The VLT AutomationDrive 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 uninteded 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) orsafe bus communication (in extended manufacturing
plants). The coupling of Pilz safety relay and AutomationDrive is
perfect because AutomationDrive is approved for safety category 3
applications.
The electrical connection is extremely simple - just one wire.
AutomationDrive is approved for providing safe stop in category 3
installations without the need for feedback signals from the drive to
the safety relay.
