Statement:
The modal G code in table 1 is expressed with the *. Several G code may appears in the same block, but the
same G code can’t appear in the same block, otherwise the machine will alarm. Under the canned cycle mode, any
one of the G code which belongs to group 1 will cancel the canned cycle modal automatically and it will become
G80 modal.
4.1 Fast Positioning
In G00 code, the tool moves to the position that is specified by absolute command or relative command. The
quick ratio can be adjusted via the front panel, and there are F0, 25%, 50%, 100% fourth gears. The G00
instruction is rapid moving for positioning, which can’t be used for processing, only applies to air travel.
Format:
G00 X_Y_Z;
X_Y_Z: When under absolute programming, it is the end point values, and when under relative programming,
it’s the traveled distance of the tool.
Instruction:
The mode is G00 or G01 after power-on by parameter 0513.
The Maximum speed of each axis under G00 mode is set by the parameter 0904-0906.
4.2 The linear interpolation
Under G01 instruction, the tool moves in a straight line, and it’s modal.
Format:
G01 X_Y_Z_F;
X_Y_Z: When under absolute programming, it is the end point values, and when under relative programming,
it’s the traveled distance of the tool.
F: the feed rate of the tool, and the maximum feed rate of each axis is set by parameter by 0895-0897.
Instruction:
The tool moves to the specified location along a straight line under the specified feed of F. The F is modal
value, and the value is effective until the new value is specified. The G01 should be specified when first used, or
the machine will alarm
