PCT No. PCT/DE95/01364 Sec. 371 Date May 5, 1997 Sec. 102(e) Date May 5, 1997 PCT Filed Oct. 5, 1995 PCT Pub. No. WO96/11321 PCT Pub. Date Apr. 18, 1996A control system for an electrical motor drive for moving a door between two end positions. The two end positions are detected by the control system, and an increment detector associated with the motor drive reproduces the movement cycle of the door. A stop associated with the motor drive marks an end position of the door that corresponds to the open position thereof. This open position is treated as a reference point. A pulse storage device is set to a specific value at this reference point and initiates the beginning of a pulse sequence to reproduce movement of the object between the end positions. The pulse sequence is compared for coincidence with pulses produced by the increment detector upon movement of the door into the opposite end position that corresponds to its closed position. |
