Caution
Parameter download between different types of control units and of different firmware
versions is not recommended.
It is possible to download parameter sets from different CU types, however, as the
parameter sets might differ, the user is fully responsible for the consistency of the
downloaded parameter set.
Therefore, the customer has to confirm his responsibility in case of an automatic download
by acknowledging F0395.
During download of a parameter set from an MMC to the EEPROM of the Control Unit
CU240S (e.g. during serial commissioning) you have to note that the LEDs are flashing
correctly. If the Control Unit CU240S is in a fault state, the LEDs indicate this fault state with
higher priority than the download. It is not sure that the parameter set is downloaded
correctly.
Once an inverter with an appropriate parameter set is available, the parameter set can be
uploaded and in the next step downloaded into the new inverter via OP, STARTER or MMC.
The various interfaces are shown in the figure below.
