Method for controlling an elevator

A method for controlling an elevator comprising:

• a first step in which the car is on a landing with car doors open for loading and/or unloading the car;
• a second step in which it is determined whether the car doors are fully closed or the car doors are not fully open after the loading and/or unloading is completed;
• a third step in which the total actual axial mass FΣact hanging from the traction sheave is measured;
• a fourth step in which a stalling limit total minimum axial mass FΣmin hanging from the traction sheave is determined;
• a fifth step in which reopening of the car doors is checked, whereby if the car doors are reopened, then return to the first step, else, continue to the next step;
• a sixth step in which start of the elevator is permitted;
• and
• a seventh step in which the total actual axial mass FΣact measured in the third step is compared with the stalling limit total minimum axial mass FΣmin determined in the fourth step,
• whereby if the total actual axial mass FΣact measured in the third step is equal to or greater than the stalling limit total minimum axial mass FΣmin determined in the fourth step, then normal run of the elevator car to the next landing is permitted, else, the elevator is stopped.
