Replacing the Control Unit without data backup
If you do not backup the settings, then you must recommission the drive after replacing the
Control Unit.
Procedure
1. Switch off the line voltage to the Power Module and (if installed) the external 24 V supply
or the voltage for the digital outputs of the Control Unit.
2. Remove the signal cables of the Control Unit.
3. Remove the defective Control Unit.
4. Mount the new Control Unit on the Power Module.
5. Reconnect the signal cables of the Control Unit.
6. Switch on the line voltage again.

Replacing a Control Unit with active know-how protection
Replacing devices with know-how protection without copy protection
In the case of know-how protection without copy protection, the inverter settings can be
transferred to another inverter using a memory card.
Replacing devices with know-how protection with copy protection
The know-how protection with copy protection hides the inverter settings and also prevents
the duplication of the inverter settings.
If the inverter settings can neither be copied nor forwarded, a recommissioning is required
after inverter replacement.
To avoid the recommissioning, you must use a Siemens memory card, and the machine
manufacturer must have an identical prototype machine that it uses as sample.
There are two options for replacing the device:
