Rounding values ( K and I) are limited within Notes :
the following values.
]Kl <lU/21
, Ill<lwl
The command exceeding the above value
causes format error.

Gll and G12 are modal G codes in the A group .
They remain effective until other G codes in
the group A are commanded.
Gll and G12 are for one axis only. If they
are commanded for both axes in the same
block, they constitute a format error.
EXAMPLE
G12 X.. . W.. . K.. . ;
Error “ 050”
In the G 10 or G
12 modes, no block without
I and K nor block in which I and K are O
can be commanded. If such a block is com-
manded, correct tool movement can not be
assured.
Tool radius compensation functional”is effec-
tive to the blocks containing G 11 or G 12.
In the finish form commands G70 through G 73
of the special canned cycle t, blocks contain–
ing Gll or G12 can be commanded.
GO1 code can be used instead of Gll to speci-
fy identical beveling.

GO1 code can be used instead of G12 to speci-

However, in this case, R must
be used instead of I and K.
