Function:
Read out of calculated No Flow power
at actual speed. If power drops to the
display value the frequency converter
will consider the condition as a No Flow
situation.
Function:
Make corrections to the calculated power at
22-30 No-Flow Power.
If No Flow is detected, when it should not be
detected, the setting should be decreased.
However, if No Flow is not detected, when it
should be detected, the setting should be
increased to above 100%.
Function:
[ 0 - par. To be used if 0-02 Motor Speed Unit
has been set for RPM (parameter not
visible if Hz selected).
Set used speed for the 50% level.
This function is used for storing values
needed to tune No Flow Detection.
Function:
[ 0.0 - par. To be used if 0-02 Motor Speed Unit
has been set for Hz (parameter not
visible if RPM selected).
Set used speed for the 50% level.
The function is used for storing values
needed to tune No Flow Detection.
Function:
[ 0.00 - To be used if 0-03 Regional Settings has
been set for International (parameter
not visible if North America selected).
Set power consumption at 50% speed
level.
This function is used for storing values
needed to tune No Flow Detection.
Function:
[ 0.00 - To be used if 0-03 Regional Settings has
been set for North America (parameter
not visible if International selected).
Set power consumption at 50% speed
level.
This function is used for storing values
needed to tune No Flow Detection.

3.20.3 22-4* Sleep Mode
If the load on the system allows for stop of the motor and
the load is monitored, the motor can be stopped by
activating the Sleep Mode function. This is not a normal
Stop command, but ramps the motor down to 0 RPM and
stops energizing the motor. When in Sleep Mode certain
conditions are monitored to find out when load has been
applied to the system again.
Sleep Mode can be activated either from the No Flow
Detection/Minimum Speed Detection (
programmed via parameters for No-Flow Detection, see
the signal flow-diagram in parameter group 22-2*, No-Flow
Detection) or via an external signal applied to one of the
digital inputs (must be programmed via the parameters for
