An elevator drive apparatus is described which includes a drive unit for driving an elevator car, a brake device for braking a motion of the elevator car, a detector for detecting an electrical operation amount of the drive unit, and a controller. The controller is configured to release the brake device, to compare the detected electrical operation amount with a threshold, and to apply the brake device when the detected electrical operation amount exceeds the threshold. In this way, it is ensured that a speed of the elevator car in case of a rescue situation is within a safety limit.
