Module 9041 Read axis coordinates (format 0.0001 mm)
Module 9041 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 1/10000 mm in double words beginning at the programmed target
address. The number of double words that are written to varies depending on
the configuration.
Condition:
Regardless of whether individual axes have been excluded through MP10,
the coordinate values are always loaded for all axes. The values for excluded
axes remain undefined.
The coordinate value of an axis remains undefined until the reference point
has been traversed.
In a tilted working plane, the axis coordinates are referenced to the non-
tilted coordinate system.
The tool length is ignored for the actual values in the datum system.
The coordinate type "Actual values in the datum system" must only be read
when the working plane is NOT tilted.
Distance counter in [mm]:
Updated once a minute if a change of at least 10 mm has occurred. The
maximum value of a counter corresponds to the value from MP4050.x and
is cleared with W1058/W1168 (resetting the accumulated distance).
