B&R’s relay-free SafeMC safety circuit, which is installed in all ACOPOSmulti drive units, automatically monitors how the motor responds to instructions from the servo drive. This is done using fully digital encoders that are certified according to EN ISO 13849. The electronics are integrated directly on the drive to avoid increasing response times. The safe servo drives from B&R promote optimal use of safety equipment, according to the company, because double wiring is no longer necessary and external monitoring modules are provided. In addition, ACOPOSmulti with SafeMC can be seamlessly integrated in the existing system with the SafeLOGIC safety controller and the X20 Safe I/O. Programming safety functions for ACOPOSmulti devices with SafeMC is done in the standard development environment using SafeDESIGNER in B&R Automation Studio. Autonomous configuration of the SafeMC components and the embedded parameter chip allow quicker and easier configuration during service work.
