PROBLEM TO BE SOLVED: To provide a speed change control method which hardly produces a step-out of a motor, can reduce a time for acceleration/deceleration, can reduce a processing time required for start, can reduce a tact time, and can practice a multi-axes control at a low cost. SOLUTION: This acceleration/deceleration control method includes a process in which a speed change value is determined according to a data table corresponding to a value of [command speed - initial speed] and an acceleration/deceleration time; a process in which the division number of [command speed - initial speed] is determined according to [command speed - initial speed]/speed change value; a process in which the division number of the acceleration/deceleration time according to the division number of [command speed - initial speed]-1; a process in which a speed-changing interval is determined according to division number of acceleration/deceleration time/division number of acceleration/deceleration time; a process in which a speed obtained by adding the speed change value to the initial speed is determined as a starting speed and speeds, obtained by adding the speed change value to the previous speeds are determined as the speeds of the respective speed changes in an acceleration time; a process in which the speed is switched to the command speed when the speed reaches the command speed; and a process in which the command speed or the present speed is determined as a starting speed and speeds obtained by deducting the speed change value from the previous speeds are determined as the speed of the respective speed changes in a deceleration time. |
