403 Sleep mode timer
(SLEEP MODE TIMER)
Value:
0 - 300 sec. (301 sec. = OFF)
✭
OFF
Function:
This parameter enables the frequency converter to
stop the motor if the load on the motor is minimal.
The timer in parameter 403
Sleep mode timer
starts
when the output frequency drops below the frequency
set in parameter 404
Sleep frequency
.
When the time set in the timer has expired, the
frequency converter will turn off the motor.
The frequency converter will restart the motor, when
the theoretical output frequency exceeds the frequency
in parameter 407
Wake up frequency.
Description of choice:
Select OFF if this function is not wanted. Set
the threshold value that is to activate Sleep
mode after the output frequency has fallen below
parameter 404
Sleep frequency
.
404 Sleep frequency
(SLEEP FREQUENCY)
Value:
000,0 - par. 407
Wake up frequency
✭
0,0 Hz
Function:
When the output frequency falls below the preset value,
the timer will start the time count set in parameter 403
Sleep mode
. The present output frequency will follow
the theoretical output frequency until f
MIN
is reached.
Description of choice:
Set the required frequency.
405 Reset function
(RESET MODE)
Value:
✭
Manual reset (MANUAL RESET)
[0]
Automatic reset x 1 (AUTOMATIC X 1)
[1]
Automatic reset x 2 (AUTOMATIC X 2)
[2]
Automatic reset x 3 (AUTOMATIC X 3)
[3]
Automatic reset x 4 (AUTOMATIC X 4)
[4]
Automatic reset x 5 (AUTOMATIC X 5)
[5]
Automatic reset x 6 (AUTOMATIC X 6)
[6]
Automatic reset x 7 (AUTOMATIC X 7)
[7]
Automatic reset x 8 (AUTOMATIC X 8)
[8]
Automatic reset x 9 (AUTOMATIC X 9)
[9]
Automatic reset x 10 (AUTOMATIC X 10)
[10]
Reset at power-up (RESET AT POWER UP)
[11]
Function:
This parameter makes it possible to select the
reset function desired after tripping.
After reset, the FC motor can be restarted after 1.5 sec.
Description of choice:
If
Manual reset
[0] is selected, reset must be
effected via the digital inputs.
If the FC motor is to carry out an automatic
reset (max. 1-10 times within 10 minutes) after
tripping, select data value [1]-[10].
Warning: The motor may start without
warning up to 10 x 5 sec. after trip.
406 Boost setpoint
(BOOST SETPOINT)
Value:
1 - 200 %
✭
100 % of setpoint
Function:
This function can only be used if
Closed loop
has
been selected in parameter 100.
In systems with constant pressure regulation, it is
advantageous to increase the pressure in the system
before the frequency converter stops the motor.
This extends the time during which the frequency
converter stops the motor and helps to avoid frequent
starting and stopping of the motor, e.g. in the case
of leaks in the water supply system.
Description of choice:
Set the required
Boost setpoint
as a percentage
of the resulting reference under normal operation.
100% corresponds to the reference without
boost (supplement).
407 Wake up frequency
(WAKEUP FREQUENCY)
Value:
Par 404
Sleep frequency
- par. 202 f
MAX
✭
50 Hz
Function:
When the theoretical output frequency exceeds the
preset value, the frequency converter restarts the motor.
