摘要： An object of the present invention is to provide a control apparatus for a robot in which the work efficiency is improved in the whole robot peripheral system including the robot, and in which considering the increase in the consciousness of safety such as the standardization of safety apparatuses, both the reliability of the safety circuit of the control apparatus for a robot and the ensuring of the safety are improved. By connecting, to peripheral devices outside the robot, each intermediate output signal line for extracting the operation signal or the emergency stop signal of each of the plurality of switches each assigned to a factor causing the stop of the robot, a factor to cause the stop of the robot body alone can be distinguished from a factor to cause the stop of both the robot body and the peripheral devices.

摘要： A robot controller capable of minimizing an increase in the tact time during work, reducing changes in joint axes of the robot, thereby providing the structure with long mechanical life. The robot controller i) stores a plurality of movement data formed of amount and time for movement; ii) checks whether a movement of a robot has acceleration exceeding a predetermined level by calculation on the basis of the stored movement data; iii) increases the time for movement of the corresponding movement data, the preceding and following data to the movement data, if the calculation indicates over-acceleration; and iv) controls the robot according to the time-increased movement data.

摘要： An acceleration generated when a tool tip of a robot moves straightly or turns a teaching point inward, is suppressed under a predetermined maximum acceleration so that the tool tip moves smoothly. From teaching point data including a moving instruction to specify a trajectory shape on the basis of a teaching point giving a reference based on which a tip portion of the robot moves, a moving speed instruction to specify a moving speed of the tip portion on the trajectory, and an allowable path error to specify a maximum value of an error between the teaching point and the trajectory, a realizable moving speed when the tip portion of the robot moves on the straight line trajectory is obtained, a deceleration rate with respect to the moving speed recorded in the teaching point data is obtained, a realizable moving speed when the tip portion of the robot passes the inside of the teaching point is obtained, a deceleration rate with respect to the moving speed recorded in the teaching point data is calculated, and those values are stored in the teaching point data. When the robot is operated, in accordance with the straight portion deceleration rate and the inward turning portion deceleration rate stored in the teaching point data, the moving speeds of the robot at the straight portion and the inward turning portion are reset.

摘要： An automatic offset adjusting apparatus for current detectors in a digital controller for a servo motor is constructed so that, when errors occur in offset correction values due to a temperature change and the like while the servo motor is in operation, an electrical angle detecting unit detects a ripple of the torque of the servo motor, on the basis of a ripple of a torque command value, and detects a first electrical angle, where the torque command value becomes maximum, and a second electrical angle, where the torque command value becomes minimum, based on an electrical angle signal of the servo motor, a judgement unit judges whether or not offset correction errors have occurred on the basis of a difference between the first and second electrical angles, and, if the judgement unit judges that the offset correction errors have occurred, a correction unit adds adjustment values for the offset correction values corresponding to the first electrical angle to the respective offset correction values to update the offset correction values, whereby the correction of the offset correction values is automatically carried out even while the servo motor is in operation, thereby preventing generation of the ripple of the torque of the servo motor.
