NCU 572
NCU 573
Additional notes
1. CUTCONON has no effect if tool radius
compensation is not active (G40). An alarm is
output.
The G code remains active, however. This is
significant if tool radius compensation is to be
activated in a subsequent block with G41 or G42.
2. It is possible to change the G code in the 7th G
code group (tool radius compensation; G40 / G41
/ G42) when CUTCONON is active. A change to
G40 is effective immediately.
The offset with which the previous blocks were
traversed is applied.
3. If CUTCONON or CUTCONOF is programmed in
a block without a traversing movement in the
active compensation plane, the change does not
become effective until the next block with such a
traversing movement.
