Overlaid movements
DRF offset or external zero offset are only possible to a limited extent in Cartesian PTP
travel. When changing from PTP to CP movement, there must be no overrides in the BCS.
Smoothing between CP and PTP motion
A programmable transition rounding between the blocks is possible with G641.
The size of the rounding area is the path in mm or inch, from which or to which the block
transition is to be rounded. The size must be specified as follows:
• for G0 blocks with ADISPOS
• for all the other motion commands with ADIS.
The path calculation corresponds to considering of the F addresses for non-G0 blocks. The
feed is kept to the axes specified in FGROUP(..).
Feed calculation
For CP blocks, the Cartesian axes of the basic coordinate system are used for the
calculation.
For PTP blocks, the corresponding axes of the machine coordinate system are used for the
calculation.
7.9.1 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 parts 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.
