Abstract: A control device includes: a casing; a communication board configured in a plate shape; a control board configured in a plate shape and having one side attached to the communication board; an amplifier board configured in a plate shape and having one side attached to the communication board and provided with a power module for driving an actuator of a robot; and a brake power supply unit disposed opposite the communication board across the amplifier board and configured to drive an electromagnetic brake of the actuator.

Abstract: A transit device that can suppress deterioration of a waveform of a transmitted signal and suppress noise superimposed on the signal while securing a required insulation distance is provided. The transit device is connected to a communication line connecting a first communication device and a second communication device and includes pulse transformers serially connected in the communication line, at least one first pulse transformer of the pulse transformers including an insulation transformer for insulating the first communication device from the second communication device and a common-mode transformer serially connected with the insulation transformer in the communication line for attenuating noise superimposed on the signal transmitted through the communication line, a second pulse transformer of the pulse transformers including an insulation transformer for insulating the first communication device from the second communication device.

Abstract: A servomotor control device includes a servomotor control circuit for controlling an inverter such that an alternating current is supplied to a servomotor when receiving a safety signal, and for controlling the inverter such that the alternating current is not supplied to the servomotor when not receiving the safety signal, and a servomotor monitoring circuit for stopping the servomotor by stopping transmission of the safety signal to the servomotor control circuit when determining to stop the servomotor, and for stopping the servomotor by disconnecting supply of a direct current to the inverter with a power source disconnect circuit and stopping the transmission of the safety signal to the servomotor control circuit when determining that at least one of the power source disconnect circuit, the safety signal, and the servomotor control circuit is not normal.
