    • A numerical control system with shortened communication paths to lower a cost of the system. A plurality of servo amplifiers for respectively controlling a plurality of servomotors are arranged separately from a numerical controller. Pulse encoders for detecting positions/velocities of the servomotors are connected to the numerical controller by optical cables forming a serial communication path in a daisy chain, via a branch unit. The servo amplifiers for driving the servomotors are connected to the numerical controller by optical cables in a daisy chain, via the branch unit. Since the communication path for transmitting signals from the pulse encoders connects the pulse encoders and the numerical controller without the servo amplifiers intervened in between, the communication path is not elongated even in a case of the servo amplifiers are located remote from the servomotors, to construct the system with a low cost.

    • A numerical controller and a servomotor control system, capable of axis control required in case of a communication failure in the control of servomotors driven by servo amplifiers connected to a plurality of serial buses.

The device comprises a plurality of communication control circuits for detecting respective communication failures of the serial buses and selecting means for selecting whether or not to notify the other communication control circuits of a communication failure, if any, of any one of the communication control circuits detected thereby. In the control of the servomotors driven by the servo amplifiers connected to the serial buses, an output of a servo amplifier connected to a serial bus that suffers a communication failure is reduced to 0 so that outputs to the servo amplifiers connected to the remaining normal serial buses can be maintained.

    • An analog amplifier performs control of a motor at the speed in proportion to a speed instruction (analog voltage) outputted from a numerical control device. The speed instruction (analog value) is converted into a digital value by an A/D converter and is then sent to a CPU. When the CPU judges that the received digital value corresponding to the speed instruction deviates from a predetermined range, the CPU stops sending out an enable signal, and sends out an emergency stop signal. As a result, the CPU stops electric power supply to the analog amplifier, and also invalidates the speed instruction sent to the analog amplifier 20, thereby performing control to make the speed of the motor become “0”.
    • 模拟放大器以与从数控装置输出的速度指令(模拟电压)成比例的速度进行电动机的控制。 速度指令(模拟值)由A / D转换器转换为数字值,然后发送到CPU。 当CPU判断出与速度指令相对应的接收数字值偏离预定范围时,CPU停止发出使能信号,发出紧急停止信号。 结果,CPU停止对模拟放大器的电力供给,并且使发送到模拟放大器20的速度指令无效,从而进行使电机的速度变为“0”的控制。
