12 Software Update

HEIDENHAIN Corporation recommends making a backup of the 
control with the included USB Recovery Drive (684138-xx) before 
updating the NC software. Please refer to the manual included with 
the drive for the backup procedure.

Use a blank USB memory stick (512 MB or larger) to update the 
software. Do not use any memory stick with a smaller storage 
capacity.

The setup.zip file is required for updating the software. The file will 
automatically be recognized by the installation program of the control 
and must be contained in the root directory of the USB memory stick.



With the control software running, insert the USB memory stick 
containing the setup.zip file.



At software update menu screen, Press "1" and ENTER.

The software update will now be done automatically, taking 
approximately 10 - 20 minutes.

When the update is complete, it will prompt you to remove the USB 
drive and restart. At this time, remove the USB drive and press 
ENTER to restart.



After the system has restarted, it will start up normally to the control 
software.



You can now return to "System Maintenance -> Config" and change
