    摘要: A numerical control system exchanges input/output signals between a numerical controller and an IO unit and the IO unit includes a first control unit that changes an idle signal output from the IO unit using an input signal as a trigger to a specific waveform pattern signal and when the specific waveform pattern signal is received, transmits the specific waveform pattern signal to a former side. The numerical controller includes a second control unit that outputs an interrupt signal when the specific waveform pattern signal is received.

    摘要: A drive control commanding unit is provided which, when plural such units constitute a system, can configure the system as a synchronous system which can conduct a synchronous operation free from synchronism deviation. The drive control commanding unit has an operation clock generator 9 which generates an operation clock signal, an interruption generator 11 which outputs an interruption signal at every cycle of the operation clock signal. There also is a station number setting unit 13 through which a station number indicative whether the drive control commanding unit is operated as a master or as a slave is set; a synchronous timing signal transmitter 15 which operates only when the unit is used as the master, and which outputs a synchronous timing signal on the basis of the operation clock signal; a synchronous controller 18 which operates only when the unit is used as a slave, and which outputs a synchronous operation starting signal on the basis of an error state signal indicative of a ready state of a synchronous operation, and a synchronous timing signal received from the master drive control commanding unit. A synchronous checker 22 judges whether the operation of a slave drive control commanding unit is synchronized with that of the master drive control commanding unit or not, and an error signal generator 24 outputs an error signal based on the error state signal.

    摘要: A method for limiting a working area of a CNC machine tool uses a servo controller for transferring a tool which periodically generates an interrupt signal to a main controller and the main controller periodically transmits position data to the servo controller according to an algorithm of a built-in interrupt routine. The algorithm of the interrupt routine comprises the steps of obtaining standstill position data by subtracting an accumulation value of output position data reflecting a predetermined acceleration/deceleration time constant from an accumulation value of target position data for every corresponding interrupt period, when the interrupt signal is input from the servo controller, and adding the subtraction result to current position data, and transmitting predetermined control data after comparing the standstill position data with predetermined boundary position data. Therefore, the working area of the machine tool can be controlled by software so that accurate numerical control can be continuously performed without causing physical impact to the system.
