A machine learning device includes: a training data acquisition unit configured to acquire multiple pieces of training data each including insulation resistances of a servomotor at the beginning and the end of a certain period and time-series data indicating conditions of the servomotor in the certain period; and a learning model generating unit configured to perform a supervised learning using the training data to thereby generate a learning model.

Machine learning device, learning model generating method, insulation resistance estimating device, and control device

A system includes a communication circuit provided in at least one of multiple devices that are connected to a control device in a predetermined connection relationship. The control device includes: a signal transmitter designating, as a destination, one of the devices provided with the communication circuit, based on the connection relationship, and transmitting a call signal to the device designated as the destination; a receiver circuit wirelessly receiving a recall signal, which is transmitted in response to the call signal; and a determination unit determining that the control device and the device designated as the destination are connected in the connection relationship when the receiver circuit receives the recall signal. The communication circuit wirelessly transmits the recall signal to the control device when the device provided with the communication circuit itself is designated as the destination and when the device provided with the communication circuit itself receives the call signal.

System for controlling a plurality of devices using a CNC device

A motor driving amplifier and a numerical controller are connected to each other via communication to configure a numerical control system. The numerical controller includes a numerical control unit, a motor control unit, and an amplifier interface unit. Furthermore, a motor control processor included in the motor control unit is a multi-core processor.
