Overview of Alarms
14545
Channel %1 block %2 contour tool: edge D%3 completely encircles edge D%4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Edge number, label
%4 = Edge number, label
Definitions: On defining a contour tool, tangents are placed on the adjacent circular edges. It will not
be possible, if one edge is completely encircled by another one.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Change tool definition.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14546
Channel %1 block %2 contour tool: edge D%3 defines a concave corner
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Edge number, label
Definitions: The contour of a contour tool must be convex throughout, i.e. there must not be any con-
cave corners.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Change tool definition.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14547
Channel %1 block %2 contour tool: checksum erroneous or not available
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: When machine date $MC_SHAPED_TOOL_CHECKSUM was set, no edge was found for
which the tool length components and the tool radius equal the negative sum of the previ-
ous edges.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm at block end.
Remedy: Check tool definition. An edge must exist, the tool length components and tool radius of
which equal the negative sum of the previous edges. This will not take the tool length
components of the first edge into consideration. On comparing the components, the rele-
vant sums of basic value and wear value are compared with each other, not the part com-
ponents themselves.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14548
Channel %1 block %2 contour tool: negative radius in edge D%3 is not allowed
