Abstract: A diagnosis system is configured to diagnose an apparatus including a driver device. The system includes an acquisition unit configured to acquire waveform data indicating a waveform related to a current to be supplied to the driver device, and a determination unit configured to determine a condition of the apparatus. The determination unit is configured to obtain, based on the waveform data, a change caused by a component of a force in a particular direction applied to the driver device, and to determine the condition of the apparatus based on the obtained change. The diagnosis device determines the condition of the apparatus accurately.
