Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10881 [Channel %1: ] Block %2 overflow of local block buffer in the case of
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 Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 the plane
A plane change has taken place
The permissible number of empty blocks without traversing information (dummy blocks) 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 MD20200
$MC_CHFRND_MAXNUM_DUMMY_BLOCKS to comply with the maximum number allowed for in
the program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10883 [Channel %1: ] Block %2 chamfer or fillet has to be reduced
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: This alarm is output, if at least one of the relevant blocks when inserting chamfers or radii is so short,
that the contour element to be inserted must be reduced against its originally programmed value. The
alarm occurs only if bit 4 is set in the MD11411 $MN_ENABLE_ALARM_MASK. Otherwise, the cham-
fer or radius is adapted without an alarm being output.
Reaction: Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify NC program of continue program without modifications after CANCEL and Start or with Start
alone.
Program Con- Clear alarm with the Delete key or NC START.
