After the system is switched on, the valid modal G commands which are not executed their
functions or states are called initial mode G command. Take it as the initial mode G command to be
executed when it is not be input after the system is switched on.
3.1.2 Omitting words
To simplify the programming, their command values are reserved after executing words in Table
3-2. If the words are contained in the previous blocks, they cannot be input when the words are used
with the same values and definitions in the following blocks.
Table 3-2
Note 1: For the command addresses with functions (such as F, used for feedrate per minute, feedrate per
revolution and metric pitch and so on), they can be omitted not to input when executing the same
function to definite words after the words are executed. For example, after executing G98 F_ without
executing the thread command, the pitch must be input with F word when machining metric thread.
Note 2: They can be omitted not to input when the address characters X(U) , Z(W) are the coordinates of end
point of block and the system defaults the current absolute coordinates in X or Z direction to the
coordinate value of end point of block.
Note 3: The corresponding words must be input when the command addresses which are not in Table 3-2
are used.
