PROBLEM TO BE SOLVED: To stably mold a high quality molded product by improving responsiveness of a speed control as quickly as possible in a molding machine for performing the speed control of a linearly movable member based on a broken line speed setting along the position axis. SOLUTION: The broken line speed setting along the position axis is converted into a position command pattern along the time axis represented by an operational expression of exponential function of the time and a speed command pattern along the time axis. The speed command for outputting to a servo amplifier is generated by generating the position feedback control command by the time and the speed feed-forward control command by the time based on that.
