SINUMERIK 840D sl BASIC –
Entry into the premium class with up to 6 axes.

SINUMERIK 840D sl Type 1B –
The new, higher-performance ratings class.

SINUMERIK 840D sl can be configured to suit your individual requirements. The consistently modular CNC-concept makes it possible to implement innovative machines which are tailored to individual needs. The hardware and software can be scaled independently of one another. The system can be configured flexibly for each machine and every manufacturing environment, even when the operating conditions are tough.

Distributed and flexible structure

One important feature of the SINUMERIK 840D sl is its distributed and simplified system structure – fully integrated into the design and communications structure of the SINAMICS S120 drive system. SINUMERIK 840D sl combines CNC, HMI, PLC, closed-loop control and communication tasks on one SINUMERIK NC-Unit (NCU). For increased operating performance (HMI), the SINUMERIK PCU 50.5 industrial PC can be used. The number of NC-axes can be increased to 93 with NCU-Link.

The rugged CNC system platform offers great scope for positioning components in the machine thanks to the distributed components for operation, drive and I/O. The components can be positioned at a distance of up to 100 m (328 ft) from each other. It is therefore possible, for example, to simultaneously connect up to four distributed OPs to one NCU/PCU. Thanks to the provision of an intelligent suppression mechanism, it is also possible to use more than four operator panels. Even the powerful multiprocessor NCU modules can be set up separately at a distance of up to 100 m (328 ft) from the SINAMICS S120 drive system.
