Problems solved by technology

[0007] However, in order to control the driving of the actuator, in addition to the initially determined moving distance and moving time of the displaceable member, the user needs to calculate specific driving conditions (for example, the speed of the displaceable member, and the time related to the speed), This would result in a high workload for the user or human-induced calculation errors

Embodiment Construction

[0059] Hereinafter, the actuator drive control apparatus 10 and the actuator drive control method according to the present invention will be described in detail with reference to the accompanying drawings.

[0060] like figure 1 As shown, an actuator drive control device 10 according to an embodiment of the present invention is connected to an actuator 12 and a computer 14 and a PLC (Programmable Logic Controller) 15 via cables. The user executes control instructions from the computer 14 (PLC 15 ) to input data control commands or initiate driving of the actuator drive control device 10 , and accordingly, the actuator drive control device 10 performs control to drive the actuator 12 .

[0061] The actuator 12 includes a displaceable member 16 linearly displaceable according to driving control, a drive unit 18 for transmitting a driving force to the displaceable member 16, and a displacement for detecting a displacement amount of the displaceable member 16. Detector.

Abstract

An actuator drive control apparatus is equipped with a movement distance setting means for setting a movement distance of a displaceable member, a movement time setting means for setting a movement time, a target value calculating means for calculating a target value of a displacement amount or a displacement velocity of the displaceable member at an arbitrary timing based on the movement distance and the movement time, and a drive controller for generating driving power based on the displacement amount or the displacement velocity target value of the displaceable member and sending the drive power to an actuator.

Description

technical field [0001] The present invention relates to an actuator drive control apparatus and an actuator drive control method for moving a displaceable member equipped with an actuator to a predetermined position. Background technique [0002] There is known an actuator configured as a drive mechanism for displacing a displaceable member according to control from an actuator drive control device. The actuator drive control apparatus includes various control methods and circuits, etc., for operation according to desired (for example, see Japanese Laid-Open Patent Publication No. 09-308282 and Japanese Laid-Open Patent Publication No. 08-272422 patent) displaces the displaceable member. In this configuration, in order to enable highly accurate displacement of the displaceable member, detailed operations such as acceleration, constant speed, deceleration, etc. can be set. [0003] For example, in the speed command generating device disclosed in Japanese Laid-Open Patent Pu...
