Siemens 840Dsl CNC system adopts open design structure, which can be applied not only to CNC machine tools, but also to the field of motion control. Through the powerful industrial communication network of the system itself, it can be designed as an open loop or a closed loop to realize flexible production.

As a teaching and training system of numerical control electrical system in colleges and universities, the positioning cost is relatively high, and the system design of 840Dsl is highly open. Accordingly, the technical requirements for designers are also quite high.

840Dsl system is mainly divided into three parts:

1, HMI, man-machine interaction (mainly composed of man-machine unit PCU, machine tool control panel MCP, keyboard and mouse, optional touch screen, etc.). , processing and simulation, data management, PC communication, etc. )

2. Control and communication system (mainly including NC unit NCU, programmable controller PLC, peripheral communication module, input and output module, etc.). , realize interpolation operation, motion control, digital and analog control, etc. )

3. S 120 drive system. (It is mainly composed of S 120 drive system and 1FK series servo motors. It has the advantages of energy saving, high dynamic, stable and reliable axial movement and interpolation. Another advantage is that the S 120 drive system can be combined with other Siemens industrial automation products to form a motion control system.

If it is a training system in colleges and universities, it is not recommended to use 840Dsl system unless there is supporting technical training.
