Title:
METHOD FOR DISPLACING AN ELEMENT INTO A BLOCKED POSITION, SAID ELEMENT BEING OPERATED BY AN ELECTRIC MOTOR BETWEEN TWO BLOCKED POSITIONS THAT ARE DEFINED BY END STOPS
Document Type and Number:
WIPO Patent Application WO2001095470
Kind Code:
A3
Abstract:
The invention relates to a method for displacing an element into a blocked position, said element being operated by an electric motor within a defined path of displacement between two blocked positions that are defined by end stops. When the driven element is displaced to at least one of the two blocked positions, the driven element is slowed down before it reaches the mechanically defined blocked position. The invention is further characterized in that the electric motor is deenergized to slow down the driven element and is switched to a generator operation so that one can observe the decreasing speed of the rotor of the electric motor coming to a stop via the current signal that is generated while the electric motor comes to a stop. Depending on the value of the current signal detected in the generator operation, the electric motor is resupplied with current to finally displace the driven element to the blocked position.
