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： 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： An amplifier (unit) linked via a daisy type serial bus sends a transmission start signal SC and then sends the local data DATAn. If data from an amplifier at the downstream side is not received before transmission of the local data DATAn is completed, the delimit of the data from each amplifier is changed by adding an idle time data TIDD.

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： 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.
