	The controller attempted to execute unexpected command. The following possible reasons are considered. 1. (If teaching was done with a personal computer.) WINCAPSII and controller version do not match. 2. The controller attempted to execute unsupported commands. 3. Data in the controller was somehow corrupted.
	In case of 1: Replace the version with the right one. In case of 2: Do not manually execute unsupported commands. In case of 3: Turn OFF the power switch of the controller and restart the operation.
