摘要： Disclosed is a controller for detecting need of maintenance, abnormal operation, etc. of a machine attributable to reduction of its strength caused by secular change. Acceleration detecting means are attached to driven elements that are driven by servomotors. Respective processors of axis control circuits for feedback-controlling the positions and velocities of the servomotors perform position and velocity feedback control processing for each position/velocity control period, thereby obtaining current commands, and output the commands to current loop processing. Detected acceleration values af are read from the acceleration detecting means. When the detected acceleration values af are not smaller than a threshold value as, an abnormality signal is outputted, whereupon an alarm is displayed and the machine operation is stopped. Since the accelerations of the driven elements are detected directly by the acceleration detecting means, abnormality of the machine, such as frequent vibration attributable to aging of the machine, collision of the driven elements with other objects, or breakage of parts, can be detected securely.

摘要： A servomotor driving controller capable of highly accurate machining, which prevents a quadrant projection upon change in the quadrant where machining is made. After the position deviation converges to zero by means of learning control, the velocity command or a difference between the velocity command and the commanded velocity which is the derivative of the position command is stored as velocity correction data. Until a predetermined time period elapses from when the sign of the position command is reversed, an amount of correction for each period of position loop processing is determined based on the correction data, and used to correct the velocity command.

摘要： A controller capable of preventing response delay and generation of vibrations attributable thereto during position control of a movable part of a machine having low rigidity. A motor for driving a machine having low rigidity is subjected to position and velocity loop control. Compensation amount Q1 proportional to command velocity obtained by differentiating a position command and compensation amount Q2 proportional to second-order differentiated command acceleration are obtained. Compensation amounts Q1 and Q2 are added together, thus obtaining a velocity offset amount Vof corresponding to a estimated torsion amount. A differentiated value of the velocity offset amount is multiplied by coefficient β to obtain a torque offset amount Tof. The velocity offset amount Vof is added to a velocity command Vcs obtained by position loop control 1. The torque offset amount Tof is added to a torque command Tc outputted in velocity loop control 2, and the result is used as a drive command to the motor. Based on the velocity and the torque offset amount Vof and Tof, a torsion amount between motor 3 and the machine is controlled. The machine position and velocity are controlled with accuracy by regular position and velocity loop control.
