5–9 OCI Data Server CNC Commands
Publication 8520-6.6 - August 1999
DELETE_ALL_AXISCAL_POINTS (no argument)
Use this command to delete all axis calibration points from the axis
calibration table. After execution of this command the control will
clear any data previously entered in the axis calibration table (all
processes).
For example:
[DELETE_ALL_AXISCAL_POINTS]
deletes all axis calibration points currently stored in the axis
calibration table for all axes.
DELETE_AXISCAL_POINT (axis_num, axis_cal_point)
Use this command to delete an axis calibration point. The axis_num
argument for this command identifies which logical axis number to
modify. The axis_cal_point argument identifies the specific point to
be deleted. Both arguments for this command are integers (DINT).
For example:
[DELETE_AXISCAL_POINT(1,6)]
deletes the sixth calibration point for the first axis in the process
configured in AMP.
ENTER_AXISCAL_MODIFY_MODE (no argument)
When this command is executed the axis calibration tables are
opened for editing. You must successfully issue this command
before attempting to modify the axis calibration tables.
For example:
[ENTER_AXISCAL_MODIFY_MODE]
opens the axis calibration table for editing and allows access to the
axis calibration data.
