Patent number: 11626828Abstract: A motor control system for a folding partition includes a data storage device and processing circuitry. The data storage device is configured to store a normal threshold profile to serve as a threshold for a measured current supplied to a motor to detect abnormal operation of the motor. The motor is configured to drive motion of the folding partition. The processing circuitry is operably coupled to the data storage device. The processing circuitry is configured to generate an adjusted threshold profile to serve as a threshold for the measured current supplied to the motor while moving the folding partition during a transition from an abnormal operational mode to the normal operational mode. The adjusted threshold profile is used for detecting additional abnormal operation of the motor. The processing circuitry is configured to generate the adjusted threshold profile by adjusting at least a portion of the normal threshold profile.Type: GrantFiled: June 25, 2021Date of Patent: April 11, 2023Assignee: Won-Door CorporationInventors: Duane O.
