A rotary electric machine control device for a rotary electric machine having winding sets with coils includes: an inverter for each winding set; a power source relay for each inverter; a terminal voltage detector detecting a terminal voltage of each coil; and a controller including an inverter controller, a relay controller and an abnormality determination unit. Each winding set and a corresponding inverter provides a system. When the rotary electric machine is driven using a normal system: the relay controller controls the power source relay to cut off power supply from a power source to the inverter in an abnormal system; the abnormality determination unit specifies a short-circuited location based on the terminal voltage in the abnormal system; and the inverter controller corrects a command value related to control of the inverter in the normal system according to a specified short-circuited location.
