DRIVE CONTROL DEVICE FOR FLUID PRESSURE CYLINDER
Problems: Provided is a drive control device for a fluid pressure cylinder that has good operability for expanding and contracting the fluid pressure cylinder in the vicinity of a stroke end. Solutions: A drive control device includes an expansion and contraction unit configured to expand and contract a fluid pressure cylinder in response to an operation of an operating body; a position detection unit configured to detect an expansion and contraction position of the fluid pressure cylinder; a speed detection unit configured to detect an expansion and contraction speed of the fluid pressure cylinder; a limiting unit configured to limit, according to the expansion and contraction position of the fluid pressure cylinder within a predetermined range from a stroke end and the expansion and contraction speed in a stroke end direction, the expansion and contraction speed of the fluid pressure cylinder in the stroke end direction by the expansion and contraction unit; and a stopping unit configured to stop expansion and contraction of the fluid pressure cylinder at a predetermined position by reducing an amount of a working fluid supplied to the fluid pressure cylinder as a distance of the fluid pressure cylinder from the predetermined position in the vicinity of the stroke end is shorter.
