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 ( must be 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 configuration of the
digital inputs, par. 5-1* selecting [66] Sleep Mode). Sleep mode
is activated only when no wake-up conditions are present.
To make it possible to use e.g. an electro-mechanical flow
switch to detect a no flow condition and activate Sleep Mode,
the action takes place at raising edge of the external signal
applied (otherwise the frequency converter would never come
out of Sleep Mode again as the signal would be steady
connected).
