Multiple axis system with enhanced safety functions
KEB America’s Combivert H6 is a multiple-axis system that features a TÜV-certified module that operates the standard rpm-dependent safety functions. Additional functions available in addition to safe torque off (STO) and SBC (safe brake control) include SS1 (safe stop 1); SS2 (safe stop 2); SOS (safe operating stop); SLS (safe limited speed); SLP (safe limited position); SLI (safe limited increment); SDI (safe direction); and SSM (safe speed monitoring).
All safety functions can be used in applications up to SIL3 according to IEC 61508 or up to PLe according to ISO 13849. As a necessary motor speed feedback signal resolvers or safety certified SinCos encoders are mandatory. The "Safety module Type 2" is controlled through safe digital inputs. The module’s ripple function allows building a simple ring structure so as to trigger the safety functions directly on another device. In addition, the safety module offers a 2-channel clock output for potential-free supply to the safety inputs.
The "Safety module Type 2" has the inherent task of safe parameterization. For this purpose, Combivis 6 and Combivis studio 6 have an offline cost-free safety module-editor by which password-protected access levels can be defined for various users. This structure allows users to save configurations and parameter lists and to use them in other projects, and also to load these into the module through the control.
