Motion commands
9.4 Rapid traverse movement (G0, RTLION, RTLIOF)
Further information
Rapid traverse velocity
The tool movement programmed with G0 is executed at the highest traversing speed (rapid
traverse). The rapid traverse speed is defined separately for each axis in machine data. If the
rapid traverse movement is executed simultaneously on several axes, the rapid traverse
speed is determined by the axis, which requires the most time for its section of the path.
Traverse path axes as positioning axes with G0
Path axes can travel in one of two different modes to execute movements in rapid traverse:
• Linear interpolation (previous behavior):
The path axes are interpolated together.
• Non-linear interpolation:
Each path axis interpolates as a single axis (positioning axis) independently of the other
axes of the rapid traverse motion.
With non-linear interpolation, the setting for the appropriate positioning axis (BRISKA, SOFTA,
DRIVEA) applies with reference to the axial jerk.
NOTICE
Since a different contour can be traversed in nonlinear interpolation mode, synchronized
actions that refer to coordinates of the original path are not operative in some cases!
