Abstract
An encoder includes a measurement target and circuitry. The measurement target includes an absolute pattern and is rotatable. The circuitry is configured to generate, via a processing scheme, a signal representing an absolute position of the measurement target based on the absolute pattern. The circuitry is configured to detect, based on the absolute pattern, whether the measurement target rotates or not. The circuitry is configured to change the processing scheme based on whether the measurement target rotates or not.
