(Note 1)
Codes marked with * are codes that must be or are selected in the initial state.
The codes marked with
Δ
are codes that should be or are selected in the initial state by
the parameters.
(Note 2)
If two or more G codes from the same code are commanded, the latter G code will be
valid.
(Note 3)
This G code list is a list of conventional G codes. Depending on the machine, movements
that differ from the conventional G commands may be included when called by the G
code macro. Refer to the Instruction Manual issued by the tool builder.
(Note 4)
Whether the modal is initialized or not depends on each reset input.
(1) "Reset 1"
The modal is initialized when the reset initial parameter "#1151 rstinit" turns ON.
(2) "Reset 2" and "Reset & rewind"
The modal is initialized when the signal is input.
(3) Resetting when emergency stop is canceled
Follows "Reset 1".
(4) When modal is automatically reset at the start of individual functions such as
reference position return.
Follows "Reset & rewind".
CAUTION
The commands with "no value after G" will be handled as "G00".
3.8 Precautions Before Starting Machining
Precautions before starting machining
CAUTION
When creating the machining program, select the appropriate machining conditions so that the
machine, NC performance, capacity and limits are not exceeded. The examples do not allow
for the machining conditions.
Before starting actual machining, always carry out dry operation to confirm the machining
program, tool compensation amount and workpiece offset amount, etc.
