PM swap (CU externally powered)
Constraints: MMC with valid Parameter set plugged
● Swap detected, Parameter MMC -> RAM/EEPROM, inverter runs into F00395
● Confirmation for standard CU or acceptance test in case of fail-safe CU required
Constraints: no MMC
● Swap detected, Parameter EEPROM -> RAM, inverter runs into F00395
● If the parameters, already held in the EEPROM are ok there is no commissioning
necessary.
● Confirmation for standard CU or acceptance test in case of fail-safe CU required
Note
After a PM swap without MMC the parameter settings only stored in RAM will be lost
Successful swap
After a successful swap, F00395 will be displayed.
● In case of a standard CU a confirmation is necessary.
● In the case of CUs with fail-safe functions, an acceptance test must be performed.
Confirmation
On standard CUs the current parameter set needs to be checked and its correctness
confirmed by clearing F00395. This can be done via:
● Digital input or PLC signal (depends on the settings of P0700)
● Setting P7844 = 0.
● Via the key
on the BOP
WARNING
The user is responsible for ensuring that the parameters held in the CU are the correct
parameters for their application.
Acceptance test
On CUs with fail-safe functions it is necessary to do an acceptance test (refer to the "Fail-
safe functions" section in this manual). To clear F00395 on CUs with fail-safe functions the
following procedure has to be followed:
● P0010 = 30
● P9761 = safety password
● P7844 = 0
● Carry out acceptance test
