Special system reactions with TRANSMIT

The transformation can be selected and deselected via part program or MDA.

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.
