4.4 Predefined procedures
Explanation
Transformation inclined axis
Several transformations can be set per channel. The
transformation number specifies which transforma‐
tion is to be activated. If the 2nd parameter is omitted,
the transformation grouping set via MD is activated.
If the angle is not programmed
(TRAANG ( ,2) or TRAANG)
the last angle applies modally.
4-axis, 5-axis transformation
Several transformations can be set per channel. The
transformation number specifies which transforma‐
tion is to be activated.
Cascaded transformation
The meaning of the parameters depends on the type
of cascading.
Deactivate transformation
Activate a transformation defined with kinematic
chains
Explanation
Switch to position-controlled spindle operation.
Switch to speed-controlled spindle operation.
Declaration of spindle as master spindle for the cur‐
rent channel
With SETMS( ), the machine data default applies au‐
tomatically without any need for parameterization.
