    摘要: A drive system for raising and lowering a window covering using a continuous cord loop that includes a motor with an associated encoder, device controller for the motor, a speed sensor, and proportional-integral-derivative (PID) layer. The device controller stores or receives a desired motor speed and generates a speed command signal to the motor. A closed-loop system applies a PID speed control algorithm to an error representing a difference between actual motor speed and desired motor speed. The PID layer uses the error to calculate a new output via PID control terms to automatically correct signals to the motor to achieve desired motor speed. A hembar alignment function automates positional control of a plurality of motor drive systems to synchronize raising or lowering of window covering shades with the shades in positional alignment. A system controller includes a time-counter indexed to a position scale to synchronize hembar alignment positional commands.

    摘要: A drive system for raising and lowering a window covering includes a motor, a driven wheel configured to engage a continuous cord loop, a controller for the motor, a sensor, and a housing. The continuous cord loop includes an endless loop of flexible material and one or more sensor targets disposed on the endless loop of flexible material. The housing supports a guide rail adjacent the driven wheel. The sensor is mounted to the guide rail and is configured to generate a signal indicating presence of each sensor target when the target is located in proximity to or in contact with the sensor. The controller is calibrated to store an initial position of each sensor target along the continuous cord loop, and is configured to receive the signal indicating presence of the sensor target and to identify a drift from the initial position during continuing operation of the drive system.
