Integrated safety functions in the feeder unit
The drive and automation specialist Baumüller is now offering a new safety solution for the stackable converter generation b maXX 5000. Here the electric motors are no longer shut off in a decentralized process in the individual motor converters but centrally, with one of the STO modules (Safe Torque Off) integrated into the feeder unit.
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 up to SIL 3 and PLe and can be used for all applications where the feeder units and axis units have the same STO requirements.
