Product Overview Model Name: NCU 573.3 (or similar models, subject to the official documentation for details) Belonging series: SINUMERIK 840D/840Di sl Positioning: The core control unit of the numerical control system, responsible for multi-axis motion control, PLC logic processing and data communication. 2. Key functions and features Multi-axis control: Supports complex multi-axis linkage (such as 5-axis processing), and the maximum number of controllable axes is usually 31 servo axes (depending on the configuration). High-performance processor: Based on Siemens' dedicated processor, it processes numerical control programs (such as G-code) and PLC logic in real time (integrating the functions of S7-300 series PLC). Communication interface: PROFIBUS DP: It is used to connect drive modules (such as SIMODRIVE 611), I/O modules and peripheral devices. Ethernet interface: Supports TCP/IP protocol, used for PC connection, remote diagnosis or data backup. Storage capacity: Equipped with large-capacity memory, it supports the storage of complex processing programs (such as HMI human-machine interface programs, user data, etc.). Compatibility: Seamless integration with Siemens' SINAMICS drive system, supporting digital servo drive control. 3. Application fields High-end CNC machine tools: such as five-axis milling machines, turning and milling compound centers, grinding machines, etc. Automated production line: Suitable for high-precision demand scenarios such as aerospace, automotive manufacturing, and mold processing. 4. Technical Parameters (Typical Values) Power supply voltage: 24V DC (typical industrial power input). Operating temperature: 0°C to 55°C (subject to industrial environmental standards). Protection grade: Usually IP20, it needs to be installed in an electrical control cabinet. Firmware support: Programming and debugging need to be carried out through Siemens dedicated tools (such as PCIN, STEP7). 5. Supporting components Drive module: such as SIMODRIVE 611U or SINAMICS S120. Operation Panel: Used in conjunction with the OP (Operator Panel) or PCU (Panel Control Unit) of the same series. Software tools: Siemens STEP7 is required for PLC programming, and SINUMERIK Operate is used for the operation of the numerical control interface.
