When the rotation direction of a motor is determined by a connection determination unit not to match a rotation command, the phase sequence of a current detection signal and the phase sequence of a voltage command are changed by a phase sequence change unit, or the positive/reverse polarity of an encoding signal outputted from an encoder is inverted by the phase sequence change unit, whereby the rotation direction of the motor controlled by a motor control device can match the rotation command.
