A control system for controlling actuators comprises a central processor, a plurality of actuators, and a plurality of servo systems for controlling the respective actuators. Each servo system is operable, independently of the central processor, to control a controlled parameter (Y) in accordance with a reference value (R). The servo systems and the central processor communicate via a non-deterministic communications system. The central processor and the servo systems provide, to the central processor via the non-deterministic communications system, offset signals representing offsets (R−Y) measured by the servo systems between reference R and actual Y values of the controlled parameter. The central processor compares the offsets (R−Y) measured by the respective servo systems one with another.

A control device includes: a command generating unit that generates a command for a motor, a correction-amount calculating unit that performs correction-amount calculation processing for calculating a correction amount for the command on the basis of elastic parameters of elastic elements; and a stage detecting unit that detects the fact that a transition has been made from a first stage in which a driving force generated by the motor acts on the first elastic element to a second stage in which the driving force acts on the second elastic element via the first elastic element. When the transition from the first stage to the second stage is detected, the correction-amount calculating unit switches from first correction-amount calculation processing based on the first elastic parameter of the first elastic element to second correction-amount calculation processing based on the second elastic parameter of the second elastic element and the first elastic parameter.

A control device for a servo motor system is provided. The control device includes a segment parameter storage circuit, a velocity superposing circuit, a velocity transferring circuit and a pulse comparison circuit. The segment parameter storage circuit is electrically connected with the velocity superposing circuit and the pulse comparison circuit. The velocity transferring circuit is connected between the velocity superposing circuit and the pulse comparison circuit. The velocity superposing circuit updates a present velocity value according to a target velocity value and an increment. The velocity transferring circuit generates a PWM signal according to the present velocity value. The pulse comparison circuit transfers the PWM signal into a signal of a command pulse wave group and judges whether a pulse number of the PWM signal reaches a predetermined pulse number.

A servo system includes a communication cable which is disposed between a servo control circuit and a servo amplifier. A feedback cable and a power cable are each connected between the servo amplifier and a servo motor. The communication cable includes a command signal line from the servo control circuit to the servo amplifier and a feedback signal line. The command signal line includes three PWM signal lines instead of six PWM signal lines through the use of inverters in the servo amplifier, ground lines, an enable signal line, and other various signal lines. The feedback signal line transmits a position feedback signal, which is sent from the servo motor via the servo amplifier, to the servo control circuit. Thus, a number of signal lines between the servo control circuit and the servo amplifier become unnecessary and are used as feedback signal lines for transmitting position feedback signals from the servo motor. Therefore, three cables which have so far been necessary to connect a uniaxial servo motor to a servo control circuit can be simplified to one cable.

A computer numerical control (CNC) servo drive system includes a controller, a driver, a co-connection circuit, a first servo motor and a second servo motor. Users input a control command through the controller. The driver is connected to the controller, converts the control command into a drive signal, and outputs the drive signal. The co-connection circuit is connected to the driver and transmits the drive signal. A sum of maximum current values of the first servo motor and the second servo motor is not greater than a maximum current value of the driver, such that the driver can simultaneously drive the first servo motor and the second servo motor for operation.
