There are two options for replacing the device:
Option 1: The machine manufacturer only knows the serial number of the new inverter
● 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?
● The machine manufacturer goes online on the sample machine.
– deactivates the know-how protection, see Settings for the know-how protection
(Page 338)
– enters the serial number of the new inverter in p7759
– enters the serial number of the inserted memory card as reference serial number in
p7769
– activates the know-how protection with copy protection ("Copy RAM to ROM" must be
activated!), see Settings for the know-how protection (Page 338)
– writes the configuration with p0971 = 1 to the memory card
– sends the memory card to the end customer
● The end customer inserts the memory card and switches on 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).
Option 2: The machine manufacturer knows the serial number of the new inverter and the
serial number of the memory card
● 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?
● The machine manufacturer goes online on the sample machine.
– deactivates the know-how protection, see Settings for the know-how protection

– enters the serial number of the new inverter in p7759
– enters the serial number of the customer's memory card as reference serial number in
p7769
