Module 9042 Reading The Spindle Coordinates (Format 0.001 Degrees) - HEIDENHAIN iTNC 530 Technical Manual

February 2002
Module 9042 Reading the spindle coordinates (format 0.001°)
The following coordinate values are saved in five successive double words
beginning with the specified target address:
n
Actual value
n
Nominal value
n
Actual value in reference system
n
Following error (servo lag)
n
Distance to go
The value for actual, nominal, and reference value are standardized at 0° to
+360.000°.
The values for servo lag and distance-to-go are displayed between –2879.912°
and +2879.912°. Format: 0.001°.
If MP3010 < 6 (no closed-loop spindle), then all coordinates are read as zero.
During operation under open-loop control (M03 / M04 active or M05 and open
position control loop), the nominal value is considered to be the actual value .
The following error and distance to go are considered to be zero.
