Remedied from:
8400 StateLine SW V4.00 onwards
8400 HighLine SW V4.00 onwards
Behaviour of the new version?
The above-named software version rectifies this functional restriction.
Which products are affected?
8400 StateLine SW ≤ V3.01
8400 HighLine SW ≤ V2.01
What happens?
The Ixt monitoring function (15 s cycle) is triggered prematurely if a switching frequency of 16 kHz has been set.
When does the problem occur?
The problem occurs if the device's output current reaches the fault limit for Ixt monitoring of the 15 s cycle and the set switching frequency is 16 kHz.
Possible diagnostics?
If Ixt monitoring is triggered, compare the L-C00064/1 display code with the current motor current (L-C00054).
Short-term measures/recommendations?
At a switching frequency of 16 kHz, deactivate the error response of the Ixt monitoring function (L-C00604)
Evaluation:
This behaviour is usually noticed during commissioning and can be rectified in accordance with the recommendations.
