A motor control device includes a rectifier, a smoothing capacitor provided to a DC link, an inverter that power-converts DC power of the DC link and AC power of a motor side, an initial charging unit that charges the smoothing capacitor before motor driving start, a current detection unit that detects an AC current detection value of an input side of the rectifier, a current conversion unit that converts the detection value into a value corresponding to a DC link current, a current integration unit that outputs an integration value obtained by integrating the conversion value, an alarm output unit that outputs an alarm when the integration value is equal to or more than a first threshold value, a disconnecting unit that disconnects the AC power to the rectifier in response, and a protective unit that commands the disconnecting unit to disconnect the AC power when the alarm is output.
