Parameters
c. The motor runs longer than
the time in
parameter 22-40 Minimum Run
Time.
d. The sleep condition lasts
longer than the time in
parameter 22-48 Sleep Delay
Time.
1b If parameter 22-02 Sleepmode CL Control
Mode is set to [1] Simplified:
a. The motor speed is less than
the value in
parameter 22-47 Sleep Speed
[Hz].
b. The motor runs longer than
the time in
parameter 22-40 Minimum Run
Time.
c. The sleep condition lasts
longer than the time in
parameter 22-48 Sleep Delay
Time.
If parameter 22-45 Setpoint Boost is not
set, the frequency converter goes into
sleep mode.
2. After the time in parameter 22-46 Maximum Boost
Time has passed, the frequency converter ramps
down the motor speed to the speed in
parameter 1-82 Min Speed for Function at Stop [Hz].
3. The frequency converter activates
parameter 1-80 Function at Stop. The frequency
converter is now in sleep mode.
4. The frequency converter is out of sleep mode:
4a When the error between the reference
and the feedback is greater than
parameter 22-44 Wake-Up Ref./FB Diff,
and
4b the sleep time is longer than the time in
parameter 22-41 Minimum Sleep Time,
and
4c the wake-up condition lasts longer than
the time set in parameter 22-48 Sleep
Delay Time.
5. The frequency converter goes back to closed-loop
control.

NOTICE
Sleep mode is not active when local reference is active
(set speed manually using the navigation keys on the
LCP).
Sleep mode does not work in local mode. Perform an
auto set-up in open loop before setting input/output in
closed loop.

Function:
[0 - 600 s] Set the wanted minimum running time for
the motor after a start command (digital
input or bus) before entering sleep mode.
Function:
[0 - 600 s] Set the minimum time for staying in sleep
mode. This time overrides any wake-up
conditions.
Function:
Only to be used if parameter 1-00 Configuration
Mode is set for [0] Open loop, and an external
controller applies speed reference. Set the
reference speed at which the sleep mode
should be deactivated.
Function:
[0 - Only to be used if parameter 1-00 Configuration
Mode is set for closed loop and the integrated
PI controller is used for controlling the pressure.
Set the pressure drop allowed in percentage of
setpoint for the pressure (P
the sleep mode.
Function:
Only to be used if parameter 1-00 Configuration
Mode is set for closed loop and the integrated PI
controller is used. In systems with for example
constant pressure control, it is advantageous to
increase the system pressure before the motor is
stopped. This increase extends the time the motor
is stopped and helps to avoid frequent start/stop.
Set the required overpressure/overtemperature in
percentage of setpoint for the pressure (P
temperature before entering the sleep mode.
If setting for 5%, the boost pressure is P
The negative values can be used for cooling tower
control where a negative change is needed.
