2.1 Application
Overview
SINUMERIK 840D sl oers modularity, openness, exibility and uniform structures for operation,
programming, and visualization. It provides a system platform with trend-setting functions for
almost all technologies.
Integrated into the SINAMICS S120 drive system and complemented by the SIMATIC S7-300
automation system, the SINUMERIK 840D sl forms a complete digital system that is ideally suited
for the mid to upper performance range.
SINUMERIK 840D sl is characterized by:
• A high degree of exibility
• Excellent dynamic response and precision
• Optimum integration into networks
Benets
• Outstanding performance and exibility for multi-axis systems of average to high complexity
thanks to scalable hardware and software.
• Universal openness of the user interface, the PLC and the NC kernel to allow integration of
your specialist know-how.
• Integrated safety functions for man and machine: SINUMERIK Safety Integrated.
• Comprehensive range of products for integrating machine tools into communication,
engineering and production processes: SINUMERIK Integrate
Fields of application
The SINUMERIK 840D sl can be used worldwide for turning, drilling, milling, grinding, laser
machining, nibbling, punching, in tool and mold making, for high-speed cutting applications,
for wood and glass processing, for handling operations, in transfer lines and rotary indexing
machines, for mass production and JobShop production.
The SINUMERIK 840DE sl is available as an export version for use in countries requiring an export
authorization.
2.2 System conguration
SINUMERIK 840D sl combines CNC, HMI, PLC, closed-loop control, and communication tasks
within a single NCU (Numerical Control Unit).
