To learn at least one actuating position of reference of an installation for actuating

摘要

An actuating mechanism for a gearbox (10) consists of an actuator (12) which is given displacement and rotation by the combined effect of a first motor (26) and eccentrically mounted rod (36) and a second motor (46) acting through a sleeve (54) and pin in groove (58, 56). When a projection (14) arrives at a stop (24) a high frequency minimal amplitude alternating current is applied and this establishes the true end stop position which is captured
