Device for controlling the stopping of a motorized shrouding product

摘要

Device for controlling the stopping of a shrouding product driven by an asynchronous motor having a phase-shifting capacitor (1) stopping the motor when the shrouding product encounters an abutment or an obstacle and utilizing for this purpose at least one operating parameter of the motor so as to detect the appearance of a resisting overtorque. This device furthermore comprises means (4) for detecting a dip in the supply voltage of the local network and means for disabling the control of stoppage when the supply voltage falls below a specified value and for as long as this voltage remains below this specified value.
