Claims (2)

1. System (1) för att tillhandahålla en såkerhetsstoppfunktion hos ett motordrivet verktyg (2) anordnat att manövreras av en maskin (3), vilket system innefattar: ett motordrivet verktyg (2) innefattande en utgående axel (11), en el motor (10) anordnad att driva den utgående axeln (11), och en styrenhet (13) anordnad att styra driften av motorverktyget (2), varvid elmotorn (10) och styrenheten (13) år anordnade att drivas av en kraftkålla (14), och kånnetecknat av att systemet vidare innefattar en krets (17) anordnad att, som svar på mottagande av en utlösningssignal för att automatiskt försåtta elverktyget (2) i ett såkerhetsstopplåge, begrånsa effekten från kraftkållan (14) till elmotorn (10) och styrenheten (13) till en såkerhetsnivå som år tillråckligt låg för att elmotorn (10) inte ska kunna leverera ett vridmoment över en såkerhetströskel som år lika med noll, men åndå tillråckligt hög för att kunna driva styrenheten (13) på elverktyget (2). . System (1) enligt krav 1, varvid kretsen (17) år anordnad att hålla strömmen på nåmnda såkerhetsnivå tills en signal tas emot som indikerar återupptagande av ett normalt driftlåge för elverktyget (2), varpå kretsen (17) år anordnad att tillhandahålla en normal nivå av effekt från kraftkållan (14) till elmotorn (10), varigenom den elektriska motorn (10) kan leverera ett vridmoment över nåmnda såkerhetströskel.. System (1) enligt krav 1 eller 2, varvid nämnda utlösningssignal utlöses som svar pä en att en sensor (5) känner av att en människa (6) gär in i ett förutbestämt omräde (9) runt maskinen (3). . Systemet (1) enligt nägot av föregäende krav, varvid kretsen (17) har en strömingängssida (21) anslutbar till kraftkällan (14), och en strömutgängssida (22) anslutbar till elmotorn (10) och styrenheten (13). . Systemet (1) enligt nägot av föregående krav, varvid kretsen (17) innefattar: en lägströmssida (15) anordnad att överföra och begränsa strömmen frän kraftkällan (14) för att erhälla nämnda säkerhetsnivä av effekt, en högströmssida (18) anordnad att överföra ström frän kraftkällan (14) för att erhälla en normal effektnivä som gör det möjligt för elmotorn (10) att leverera ett vridmoment över nämnda säkerhetströskel, och minst en omkopplare (20) anordnad att selektivt rikta strömmen frän kraftkällan (14) till hög- och/ eller lägströmssidan. . System (1) enligt nägot av föregäende krav, varvid systemet (1) vidare innefattar maskinen (3) anordnad att manövrera det motordrivna verktyget (2). .
