Behavior of the frequency inverter when replacing components
Components should be replaced by the same type and the same version
To ensure maximum plant availability, the Control Unit and the Power Module can, when
required, be replaced by a unit of the same type and the version without having to
recommission the drive.
Note
Message F0395 indicates that components were replaced. In this case, before switching on,
you should check the system functions.
Replace the control unit with the same time and the same version
- With automatic parameter download (without recommissioning the system)
The prerequisite in this case is that the frequency inverter is operated with a memory card
and the setting p8458 = 1 or 2 (parameters are automatically downloaded from the memory
card). The frequency inverter is parameterized using the automatic parameter download and
message F0395 can be acknowledged.
- With manual parameter download (standard commissioning)
Parameters are not automatically downloaded if there is no memory card or with the setting
P8458 = 0. If a valid parameter set is available, then the frequency inverter is parameterized
by manually downloading this parameter set (from the memory card, Operator Panel or PC)
and message F0395 can be acknowledged.
Note
A valid parameter set is a parameter set that matches the type and software release of the
Control Unit and that has been adapted to fit the particular application.
