2. Formulate the interface format and define the input/output signals? It is necessary to design and write the following interface technical documents: schematic diagram of input and output signal circuit, address table and PLC data table.
3. Make a ladder diagram? On the basis of analyzing the working principle or action sequence of machine tool, the logical sequence relationship between signal and machine tool movement is described by process entity and time sequence entity, and the ladder diagram is designed and made accordingly.
4. Sequential input, debugging and confirmation? Convert ladder diagram into instruction table format, and then write sequential program with programmer chain disk. Next, debug and modify with simulation equipment or simulation platform.
Extended data:
First, the engraving machine operation process
1. typesetting according to customer requirements and design requirements. After calculating the paths correctly, save the paths of different tools to different files.
2. After checking that the path is correct, open the path file (preview) in the control system of the engraving machine.
3. Fix the materials and define the starting point of the work. Turn on the spindle motor and adjust the value correctly.
4. Turn on the power and operate the machine.
Second, the matters needing attention before the installation of engraving machine
1. Do not install this equipment during lightning or thunder, do not install a power socket in a damp place, and do not touch the uninsulated power cord.
2. Operators must undergo strict training, pay attention to personal safety and machine safety, and operate the computer engraving machine in strict accordance with the operating procedures.
3. The required power supply voltage is 2 10V-230V(380V). If the power supply voltage is unstable or there are high-power electrical equipment around, please be sure to choose a regulated power supply under the guidance of professional and technical personnel.
4, engraving machine, control cabinet must be grounded, no charged data line.
5, the operator shall not wear gloves to work, it is best to wear goggles.
6. The mechanical body is made of aviation aluminum castings in the gantry part of the steel structure, which is relatively soft. When installing the screws (especially when installing the engraving motor), do not use too much force to prevent slipping.
7. The cutter must be clamped to keep the cutter sharp. A blunt cutter will reduce the engraving quality and overload the motor.
8. Don't put your fingers into the working range of the tool, and don't take off the carving head for other purposes. Do not process materials containing asbestos.
9. Don't go beyond the processing range. Cut off the power supply when you don't work for a long time. When the machine moves, it must be carried out under the guidance of professionals.
10. If the machine is abnormal, please refer to the troubleshooting chapter in the operation manual or contact the dealer for solution; So as not to cause man-made damage.
