- the steps E90, E170 for automatically determining the low and high end positions of the screen 2 can be implemented consecutively, in particular following the same step E50 of triggering the winding of the screen 2.
- Such a configuration method in which the determination of the low end position of the screen 2 and, optionally, the determination of the high end position of the screen 2 are implemented in a software way by the electronic control unit 15 of the electromechanical actuator 11, makes it possible to minimize the costs of obtaining and putting into service the motorized drive device 5 and to dispense with additional parts.
- the control method in operation of the driving device motor 5 includes a step E200 for triggering the unwinding of the screen 2, a step E210 for counting the position of the bar 8 of the screen 2, a step E220 for comparing a count value of the position of the bar 8 of the screen 2, determined in step E210, with respect to the count increment value S corresponding to the low end position of the screen 2 determined according to the configuration method, and a step E230 for determining whether or not the low end position of the screen 2 is reached by the electronic control unit 15 of the electromechanical actuator 1 1, as a function of the result of the comparison step E220 .
- the counting increment value S taken into consideration for determining whether or not the low end position of the screen 2 is reached, during the control mode of the motorized drive device 5, is a a value which is determined in step E90 of determination of the low end position of the screen 2 of the configuration method or in step E130 of manual modification of the bottom end position of the screen 2 the configuration process.
- the control method is implemented following the configuration of the motorized drive device 5, so as to determine, following the comparison, in step E220, a count value of the position of the bar 8 of the screen 2, determined during step E210, with respect to the counting increment value S determined, during step E90 or E130 of the configuration method, whether or not the end position of low run of the screen 2 by the electronic control unit 15 of the electromechanical actuator 1 1, depending on the result of the comparison.
- the detection of the low end position of the screen 2 by the electronic control unit 15 of the electromechanical actuator 11, during the unwinding of the screen 2, is accurate and reliable, of so as to be as close as possible to the breaking position of the arms 6 of the occulting device 3, in particular being independent of environmental factors from the motorized drive device 5, such as, for example, the outside temperature or the external humidity to the motorized drive device 5.
- the attainment of the low end position of the screen 2 is determined when the count value of the position of the bar 8 of the screen 2 is equal to the count increment value S determined according to the method configuration.
- the failure to reach the low end position of the screen 2 is determined when the count value of the position of the bar 8 of the screen 2 is different, in particular lower, than the value of the counting increment S determined according to the configuration method.
- the step E220 for comparing the count value of the position of the bar 8 of the screen 2 with respect to the counting increment value S is implemented periodically, as long as the result of the step E230 for determining whether or not the bottom end position of the screen 2 has been reached by the electronic control unit 15 of the electromechanical actuator 11 is different from the reaching of the end-of-travel position. bottom of the screen 2.
- step E220 for comparing the count value of the position of the bar 8 of the screen 2 with respect to the counting increment value S determined is implemented by means of the electronic unit of FIG. control 15 and, in particular, the microcontroller 9 of the electronic control unit 15.
- the determination of the first maximum value of the measured quantity by virtue of which the breaking position of the arms of the occultation device is detected, makes it possible to accurately determine the low end position of the screen.
- the low end position of the screen can be determined so as to be as close as possible to the breaking position of the shading device arms.
- the electric motor of the electromechanical actuator may be of the asynchronous or direct current type.
- the measured quantity I of the electric current flowing through the electric motor 16 may be different from its intensity. It can, in particular, be its tension.
- the method of configuring the motorized drive device of the home automation system can be implemented through a control point corresponding to a configuration tool.
