(Note 1) G codes marked 7 are initial G codes when turning power on. For G20 and G21, the G code
before turning power off remains. GO0 or GO1 can be selected by parameter GO1 (No. 3402440).
G17, G18, or G19 can be selected by parameters G18 (bit 1 of parameter No. 3402) and Gig (bit 2 of
parameter No. 3402). G90 or G9t can be selected by parameter G91 (bit 3 of parameter No. 3402).
(Note 2)
G codes of group 00 are not modal. They are only effective in the block in which they are specified.
(Note 3) If a G code not listed on the table of G codes is input, or optional G code not specified in the system
is commanded, an alarm (No. 010) is displayed.
(Note 4) A number of G codes can be specified in the same block. When more than one G code of the
same group is specified, the G code specified later is effective.
(Note 5) If any G code of group 01 is specified in a canned cycle mode, the canned cycle is automatically
cancelled and the G80 condition is entered. However a G code of group 01 is not affected by any of the
canned cycle G codes.
