Overview of Alarms
NCK alarms
12722 Channel %1 block %2 multiple ISO_2/3 macro or cycle calls in the block
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A mixture of cycle and macro calls are programmed in a block, e.g. cycle calls with G81 - G89 together
with an M macro in the block or a G65/G66 macro call together with M macros in the block.
G05, G08, G22, G23, G27, G28, G29, G30, G50.1, G51.1, G72.1, G72.2 functions (ISO mode) also
execute subroutine calls. Only one macro or cycle call can appear in an NC block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Deactivate modal cycles or modal macro calls if one of the above mentioned G functions has been
programmed.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12724 Channel %1 block %2 no radius programmed for cylinder interpolation
activation/deactivation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: When programming G07.1 (cylinder interpolation TRACYL), no cylinder radius has been
programmed. Selection of the cylinder interpolation (TRACYL) with G07.1 C <cylinder radius>
deselect with G07.1 C0. For "C" the name of the rotary axis defined in the TRACYL machine data has
to be programmed.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: G07.1 block, program the cylinder radius under the name of the rotary axis for the cylinder
interpolation.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12726 Channel %1 block %2 illegal plane selection with parallel axes
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In a block with plane selection (G17 _ G19), a basic axis of the coordinate system must not be
programmed together with the parallel axis assigned to it.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: For plane selection with G17, G18, G19 either program the basic axis of the coordinate system or the
assigned parallel axis.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
12728 Channel %1 block %2 distance for double turret not set
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The tool clearance for the double turret head in the setting data
$SC_EXTERN_DOUBLE_TURRET_DIST is 0.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Enter tool clearance for the double turret head in the setting data
$SC_EXTERN_DOUBLE_TURRET_DIST.
Program Clear alarm with NC START or RESET key and continue the program.
