PTP for TRANSMIT

Function
PTP for TRANSMIT can be used to approach G0 and G1 blocks time-optimized. Rather than
traversing the axes of the Basic Coordinate System linearly (CP), the machine axes are
traversed linearly (PTP). The effect is that the machine axis motion near the pole causes the
block end point to be reached much faster.
The part program is still written in the Cartesian workpiece coordinate system and all
coordinate offsets, rotations and frame programming settings remain valid. The simulation on
HMI, is also displayed in the Cartesian Workpiece coordinate system.

For TRANSMIT, PTP means that in the Cartesian spirals will be retracted to
Archimedean spirals either about the pole or from the pole. The resulting tool
motions run significantly different as for CP and are represented in the
associated programming examples.

TU is not relevant for PTP with TRANSMIT
