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.
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 Clear alarm with the Delete key or NC START.
Continuation:
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.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: - Modify part program
- Modify machine data
- Check whether SBL2 is activated. With SBL2, a block is generated from each part program line which
can lead to exceeding the maximum permissible number of empty blocks between two traversing
blocks.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10891 Channel %1 block %2 multiplicity of node is greater than its order
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In the B spline the distance between nodes PL (node = point on spline at which 2 polynomials meet)
has been programmed with zero too often in succession (i.e. the "multiplicity" of a node is too great).
In the quadratic B spline the node distance may not be specified more than twice with 0 in succession,
and in the cubic B spline not more than 3 times.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Program the node distance PL = 0 in succession no more than the degree of the B spline used.
Program Clear alarm with NC START or RESET key and continue the program.
