1. If the CNC enters the clear state (see bit 6 (CLR) of parameter 3402)
when the power is turned on or the CNC is reset, the modal G codes
change as follows.
(1)G codes marked with in Table 3 are enabled.
(2)When the system is cleared due to power–on or reset, whichever
specified, either G20 or G21, remains effective.
(3)Setting bit 0 (G01) of parameter 3402 determines which code,
either G00 or G01, is effective.
(4)Setting bit 3 (G91) of parameter 3402 determines which code,
either G90 or G91, is effective.
2. G codes of group 00 except G10 and G11 are single–shot G codes.
3. P/S larm (No.010) is displayed when a G code not listed in the G code
list is specified or a G code without a corresponding option is
specified.
4. G codes of different groups can be specified in the same block.
If G codes of the same group are specified in the same block, the G
code specified last is valid.
5. For the A G–code system, the absolute and incremental commands are
distinguished by address words rather than G codes, G90 and G91.
6. G codes are displayed for each group number.
