摘要： PURPOSE:To simplify the production of a positioning program by correcting and positioning the target position of only the indexing position to which the correction is commanded with the positioning deviation obtained from an external positioning action and therefore correcting other indexing positions just by a single positioning action. CONSTITUTION:The target position is set for the indexing position of a movable shaft of a machine tool, etc., by a target position setting means A of a position control device. Then the movable shaft is positioned by an external position means B. At the same time, the deviation between the present position of the movable shaft positioned by the means B and the target position set by the means A in response to said present position of the movable shaft is set as the correction value of an indexing position obtained by a correction value setting means C. In addition, an indexing position is set at a corrected indexing position designating means D for correction of the set target position. Then the position of the indexing position designated by the means D is corrected by the value set by the means C and delivered by an indexing position correcting means E.

摘要： PURPOSE:To cause a coordinate system, which controls a positioning position, to be one and to easily grasp the present position by providing a data storing means, a correcting register, an initial value setting means, a correction quantity setting means, a correction commanding means and a target position setting means. CONSTITUTION:A microprocessor 1 to receive a command from a sequence controller 20 inputs initial correction quantity from a data input device 3 at an initial setting step and sets the initial correction quantity to a correcting register CQR. Next, a selection point number in an NCD area is inputted and the correction quantity of this number is added and subtracted at a correction quantity setting step. Then, the correction quantity is stored in the register CRQ. After that, it is decided whether this value is in a use limit or not. When the value goes over the limit, a target point number in the NCD area is inputted and operation is moved to a correction commanding step. Then, it is decided whether there is a correcting flag in this number or not. When there is the correcting flag, the value of the CRQ is added to this value at a target position setting step and stored in a target position register OPR. After that, positioning control is executed until the value of a present position register APR goes to be the value of the OPR.

摘要： PURPOSE:To attain the investigation before and after an abnormality occurs by storing the hystory of the constant period of respective types of numerical data prepared during the action, updating memory contents at a constant time interval, detecting an abnormal signal and after an updating action is continued for a constant time, stopping the updating of the hystory of the numerical data. CONSTITUTION:Respective types of numerical data generated in the action of a numerical controller are successively stored into a storing means and the hystory for a constant time is formed. The formed memory contents are successively updated at a constant time interval by an updating means. Here, when the generation of the abnormal signal of the numerical controller is detected by a monitoring means, after a constant time updating action is continued after detection, the updating of the history of the numerical data is stopped by an updating stopping means, and therefore, the numerical data for each constant time before and after the generation of the abnormal signal at the numerical controller are stored. Thus, the passing contents of the device internal data when a device abnormality occurs can be investigated.

摘要： PURPOSE:To eliminate the unstableness of a servo system and to present the occurrence of noise by securing synchronism between the control of a positioning device done for fixed time and the detecting cycle of the absolute position of an absolute position detector. CONSTITUTION:The timing with which the present position of a movable stage 10 via an absolute position detector C is controlled accurately to a 2ms cycle by a real time clock RTC20. Thus the interruption signal S2 to be applied to an MPU1 is also set accurately at 2ms and the control timing with which the MPU1 calculates the following deviation and outputs the speed signal S1 is set accurately at 2ms. This control timing has a delay just by a constant time to the detection timing. Therefore the follow-up deviation is fixed when the interpolated control target value has its change at a fixed speed. Thus the speed of the stage 10 is also fixed and therefore the unstableness of a servo system is improved.

摘要： PURPOSE:To use ball screws of various pitches by calculating moving quantity in each pulse of a servomotor, causing the target position command and the position of a movable stand to be one to one and positioning the movable stand according to the target position command. CONSTITUTION:A machine tool is activated and a calculated position number is read from a sequence controller 50. Then, a target position OP of a table 40, which corresponds to the number, is retrieved. The retrieved target position is transformed to a control target position COP by an expression I and outputted to a servocontroller 20 and a servomotor 41 is driven. In order to display the absolute position of the table 40, an output E of a detecting device 45 is read and transformed to an absolute position DOP for display by an expression II. Then, the absolute position is externally displayed by a data input / output device 13. After that, it is investigated whether the control target position COP is equal with the target position OP or not. When the positions are equal, processing is finished. Thus, the input / output device 13 can make the absolute position of a table to be displayed and the absolute position of the table 40 correspondent one to one.

摘要： PURPOSE:To prevent the hunting for calculation and to stabilize the positioning control by providing the 1st calculation area set centering on the target positioning position together with the 2nd calculation area smaller than the 1st area. CONSTITUTION:A speed detector 12 is attached to an output shaft of a servo motor 9 to detect the moving speed of a movable stage 10 and sends the feedback signal to a drive circuit 8. The positioning data is previously supplied to a positioning data table PDT set in a RAM4 via a data input device 3. The 1st calculation area A is set centering on the target positioning value 0 together with the 2nd calculation area B smaller than the area A. A calculation end signal is outputted when the detected absolute position of a movable shaft enters the area B. Then the calculation signals are continuously outputted until the absolute position gets out of the area A after a calculation signal is once delivered. As a result, the calculation signals have different ON/OFF switching positions and therefore the hunting can be avoided with these calculation signals and the positioning control is stabilized.
