Overview of Alarms
NCK alarms
10866 [Channel %1: ] Block %2 FZ is active, but the number of teeth of the
active D number %4 of tool %3 is zero.
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Identifier
%4 = D number
Definitions: Tooth feedrate is active for the displayed traversing block, but a D number of 0 is selected with
$TC_DPNT (number of teeth).
Traversing can be performed after acknowledgement of the error. For calculation of the effective fee-
drate one tooth per revolution is assumed.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Check the NC program for correct tool selection and correct it, if required;
then continue the NC program with NC start.
Or:
Continue the NC program with NC start. The feedrate will be calculated assuming
1 tooth.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10870 [Channel %1: ] Block %2 facing axis for constant velocity not defined
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Constant cutting speed was selected although no transverse axis was applied as reference axis for
constant cutting speed or assigned through SCC[AX].
Constant cutting speed can be activated as follows:
- Basic position G96, G961 or G962 of G group 29 during booting
- Programming of G96, G961 or G962
A reference axis for G96, G961 or G962 can be applied as a transverse axis in MD20100
$MC_DIAMETER_AX_DEF or defined through the instruction SCC[AX].
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Check MD20100
$MC_DIAMETER_AX_DEF. Before programming G96, G961 or G962 a transverse axis must be
defined as a reference axis for constant cutting speed via MD20100 $MC_DIAMETER_AX_DEF or
SCC[AX].
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10880 [Channel %1: ] Block %2 too many empty blocks between two traversing
blocks when inserting chamfers or radii
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Between 2 blocks containing contour elements and which are to be joined with a chamfer or a radius
(CHF, RND), more blocks without contour information have been programmed than provided for in the
MD20200 $MC_CHFRND_MAXNUM_DUMMY_BLOCKS.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department. Modify the part program in order that the
permissible number of dummy blocks is not exceeded or adapt the channel-specific machine data
MD20200 $MC_CHFRND_MAXNUM_DUMMY_BLOCKS (dummy blocks with chamfers/radii) to the
maximum number of dummy blocks.
