Abstract: A motor driving device capable of reliably detecting a malfunction in the performance of a heatsink. The motor driving device includes a heat generating element, a heatsink, an electric power detecting part for detecting a consumed power of the heat generating element, a temperature detecting part for detecting a temperature of the motor driving device, a temperature change calculating part for calculating, as a detected valuation, an amount of change in the temperature within a predetermined time, a reference determination part for determining a reference amount of change in the temperature based on the temperature and the consumed power, and a temperature change judging part for comparing the reference amount of change with the detected amount of change, and judges whether the detected change is different from the reference change.

Abstract: A testing device performing a worst case scenario test includes a machine learning device and the machine learning device observes data representing a test item and data representing an operation state and specifications of a manufacturing machine as state variables representing a current state of an environment. Further, the machine learning device acquires determination data representing a suitability determination result of an operation state of the manufacturing machine obtained when the test item is executed, and performs learning by using the state variables and the determination data in a state where manufacturing machine operation state data and manufacturing machine specification data are associated with test item data.

Abstract: A motor controller comprises: a motor driver arranged at a housing attached to a machine support; fan motors and arranged in or outside the housing; and a control unit. The motor driver drives motors. The fan motors blow cooling air for cooling the interior of the housing. The CPU includes a machining mode selection unit allowing selection of at least either a first machining mode of machining a machining target finely or a second machining mode of machining the machining target more roughly than in the first machining mode. If the first machining mode is selected, the machining mode selection unit exerts control to change the rotation numbers of the fan motors and so as to reduce vibration to be transmitted from the housing to the support column.

Abstract: A detachment tool of the present invention is a tool for detaching a device attached to a wall portion. The detachment tool includes a member in which a first through hole and a second through hole are formed, a first screw that fixes the member to the device while inserted into the first through hole, and a second screw that pushes the wall portion while inserted into the second through hole. The first through hole is a threaded hole that screw-engages with the first screw or an unthreaded hole. The second through hole is a threaded hole that screw-engages with the second screw. According to such a configuration, the detachment tool in which operationality in detachment is good, flexible adaptation to a space can be made, and force applied in detachment is also easily managed, and a motor drive device provided with the same can be provided.

Abstract: A cell controller includes a plurality of sensors for detecting the state of a plurality of manufacturing machines, a state storing unit for storing the state of each manufacturing machine, a breakdown information acquiring unit for acquiring breakdown information of each manufacturing machine, an input unit for inputting recovery operation information when each manufacturing machine stops, a recovery operation information storing unit for storing the recovery operation information of each manufacturing machine, and a correlation data generating unit.

Abstract: To provide a mounting fixture for a motor driver and a method of mounting the motor driver. A mounting fixture is used for mounting a motor driver on a power magnetics cabinet. The mounting fixture has a rod-like shape of a smaller diameter than multiple mounting holes of the motor driver. For mounting of the motor driver by fixing the mounting holes and multiple screw holes of the power magnetics cabinet with screws, the mounting fixture is inserted in advance into the mounting hole and the screw hole. The mounting fixture is fixed in any screw hole of the power magnetics cabinet. The position of the mounting hole of the motor driver is determined using the mounting fixture. The motor driver is fixed to the power magnetics cabinet with the screws.
