8.2.3 Replacing a frequency converter
With regard to the response of the frequency converter after a replacement it is necessary to
distinguish whether an MMC is plugged in the frequency converter or not.
Frequency converter without MMC
After replacement, the frequency converter signals the error F00395 – unless the application
ID for this slot is the same as the application ID of the slot from which the frequency
converter originates.
Frequency converter with MMC
After plugging in, the frequency converter will carry out an automatic download from the
MMC only if P8458 > 0 (see "Transfer of parameters").
After replacement, the frequency converter signals the error F00395 – unless the application
ID for this slot is the same as the application ID of the slot from which the frequency
converter originates.
WARNING
Replacement constraints
