摘要： A machine learning device includes a model data selection unit to select, under a change in ambient temperature of a manufacturing machine, a learned model for additional learning of a thermal displacement compensation amount in each axis included in the manufacturing machine with respect to an operation state of the manufacturing machine, and a learned model storage unit to associate and store a pattern of an ambient temperature change curve indicating a transition of a change in the ambient temperature of the manufacturing machine and the learned model that is learned under the change in the ambient temperature. Based on the ambient temperature change curve stored in the learned model storage unit, the model data selection unit selects a learned model suitable for the additional learning of the thermal displacement compensation amount in each axis included in the manufacturing machine with respect to the operation state of the manufacturing machine.

摘要： 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.

摘要： A numerical control device includes a CPU for outputting a position command value of a servomotor; an IC including a servo controller for outputting a current command value to an amplifier for driving the servomotor, and an I/O unit for inputting and outputting an external signal; a DSP for reading the position command value and performing control so as to move the servomotor to a position indicated by the position command value; and an inter-device communication path between the CPU and the IC. The IC includes an internal bus connected to a communication interface connected to the inter-device communication path, and the I/O unit; and an internal communication path for directly transmitting a signal between the servo controller and the I/O unit without passing through the internal bus.

摘要： 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.
