Abstract
There is provided a roller conveyor that has a function capable of specifying a failure part or a defective part. When a signal for executing a failure detection operation is transmitted from a host controller () to each zone controller (), each zone controller () immediately activates the corresponding motor-incorporating roller (). Then, after a certain time, the motor-incorporating roller () is stopped. A pulse interval thereafter is detected by a pulse interval monitoring program () to determine whether a delay phenomenon has occurred. The delay phenomenon is a phenomenon in which the pulse signal generation interval is temporarily extended.
