Parameter 30-27 Light Load Speed [%]
Table 713: Parameter 30-27 Light Load Speed [%]
30-27 Light Load Speed [%]
Default Value: 0%
Conversion Index: 0
Use this parameter when the light-load detection is active to define the speed during current measurement. Enter the reference
speed during the light-load detection. The value is a percentage of nominal motor speed in parameter 1-25 Motor Nominal Speed.
For standard asynchronous motors, the synchronous speed is used instead of parameter 1-25 Motor Nominal Speed due to slip.
Parameter 30-28 Evacuation Speed [%]
Table 714: Parameter 30-28 Evacuation Speed [%]
30-28 Evacuation Speed [%]
Default Value: 0%
Conversion Index: 0
Speed for evacuation after detection of light-load direction.
Parameter 30-29 Ramp Time
Table 715: Parameter 30-29 Ramp Time
30-29 Ramp Time
Default Value: Size related
Conversion Index: -2
Ramp times during evacuation and measurement sequences.

4.20.3 30-5* Unit Configuration

Parameters in this group allow to configure the operation of internal units that communicate with the drive. The settings affect the
behavior of hardware components inside the drive.
Parameter 30-50 Heat Sink Fan Mode
Table 716: Parameter 30-50 Heat Sink Fan Mode
30-50 Heat Sink Fan Mode
Default Value: Size related
Conversion Index: -
Select how the heat sink fan responds to operating conditions. Use parameter 14-52 Fan Control to control the minimum fan speed.
