Abstract (en)
[origin: WO2006119787A1] The invention is directed to a method for controlling an elevatorr drive device for operating an elevator car, comprising the steps of providing a control circuit (2) for controlling the elevator drive device (3), and providing a pre-torque signal (401) to the control circuit (2), the pre-torque signal adapted as a control signal for holding the elevator car (10) still after a brake (32) for holding the car is released. A tracking error signal (203) derived from a difference between a command speed signal (201) and a detected speed signal (202) of the elevator drive device (3) is provided, moreover a load weight signal (501) of a load associated with the elevator car (10). The method further includes monitoring at least two tracking error signals and at least two related load weight signals (610 - 6139 over at least two operating runs of the elevator car (10), and controlling and adjusting the pre-torque signal (401), wherein the monitored signals (610 - 613) are provided as input signals for controlling and adjusting the pre-torque signal (401). Advantageously, elevator roll back and roll forward behaviour prior to the start of a normal run may be monitored, wherein the load weighing system setup may be effected automatically.
