摘要： A method of controlling a motorized window treatment provides for continued operation of the motorized window treatment during an overload condition, a low-line condition, or an electrostatic discharge (ESD) event. The motorized window treatment is driven by an electronic drive unit having a motor, a motor drive circuit, a rotational position sensor, a controller, and a memory for storing the command. The controller stores the present position of the motorized window treatment in the memory each time the rotational position of the motor changes by a predetermined angle, such that a plurality of positions are stored in the memory. When the controller is reset due to an overload condition or ESD event, the controller recalls the desired position from the memory, determines the present position, and continues to drive the motor drive circuit in response to the command and the present position.

摘要： A method of controlling a motorized window treatment provides for continued operation of the motorized window treatment during an overload or low-line condition. The motorized window treatment is driven by an electronic drive unit having a motor, a motor drive circuit, and a controller. The controller controls the motor drive circuit to drive the motor with a pulse-width modulated signal generated from a bus voltage. The controller is operable to monitor the magnitude of the bus voltage. If the bus voltage drops below a first voltage threshold, the controller stops the motor or reduces the duty cycle of the pulse-width modulated signal to allow the bus voltage to increase to an acceptable magnitude. When the bus voltage rises above a second voltage threshold, the controller begins driving the motor normally once again. During an overload or low-line condition, the controller is prevented from resetting, while driving the motor with minimal interruption to the movement of the motorized window treatment.
