or the compensation is invalid.
Backward
Error
The error generated by the motion towards decreasing direction of coordinate
value.
Forward Error
The error generated by the motion towards growing direction of coordinate value.
1. The style of writing of each axis error sequence:
[Axis Name]
<Nominal Machine Coordinate>, < Forward Error>, < Backward Error>
<Nominal Machine Coordinate>, < Forward Error >, < Backward Error >
<Nominal Machine Coordinate>, < Forward Error >, < Backward Error >
2. The sign of nominal machine coordinate and actual machine coordinate
Pay special attention to the sign of nominal machine coordinate and actual machine coordinate,
especially when equipment like laser interferometer is used to measure the length. Calculate after
the measured length is converted to the corresponding machine coordinates, or a wrong result may
occur.

When
“Screw error compensation” is set 0, and “Backlash compensation valid” is ste true, only
backlash compensation is valid.
When
“Screw error compensation” is set 1, and “Backlash compensation valid” is ste true, backlash
and signle direction error are compensated. It applies to when backlash is stable.
When
“Screw error compensation” is set 2, comprehensive compensation of positive error and
