Parameter Description
Starting Segment Determines which segment will be the first for data transfer. If a value
greater than 128 (maximum number of segments allowed) is entered, an
Error
message results. If a value greater than the Ending Segment value
is entered, an
Error
message will be displayed.
Ending Segment
Determines which row in the ballscrew compensation table will be the last
to receive data from the laser file. If the segment limit on the table for the
axis is exceeded, data will not be entered beyond the limit.
Axis
Determines to which axis data will be applied.
Action
Three types of actions during data load can occur:
•
Replacing the existing data in the table
•
Adding to the existing data
•
Data is averaged with the existing data
Overwrite
will clear any values in the table beyond the segment limit for
the axis.

only replace the old values.
Action
enables
the user to fine-tune ballscrew compensation values from multiple passes
of laser readings.
Filename:
Enter the DOS filename of the laser file, including the path, if different
from the default.
Laser File Data File Format
Reference machine constant parameter:
MC_3072: Edit Ballscrew Table
.
The laser file data must be in the following format for the File Loader
Utility:
n1,
n2
where:
n1
is the commanded position
,
is the delimiter
n2
is the actual position as measured by the laser
Most laser data files have header information, which should be removed.
An example of an acceptable file format is as follows:
0 ,-1.05300568384907E-03
-1 ,-1.00202340866009
-2 ,-2.00227380774995
