M1: Kinematic transformation
7.7 Cartesian manual travel (optional)
With ORIVIRT1, rotation is executed according to MD21120 $MC_ORIAX_TURN_TAB_1. The
orientation axes are assigned to the channel axes via machine data: MD24585
$MC_TRAFO5_ORIAX_ASSIGN_TAB_1.
The direction of rotation is determined according to the "right hand rule". The thumb points in
the direction of the rotary axis. The finger stipulates the positive direction of rotation.
Orientation in WCS
The rotations are made around the defined directions of the workpiece coordinate system. If
frame rotation is active, the movements correspond to the rotations in the basic coordinate
system.
Orientation in BCS
The rotations are made around the defined directions of the basic coordinate system.
