Working area limitations

Starting position
When
point cannot be positioned in 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.
Figure 6-6
Traverse into working area limitation
Any motion that leads into the working area limitation is rejected with alarm 21619. Any
corresponding parts program block is not processed. The control system stops processing at
the end of the preceding block.
If the motion cannot be foreseen promptly enough (JOG modes, positioning axes), then the
control stops at the edge of the working area limitation.
Response close to working area limitation
If a tool center point traverses past the prohibited range, the control system automatically
reduces the feedrate and path acceleration rate such that the settings of the machine axes
(MD 32000 $MA_MAX_AX_VELO[AX*] and MD32300 $MA_ MAX_AX_ACCEL[AX*]) are not
exceeded. The closer the path is to the working area limitation, the greater the reduction in
the feedrate may be.
