Abstract
A cable system A includes a cablefor connecting a base deviceand a travelling body, a reel devicemounted on the travelling body, a motor controllerfor controlling a motorof the reel device, and a rotary encoder(rotation sensor) for detecting rotation of a reel. The motor controllerbasically makes the motorfree, when the reelis rotating in an unreeling direction, and basically applies a rotational torque in a reeling direction to the reel, when the reelis rotating in the reeling direction. Furthermore, even if the reelis rotating in the unreeling direction, if an unreeling speed of the cableexceeds a travelling speed of the travelling body, the rotational torque in the reeling direction is applied to the reel. Slackening of the cableis thereby prevented.
