Patent number: 9377770Abstract: In a numerical control system in which a numerical controller and an I/O unit perform serial data communication through a communication line, a counter of the I/O unit starts time measurement with an input signal from an in-machine measurement device as a trigger and stops counting at the start of transmission of DI data. The I/O unit transmits a flag indicative of input of the input signal as a trigger and a value in the stopped counter to the numerical controller. Based on a time value measured by a timer and the counter value, the numerical controller calculates the time of input of the input signal.Type: GrantFiled: February 7, 2013Date of Patent: June 28, 2016Assignee: FANUC CorporationInventors: Yoshito Miyazaki, Hiroshige Ando

Patent number: 9377771Abstract: A numerical controller is chain-connected with a plurality of I/O units so that it transmits DI/DO signals to and receives DI/DO signals from the I/O units by master-slave communication. The numerical controller counts signals generated by a timer circuit up to a predetermined number and sets, from among the plurality of I/O units, an I/O unit with which transfer of the DI/DO signals is to be performed for each count value. The DI/DO signals of the set I/O units are transferred according to the count value.Type: GrantFiled: July 18, 2013Date of Patent: June 28, 2016Assignee: FANUC CorporationInventors: Yoshito Miyazaki, Hiroshige Ando

Patent number: 8259595Abstract: Each of the host transmitting/receiving blocks of a plurality of I/O units connected to a CNC reads the destination specification data and a diagnostic result bit each time the host transmitting/receiving block receives a signal packet from the CNC. When the diagnostic result bit indicates the execution of a diagnosis, the signal packet contains diagnostic DO data, and the relevant DO signal output terminal is short-circuited to the relevant DI signal input terminal to form a diagnostic loop. The diagnostic packet signal passes through the diagnostic loop, the external signal transmitting/receiving block, and the host transmitting/receiving block and returns to the CNC through the host transmitting/receiving block of an adjacent I/O unit closer to the CNC. The CNC analyzes the packet signal to determine whether each of the I/O units is operating normally or not.Type: GrantFiled: December 12, 2007Date of Patent: September 4, 2012Assignee: Fanuc LtdInventors: Kouji Hada, Hiroshige Ando, Hiroshi Noda

Patent number: 7977908Abstract: While a numerical controller is operating, an abnormality of a numerical control section is detected. In response to an abnormality detection signal, a motor deceleration stop control circuit of a servo section is actuated to perform speed control with a speed command “0”, thereby stopping a motor. If an actual speed of the motor becomes not higher than a preset speed, an off command signal for turning off a DO signal is delivered to a PMC section. In response to this off command signal, the PMC section turns off a brake control DO or all DO signals. Thus, a brake device that is attached to the motor is activated to brake the motor.Type: GrantFiled: February 28, 2008Date of Patent: July 12, 2011Assignee: Fanuc LtdInventors: Tsutomu Hamabata, Hiroshige Ando
