ABSTRACT:
A control system for stopping the operation of a sewing machine at a prescribed stop position includes a detector for generating signals indicative of detected positions of a needle of the sewing machine and a signal indicative of a detected speed of operation of the sewing machine. A control device stops the operation of the sewing machine in response to one of the signals indicative of the needle positions when the speed of operation of the sewing machine reaches a predetermined stop-ready speed. The control device has a selector for selecting either one of the options of detecting the stop-ready speed reached by the speed of operation of the sewing machine with a program stored in the control device and with one of the signals from the detector. The detector can thus detect stop-ready speeds for different sewing machine types without changing the program stored in the control device.
