Abstract
When a command radius r of a circular interpolation control exceeds a threshold value, a computer computes a speed limit for the circular speed at which the acceleration becomes constant. When the command radius r of the circular interpolation control is less than or equal to the threshold value, the computercomputes another speed limit for the circular speed at which rωor rωbecomes constant, where ω is the angular frequency. The computer performs the circular interpolation control by safeguarding the circular speed from exceeding one of the speed limits in accordance with the command radius r of the circular interpolation control.
