CHAPTER 3 G COMMANDS
3.1 Commands
G command consists of command address G and its following 1～2 bits command value,
used for defining the motion mode of tool relative to the workpiece, defining the
coordinates and so on. Refer to G commands as Fig. 3-1.
G words are divided into 9 groups (00, 01, 02, 03, 06，07，12，14，16，21). Except that
commands in the group 01 and 00 are not in the same block, G words in the different
groups can be input to the same block and the last one is valid when two or more G words
in the same group are input. The words in the different groups without the same
parameter (word) can be in the same block and their functions are valid without sequence
at the same time. The system alarms when G words do not belong to Table 3-1 or they
are optional functions without being supplied.
