Abstract: In oscillating an oscillating body, a control unit obtains a load torque due to the gravity acting on a drive motor at least at one angular position defined about an axis of rotation. The control unit calculates a specified maximum acceleration depending upon if the load torque Q is acting in a direction in which it hinders the acceleration or deceleration of the drive motor 15 or is acting in a direction in which it assists the acceleration or deceleration. An acceleration for the oscillating body is set so as not to be greater than the calculated specified maximum acceleration. The control unit adjusts the acceleration of the oscillating body depending upon the load torque of when the oscillating body 13 is accelerating or decelerating.

Abstract: An acceleration detection unit for detecting acceleration is mounted on a driven body. When a previous block is a positioning command, the system waits till the detected value of acceleration detected by the acceleration detection unit becomes equal to or less than a set value αs after the distribution of the movement command of the positioning command is ended. If the detected value of acceleration becomes equal to or less than the set value αs, the distribution of the movement command of the next block is started. Because the cutting feed, etc., is started after the detected value of acceleration has become equal to or less than the set value αs and the vibrations stopped, machining can be conducted with high accuracy.

Abstract: A method for changing a force control gain expressed as a ratio of force error to velocity command value in a control circuit performing a force control of a servo motor driving a die cushion disposed opposite to a slide in a press machine. The method includes: obtaining a difference between a displacement of the slide and a displacement of the die cushion in a state in which the slide and the die cushion collide with and are exerting force on each other; detecting the force when the difference of the displacements is obtained; calculating a spring constant of a structural portion based on a proportionality between the difference of the displacements and the force, when regarding the structural portion including the slide and the die cushion as an elastic structure; and changing the force control gain based on the spring constant using a fixed proportionality that exists between the force control gain and a reciprocal of the spring constant.

Abstract: Disclosed is a controller for restraining vibration of a driven element driven by a servomotor. The driven element driven by the servomotor is provided with acceleration detecting means. A correction value is obtained by multiplying a detected acceleration value detected by the acceleration detecting means by a coefficient. Correction is made by subtracting the correction value from a velocity command, and velocity feedback control is executed in a velocity control processing section to obtain a current command. Further, the servomotor is driven by current control processing, whereupon the driven element is moved. If the detected acceleration value is increased by vibration of the driven element, the velocity command is corrected to restrain the vibration, so that the vibration of the driven element can be restrained. Processing time can be shortened to restrain the vibration of the driven element by executing the correction of the velocity command based on the detected acceleration value for each velocity control period.
