Abstract
To improve production efficiency while maintaining stability of an operation of a robot arm. A dust position determination unit determines whether there is a read error based on a read result of a detection head of an encoder. In a case where the dust position determination unit determines that there is a read error, an error determination unit judges in which region, among an allowable region and a non-allowable region, the read error occurs. In a case where the read error is judged to occur in the allowable region, the error determination unit continues an operation of the robot arm.
