ABSTRACT:
A control system for positioning a machine member in accordance with a set of predetermined instructions corresponding to a prescribed path of movement of the machine member includes first and second motor driving means operative in two mutually perpendicular directions to drive the machine member, pulse generating means to actuate the motor driving means, and a contour logic circuit to enable operation of the motor driving means in such a way that the machine member follows a staircase path closely conforming to the prescribed path. Drive of the first motor driving means is continuously maintained and drive of the second motor driving means is permitted only when required, then drive of the second motor driving means is continuously maintained and drive of the first motor driving means is permitted only when required.
