It can achieve steady and smooth acceleration and deceleration of the elevator by adjusting the voltage or current of the motor according to the load and running direction of the elevator. In the proportional multi-point ramp modulator of an elevator, multiple ramp points are usually set, which correspond to the acceleration and deceleration process of the elevator in different speed ranges. By adjusting the position and slope of these ramp points, precise control of the elevator speed can be achieved.
