Abstract | A stepper motor may be controlled by a controller to provide extended revolution of a motor shaft while operating in a first mode and to allow a user to manually intervene with an intended position or rotation of the motor shaft while operating in a second mode. In some embodiments, the controller may adjust a torque applied to the stepper mode during operation of the stepper motor. The controller may reduce a torque applied by the stepper motor to a lower torque while the user intervenes with the intended position or rotation of the motor and increase the torque to a holding torque after the user intervention has ended. Thus, the controller may dynamically adjust a torque of the stepper motor in response to detection of the user intervention. |
