Supplementary Conditions And Control System Response For Orientation - Siemens SINUMERIK 840Di Function Manual

This number of toolholder data sets, divided by the number of active channels, can be
defined for a channel.
Exception:
If non-standard settings are selected via machine data:
MD28085 $MC_MM_LINK_TOA_UNIT.
Canceling all toolholder data blocks
All values of all toolholder data sets can be deleted from within the part program using one
command.
$TC_CARR1[0] = 0
Values not set by the user are preset to 0.
Activation
A toolholder becomes active when both a toolholder and a tool have been activated. The
selection of the toolholder alone has no effect. The effect of selecting a toolholder depends
on the G code TCOABS/TCOFR (modal G-code group for toolholders).
Changing the G code in the TCOABS/TCOFR group causes recalculation of the tool length
components when the toolholder is active. With TCOABS, the values stored in the toolholder
data for both angles of rotation α1and α2 are used to determine the tool orientation.
With TCOFR, the two angles are determined from the current frame. The values stored in the
toolholder data are not changed, however. These are also used to resolve the ambiguity that
can result when the angle of rotation is calculated from one frame. Here, the angle that
deviates least from the programmed angle is selected from the various possible angles.
