29-02 Pipe Fill Speed [Hz]
Range: Function:
Motor
Speed Low
Limit*
[Speed Low Limit - Speed High Lim-
it]
Set the filling speed for filling horizontal pipe systems. The speed can be selected in Hz or RPM
depending on the choices made in par. 4-11 / par. 4-13 (RPM) or in par. 4-12 / par. 4-14 (Hz).
29-03 Pipe Fill Time
Range: Function:
0 s* [0–3600 s] Set the specified time for pipe filling of horizontal pipe systems.
29-04 Pipe Fill Rate
Range: Function:
0.001 units/
s*
[0.001–999999.999 units/s] Specifies the filling rate in units/second using the PI controller. Filling rate units are feedback units/
second. This function is used for filling vertical pipe systems but will be active when the filling time
has expired, no matter what, until the pipe fill setpoint set in par. 29-05 is reached.
29-05 Filled Setpoint
Range: Function:
0 s* [0–999999,999 s] Specifies the filled setpoint at which the pipe fill function will be disabled and the PID controller will
take control. This function can be used both for horizontal and vertical pipe systems.
5.3 Parameter Options
5.3.1 Default settings
Changes during operation:
“TRUE” means that the parameter can be changed while the adjustable frequency drive is in operation, and “FALSE” means that the adjustable frequency
drive must be stopped before a change can be made.
4 set-up:
'All set-up': the parameter can be set individually in each of the four set-ups, i. e., one single parameter can have four different data values.
’1 set-up’: data value will be the same in all set-ups.
SR:
Size related
N/A:
No default value available.
Conversion index:
This number refers to a conversion figure used when writing or reading by means of an adjustable frequency drive.
