LNotes:

–The * marked G codes in a group represent the state assumed by the control system after power- on.

–If several codes are marked with * in a group, a parameter can be set to select the effective one after power-on. They are : G00, G01; G17, G18; G43, G44, G49; G90, G91; G94, G95.

–At the time of power-on, the particular one of G20 and G21 will be effective, that has been set at the time of power-off.

–Default interpretation of command G05.1 after power-on can be specified with the MULBUF parameter.

–G codes in group 00 are not modal ones; the rest are so.

–More than one G code can be written in a block with the restriction that only one of the same function group may used.

–Reference to an illegal G code or specification of several G codes belonging to the same group within a particular block will produce error message 3005 ILLEGAL G CODE.
