Replacing the CompactFlash card
To replace the CompactFlash card, proceed as follows:
1. Ensure that the Control Unit is de-energized.
NOTICE
Destruction of the CompactFlash card
The CompactFlash card must only be inserted or removed when the power is off. Otherwise
there is a risk of data loss or damage to the card, which would prevent commissioning of the
drive.
• Only remove or insert the CompactFlash card when the power is switched off.
2. Withdraw the CompactFlash card from the Control Unit. Back up the data saved on it.
3. Copy the stored data of the previous CompactFlash card to the new original Siemens card.
Note
Invalid software key
The software key is associated with the serial number of the CompactFlash card. If you
overwrite the software key of the new CompactFlash card with the previous CompactFlash
card, the new CompactFlash card is not operational.
Consequently, use the software key of the new CompactFlash card.
4. Insert the new Siemens CompactFlash card.
