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.

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.

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

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.
