File Loader Error Messages
The File Loader allows up to 128 table entries. If more than 128 entries
are loaded, the CNC displays the warning, “
Data from file truncated!
”
The message will appear following the data transfer.
Set the segment limit to the proper limit before you attempt the laser file
load.
Ensure that the segment length setting matches the displacements of the
laser readings. Otherwise, the ballscrew compensation table will contain
invalid data. The laser data provided above, for example, shows
displacements of one inch per segment. To avoid data error, the operator
must enter this value (1”) as the segment length before loading the laser
readings.
The positive/negative sign of the segment size during ballscrew
compensation file loading must match the direction of machine travel
used for the laser readings. This also applies to the laser values.
The zero value in the laser file can be positive or negative, regardless of
the direction of travel. Otherwise, a negative travel laser file must contain
all negative values (with the possible exception of the zero value). The
segment size must be negative as well. For positive travel, substitute
“positive” for “negative” in all cases.
