    摘要: A method of returning a movable machine element having a flat dog to a zero point includes advancing the movable machine element in the direction of the flat dog, stopping the movable machine element after a changeover signal (S.sub.D) produced by the flat dog is detected, reversing the direction of the movable machine element, moving the movable machine element a first predetermined distance (L) and stopping it after the changeover signal (S.sub.D) is received again, then moving the movable machine element in the opposite direction a second predetermined distance (l) shorter than the first predetermined distance (L) and stopping the movable machine element, thereafter moving the movable machine element at a low velocity and stopping it at an initial one-revolution signal of a servomotor, which operates the movable machine element, after the changeover signal produced by the flat dog is detected.

    摘要: An absolute position detecting system for a servocontrol system which has its operation controlled in accordance with a numerical control program. Resolvers 202 and absolute encoders 110 made rotatable with a servomotor 105, are set at a predetermined revolving ratio so that the absolute positions of operating axes may be detected highly accurately from the revolution outputs of the two. The detecting operations can be performed for the plural operating axes by using one detecting circuit commonly.

    摘要: An industrial robot arc control method subjects the position of a working member to circular-arc control by interpolation while controlling the target angle of the working member with respect to a surface to be worked, which working member is mounted on the wrist of an industrial robot. The industrial robot circular arc control method includes obtaining corresponding points (P1, P2 . . . ; Q1, Q2 . . . ;) of the tip and base of the working member (TC) at plural taught points for circular-arc control of the tip of the working member, which is mounted on a wrist (HD) of the robot, finding interpolated points of the tip and base of the working member by interpolation from the corresponding taught points, and obtaining command quantities for the motion axes of the robot from the interpolated points.
