You have entered the command ENABLE ADW while in Adept Digital Workcell simulation mode. In response to this command V+ restarts the servos to account for any robot configuration changes that have made in the Adept Digital Workcell system. V+ is asking for confirmation before restarting the servos. If ENABLE ADW was entered on purpose to restart the servos enter "Y". Otherwise enter "N". See the topic "Communicating with the Controller" in the Adept Digital Workcell documentation for information about restarting the servos.
