Reading of axis

Read the axis coordinates with Module 9040 or Module 9041.

The values are saved in double words beginning at the given address. Enough

double words must be reserved. The number of required addresses is

according to the AXISNUMBER = entry in OEM.SYS. If this entry does not exist,

the number is according to the enabled control loops.

To define the coordinate value of an axis, the reference point of the axis must

first be traversed.

Module 9040 Read axis coordinates (format 0.001 mm)

Module 9040 reads the axis coordinates from the control loop for all NC axes.

Different values can be loaded: Actual value, nominal value, servo lag,

distance-to-go, the deflection of a triggering touch probe, temperature

compensation values, and the distance counter (counts the distance traveled

by an axis).

The datum system equals the reference system shifted by a datum

compensation. All values, except for the distance counter, are saved in the

format 1/1000 mm in double words beginning at the programmed target

address. The number of double words that are written to varies depending on

the configuration.
