Parameter 30-27 Light Load Speed [%]
Table 713: Parameter 30-27 Light Load Speed [%]
30-27 Light Load Speed [%]
Default Value: 0%
Parameter Type: Range, 0 - 100%
Setup: All set-ups
Conversion Index: 0
Data Type: Uint16
Change during operation: True
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%
Parameter Type: Range, 0 - 100%
Setup: All set-ups
Conversion Index: 0
Data Type: Uint16
Change during operation: True
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
Parameter Type: Range, 0.01 - 3600 s
Setup: All set-ups
Conversion Index: -2
Data Type: Uint32
Change during operation: True
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

30-50 Heat Sink Fan Mode
Default Value: Size related
Parameter Type: Option
Setup: 2 set-ups
Conversion Index: -
Data Type: Uint8
Change during operation: True
Select how the heat sink fan responds to operating conditions. Use
parameter 14-52 Fan Control
to control the minimum fan speed.
