Video: Machine safety solution is compact yet scalable

13 November 2020

Bosch Rexroth has introduced the ctrlX Safety system as a responsive and compact safety solution for the automation market. The scalable system can be used as required – from the drive-integrated SafeMotion solution in ctrlX DRIVE to the complete ctrlX SAFETY control.

The two components comprising ctrlX SAFETY — SafeMotion and SafeLogic — can be used independently or as an overall system. The hardware is extremely compact and, as a safety control, its graphical programming allows the required programs to be created quickly and easily without extensive training. The intuitive engineering interface, a documentation-supported user guidance and ready-made dialogs for the acquisition of acceptance-relevant information enable significantly faster engineering than conventional solutions. For more demanding applications, the hardware can be extended by additional I/O modules via the safe fieldbus. It has The platform promises high levels of safety thanks to fast reaction times and efficient engineering through graphical programming.

The exchange of safe I/O signals between the safety control and the SafeMotion on the ctrlX DRIVE is performed via ctrlX SAFETYlink.

SafeMotion is based on the modular drive system ctrlX DRIVE and has a scalable software. It is available as an entry-level version, with extended functions or for the highest requirements. “SafeMotion brings safety functions exactly where the motion occurs: to the drive. It is therefore unmatched in speed. At the same time, this system allows a purely drive-based safety solution to be implemented completely independently of the higher-level control system,” explained Steffen Winkler, vice president sales of the Business Unit Automation & Electrification Solutions at Bosch Rexroth.

The safety system allows for machine integration in the smallest installation space (thanks to shortened reaction times) and the integrated certified safety technology enables efficient machine acceptance. Once a safety solution has been planned, it can be integrated into different machine concepts without complex adaptation. As it supports the most common safe fieldbus protocols, ctrlX SAFETY can be integrated into almost any automation system, and modular safety strategies with safe cross communication can be realized.
