Programming Guide | VLT® HVAC Drive FC 102
Data type: Int32
Set the nominal air volume flow at nominal maximum Hz defined in parameter 4-14 Motor Speed High Limit [Hz] to define the actual
airflow for the filer air volume monitoring.
31-54 Min Limit Monitoring
Default value: 10%
Setup:
All setups
Data type: Uint8
Set the % of maximum speed or air volume where the curve correction changes to a fix minimum value as a fix level.
31-5* SFP Readouts
6.28.6
The SFP function covers the Specific Fan Power according to the EN 16798 definition to calculate the fan power required to move 1 m
air.
Besides calculating the actual power consumption, this function also monitors the actual power consumption and issues a warning if the
consumption is too high.
31-59 Current Specific Fan Power
Default value: 0 Wh
Setup: All setups
Data type:
Uint32
This is the actual SPF in Wh for moving 1m
31-6* SFP Monitoring
6.28.7
31-60 Nominal SFP Trigger
Default value: [0] Off
Setup: All setups
Data type: Uint8
When activating the capture function in parameter 31-61 Captured Air Flow, the actual air flow and speed of the drive are registered and
create the operational baseline for monitoring the additional energy usage.
At the same time, the nominal differential pressure on the configured sensors are stored. These values are used for comparison when the
actual energy usage increases.
