Abstract
A method for determining moving mass of a door system, actuated by a motor, wherein a) the motor electrical output, which is converted into mechanical output, is measured, b) the electrical output is summed during opening and/or closure, starting from the beginning of the actuation of the mass by the motor from initial rest until an end rest position is reached following completion of the actuation to determine energy losses, c) measurement of the maximum speed of the mass of the door system is measured during opening and/or closure, d) the electrical output provided by the motor from the initial rest position of the mass of the door system until achieving the maximum speed v thereof is summed, and the obtained energy value is reduced by the energy losses occurring up to this time point to determine the mass of the door system from the obtained kinetic energy.
