Overview of Alarms
NCK alarms
17502 Channel %1 block %2 indexing axis %3 with Hirth tooth system stop is
delayed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
Definitions: For the indexing axis, the 'Hirth tooth system' function is activated and the override has been set to 0
or another stop condition (e.g. VDI interface signal) is active. Since it is possible to stop only on
indexing axes, the next possible indexing position is approached. The alarm is displayed until this
position is reached or the stop condition is deactivated.
Reaction: Alarm display.
Remedy: Wait until the next possible indexing position is reached or set override > 0 or deactivate another stop
condition.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
17503 Channel %1 block %2 indexing axis %3 with Hirth tooth system and axis
not referenced
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name
Definitions: The 'Hirth tooth system' function is activated for the indexing axis and the axis is to be traversed
although it is not referenced.
Reaction: Alarm display.
Remedy: Reference axis.
Program Clear alarm with the Delete key or NC START.
Continuation:
17510 Channel %1 block %2 invalid index for indexing axis %3
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: The programmed index for the indexing axis is beyond the position table range.
Example:
Perform an absolute approach of the 56th position in the list allocated via the axis-specific machine
date 30500 INDEX_AX_ASSIGN_POS_TAB with the 1st positioning axis, the number of positions is
e.g. only 40 (MD 10900 INDEX_AX_LENGTH_POS_TAB_1 = 40).
N100 G.. U=CAC (56)
Or, with equidistant distances, the programmed index is smaller or equal 0.
Or, an attempt is made with a MOV movement to travel to a position outside the permitted area.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: Program the indexing axis position in the NC part program in accordance with the length of the current
position table, or add the required value to the position table and adjust the length of the list.
Program Clear alarm with the RESET key. Restart part program
