Abstract

PURPOSE: To provide a sewing machine driving device for not shifting a position even after stopping a sewing machine by turning the signal of a speed setting means to zero during the stoppage of the sewing machine. CONSTITUTION: When operation signals are turned on at the time t1 , for a speed setting means 33, by a speed command selection means 34, speed command signals 31 are selected and the sewing machine is rotated. Then, when the operation signals are turned off at the time t2 , the speed command signals 31 are switched to a positioning speed, position deviation output 32 is added to the speed setting means 33 by the speed command selection means 34 and positioning is performed at the time of reaching a target position to stop at the time t3 . After the time t4 , a speed zero command is added to the speed setting means 33 by the speed command selection means 34 and control is performed so as to turn the speed at the time of sewing machine stoppage to zero. Also, by a current command selection means 41, by switching to a second speed amplifier 39 after the time t4 , sound generated by a motor 2 at the time of the stoppage is reduced. On the other hand, in the case of manually rotating a sewing machine pulley 12, turning is made possible and also smooth turning is made possible.
