Control Techniques Unidrive M Series SI-Safety module for Unidrive M series

The SI-Safety module enhances the safety capability of Unidrive M for the protection of end users. The module also increases machine productivity with safety features which reduce the frequency of machine power-downs. Ensuring machines achieve stringent safety standards, SI-Safety can reduce machine size and cost by removing the need for external safety PLCs and other components.

• Increase productivity: SI-Safety minimises downtime as its functionality enables a machine to slow-down or stop, removing the need to power-down the machine after interruption.
• Enhanced user safety: Features including Safe Stop and Safe Operating Stop dramatically increase end user safety, as well as safe machine operation with Safe Limited Speed and Safe Limited Position.
• Achieves the highest safety level: SI-Safety is approved by TUV as meeting SIL3, the highest safety level attainable for industrial electrical components according to functional safety standards as IEC 61800-5-2.
