6.1 Behavior of the frequency inverter when replacing components
Frequency inverter
214 Operating Instructions, 08.10. 2008, t.b.d.
Replace a Power Module by the same type
- Same power rating
If you replace a Power Module by the same type and the same power, then re-
parameterization is not required and you can acknowledge message F0395.
- Same format, higher power rating
If you replace a Power Module by one of the same type and the same format, however with
a higher power rating, then re-parameterization is not absolutely necessary and you can
acknowledge message F0395. However, it is possible that the open-loop/closed-loop control
accuracy is therefore reduced.
- Lower power rating
If you replace a Power Module by one with the same type and with a lower power rating,
then then drive must be re-commissioned.
Replacing different components or version
If you replace different components (e.g. Profibus CU for Profinet CU) or components with
different software releases, then the drive must always be re-commissioned.
Questions that can arise in conjunction with replacing components:
● How do I create a valid parameter set?
When commissioning, you can create a valid parameter set either using the
commissioning softwareSTARTER (Page 58) or using the Operator Panel (Page 71).
● Which options are available for saving a valid parameter set? You can save a valid
parameter set either on the memory card (Page 77) or on the computer (Page 58) that
you use for commissioning with STARTER.
● How do I load a valid parameter set into my frequency inverter?
From the memory card when the frequency inverter is powered-up or by manually
downloading a parameters set either from the memory card (Page 78) or from the PC
(Page 58).
