Abstract: A flap to be identified is caused to move over the whole of its angular range of travel. The number of motor steps is counted during this movement, and the number of steps counted is compared with at least one pre-recorded information item corresponding to a particular flap or type of flap. The method is applicable to the checking of the correct fitting of actuator housings in an air-conditioning installation, or to the allocation of addresses to actuators connected to an information bus.

Abstract: During the actuation of the flap, the drive frequency of the stepper motor is reduced as a function of the requirements for torque delivered by the motor in order to shift the flap. To that end, information is continuously gathered representing the requirements for torque delivered by the motor in order to shift the flap, the drive frequency is reduced, if appropriate, in response to a detected increase in the torque requirements and, when the drive frequency is below a predetermined maximum frequency, the drive frequency is increased, if appropriate, in response to a detected reduction in the torque requirements. In that way, the power of the actuators can be limited while coping with momentary peaks in torque requirements.
