Overview of Alarms
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 travers-
ing 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 break-
ing) 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.
Reactions: - 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 maxi-
mum 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 machine data
$MN_ENABLE_ALARM_MASK. Otherwise, the chamfer or radius is adapted without an
alarm being output.
Reactions: - 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.
tinuation:
10890
Channel %1 block %2 overflow of local block buffer when calculating splines
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The maximum permissible number of empty blocks is limited by a machine data.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
Remedy: • Modify part program
