SINAMICS G120 Control Units CU240S, Edition 05/2007
Description: Displays motor power.
Dependency: Value is displayed in [kW] or [hp] depending on setting for P0100 (operation for Europe / North America).
Description: Displays measured motor temperature.
Description: Displays inverter overload utilization calculated via the I2t model.
The actual I2t value relative to the max. possible I2t value supplies utilization in [%].
If the current exceeds the threshold for P0294 (inverter I2t overload warning), alarm A0505 (inverter I2t) is gener-
ated and the output current of the inverter reduced via P0290 (inverter overload reaction).
If 100 % utilization is exceeded, alarm F0005 (inverter I2t) is tripped.
Example:
Dependency: r0036 > 0:
If the nominal current (see r0207) of the inverter is exceed, utilization will be displayed, otherwise, 0 % utilization is
displayed.
