Working Area Limitations - Siemens SINUMERIK 840DE sl Function Manual

M1: Kinematics transformation
2.1 TRANSMIT face end transformation (option)
or
MD24951 $MC_TRANSMIT_POLE_SIDE_FIX_2= 1
processing is done before the rotational center point (linear axis in positive traversing range),
for
MD24911 $MC_TRANSMIT_POLE_SIDE_FIX_1= 2
or
MD24951 $MC_TRANSMIT_POLE_SIDE_FIX_2= 2
behind the rotational center point (linear axis in negative traversing range).
Transformation selection outside pole
The controller traverses the axes participating in the transformation without evaluating the
machine data MD24911 $MC_TRANSMIT_POLE_SIDE_FIX_<t>. <t> = 1 marks the first
TRANSMIT transformation and <t> = 2 marks the second TRANSMIT transformation in the
channel.

Working area limitations

Starting point
When TRANSMIT is active, the pole is replaced by a working area limitation if the tool center
point cannot be positioned at the turning center of the rotary axis involved in the transformation.
This is the case when the axis perpendicular to the rotary axis (allowing for tool offset) is not
positioned on the same radial plane as the rotary axis or if both axes are positioned mutually at
an oblique angle. The distance between the two axes defines a cylindrical space in the BCS in
which the tool cannot be positioned.
The illegal range cannot be protected by the software limit switch monitoring function since the
traversing range of the machine axes is not affected.
