Operating ranges
The converter can only be operated with reduced output current at low output frequencies.
The connection is shown in the following diagram.
The diagram clearly demarcates continuous duty ranges from short-time duty ranges.
The operating ranges are used to ensure that the converter operates reliably at all times,
including in particular in relation to lifetime expectancy.
Figure 6-1
Operating ranges
Explanation of the operating ranges:
●
Continuous duty (green range in the diagram)
Continuous duty is permitted in this range without restriction.
●
Short-time operation (yellow range in the diagram)
In this range, operation for a total of 2
% of the total operating duration is permissible
without noticeably reducing the converter service life. There is no overload reaction
through the thermal monitoring model.
●
Sporadic short-time operation (red range in the diagram)
In this range, operation is only permissible for very brief and infrequent operating states
of less than 0.1
%
of the total operating duration, without noticeably reducing the
converter service life. There is no overload reaction through the thermal monitoring model
if the times stated in the diagram are complied with.
