Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
10747 [Channel %1: ] Block %2 retraction direction not defined for WAB
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In a WAB retraction block with quarter circle or semi-circle (G248 or G348), the end point in the
machining plane was not programmed, and either G143 or G140 without tool radius compensation is
active.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program. The following changes are possible:
- Indicate end point in the machining plane in the WAB block.
- Activate tool radius compensation (effective for G140 only, not for G143).
- State retraction side explicitly with G141 or G142.
- Perform retraction with a straight line instead of a circle.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
10748 [Channel %1: ] Block %2 illegal retract plane with WAB
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: By means of DISRP a position of the retraction plane has been programmed which is not situated
between the safety distance (DISCL) and the starting point (during approach) and/or end point (during
retraction) of the WAB movement.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
10750 [Channel %1: ] Block %2 tool radius compensation activated without tool
number
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: A tool T... must be selected so that the control can make allowance for the associated compensation
values.
A correction data block (D1) containing the correction values (parameter P1 - P25) is automatically
assigned to each tool (T number). Up to 9 correction data blocks can be assigned to a tool by speci-
fying the required data block with the D number (D1 - D9).
The cutter radius compensation (CRC) is allowed for if function G41 or G42 is programmed. The cor-
rection values are contained in parameter P6 (geometry value) and P15 (wear value) of the active cor-
rection data block Dx.
Reaction: Correction block is reorganized.
Interpreter stop
Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Before calling the CRC with G41/G42, program a tool number under the address T...
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
10751 [Channel %1: ] Block %2 danger of collision due to tool radius
compensation
Parameters: %1 = Channel number
