    • In a numerical control unit capable of driving a motor at a feed speed designated by a feed speed-designation dial, there are provided a potentiometer for generating a DC voltage proportional to the amount that a feed speed-designation knob is turned and an AD converter for converting the DC voltage output from the potentiometer into a digital quantity, the AD converter output being read out by a main processor section. The circuit construction can be markedly simplified as compared with the conventional circuit construction employing a voltage-controlled variable oscillator.

    • A loading system for a numerical controller which employs both a main processor and a sub-processor to ease the load on the main processor. The loading system transfers a control program stored in a nonvolatile memory to a RAM using a loading program which is stored in a ROM incorporated in the sub-processor, whereby the circuit arrangement is simplified and the cost of hardware is reduced. At the time of starting the numerical controller, the main processor reads out a loading program from the ROM of the sub-processor and transfers it to the RAM for storage. The loading program thus transferred is executed by the main processor, by which a control program stored in the nonvolatile memory is transferred to the RAM, completing the loading operation.

    • 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.

    • In a master unit, clock signals from a clock are counted by a counter, and clock data is generated. This clock data is outputted to a slave unit by a driver, and stored in clock data storage memory. The slave unit stores clock data received by a receiver in the clock data storage memory. A processor for a program controller of the master and slave units starts up, and executes the synchronized operation of an operating program of axes that are synchronized on the basis of clock data stored in the clock data storage memory. It is also possible to commence operation of an axis under other conditions without relying on clock data. If override is applied to clock data, override will apply only to an axis that is synchronized and operated in accordance with clock data.
