14 Reloading the NC Software Used

14.1 Introduction

It can be helpful for servicing to reload the NC software used on the machine on the iTNC 530
if data of the SYS partition were lost.
For example:
Each NC software version and each service pack installed are archived on the control's hard disk.
With the single-processor version of the iTNC 530, this is done in path SYS:\zip and with the
dual-processor version in path C:\Program Files\Install. These archives can be called on the
control as described in the following desciptions.
The NC software used can be downloaded from the states archives. The associated data are
extracted again. It might thus be possible to restore destroyed files on the hard disk.

machine
July 2010
HEIDENHAIN cycles were lost.
DSP errors are generated frequently that were obviously caused by a loss of data.
Messages are generated that refer to a loss of data.
Before loading again the NC software used, run a hard disk test for the SYS partition. The Test
for bad clusters must be activated. Contact a HEIDENHAIN service agency if you wish to
carry out this special hard disk test.
Note
Defective areas on the hard disk detected by the hard disk test are "disabled".
I.e., that these areas are not used any more in the event of a new loading of data.
Check which NC software version and which service pack is active on the control. Press the
MOD key.If the NC software number is followed by SP (e.g., 340490 04 SP6), a service pack
is active in addition to the NC software.
Write down the number of the NC software version and the service pack!
Note
First the NC software version is loaded again and subsequently the associated service pack.
If still possible:
Move machine to home position (axes, tool changer, tilting head, etc.).
Ask the machine operator!
Press EMERGENCY STOP.
Restart the control, do not acknowledge the Power interrupted message.
Note
HEIDENHAIN recommends backing up the control data before reloading the NC software
used. --> See "Backup on an External Data Medium" on page 13 – 192.
