7.1 Behaviour of the Inverter when replacing components
Replacing the Inverter
To ensure maximum plant availability, the Inverter can, when required, be replaced by a unit
of the same type and the version without having to recommission the drive.
Replace the Inverter with the same time and the same version
- With automatic parameter download (without recommissioning the system)
The prerequisite in this case is that the Inverter is operated with a memory card and the
setting P8458 = 1 or 2 (parameters are automatically downloaded from the memory card).
The Inverter is parameterized using the automatic parameter download.
- 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 Inverter is parameterized by
manually downloading this parameter set (from the memory card, IOP or PC).
Note
A valid parameter set is a parameter set that matches the type and software release of the
Inverter and that has been adapted to fit the particular application.
Replace an Inverter by the same type
- Same power rating
If you replace an Inverter by the same type and the same power, then re-parameterization is
not required.
- Same format, higher power rating
If you replace an Inverter by one of the same type and the same format, however with a
higher power rating, then re-parameterization is not absolutely necessary. However, it is
possible that the open-loop control accuracy is therefore reduced.
- Lower power rating
If you replace an Inverter by one with the same type and with a lower power rating, then the
Inverter must be re-commissioned.
