Eliminated from:
StateLine / HighLine with firmware version V05.01 or higher
Behaviour of the new version?
The Ixt monitoring is not triggered ahead of time
Which products are affected?
8400 StateLine / HighLine with FW < 05.01
What happens?
If C0173 > 0, Ixt and switching frequency-dependent current thresholds are too low for single-phase devices, and as a consequence the inverter reports an overload (Ixt warning) before this is actually the case.
When does the problem occur?
If mains voltages > 400 V, three-phase, or 230 V, single-phase, (C0173 > 0) are selected, the derating factor is also considered in the Ixt function for 230 V devices.
Possible diagnostics?
Ixt monitoring is triggered ahead of time
Short-term measures / recommendations?
Set C0173 to 0 for single-phase devices (default value)
Evaluation:
The error is likely to occur during commissioning and can be avoided if the recommendations are followed.
