Once it is configured for autodetect, EasyMotion Studio/EasySetUp will determine the axis ID of the drive every time it is launched and every time the drive is powered-on. If the drive is successfully detected, then the status bar will display the Online message, the axis ID, the serial number and the firmware version of the drive.
