PURPOSE:To obtain the movement output of a cam in smooth motion by performing servocontrol over respective electric motors according to the target movement extents and basic axial speeds of respective cams obtained by setting data on the start angles, end angles, movement distances, and acceleration/deceleration angles of respective cam movement outputs. CONSTITUTION:A setting/display device 4 sets the start angle S, end angle E, movement extent L, and acceleration/deceleration distance (angle) alpha of each cam movement output. Then, a target position LP corresponding to the basic axial angle of the cam movement output is computed from the movement quantity VL per unit angle of a basic axis at the time of a stationary speed computed previously by a computing element 5 and the acceleration/deceleration movement quantity alphaL per basic axis unit angle at the time of acceleration or deceleration. This target position LP is transmitted to cam output position controllers 71-yn by a transmitting circuit 20 together with the basic axial speed V inputted from a speed computing element 3 after being held in a register 19. Then, a voltage command is outputted to servo-amplifiers 81-8n on the basis of the target movement quantity LP and basic axial speed V and a position loop is so formed as to obtain the cam movement extent set by the setter display device 4.
