    摘要： A method and a system are disclosed for preventing stepper motor control signals from being applied to a stepper motor drive circuit in order to stop a stepper motor when an interlock situation is present. A sequence of one or more control signals is generated by a motion control system and passed to one or more interlock logic gates connected in series. The interlock logic gates have an enable signal input which allows the control signals to pass through to the stepper motor drive circuit if the enable input signal is set to a logic level of “1”. On the other hand, the interlock logic gates will prevent the control signals from reaching the stepper motor drive circuit if the enable input signal is set to a logic level of “0”. The logic level of the enable input signal may be connected to a switch, relay, or an integrated circuit responsive to an interlock situation such as the opening of an access door.

    摘要： A method and a system are disclosed for adaptively controlling a stepper motor to produce a required torque output based on selection information provided by a sensor or a user/user interface which, in combination with a selector, selects a torque-related value. The selection information provided to the selector for selecting the stepper motor torque-related value may be, for example, the size or thickness of material being handled or the number of accumulated sheets for processing. The torque-related value is predetermined through experimentation and loaded into a lookup table stored in the memory of a motion control system board. The selected torque-related value is provided to a stepper motor driver which supplies the appropriate drive signal(s) to the stepper motor.

    摘要： In a mail inserter having an envelope movement mechanism to move an envelope into an insertion station and a feeder to move a pack of insert material into an insertion position so that the insert material can be inserted into the envelope, a linear array of optical sensing elements is used to determine the position of one edge of the insert material and another linear array of optical sensing elements is used to determine the position of one edge of the receiving envelope in order to make sure that there is sufficient end clearance between the insert material and the receiving envelope. A stepper motor is used to adjust the envelope position, if the end clearance is outside a predetermined range.
