SIEMENS SINUMERIK 840D SL

The SIMUMERIK 840D sl is a complete digital system that is best suited for mid or upper performance range.

Positive points:

• Maximum performance and flexibility, above all for complex multi-axis systems.
• Uniform openness from operation up to the NC core.
• Optimum integration into networks.
• Uniform structure in respect of operation, programming and visualization.
• Integral, certified safety functions for man and machine: SINUMERIK Safety Integrated
• Operating and programming software such as ShopMill or ShopTurn, as well as Motion Control Information System Products (MCIS-Products) can be used for the production sector.

The heart of the SINUMERIK 840D sl is the Numerical Control Unit (NCU). It combines NCK, HMI, PLC, closed-loop control and communication tasks.

The following components can be attached to the control unit:

• SINUMERIK operator panel front with TCU/PCU 50.3 and machine control

      Panel/pushbutton panel

• SIMATIC CE panel
• Handheld units
• SIMATIC S7-300 I/O
• Distributed PLC I/O via PROFIBUS-DP connection
• Programming device
• SINAMICS 120 converter system
• 1FK/1FT/1FN/1FW6/1PH/1FE1/2SP1/1LA motors

DRIVE CLIQ:

Abbreviation of "Drive Component Link with IQ".

Communication system for connecting the different components of a SINAMICS drive system (e.g. -> "Control Unit", -> "Line Module’s, -> "Motor Module’s, -> "Motor’s, and speed/position sensors. The DRIVE-CLiQ hardware is based on the Industrial Ethernet standard with twisted-pair lines. The DRIVE-CLiQ line provides the transmit and receive signals, as well as the +24 V power supply.

BASIC CONNECTION OF A 840D SL WITH DRIVE CLIQ:

CNC

Numerical control (NC) refers to the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to manually controlled via handwheels or levers, or mechanically automated via cams alone. The first NC machines were built in the 1940s and '50s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape. These early servomechanisms were rapidly augmented with analog and digital computers, creating the modern computed numerically controlled (CNC) machine tools that have revolutionized the manufacturing process.
