Danfoss FC 302 Industrial Drives

 The VLT Automation Drive FC 302 comes standard with safe stop functionality suitable for category 3 installations as defined by EN 954-1.  This feature prevents a drive from starting accidentally. This is crucial for applications where preventing unintended starts are of vital importance.  The FC302 terminal 37 can be used as 'safe coast' for this purpose - the stop function satisfies stop category 3 EN 60204-1.  Expensive and bulky external components can be omitted, wiring simplified, and down-time minimised with this solution.  The safety signals can be transferred via discrete signals wiring (in compact machinery) or safe bus communication (in extended manufacturing plants).  The coupling of Pilz safety relay and Automation Drive is perfect because Automation Drive is approved for safety category 3 applications.
The electrical connection is extremely simple - just one wire.  Automation Drive is approved for providing safe stop in category 3 installations without the need for feedback signals from the drive to the safety relay.
