Abstract: A sewing machine having a motor drive operating in response to a controller to rotate in forward and reverse rotation directions. A jogging angle may be set and the drive operated automatically for rotation in forward and/or reverse directions as a function of various operating conditions so that the needle is stopped in an optimum position for piercing a material.

Abstract: A drive control apparatus for a driven machine is designed to easily check which of a plurality of parameters indicating the control characteristics of the driven machine have been changed from their factory-set initial values. Initial parameter values are stored in a list in a first memory and current parameter values are stored in a second memory. When a display request is given, the initial values of parameters stored in the first list in a control section are compared to the current values of the parameters stored in nonvolatile memory. The identity of the parameters that have been changed from their initial values are displayed on a liquid crystal display. Also, the stored initial value list is displayed.

Abstract: A detector is provided for a sewing machine wherein light transmitting/shielding discs are mounted coaxially on a shaft of the sewing machine and sandwiched between light receiving and light transmitting optical fibers positioned along opposite side portions of the disc assembly and leading to a processing module section. The detector is able to detect a plurality of positional settings of the sewing machine as well as additional settings without imposing undue stress on the light transmitting optical fibers since the optical fibers remain linear. A power indicating light, connected to the processing module section via an optical fiber, ensures that there is minimal electrical interference with the operation of the detector.

Abstract: A sewing machine control device for controlling the drive of a sewing machine. The sewing machine control device is provided with a monitoring device having a display device for displaying data to identify the direction of rotation and abnormal conditions of the sewing machine.

Abstract: A sewing control system for controlling the speed of rotation of a sewing machine in which in a first embodiment, a rotation transfer ratio operation is inhibited during the time that slip occurs. According to a second embodiment, the rotation transfer operation is initiated only when the number of revolutions of the motor shaft is higher than a predetermined value. In a third embodiment, slip is prevented by not outputting a speed instruction which is not steeper than a predetermined gradient. In a fourth embodiment, when an abnormal condition is detected, the rotation transfer ratio is reduced in order to reduce the speed of the motor, thereby assuring the safety of an operator.
