摘要： A servo system in which the servo control circuit, servo amplifier and servo motor are connected with a single cable. The cable (87) between the servo control circuit (11) and the servo amplifier (2) includes a wire group for command signals from the servo control circuit (11) to the servo amplifier (2), and another wire group for feed back signal from the servo motor. The command signal wire group comprises three PWM signal wires (21 to 23), three ground wires (24 to 26), and one enable signal wire and other signal wires, the number of all of which is halved by use of an inverter in the power control circuit in the servo amplifier (2). The feed back signal wire group transmits the positional feed back signals from the servo motor (6) to the servo control circuit (11) through the servo amplifier (2). In such a way, the signal wire which is not used between the servo control circuit (11) and the servo amplifier (2) is used as a feed back signal wire which transmits the positional feed back signals from the servo motor (6). As a result, three cables which are conventionally needed to connect a single-axis servo motor to a servo control circuit are conveniently reduced to one cable.

摘要： This invention relates to a numeric control machine tool which requires fewer signal lines between an operation panel and a numeric controller. Matrix devices (S111, S112, ...) are disposed in matrix in each of switch matrices (1, 2, ..., n). Common signals (COM1, COM2, ..., COMj) are sent to common lines COM of the switch matrices (1, 2, ..., n). Data signals (DAT11, DAT12, ..., DAT2l) are sent from data lines (DAT1, DAT2) of the switch matrices (1, 2, ..., n). Similarly, input data signals (DATn1, DATn2, ..., DATnm) are sent from the data lines (DATn) of the switch matrices (1, 2, ..., n). Since the common lines COM are provided to the switch matrices (1, 2, ..., n) in this way, unnecesary common lines can be eliminated.

Means (1) receives instruction data output from a machine control board (40) serving as the input means, stores the data, executes the application program written by the operator, and outputs pulse signals for commanding the operations of machines, such as the movement of tools. Interpolating means (2) receives the pulse signals output from the means (1), outputs interpolation signals, and sends them to a shaft control circuit (15). The shaft control circuit (15) receives the interpolation pulses output from the interpolating means (2), issues speed commands of the shafts, and sends them to a servo amplifier (16). The servo amplifier (16) drives and controls a servo motor installed on a machine (30).

摘要： An axis control system of a numerical control apparatus comprising first and second microprocessors (11, 21) for interpolating the axes of dissimilar constitutions, and first and second interpolation signal generating circuits (17, 27) provided for the respective microprocessors to generate interpolation period signals. An output signal (DO) of the first microprocessor and an interpolation period signal (ITP1) of the first interpolation signal generating circuit are input to the second interpolation signal generating circuit (27). An interpolation period signal in synchronism with the first interpolation signal generating circuit (17) is generated based on the logic of these signals. When the interpolation period signals are brought into synchronism, the first and second microprocessors (11, 21) execute the interpolation of axes of respective axis constitutions.
