Safe-speed control solutions

Published:  13 August, 2009

The Allen-Bradley Guardmaster Minotaur Safety Relay 57P (MSR57P) dedicated safespeed monitoring relay and the Allen-Bradley PowerFlex 750 Series of AC drives offer manufacturers improved safety control and functionality. Both are designed for easy integration, flexibility and performance. They use the Rockwell Automation safe-speed control core technology that affords advanced safety control. This technology also will be available in future releases of Allen-Bradley Kinetix 6000 servo drives.

This advanced safety control helps reduce overall system cost, improve flexibility and increase productivity by allowing operators to perform maintenance and other tasks while a machine is still in motion. For example, with the safe-speed monitoring functionality, manufacturers can reduce and safely monitor the speed of their applications so an operator can safely remove jams and perform other similar maintenance work without completely stopping the machine. In addition, the improved safety torque-off option helps remove the need to power cycle the drive after a demand on the safety system, thus minimizing wear on the drive.

Safe-speed control offers easier configuration and can be used across multiple platforms. Whether integrated or dedicated platforms, safe-speed control provides users with flexibility to achieve the level of control needed - whether in an upgraded or retrofitted application.
