Overview of Alarms
NCK alarms
16740 Channel %1 block %2 no geometry axis programmed
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: No geometry axis was programmed for tapping (G33) or for rigid tapping (G331, G332). The geometry
axis is, however, essential if an interpolation parameter has been specified.
Example:
N100 G33 Z400 K2 ; thread lead 2mm, thread end Z=400 mm
N200 SPOS=0 ; position spindle in axis mode
N201 G90 G331 Z-50 K-2 ; tapping to Z=-50, counterclockwise
N202 G332 Z5 ; retraction, direction reversal automatic
N203 S500 M03 ; spindle again in spindle mode
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Specify geometry axis and corresponding interpolation parameters.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
16746 Channel %1 block %2 spindle %3 selected gear stage %4 not installed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle number
%4 = Gear stage
Definitions: The first gear stage data block is active. The required gear stage is not installed in the 1st gear stage
data block. The number of gear stages installed is configured in machine data 35090
$MA_NUM_GEAR_STEPS.
Examples of the occurrence of the alarm with 3 three gear stages installed (MD 35090
$MA_NUM_GEAR_STEPS = 3):
* ... M44 or M45 has been programmed for the spindle concerned
*...M70 has been programmed and machine data 35014 $MA_GEAR_STEP_USED_IN_AXISMODE
is larger than 3.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Modify part program: Only those valid gear stages can be entered which have also been installed
according to machine data MA_NUM_GEAR_STEPS.
Limit M70 configuration (MD 35014 $MA_GEAR_STEP_USED_IN_AXISMODE) to MD 35090
MA_NUM_GEAR_STEPS.
Program Clear alarm with NC START or RESET key and continue the program.
