10.4 Automatic path segmentation
Supplementary conditions
● If the C axis is not defined as a "Punch-nibble axis", then the C axis motion path is not
segmented in block N30 in the above example nor is a stroke initiated at the block end.
● If the functionality described above is to be implemented in a variant not specific to nibbling
applications, but with alignment of the special axis, then stroke initiation can be suppressed
by the following PLC interface signal:
DB 21, 22 DBX3.2 (stroke suppression)
(Application: e.g. alignment of electron beam during welding)
A similar response can be programmed with the following machine data setting:
MD26014 $MC_PUNCH_PATH_SPLITTING=1
In this case, the path is segmented irrespective of punching or nibbling functions.
