PROBLEM TO BE SOLVED: To shorten the total cycle time of system by comparing an operating time calculated based on an operating distance indicated from a controller with a shortest operating time, and forming a speed pattern based on the shortest operating time if the operating time is shorter than the shortest operating time. SOLUTION: A shortest operating time memory 22 stores a shortest operating time decided based on natural vibration period of a mechanism to be divine. A reference speed pattern memory 23 stores a reference speed pattern decided based on a maximum torque of a used motor. A speed pattern calculator 21 calculates a speed pattern for commanding accelerating and decelerating characteristics of the motor. Here, the operating time is calculated based on the distance of an object to be driven command from a controller 20 and the reference speed pattern transmitted from the memory 23, this is compared with the shortest operating time transmitted from the memory 22, and a speed pattern is formed. |
