A fan unit is detachably attached on a side face of a housing, a heating element is housed in the housing, and the fan unit includes a fan configured to be detachably attached to the fan unit. The fan unit is configured to detachably support the fan so that when the fan unit is attached to the housing, directions in which the fan is attached to and detached from the fan unit are made different from directions in which the fan unit is attached to and detached from the housing.

Fan unit

A controller is detachably attached to a back face of a display device. The controller includes: a housing; a control unit housed in the housing and configured to control the display device; a connecting part configured to electrically connect the control unit to the display device; a fan configured to cool the control unit; and a fan attaching structure provided on the housing and configured to detachably attach the fan to the housing.

Controller

A display-equipped controller includes a display device, a first junction configured to electrically connect the display device and a main board, a radiator disposed opposite from the display device with respect to the main board, an attaching structure attaching the main board and the radiator to the display device, a support structure disposed between the display device and the main board and configured to detachably support a control board, and a second junction configured to electrically connect the main board and the control board supported by the support structure.

Display-equipped controller

A numerical control device includes a multicore CPU for outputting a position command value of a servomotor, an ASIC including a servo controller, which outputs a current command value to an amplifier for driving the servomotor, and another processor, and a DSP for reading the position command value and controlling the servomotor such that the servomotor moves to a position indicated by the position command value. The CPU and the ASIC are connected through a plurality of serial interfaces.
