7.3 Overload Monitoring of Power Unit
This monitoring protects the power unit from thermic overload. The temperature of the power unit is im-
itated and monitored by a Ixt model.
Parameter overview
Parameter description
P139
PU Ixt value
This parameter displays the actual Ixt value of the overload monitoring. At a value equal
100 % follows a current limitation to nominal current (P114). Drops the Ixt value below 95%
the current value is set to PU I limit (P116).
