Option 1: The machine manufacturer only knows the serial number of the new inverter
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?
2. The machine manufacturer performs the following steps online on the prototype machine:
– Deactivating know-how protection
Activating and deactivating know-how protection (Page 392)
– Enter the serial number of the new inverter in p7759.
– Enter the serial number of the inserted memory card as reference serial number in
p7769.
– Activate know-how protection with copy protection. "Copy RAM to ROM" must be
activated.

– Write the configuration with p0971 = 1 to the memory card.
– Send the memory card to the end customer.
3. The end customer inserts the memory card 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).
