● SUPD may not be used in conjunction with the following functions:
– 3D tool radius compensation for 3D face milling (CUT3DFxx)
– Curve tables (CTAB)
● The use of SUPD with active tool radius compensation (G41/G42) is possible, but not
recommended.
To activate the function nevertheless, the following setting data must be set to "0":
SD42480 $SC_STOP_CUTCOM_STOPRE = 0
This prevents that the program is interrupted with active G41/G42.
Example
When traversing, the tool length shall be suppressed in the subprogram SUB_SUP.
