    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: 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”.

    摘要: An error decoding circuit comprises a syndrome computing circuit for computing a syndrome on a receive data, an error detecting circuit for detecting an error based on the syndrome, an error pattern computing circuit for computing an error pattern based on the syndrome, and an inverting circuit for performing an error correction of a receive data based on the computed error pattern. Only when there is an error in the receive data, based on the detection result of the error detecting circuit, a request signal for extension of a bus cycle is outputted to a bus master. On the other hand, if there is no error in the receive data, an inputted data is outputted to a data bus without correction. By so doing, the high speed operation of the data bus is executed.

    摘要: A transmission path delay is set in a shift setting register. A slave unit generates a PRE_ITP signal in response to a timing signal (ITP signal) issued by a master unit. The phase difference between this PRE_ITP signal and the ITP signal unique to the slave unit is loaded into a period modification counter. A timer corrects a reference value, outputs position/speed control period signals (SYN signals) and counts down the period modification counter with these SYN signals until the period modification counter reaches zero. Furthermore, the ITP signal unique to the slave unit is outputted every time a predetermined number of the SYN signals are outputted.

    摘要: Noise detection is performed by using the output of the phase comparator that the PLL comprises. The phase comparator outputs a signal that is based on the phase difference between the output of the voltage controlled oscillator and the reference signal. The phase difference reflects the effect of noise on the PLL and, in addition to the characteristics of the noise itself, such as the wave height value of the noise and the frequency component thereof, reflects the tolerance of the PLL to noise, whereby the level of risk that the system can actually be caused to malfunction can be judged.

    摘要: A controller has a plurality of modules connected to each other via buses. On the transmitter side of each module, detection/correction code generation circuit for address/command and detection/correction code generation circuits for each kind of data are switched over according to information to be transmitted by a transmitter selection circuit, and then the data is transmitted with ECC code attached. On the receiver side, a receiver selection circuit selectively switches over an error detection/correction circuit for address/command and error detection/correction circuits for each kind of data to detect and correct errors.
