M1: Kinematic transformation

6.9 Constraints

Persistent transformation
Machine data which are relevant for persistent transformations:
● MD20144 $MC_TRAFO_MODE_MASK
● MD20140 $MC_TRAFO_RESET_VALUE
● MD20110 $MC_RESET_MODE_MASK and
Not transformation-specific
Machine data that are not transformation-specific. they are not uniquely assigned to a
particular transformation data set or they are relevant even when a transformation is not
active:
● MD21110 $MC_X_AXIS_IN_OLD_X_Z_PLANE
● MD21090 $MC_ MAX_LEAD_ANGLE
● MD21092 $MC_ MAX_TILT_ANGLE
● MD21100 $MC_ORIENTATION_IS_EULER

6.9.1

Chained transformations

Two transformations can be chained.
However, not just any transformation can be chained to another one.
In this case, the following restrictions apply:
● The first transformation of the chain has to be one of the following transformations:
● The second transformation must be aninclined axis transformation.
● Only two transformations may be chained.
It is allowed (for test purposes, for instance), to enter only a single transformation into the
chaining list.
