    摘要： The proposed digital device for command and control of a tool translation and rotation, in particular a drilling tool (30), includes a first stationary motor (1), which is a digitally commanded brushless servomotor, for operating motion transmission means (3), and a second motor (2), which is likewise a digitally commanded brushless servomotor, rigidly connected to said motion transmission means (3) and moved, by the latter, to translate along an operation direction (L), in order to set the tool (30) in rotation (ω) by a chuck (4). The device (D) includes an electronic central unit (20) for digital processing and programming of data, which is interfaced with the first stationary motor (1) and with the second movable motor (2), and which can command synchronously the first stationary motor (1) and the second movable motor (2) and can control and change the operation mode of the second movable motor (2), in order to adjust immediately the rotation (ω) of the tool (30). The electronic central unit (20) can control and change immediately the extension, direction and speed (S1, S2) of the second movable motor (2) translation along the operation direction (L) by means of the motion transmission means (3), in relation to the hardness of a layer of material to be drilled by the tool (30), and of the composition of the same layer of material, as well as of the depth of the hole to be made therein.

    摘要： A servo controller carries out tandem control in which one driven body (4) is driven by a plurality of motors (1,2). Each motor (1,2) is provided with a position control section (11,21), a velocity control section (12,22), a current control section (13,23), a current amplifier (14,24), and a velocity detector (17,27). This tandem control is carried out by using a velocity integrator sharing unit (5) for equalizing integral values of integration elements of the velocity control sections (12,22). The same position command is inputted to control systems for the plurality of motors (1,2) to undergo tandem control. The velocity integrator sharing unit (5) keeps the integral values of the integration elements of the velocity control sections (12,22) substantially equal.

    摘要： A servo controller capable of driving a single movable member by two motors with high loop-gain setting to obtain a quick response. A servo controller includes two position controllers associated with respective motors and a damping controller. Each of the position controllers has a position control section to output a velocity command based on an identical position command from a host controller and a position feedback value from an associated position detector, a velocity control section to output a current command based on the velocity command and a velocity feedback value from an associated velocity detector, and a current control section to output a voltage command based on the current command and a current feedback value from an associated current detector. The damping controller outputs a current command correction value for compensating an interference between the two motors based on the velocity feedback values from the velocity detectors for the two motors. The current command correction value is added to or subtracted from the current command in the position controller for one of the two motors and is subtracted from or added to the current command in the other position controller for the other of the two motors.
