B&R frequency inverters Total integration Safety level PL e Integrated safety is an important highlight of this inverter family. The following safety functions are always integrated in these devices: STO (Safe Torque Off) for the ACOPOSinverter P74 and P84, SLS (Safely Limited Speed) and SS1 (Safe Stop 1) for the ACOPOSinverter P74. Depending on the configuration and wiring of the frequency inverter, these safety functions satisfy IEC/EN 61508-1 SIL 2/3 and ISO 13849-1 PL d/e requirements. Frequency inverters System overview Quick and easy configuration These frequency inverters are configured and diagnosed using Automation Studio. The external 24 VDC supply for the frequency inverter control unit and communication allows this even if the supply voltage has been switched off. All parameters are saved to the PLC and transferred to the frequency inverter automatically. Commissioning can therefore be done quickly and easily without requiring specific knowledge of frequency inverters. Embedded POWERLINK interface The ACOPOSinverter P74 fits seamlessly into the B&R Motion product portfolio thanks to its integrated POWERLINK interface. Excellent flexibility is achieved by combining servo drives and frequency inverters on a POWERLINK network and by the uniform control offered by B&R‘s Generic Motion Control system. < Power range from 180 W to 90 kW < Complete integration into overall system < Automatic parameter download < Integrated safety functions B&R Corporate Headquarters Bernecker + Rainer Industrie-Elektronik Ges.m.b.H.
