Safely cutting costs
Integrated safety functions in the feeder unitNürnberg, )
As a standard, the safety function for drive systems is integrated decentralized in the individual motor current converters. When the electric motors are equipped with just a centrally switched STO control unit, the installation and wiring expenditures of the drive system are reduced, resulting in lower manufacturing costs.
The new safety concept fulfills the safety requirements SIL 2 according to IEC61508 or PLd, Category 3 according to DIN EN ISO 13849-1 and can be used for all applications where the feeder units and axis units have the same STO requirements.
