Corrected from:
Inverter Drives 8400 HighLine and TopLine from firmware version 14.00.00.00
Response of the new version?
With code C2864/1 bit 5, the field/field weakening control can be set so that it works in a cycle of 500 μs instead of a 1 ms cycle. Like this, the response in the field weakening range can be optimised.
Which products are affected?
Inverter Drives 8400 HighLine and TopLine with a firmware version lower than 14.00.00.00
What happens?
The field/field weakening control does not work correctly, which may result in a deviation between the setpoint and the actual value.
When does the problem occur?
With machines which are actuated with SC-ASM and which are working in the field weakening range.
Short-term measures/recommendations?
None
Evaluation:
If the inverter is working in the field weakening range and if deviations in the setpoint and actual profile occur, which are not tolerable, an update to FW 14.00.00.00 must be carried out, and code C2864 bit 5 must be set to True.
