SAFETY FUNCTIONS
ACC. TO EN 61800-5-2

Conventional safety controls are limited to logic processing or to reduced word processing of data. Safe drive monitoring, as required by the European Machinery Directive from the end of 2009, cannot be implemented with them. 

Our series, on the other hand, offer full future security. By means of safety functions for drive monitoring integrated in the firmware, the new tasks can be implemented quickly and efficiently. Regardless of the drive technology, our safety controllers offer all functions according to EN 61800-5-2 for drive monitoring and, in addition, practical function extensions.

Whether in single or multiple operation, whether simple inverter or high-quality servo drive, electric, hydraulic or pneumatic drive, the safety functions integrated in the firmware are easy to use and guarantee full future safety!
