摘要： 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.

摘要： 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 numerical controller has a plurality of serial buses to which the numerical controller and a plurality of servo amplifiers are daisy-chain-connected and controls servomotors connected individually to the servo amplifiers. 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.

摘要： A table containing correspondence between “n” and “m” is set in a control circuit of a servo control system so that the current command data in the m-th (m=1, 2, 3 . . . ) current command register is assigned to the n-th (n=1, 2, 3 . . . ) servo amplifier. When data is specified in this table to satisfy “n=m”, the current command data in the n-th current command register is passed to the n-th servo amplifier. When “m=1” is set for “n=1” and “m=1” is set for “n=2” in this table, the current command data stored in the first current command register is passed to the first and second servo amplifiers.

摘要： 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”.
