Decentralized installation with a decentralized
MOVIFIT
®
MC or FC drive controller and integrated functional safety
Features and advantages
–
Comprehensive safety functionality for disconnection, speed and direction of rotation monitoring
(STO, SS1, SLS, SDI)
–
Reduced wiring work through the integration of functional safety technology
–
Short total response times of the application due to direct monitoring and disconnection
–
Fast startup with simple parameterization of complete safety functions
–
Easy and guided validation of safety functionality
–
Stand-alone safety solutions in independent operation without external safety controller possible
–
Long product life of the safety components due to long service life (20 years)
–
Easy integration of safe drive technology in existing plants with PROFIsafe communication
–
Universal application in a PROFIsafe network via PROFIBUS and PROFINET IO via S12 safety
