PURPOSE:To make a positioning stably operably without a residual vibration, for many positions indicated, by means of controlling the pulse motor by the combination of a plurality of groups into which drive pulse trains, for the positioning operation, are divided. CONSTITUTION:The group of drive pulse train given to make an acceleration to a certain speed and a deceleration from said speed to make a stopping, and a plurality of groups of drive pulse train given to make only several steps foward from the stop position and to make a stopping, are provided. The pulse motor is controlled by the former group of pulse train when the steps, defore a position to be made positioning, number above the constant value, and by the latter plurality of pulse train groups being combined when the steps number below the constant value. |
