Claims (9)
- PAT E NT KRAV1. Driv- og styresystem til en løfteport (1) med et vertikalt bevægeligt portblad (2), omfattende: en drivmotor (3), der kan forbindes med portbladet (2), og som er indrettet til at bevæge portbladet (2) vertikalt, en styreenhed (6) til styring af drivmotoren (3) og en effektreguleringsenhed (5) til regulering af drivmotoren (3), kendetegnet ved, at drivmotoren (3) er en synkronmotor og kan nedreguleres til en omdrejningshastighed på nul, styreenheden (6) er indrettet til ved indtræden af en stopbetingelse at styre drivmotoren (3) således, at dens omdrejningshastighed reduceres kontrolleret, og portbladet (2) dermed bremses motorisk, idet drivmotoren (3) er beregnet til ved en omdrejningshastighed på nul at levere et tilstrækkeligt drejningsmoment til at holde portbladet ved en øjeblikkelig position, og idet driv- og styresystemet endvidere omfatter en akkumulatorenhed, der er indrettet til at forsyne drivmotoren (3), styreenheden (6) og effektreguleringsenheden (5) med elektrisk energi i tilfælde af et strømudfald for at sikre funktionen med reguleret stop og holden i position.
- 2. Driv- og styresystem ifølge krav 1, kendetegnet ved, at akkumulatorenheden oplades med energi regenereret fra drivmotoren ved generatordrift.
- 3. Driv- og styresystem ifølge et af kravene 1 eller 2, kendetegnet ved, at styreenheden detekterer et strømudfald og starter en nøddrift.
- 4. Driv- og styresystem ifølge et af kravene 1 til 3, kendetegnet ved, at drivsystemet er udstyret med en positionsmelder.
- 5. Driv- og styresystem ifølge krav 4, kendetegnet ved, at positionsmelderen leverer aktuelle værdier for positionen, og at styreenheden ved farlige afvigelser i forhold til den forudbestemte bevægelseshastighed at indlede en reguleret bevægelsesafbrydelse.
- 6. Driv- og styresystem ifølge krav 1, kendetegnet ved, at styreenheden er indrettet til, når en forudbestemt undergrænse for akkumulatorenhedens restladning nås, at bringe portbladet i en sikker, ikke nedstyrtningstruet position via drivmotoren.
- 7. Driv- og styresystem ifølge krav 1, kendetegnet ved, at styreenheden er indrettet til, når en forudbestemt undergrænse for akkumulatorenhedens restladning nås, at sikre portbladet redundant mod nedstyrtning ved aktivering af en holdebremse.
- 8. Driv- og styresystem ifølge krav 7, kendetegnet ved, at styreenheden endvidere er indrettet til at overvåge en holdeposition ved aktiveret holdebremse ved hjælp af positionsdataene og ved afvigelse at foranledige en energitilførsel til drivmotoren med henblik på fastholdelse i den aktuelle position.
- 9. Løfteport med et vertikalt bevægeligt portblad (2) og et driv- og styresystem ifølge et af kravene 1 til 8.
