DRIVE ARRANGEMENT FOR DOOR OPERATOR
Method (100) for controlling a drive arrangement (200) for an automatic door operator (30) of an entrance system (10) having one or more movable door members (D1 . . . Dm), whereby the automatic door operator (30) is for causing movements of the one or more movable door members (D1 . . . Dm) between a closed position and an opened position, respectively. The drive arrangement (200) comprises a DC-motor (34) for driving the automatic door operator (30), a H-bridge (96) and a controller (32, 232) for controlling the drive arrangement (200). The H-bridge (96) comprises a first leg (A) and a second leg (B), the first leg (A) and second leg (B) both being connected to a first voltage supply line (97) and a second voltage supply line (98), the first voltage supply line (97) having a higher voltage than the second voltage supply line (98).
