Abstract

Fremgangsmåte og anordning for posisjonstyring av en nedi-hulls aktuator (1) sitt arbeidsorgan (12) hvor aktuatoren (1) er koplet til en griper (2) og anbrakt i et borehull (8) og hvor aktuatorens (1) arbeidsorgan (12) forskyves ved hjelp av en skrue-mutterforbindelse (20, 22) som drives av en motor (24), og hvor fremgangsmåten omfatter: - å kople en giver (28) til aktuatoren (1) hvor giveren (28) er innrettet til direkte eller indirekte å kunne måle skruens (22) dreievinkel; - å kople giveren (28) til en styringenhet (30) hvor styreenheten (30) er innrettet til å kunne motta en settverdi for hvor langt arbeidsorganet (12) skal forskyves, og på grunnlag av settverdien å styre motoren (24) til å dreie i ønsket retning inntil styreenheten (30) på grunnlag av signal fra giveren (28) beregner at settverdien er oppnådd; - å stille inn en settverdi; og - å følge med på at settverdien oppnås.
