3.11.3 Overload monitoring of the power unit
Overload monitoring protects the power unit against thermal monitoring. Thereby thermal
load is emulated and monitored by a model. There are two methods for this:
m
Temperature model (enabled, if complete thermal data set is available in the de-
vice's characteristics (
bit 3 = 1) and if the temperature model is selected
bit 1 = 1).
m
Ixt model (is operated, if the temperature model is not enabled).
Parameter Status PU temperature model
bit 0 displays, which method is en-
abled.
3.11.3.1 Ixt model
The thermal load of the complete device is emulated on the basis of total current and peak
current time.
