4.1 Integratedprotectionmechanisms
Therelayconformstothefollowingsafetycriteria:
} Thecircuitisredundantwithbuiltinselfmonitoring.
} Thesafetyfunctionremainseffectiveinthecaseofacomponentfailure.
4.2 Operation
Thespeedmonitorcanindependentlymonitortwoaxesforstandstill,speedanddirection
ofrotation.Thespeedmonitorsignalsthestatusofthemonitoredvaluestothebaseunit.
Dependingonthesafetycircuitloaded,thevaluescanbetransferredfromthebaseunit,
e.g.toarelayoutputonthesafetysystem.Incrementalencodersand/orproximitydetectors
canbeusedtorecordthevalues.
