PROGRAMMABLE ELECTRONIC SEWING MACHINE AND CONTROLLER FOR PROGRAMMABLE ELECTRONIC SEWING MACHINE

The worker sets a programmable sewing machine in a program mode, manually operates the input section to input a target position D, and creates sewing data. A control unit drives X-and Y-axis motors according to a command value P determined according to the difference between the target position D and the current position E, and move a cloth holder toward target position D. If the cloth holder cannot be moved, or the current position E does not vary and the difference between the current position E and the target position D is equal to a predetermined value, or the difference is over the predetermined value, the control unit stops the drive output to the X-and Y-axis motors not to increase the difference, thereby preventing heating. Therefore, after the worker removes the cause that the cloth holder cannot be moved, the worker resumes input after the input of the target position D and can continue to create sewing data subsequently to the previously created sewing data.
