Definitions: The 'Hirth tooth system' function is activated for the indexing axis. This axis can therefore approach
only indexing positions, another travel movement of the axis is not possible.
Reaction: Interpreter stop
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department.
Correct part program.
Correct FC16 or FC18 call.
Deselect machine data MD30505 $MA_HIRTH_IS_ACTIVE.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
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 index-
ing 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 Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
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 Con- Clear alarm with the Delete key or NC START.
tinuation:
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 MD30500
$MA_INDEX_AX_ASSIGN_POS_TAB with the 1st positioning axis, the number of positions is e.g.
only 40 (MD10900 $MN_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.
