Behaviour of the new version?
The above-named software version rectifies this functional restriction.
Which products are affected?
8400 StateLine SW ≤ V2.00
8400 HighLine SW ≤ V1.00
What happens?
If the frequency inverter is only switched on with control voltage (24 V) (230 V / 400 V supply remained switched off) the LU message expected is not generated. The frequency inverter indicates the 'Ready to Switch On' state.
When does the problem occur?
The problem occurs if the supply voltage (230 V / 400 V) is switched off and the control voltage (24 V) is switched on.
Possible diagnostics?
Check the DC-bus voltage (L-C00053)
Short-term measures/recommendations?
None.
Evaluation:
This function restriction is detected during commissioning.
