PROBLEM TO BE SOLVED: To provide an electronic cam control method capable of smoothly continuing acceleration or the like at a displacement point between a synchronized control section and a non-synchronized control section without generating vibration or the like. SOLUTION: This control method of an electronic cam using a servo motor has the synchronized control section for executing control for moving a control object at a constant speed and the non-synchronized control section for executing control for moving the controlled object from the end position of the synchronized control section to the start point of the next synchronized control section. The control in the non-synchronized control section uses a fifth-order function for position control of the electronic cam, a fourth-order function for speed control of the electronic cam and a third-order function for acceleration control of the electronic cam are used, whereby movement of the electronic cam at transition points where the non-synchronized control section is changed over to the synchronized control section and vice versa is smoothly controlled.
