Overview of Alarms
NCK alarms
10880 Channel %1 block %2 too many empty blocks between two traversing
blocks when inserting chamfers or radii
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Between 2 blocks containing contour elements and which are to be joined with a chamfer or a radius
(CHF, RND), more blocks without contour information have been programmed than provided for in the
machine data 20200 CHFRND_MAXNUM_DUMMY_BLOCKS.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Modify the part program in order that the
permissible number of dummy blocks is not exceeded or adapt the channel-specific machine data
20200 CHFRND_MAXNUM_DUMMY_BLOCKS (dummy blocks with chamfers/radii) to the maximum
number of dummy blocks.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10881 Channel %1 block %2 overflow of local block buffer when inserting
chamfers or radii
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Between 2 blocks containing the contour elements and to be joined with a chamfer or a radius (CHF,
RND), so many dummy blocks have been programmed without contour information that the internal
buffer is too small.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Modify part program such that the number of dummy blocks is reduced.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10882 Channel %1 block %2 activation of chamfers or radii (non-modal) without
traversing movement in the block
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: No chamfer or radius has been inserted between 2 linear or circle contours (edge breaking) because:
- There is no straight line or circle contour in the plane
- There is a movement outside of the plane
- A plane change has taken place
- The permissible number of dummy blocks without traversing information has been exceeded.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Correct the part program according to the
above error description or change the number of dummy blocks in the channel-specific MD
CHFRND_MAXNUM_DUMMY_BLOCKS to comply with the maximum number allowed for in the
program.
Program Clear alarm with NC START or RESET key and continue the program.
