Level

3

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.

Temperature warning threshold of inverter T_warn

Twarn = Ttrip - P0292

Temperature shutdown threshold of inverter T_trip

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:

CUT

Datatype: Float

Unit: %

Def:

P-Group:

INVERTER

Active: first confirm

QuickComm.: No

Max:

100.0

Defines the [%] value at which alarm A0505 (inverter I2t) is generated.

Level

4

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

Level

3

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.
