Product function
1. Numerical Control Operation Master: Analyze the G code of the machining program, complete interpolation operation and trajectory calculation, output motion instructions to drive the servo units of each axis, and achieve machine tool cutting control.
2. Whole machine logic management: handle the PLC logic program of the machine tool, manage the machine tool IO signals, tool magazine, cooling, lubrication, door interlock and other auxiliary functions of the whole machine.
3. Human computer interaction docking: Connect the system operation panel and display screen, receive operator button commands, and provide feedback on machine status and alarm information.
4. Servo bus communication: Communicate with servo drivers through high-speed buses, read servo position and speed feedback, and form closed-loop motion control.
5. Equipment spare parts replacement: Used for repairing old Mazak machine tools, directly replacing the same model, restoring the CNC function of the entire machine, and reducing the cost of equipment renovation and shutdown.
Product features
- The integrated box type host of the whole machine is equipped with a CPU board, storage board, and bus interface, which can be directly installed in the electrical cabinet of the machine tool.
- Specially customized for Mazak machine tools, with built-in dedicated firmware that is compatible with Mazak equipment. Ordinary Mitsubishi system firmware cannot be directly used.
- Equipped with multiple sets of high-speed servo bus interfaces, IO slots, and storage card slots, supporting program and parameter backup and recovery.
Industrial grade hardware, capable of withstanding vibrations and temperature fluctuations in machine tool workshops, with complete hardware self diagnosis and the ability to output detailed fault alarm codes. - Supports memory card reading and writing, facilitating the import and export of processing programs, system parameters, and PLC programs.
- Rich interfaces, capable of connecting operation panels, display screens, servo drives, and external IO modules.
- When replacing, it is necessary to import the corresponding machine tool original parameters and PLC program in order to operate normally.
