摘要： To precisely detect the position of a mechanically moving portion which is driven by a motor, restraining the effect of backlash. A position detector (3) produces a position detection pulse every time after a mechanically moving portion (2) driven by a motor (1) is moved by a predetermined amount. A counting means (4) counts the position detection pulses sent from the position detector (3), and a reading means (5) reads a value counted by the counting means (4) every time after a predetermined period of time. A cancelling means (6) cancels the content of the counting means (4) by a counted amount read by the reading means (5). A backlash amount storage means (7) stores a backlash amount of the drive system, and a moving amount calculating means (8) calculates a practica l amount of movement of the mechanically moving portion (2) every time after said predetermined period of time based upon the content stored in the backlash amount storage means (7) and the value read by the reading means (5). An integrating means (9) integrates the results calculated by the moving amount calculating means (8).

摘要： Es wird eine Methode aufgezeigt, nach der eine einfache Positionierung von endlos drehenden Rundachsen (W) ermöglicht wird. Dazu wird jeweils eine Teilungssollposition (T s ) bestimmt, die dann, wenn der positive oder negative Zahlenbereich einer zyklischen Zählstufe (Z) verlassen wir, korrigiert wird, indem die korrigierte Teilungssollposition von einer minimalen bzw. maximalen Teilungssollposition (T min ,T max ) ausgeht, die um einen Übertrag und gegebenenfalls um einen Korrekturwert (+K,-K) variiert wird.

摘要： A system for numerically controlling a device such as a machine tool employs a general-purpose motor (11) in a part thereof, instead of a servo motor. In this system, the current position of a shaft (10) which is driven by the general-purpose motor (11) is detected (14, 9) and is compared with a command value within an NC program. When the current position is close to the command position, a brake signal (MBR, BR) is output in order to apply a brake to, for example, the general-purpose motor (11), and the supply of rotational signals (MCW, MCCW) to the general-purpose motor (11) is inhibited to stop the general-purpose motor (11) at the command position.

摘要： An electrical motor system in which a microcomputer (11) controlled driver (39) monitors the real time operating parameters of the motor (1) to keep the real time operating parameters of the motor (1) in a range that is governed by limiting parameters, such as maximum temperature and maximum current, thereby allowing the microcomputer (11) to control the driver (39) in order to provide to the motor (1) optimum power on a moment to moment basis. In the illustrative embodiment, the driver (39) microcomputer (11), indexer (43), power supply (17) and encoder or resolver circuitry (21) are hybridized on at least one hybrid circuit, each circuit being attached to a heat sinking system (95), potted in a series of thermally conductive and EMI/RF insulating compounds, and are enclosed in a metallic enclosure (81) which is directly coupled to the back of the motor to form a compact, unitary device.

摘要： The number of signal lines is decreased between a machine tool (1) and a numerical controller (3), and the present position of a mechanical moving portion is correctly recognized at all times on the side of the numerical controller (3). Position detecting means (12) produces a detection signal whenever the mechanical moving portion has moved a predetermined amount, and serial data generating means (16, 17, 18, 19) generate serial data that represent the present position of the mechanical moving portion and the like. Switching means (13) sends out either the detection signal or the serial data onto the same signal line that connects the machine tool (1) and the numerical controller (3) together. Follow-up means (21, 22) reproduce the detection signal produced by the position detecting means (12) while the serial data are being produced, and control means (31, 20) send the detection signal reproduced by the follow-up means (21, 22) to the numerical controller (3) immediately after the serial data have been produced.

摘要： A system for returning to the point of origin, a mechanical moving part equipped with a dog. The mechanical moving part is, first, moved in the direction of the dog. When a switching signal (SD)caused by the dog is detected, the mechanical moving part is stopped and is reversely rotated. When the switching signal (SD) is received again, the mechanical moving part is moved by a first predetermined distance (L) and is stopped. The moving part is then moved in the opposite direction by a second predetermined distance$(1,3)$which is shorter than the first predetermined distance (L) and is stopped. The moving part is then moved at a slow speed. After the switching signal produced by the dog has been detected, the mechanical moving part is stopped by the initial one-turn signal of a servo motor which operates the mechanical moving part.
