7.5 Supplementary conditions when selecting a transformation
Selection of transformations can be performed from
the part program or with MDA. Please note:
•
An intermediate motion block is not inserted
(chamfers/radii).
•
A spline block sequence must be completed,
otherwise a message is output.
•
Tool fine offset must be deactivated (FTOCOF),
otherwise a message is output.
•
Tool radius compensation must be deactivated
(G40), otherwise a message is output.
•
The control includes an activated tool length
compensation in the transformation.
•
The current frame that was active before the
transformation is deactivated by the control.
•
An active working area limitation is deselected for
the axes involved in the transformation by the
control (corresponds to WALIMOF).
•
Protection zone monitoring is deselected.
•
Continuous-path mode and approximate
positioning are interrupted.
•
DRF offsets of axes involved in the
transformation may not change between
execution of the preprocessing and main run
routines (Software Version 3 and lower).
•
All axes specified in the machine data must be
block-synchronized.
•
Exchanged axes are changed back again,
otherwise a message is output.
•
A message is output with dependent axes.
Tool change
A tool change can only be performed if tool radius
compensation is deselected.
A change in the tool length compensation and
selection/deselection of tool radius compensation
must not be programmed in the same block.
