Abstract
A motor control device includes a signal identifying unit and an overvoltage detecting unit. The signal identifying unit includes an optical isolator that converts an electrical signal supplied via a terminal to which an external device is connected and a switch that turns off a connection circuit connected to the terminal. The overvoltage detecting unit is configured to turn off the switch when a voltage applied to the connection circuit is greater than a threshold voltage.
