Abstract
A motor control angle sensor includes a sensor that outputs a signal according to driving of a motor, an arithmetic processing unit, a motion history temporary memory unit, and a motion history storage unit, wherein the arithmetic processing unit generates position information data containing a position of the motor acquired based on the signal output from the sensor and a time when the position is acquired, repeats processing of storing the generated position information data in the motion history temporary memory unit, and, when an abnormality is sensed or a signal reporting an abnormality is received from an external apparatus, stores the position information data stored in the motion history temporary memory unit in the motion history storage unit.
