Limitation
- Rotation axis specification
A rotation axis must not be specified in specified-direction tool length
compensation mode. Otherwise, an alarm (PS0809) is issued.
- Commands related to reference position return
The specified-direction tool length compensation mode must be
cancelled before any of the following can be specified:
- Reference position return check (G27)
- Return to reference position (G28)
- Return to 2nd reference position (G30)
- Return from reference position (G29)
- Coordinate system rotation, scaling
In specified-direction tool length compensation mode, coordinate
system rotation and scaling are applied to the tool tip position.
- Three-dimensional coordinate conversion
When specified-direction tool length compensation is used during
three-dimensional coordinate conversion, three-dimensional
coordinate conversion is applied to the tool axis directions (I, J, K) as
well.
