Active dynamic braking solution for an elevator system

An elevator drive unit of an elevator system, wherein the elevator drive unit comprises:

• a motor inverter connected to stator windings of a hoisting motor of the elevator system, wherein the motor inverter has high-side switches and low-side switches;
• and
• a drive controller;
• wherein the drive controller of the elevator drive unit is configured to cause the elevator drive unit to perform:
• detect a dynamic braking situation,
• obtain speed data representing a speed of an elevator car, and
• activate an active dynamic braking operation for dynamically braking the movement of the elevator car, if the obtained speed data indicates that the speed of the elevator car reaches a predetermined monitoring speed level, wherein the active dynamic braking operation comprises that the drive controller is configured to operate the motor inverter by switching the high-side switches and the low-side switches of the motor inverter in a controlled manner so that the rotating field is generated in the stator windings of the hoisting motor for dynamically braking the rotation of the hoisting motor and thus the movement of the elevator car.
