Abstract
Die Erfindung betrifft einen getriebelosen Drehgeber mit zumindest einer Codierscheibe (20), die mit einer Geberwelle verbunden ist, einer Lichtquelle (22), einer Singletum-Lichtsensoreinheit (25), einer Multiturn-Lichtsensoreinheit (25), einer Auswerteeinheit (41, 42) zur Auswertung der Signale der Singleturn- und der Multiturn-Lichtsensoreinheit, und einer Energiespeichereinheit, die eine Schalteinheit, einen Oszillator (64) zur getakteten Steuerung der Schalteinheit und einen Energiespeicher (24) aufweist, wobei die Schalteinheit ausgelegt ist, die Auswerteeinheit, die Lichtquelle und die Multiturn-Lichtsensoreinheit mit dem Energiespeicher für eine netzunabhängige Energieversorgung zu verbinden. Der Drehgeber ist dadurch gekennzeichnet, dass eine Logikeinheit (44; 43, 45, 46) vorgesehen ist, der die Signale der Multiturn-Lichtsensoreinheit zur Auswertung zugeführt sind und die ausgelegt ist, die Schalteinheit anzusteuern, wenn ein gültiges Signal der Mutiturn-Lichtsensoreinheit vorliegt, um die netzunabhängige Energieversorgung zu unterbrechen.
