Corrective maintenance
9.2 Replacing inverter components
Option 2: The machine manufacturer knows the serial number of the new inverter and the
serial number of the memory card
1. The end customer provides the machine manufacturer with the following information:
– For which machine must the inverter be replaced?
– What is the serial number (r7758) of the new inverter?
– What is the serial number of the memory card?
2. The machine manufacturer performs the following steps online on the prototype machine:
– Deactivating know-how protection
– Enter the serial number of the new inverter in p7759.
– Enter the serial number of the customer's memory card as reference serial number in
– Activate know-how protection with copy protection. "Copy RAM to ROM" must be
– Write the configuration with p0971 = 1 to the memory card.
– Copy the encrypted project from the card to the associated PC.
– Send the encrypted project to the end customer, e.g. via e-mail.
3. The end customer copies the project to the Siemens memory card that belongs to the
machine, inserts it in the inverter and switches on the power supply for the inverter.
When powering up, the inverter checks the serial numbers of the card and when there is a
match, the inverter goes into the "ready to start" state.
If the numbers do not match, then the inverter signals fault F13100 (no valid memory card).
