P0292 Inverter temperature warning Min: 0
CStat: CUT Datatype: U16 Unit: °C Def: 5
P-Group: INVERTER Active: first confirm QuickComm.: No Max: 25
Defines the temperature difference (in ºC) between the Overtemperature trip threshold and the warning
threshold of the inverter. The trip threshold is stored internally by the inverter and cannot be changed by the
user.

warn
If the actual inverter temperature (r0037) exceeds the corresponding threshold, a warning A0504, if the
temperature still increases then a fault F0004 will be displayed.
P0294 Inverter I2t overload warning Min: 10.0
CStat: CUT Datatype: Float Unit: % Def: 95.0
P-Group: INVERTER Active: first confirm QuickComm.: No Max: 100.0
Defines the [%] value at which alarm A0505 (inverter I2t) is generated.
Inverter I2t calculation is used to determine a maximum tolerable period for inverter overload. The I2t
calculation value is deemed = 100 % when this maximum tolerable period is reached.
Dependency:
That the output current of the inverter has been reduced and that the value of I2t does not exceed 100%.
Note:
P0294 = 100 % corresponds to stationary nominal load.
P0295 Inverter fan off delay time Min: 0
CStat: CUT Datatype: U16 Unit: s Def: 0
P-Group: TERMINAL Active: first confirm QuickComm.: No Max: 3600
Defines inverter fan switch off delay time in seconds after drive has stopped.
Note:
Setting to 0, inverter fan will switch off when the drive stops, that is no delay.
