Abstract
A control device includes a first controller, a second controller and a storage. The first controller performs safety control for a drive device. The second controller performs standard control for the drive device. The storage is accessible by both the first and second controllers and includes a first storage area and a second storage area. The first storage area stores data involved with the safety control, and the second storage area stores data involved with the standard control. The first controller accesses both the first storage area and the second storage area, and the second controller accesses the second storage area but is restricted from accessing the first storage area.
