Overview of Alarms
NCK alarms
26260 Channel %1 block %2: Collision of the two protection areas %3 and %4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Name of 1st protection area
%4 = Name of 2nd protection area
Definitions: The two protection areas named collide in the indicated block, i.e. the distance between the two
protection areas is smaller than the value defined by machine date $MN_COLLISION_TOLERANCE.
Reaction: Correction block is reorganized.
Alarm display.
NC Stop on alarm.
Remedy: Change NC program or definition of the protection areas involved.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
26262 Channel %1: Not enough memory space during collision test of the two
protection areas %2 and %3. Nominal / Actual: %4
Parameters: %1 = Channel number
%2 = Name of 1st protection area
%3 = Name of 2nd protection area
%4 = Nominal / Actual
Definitions: The collision check of two protection zones requires temporary internal memory space, the size of
which depends on the number of elements contained in the protection areas and the number of
machine axes.
If the 1st protection zone has m elements and the 2nd protection zone n elements and there are k
machine axes, then a maximum of 4 * n *m * k memory spaces, each of 4 bytes, are required.
Example:
1st protection zone has 20 elements
2nd protection zone has 25 elements
There are 5 machine axes
A temporary memory space of 4 * 4 * 20 * 25 * 5 = 40000 bytes is required.
The size of the available memory space can be changed in machine data $MN_MM_3D_COLLISION.
Reaction: Correction block is reorganized.
Alarm display.
NC Stop on alarm.
Remedy: Change NC program or definition of the protection areas involved.
Adjust machine date $MN_MM_3D_COLLISION.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
26264 Channel %1 block %2: The protection area with the name %3 was not
found.
Parameters: %1 = Channel number
%2 = Block number
%3 = Name of protection area
Definitions: One protection area with the name indicated was not found (e.g. during function call PROTA).
Reaction: Correction block is reorganized.
Alarm display.
NC Stop on alarm.
Remedy: Indicate the name of an existing protection area or define the protection area with the name indicated.
Program Clear alarm with NC START or RESET key and continue the program.
