摘要： PURPOSE:To always perform molding at the injection speed at the time of the molding of a good product regardless of the response characteristics of an actuator controlling a hydraulic cylinder by correcting the indicated speed pattern at the time of injection molding corresponding to the difference between the actual injection speed at the injection position of an injection cylinder and the injection speed of the speed pattern at the time of the molding of the good product. CONSTITUTION:A fundamental pattern memory means 11 stores the injection speed at the time of the molding of a good product corresponding to the signal of a position detector 8 detecting the injection position of an injection cylinder. A correction means 12 calculates the deviation of the injection speed calculated on the basis of the signal from the position detector 8 by a speed calculation means 10 and the injection speed stored in the funcamental pattern memory means 11 corresponding to the signal from the detector 8 and corrects the indicated speed pattern stored in an indicated speed pattern memory means 15 corresponding to the magnitude of the deviation. This corrected speed pattern is read by a speed forming means 4 to perform injection molding. The same control can be performed even at the time of dwelling control or weighing plasticization.

摘要： PURPOSE:To perform control according to an indicated speed pattern regardless of the response characteristics of an actuator controlling a hydraulic cylinder by correcting the indicated speed pattern at the time of injection molding on the basis of the deviation of the actual injection speed at the injection position of an injection cylinder and an indicated speed and injection acceleration. CONSTITUTION:The indicated speed pattern corresponding to the injection position of an injection cylinder is written in an indicated speed pattern memory means 11 and a speed pattern memory means 12. A speed calculation means 10 calculates an injection speed on the basis of the signal of the position detection means 8 of the injection cylinder and an acceleration calculation means 16 calculaters injection acceleration. A deviation calculation means 13 calculates the deviation of the calculated injection speed and the indicated speed at the corresponding position stored in the memory means 11 and a learning means 17 corrects the speed pattern stored in the memory means 12 from the injection acceleration and the speed deviation. A speed forming means 4 reads the corrected speed pattern to perform injection molding. The same control can be performed even at the time of dwelling control or weighing calculaters.

摘要： PURPOSE:To improve the positioning accuracy in an AC motor with a brake by controlling the brake by considering the overrun amount in response to the rotating speed and the acceleration of an electric motor with a brake. CONSTITUTION:An output in response to the rotating position of a rotational shaft 1a of a motor 1 is generated from a rotary position sensor 3, and a position converter 4 outputs an electric phase displacement. The rotating speed and the acceleration of the motor 1 are outputted by a speed detector 5 and an acceleration detector 6 by the phase displacement. Overrun amount predicting means 7 decides the predicted overrun amount by using the speed data and the acceleration data detected. This predicted overrun amount is inputted to a compensating calculator 11, and a brake driver 14 is driven on the basis of the compared result of the output with the output of a stopping position setter 12. The operation of the brake 2 is controlled by the brake driver 14.

摘要： PURPOSE:To embody an accurate positioning control responsing appropriately to a sudden load variation or the like by accomplishing an overrun compensatory control of a real time responsing to the detection speed at the present point of time. CONSTITUTION:An overrun quantity predictive means 28 is provided with a memory means 26, which memorizes beforehand a predictive overrun quantity data OVR in response to various speeds, and using the data, which is detected by a speed detection means 24 and responses to the moving speed of a piston rod at the present point of time, as an address data, the predictive overrun quantity data OVR responsing to the present speed is read from the memory means 26 real-timely. Thus, as a constitution to perform overrun compensation of a target value or a detection position constantly on real-time, an accurate overrun compensation responsing to the load variation actually gained when a cylinder is driven, can be accomplished. Therefore, an accurate positioning control can be performed even for a sudden load variation.

摘要： PURPOSE:To carry out positional control for positioning a fork part precisely at a desired rack without previously providing a running count dog or the like at a position where a movable carriage for an automatic warehouse comes to a stop. CONSTITUTION:A movable carriage for an automatic warehouse moves with any of various loads being set on its fork part. Drive wheels provided to the movable carriage run the movable carriage in a predetermined direction while they receives the dead weight of the movable carriage and a load from cargo or the like. A torque is given to the wheels from a running motor. A first position detector detects a rotational position of the running motor, and outputs a first detection signal. An auxiliary wheel for detecting a travel distance, which rotates in association with the running of the movable carriage, is attached to the carriage so that it makes contact with the surface of a running path under a predetermined load, irrespective of the load. A second position detector detects a rotational position of this auxiliary wheel, and outputs a second detection signal. A fork part is moved up and down by an elevating motor. The third position detector detects a rotational position of the elevating motor, and outputs a third detection signal. The position and speed control means controls the rotational positions of the running and elevating motors in accordance with the first, second and third signals so as to precisely position the fork part at a desired position.

摘要： PURPOSE:To alter synchronization conditions at an arbitrarily moving position and to improve flexibility of control by providing input means for arbitrarily inputting data for setting the synchronization conditions of a multi-shaft servo motor under the synchronization control of the servo motor for a robot or the like. CONSTITUTION:In a multi-shaft servo control for a robot or the like, an input circuit 26 for setting synchronization conditions at an arbitrary position. In the circuit 26, combinations CM1-CMm of shafts and synchronous/asynchronous conditions SY1-SYm are set. A microcomputer 20 calculates shaft-component speeds, residual moving distance and residual moving pattern according to conditions from the input circuit, and sends moving position command values x1(t)-xn(t) representing the moving positions of unit time of a moving pattern to servo controllers 10-1-10-n. The controllers 10-1 to 10-n control shafts 1-n according to a command value x(t). Thus, the synchronization conditions are arbitrarily altered to improve flexibility of control.
