G-code control
A G-code program is analyzed and executed by a Motion controller.
G-code control is applied to various types of trajectory control such as drawing and cutting by a simple machine tool.
G-code control is available by additionally installing the G-code control add-on library (additional charge).
Features
- ● G-code programs can be edited on GOT and transmitted between GOT and a Motion CPU.
- ● Up to 16 axes can perform G-code control. (Simultaneous interpolation: Up to 4 axes)
- ● It is possible to switch between control by a servo program and by a G-code program.
- ● G-code control can be combined with other functions in Motion CPU such as Motion SFC program and synchronous control.
- ● A G-code program, which is in text format, can be edited with a generic editor.
- ● FTP transfer function allows transmission of data via a CC-Link IE compatible Ethernet interface module.
- (Note-1): USB memory can be connected only to GOT2000.
Applications
Processing with tool radius compensation
A plywood is processed precisely.
Processing with tool radius compensation
Burrs on the surface are removed.
Processing with normal line control
The outline is sealed at a constant speed.
[Applications]
- • Metal processing
- • Wood processing
- • Plastic processing
- • Various other material processing
Functions
- Automatic corner override
Reduces the load on the tool during inside corner cutting by automatic deceleration.
- Tool radius compensation
Compensates the path only for an amount of the tool radius.
- Normal line control
Controls the rotation of a rotating axis (C-axis) so that the tool is always in the normal direction.
Program development environment
A G-code program can be edited with a generic editor/GOT2000/CAD data conversion.
- ● Creating a G-code program with a generic editor
A G-code program is created in text format.
A generic editor can be used to create a new program or edit a program.
- ● Editing G-code Programs on GOT2000
G-code programs can be edited on GOT without a personal computer.
- ● Conversion from CAD Data into G-code
CAD data in DXF format is converted into a G-code program, and then the program is exported as G-code text data.
- (Note-1): Contact your local sales office for the CAD conversion tool.
In addition to conversion, it allows you to change the order of drawing.In order to edit the CAD data, CAD editing software is required.
Parameter
Set "G-code control axis parameter" to execute G-code control.
The parameter includes setting items such as:
- • Axis name (selected from X,Y,Z,A,B,C,U,V, or W)
- • Linear axis or Rotation axis selection
- • Fast forward speed
Combination of G-code Control and Synchronous Control
Trajectory with G-code control only
Trajectory with G-code control + conveyor axis
The G-code control axes can draw a true circle on a workpiece as the drawn trajectory is taking into account of the moving amount by the conveyor axis.
