Abstract
A position of an object is controlled based on a distance YS until the object is stopped, a target velocity VS of the object, acceleration time ta for accelerating the object, deceleration time td for decelerating the object, velocity variation ΔVa within the acceleration time, and velocity variation ΔVd within the deceleration time, and a deceleration-start distance YSd. The distance YSd is a distance from where the object is made to start deceleration. The distance YSd is a sum of an integer part YSdq and a decimal part YSdr of the deceleration-start distance. Thus, management of decimal fractions is performed with respect to a pulse generation unit that outputs an output pulse corresponding to the velocity instruction.

A positioning control method for controlling the position of an object, based on a distance YS until the object is stopped, a target velocity VS of the object, acceleration time ta for accelerating the object, deceleration time td for decelerating the object, velocity variation ΔVa within the acceleration time, and velocity variation ΔVd within the deceleration time, wherein
- a deceleration-start distance YSd, being a distance until deceleration of the object is started, is determined as a sum of an integer part YSdq of the deceleration-start distance and a decimal part YSdr of the deceleration-start distance, to perform management of decimal fractions, with respect to a pulse generation unit that outputs an output pulse corresponding to the velocity instruction.
