5.
The speed setpoint is greater than
parameter 22-43 Wake-Up Speed [Hz]
. The sleep
condition has lasted longer than the time set in
parameter 22-41 Minimum Sleep Time
. The wake-
up condition lasts longer than the time set in
parameter 22-49 Wake-Up Delay Time
. The
frequency converter is now out of sleep mode.
6.
Go back to speed open-loop control (ramp motor
speed up to the speed setpoint).
The sequence when running sleep mode in closed loop:
1.
The frequency converter goes into boost status if
the following conditions are met.
•
If
parameter 22-02 Sleepmode CL Control
is set to
[0] Normal
:
-
The motor speed is less than
the value in
parameter 22-47 Sleep Speed
[Hz]
-
The feedback is above the
reference.
-
The motor runs longer than
the time in
parameter 22-40 Minimum Run
Time
.
-
The sleep condition lasts
longer than the time in
parameter 22-48 Sleep Delay
Time
.
•
If
parameter 22-02 Sleepmode CL Control
is set to
[1] Simplified
:
-
The motor speed is less than
the value in
parameter 22-47 Sleep Speed
[Hz]
-
The motor runs longer than
the time in
parameter 22-40 Minimum Run
Time
.
-
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
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
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.
22-40 Minimum Run Time
Range:
Function:
10 s
*
[0 - 600 s] Set the wanted minimum running time for
the motor after a start command (digital
input or bus) before entering sleep mode.
22-41 Minimum Sleep Time
Range:
Function:
10 s
*
[0 - 600 s] Set the minimum time for staying in sleep
mode. This time overrides any wake-up
conditions.
22-43 Wake-Up Speed [Hz]
Range:
Function:
10
*
[ 0 -
400.0 ]
Only to be used if
parameter 1-00 Configuration
Mode
, is set for open loop and an external
controller applies speed reference. Set the
reference speed at which the sleep mode
should be deactivated.
22-44 Wake-Up Ref./FB Diff
Range:
Function:
10 %
*
[0 -
100 %]
Only to be used if
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
set
) before canceling
the sleep mode.
