● Continuous path control and rounding are interrupted.
● DRF offsets in transformed axes must have been deleted by the operator.
Please note on deselection
● An intermediate motion block is not inserted (phases/radii).
● A series of spline blocks must be concluded.
● Tool radius compensation must be deselected.
● The frame which was active prior to TRANSMIT is deselected by the control system.
● Continuous path control and rounding are interrupted.
● DRF offsets in transformed axes must have been deleted by the operator.
● Tool length compensation in the virtual axis (Y axis in the figure) is not executed.
Restrictions when TRANSMIT is active
The restrictions listed below have to be observed for an activated TRANSMIT function.
Tool change
Tools may only be changed when the tool radius compensation function is deselected.
Frame
All instructions which refer exclusively to the base coordinate system are permissible
(FRAME, tool radius compensation). Unlike the procedure for inactive transformation,
however, a frame change with G91 (incremental dimension) is not specially treated. The
increment to be traversed is evaluated in the workpiece coordinate system of the new frame
– regardless of which frame was effective in the previous block.
Rotary axis
The rotary axis cannot be programmed because it is occupied by a geometry axis and
cannot thus be programmed directly as a channel axis.
Extensions
An offset in the rotary axis CM can be entered, for example, by compensating the inclined
position of a workpiece in a frame within the frame chain. The x and y values are then as
illustrated in the following diagram.
