-go
5: Deflection (measuring touch probe)
6: Actual values in the shifted reference system (datum
shift)
7: Reference values with backlash compensation offset
from MP710.x
8: Temperature compensation from the description tables
of the titling-axis geometry
