The reversing motor,which is controlled by two power relays,can be rotated in both directions as shown in the figure beiow.When the motor is mechanically combined with a lead screw,the rotary motion is converted to a linear one,such as the one moving lef tor right on the worktable in the layout.The desired direction of rotation is selected via the two STAFIT buttons,respectively.The limit switches LS1 and LS2,located at the two extreme motion limits,ensure 1-rqtf we forget to stop the movement of the worktable,then it will stop automatically, and the mechanism of the layout will not be destroyed.Draw the circuit of automation.
