Note

NOTE

1 When the power is turned on or the cleared state is set by a reset (bit 6 (CLR) of

parameter No. 3402 is set to 1), modal G codes are placed in the following
states:
(1) G codes marked with in G code lists are enabled.
(2) When the system is cleared due to power-on or reset, whichever specified,

either G20 or G21, remains effective.

(3) Bit 7 (G23) of parameter No. 3402 is used to specify whether G22 or G23 is

to be selected upon power-on. The selection of G22 or G23 is not, however,
changed when the CNC is cleared upon a reset. When the system is cleared
due to reset, whichever specified, either G22 or G23, remains effective.

2 G codes of group 00 except G10 and G11 are single-shot G codes.

NOTE

3 Alarm PS0010 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 If a G code of group 01 is specified in a canned cycle for drilling, the canned

cycle is canceled in the same way as when a G80 command is specified. G
codes of group 01 are not affected by G codes for specifying a canned cycle.

6 When G code system A is used for a canned cycle for drilling, only the initial

level is provided at the return point.

7 G codes are displayed for each group number.
