Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10870
Channel %1 block %2 facing axis not defined
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: When constant cutting speed is activated via the G96 function, the spindle speed is con-
trolled through the position of the facing axis such that the cutting speed programmed
under S [mm/min] is applied at the tool tip. In the channel-specific MD 20100
DIAMETER_AX_DEF[n,m]=x (n ... channel index, m ... spindle index, x ... axis name), the
name of the facing axis [string] can be set for each of the 5 spindles that are used for the
speed calculation.
S [rpm] = (SG96 [m/min] x 1000) : (Dfacing axis [mm] x pi)
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
Remedy: Please inform the authorized personnel/service department. Enter the name of the facing
axis in the channel-specific machine data 20100 DIAMETER_AX_DEF for the spindles
used.
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 machine data 20200 CHFRND_MAXNUM_DUMMY_BLOCKS.
Reactions: - 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 20200 CHFRND_MAXNUM_DUMMY_BLOCKS (dummy blocks
with chamfers/radii) to the maximum number of dummy blocks.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
10881
Channel %1 block %2 overflow of local block buffer when inserting chamfers or
radii
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Between 2 blocks containing the contour elements and to be joined with a chamfer or a
radius (CHF, RND), so many dummy blocks have been programmed without contour
information that the internal buffer is too small.
Reactions: - Correction block is reorganized.
- Local alarm reaction.
- Interface signals are set.
- Alarm display.
