2.7.5 Coordinate system of the lathe
You specify the coordinate system of the lathe in the kinematics description.
The parameter MP_CoordSystem (in System/DisplaySettings/
CfgCoordSystem) is relevant for the simulation, graphic representation in ICP 
and for the help graphics. The following settings are possible:
 +X / +Z: Horizontal lathe—turning behind the center
 –X / +Z: Horizontal lathe—turning in front of center
 +Z / +X: Vertical lathe—turning to the right of center
 +Z / +X: Vertical lathe—turning to the left of center
2.7.6 NC software exchange on the MANUALplus 620
General 
information
 The setup.zip file is required for the software exchange. The installation 
program of the control automatically detects the file which must be stored 
in root directory of the data medium from which the update is run.
 A backup of the control's previous NC software is automatically created, 
while the software is being updated. The backup file is packed and stored 
on the memory stick. If the update is not completed successfully, your 
previous NC software version will automatically be restored. In addition, the 
complete update archive is automatically unpacked to the memory stick 
before installation. The memory stick must have enough free space for the 
backup and for unpacking the setup files. This is ensured by using a USB 
memory stick with a storage capacity of 1 GB.
 The NC software must be exchanged only by trained personnel.
 For exchanging the NC software, HEIDENHAIN provides a packed file 
with the NC software. For intermediate storage, the packed file is stored 
on a USB memory stick or a USB hard disk. Then it is installed on the 
control from the intermediate storage medium.
 HEIDENHAIN recommends making a backup of the control, for example 
with TNCbackup (included in TNCremoNT), before updating the NC 
software, see "Data backup" on page 149.
HEIDENHAIN recommends:
Use a USB memory stick (1 GB or larger) to exchange the software. Do not 
use any memory stick with a smaller storage capacity.
As a registered customer, you will receive the setup.zip file necessary for 
the update directly from HEIDENHAIN. 
To do so, please write by e-mail to filebaseteam@heidenhain.de.
