Overview of Alarms
NCK alarms
10956 [Channel %1: ] Block %2 curve table %3: NC memory limit DRAM reached
type %4.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Number of curve table
%4 = Object type
Definitions: Insufficient memory in the DRAM while defining the curve table.
The object type parameter specifies for which curve table object
the memory will not suffice:
1: Number of curve tables too small (MD18406 $MN_MM_NUM_CURVE_TABS_DRAM)
2: Number of linear curve table segments too small (MD18409
$MN_MM_NUM_CURVE_SEG_LIN_DRAM)
3: Number of polynomial curve table segments too small (MD18408
$MN_MM_NUM_CURVE_SEGMENTS_DRAM)
4: Number of curve table polynomials too small (MD18410
$MN_MM_NUM_CURVE_POLYNOMS_DRAM)
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Delete the curve tables that are no longer required in DRAM or reconfigure the memory space for the
curve tables. The curve table must then be redefined. Machine data for memory configuration of the
curve tables in DRAM:
MD18406 $MN_MM_NUM_CURVE_TABS_DRAM, MD18408
$MN_MM_NUM_CURVE_SEGMENTS_DRAM, MD18409
$MN_MM_NUM_CURVE_SEG_LIN_DRAM, MD18410
$MN_MM_NUM_CURVE_POLYNOMS_DRAM.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
10958 [Channel %1: ] Lin. curve table %2, memory type %3 includes %4
polynomial segments.
Parameters: %1 = Channel number
%2 = Number of curve table
%3 = Memory type
%4 = Number of polynomial segments
Definitions: On generating the curve table with the specified ID in the specified memory type
(1 = SRAM, 2 = DRAM), polynomial segments were used instead of possible linear segments.
By increasing the number of linear curve table segments by the indicated number, the
curve table can be saved in a better way.
The following machine data are involved depending on the memory type:
1 (SRAM): MD18403 $MN_MM_NUM_CURVE_SEG_LIN
2 (DRAM): MD18409 $MN_MM_NUM_CURVE_SEG_LIN_DRAM
Reaction: Alarm display.
Remedy: The indicated curve table can be created and optimized for the memory by increasing
MD18403 $MN_MM_NUM_CURVE_SEG_LIN or MD18409
$MN_MM_NUM_CURVE_SEG_LIN_DRAM
and repeating table generation.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
10960 [Channel %1: ] Block %2 COMPCURV/COMPCAD and radius
compensation can-notbe used simultaneously
Parameters: %1 = Channel number
%2 = Block number, label
