Abstract:
A control arrangement of an elevator includes a safety gear, an over speed governor with a rope which is connected to the safety gear, a stopping device for generating an actuating force to the safety gear, and a drive unit for driving the elevator apparatus. In order to facilitate easy and efficient maintenance, the control arrangement includes a controller for controlling a triggered sequence to involve activating of the stopping device for braking with the safety gear, and controlling the drive unit to drive the elevator apparatus during braking with the safety gear until the safety gear stops the elevator apparatus.
