Channel %1 block %2 danger of collision due to tool radius compensation
%1 = Channel number
%2 = Block number, label
The 'bottle neck detection' (calculation of the intersection point of the follow-
ing, corrected traversing blocks) was not able to calculate an intersection point
for the overviewed number of traversing blocks, resulting in the risk that one of
the equidistant paths will violate the workpiece contour.
Alarm display.
Interface signals are set.
NC Start inhibited.
Check the part program and modify the program (if possible) such that inner
corners with paths shorter than the compensation value are avoided. (Outer
corners are not critical, since the equidistants are elongated or intermediate
blocks are inserted so that an intersection point is always provided).
Press the RESET key to clear the alarm. Restart part program.
Channel %1 block %2 overflow of local block buffer with tool radius
compensation
%1 = Channel number
%2 = Block number, label
The tool radius compensation must buffer an alternating number of intermedi-
ate blocks in order to be able to calculate the equidistant tool path for each NC
block. The size of the buffer memory cannot easily be determined. It depends
on the number of blocks without traversing information in the compensation
level and the number of contour elements to be inserted.
The size of the buffer memory is fixed by the system and cannot be altered via
MD.
Alarm display.
Interface signals are set.
NC Start inhibited.
Reduction of the buffer memory which has been occupied by modifying the NC
program. This can be achieved if you avoid the following:
•
blocks without traversing information in the compensation level
•
blocks that contain contour elements with variable curves (e.g. ellipses)
and curve radii which are smaller than the compensation radius. (Such
blocks are split into several partial blocks).
Press the RESET key to clear the alarm. Restart part program.
