Overview of Alarms
Remedy: The calculation of the arc length function could not be performed to the required accuracy
during active polynomial interpolation. Either increase MD SPLINE_FEED_PRECISION
or reserve more memory for the representation of the arc length polynomials. MD
MM_ARCLENGTH_SEGMENTS defines how many polynomial segments can be used
per block in order to approximate the arc length function.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10951
Channel %1 block %2 curve table %3: following value period is zero
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Number of curve table
Definitions: --
Reactions: - Alarm display.
Remedy: Ensure that the table specification is correct.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
10955
Channel %1 block %2 curve table %3: missing master axis motion
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Number of curve table
Definitions: A slave axis motion has been programmed without a master axis motion. This can also
occur if, with active radius compensation, a block is created in which the slave axis moves
but not the master axis. The alarm is for information only and can be suppressed by set-
ting MD $MC_CTAB_ENABLE_NO_LEADMOTION = 2.
Reactions: - Alarm display.
Remedy: Alarm can be switched off via MD $MC_CTAB_ENABLE_NO_LEADMOTION = 2.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
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 (MD $MN_MM_NUM_CURVE_TABS_DRAM)
2: Number of linear curve table segments too small (MD
$MN_MM_NUM_CURVE_SEG_LIN_DRAM)
3: Number of polynomial curve table segments too small (MD
$MN_MM_NUM_CURVE_SEGMENTS_DRAM)
4: Number of curve table polynomials too small (MD
$MN_MM_NUM_CURVE_POLYNOMS_DRAM)
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
