Integrated safety functions in the Sinumerik drive from Siemens meet the requirements of safety Category 3, compliance with EN 954-1, and are an integral part of the basic system. Additional sensors are not necessary, which reduces machine installation effort and results in a "slimline" control cabinet. The scope of functions supported includes system monitoring at speed and standstill, as well as functions for safe travel range limiting and range detection.
A multi-processor architecture forms a dual-channel, system structure, and safety functions are redundantly integrated in NC, drive and internal PLC. Process variables and safety-relevant system data are cross monitored. Safety functions are available in all operating modes and communicate with the process using input/output signals.
