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, parameter group 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).
NOTE
If Sleep Mode is to be based on No Flow Detection/
Minimum Speed, remember to choose Sleep Mode [1] in
22-23 No-Flow Function.
If 25-26 Destage At No-Flow is set for Enabled, activating
Sleep Mode will send a command to the cascade controller
