Parameters
List of Parameters
r0032 CO: Act. filtered power / Act fil. power
Access level: 2
Unit: -
Description: Displays motor power.
Dependency: Value is displayed in [kW] or [hp] depending on setting for P0100 (operation for Europe / North America).
r0035[0...2] CO: Act. motor temperature / Act. mot.temp.
Access level: 2
Unit: [°C]
Description: Displays measured motor temperature.
r0036 CO: Inverter overload utilization / Invert ovl util
Access level: 4
Unit: [%]
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:
Normalized output current
p0294 (95 %)
Dependency: r0036 > 0:
If the nominal current (see r0207) of the inverter is exceed, utilization will be displayed, otherwise, 0 % utilization is
displayed.
