29-02 Pipe Fill Speed [Hz]Range: Function:MotorSpeed LowLimit*[Speed Low Limit - Speed High Lim-it]Set the filling speed for filling horizontal pipe systems. The speed can be selected in Hz or RPMdepending 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 TimeRange: Function:0 s* [0–3600 s] Set the specified time for pipe filling of horizontal pipe systems.29-04 Pipe Fill RateRange: 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 timehas expired, no matter what, until the pipe fill setpoint set in par. 29-05 is reached.29-05 Filled SetpointRange: Function:0 s* [0–999999,999 s] Specifies the filled setpoint at which the pipe fill function will be disabled and the PID controller willtake control. This function can be used both for horizontal and vertical pipe systems.5.3 Parameter Options5.3.1 Default settingsChanges during operation:“TRUE” means that the parameter can be changed while the adjustable frequency drive is in operation, and “FALSE” means that the adjustable frequencydrive 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 relatedN/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.Conv. index 100 67 6 5 4 3 2 1 0 -1 -2 -3 -4 -5 -6Conv. factor 1 1/60 1000000 100000 10000 1000 100 10 1 0.1 0.01 0.001 0.0001 0.00001 0.000001Data type Description Type2 Integer 8 Int83 Integer 16 Int164 Integer 32 Int325 Unsigned 8 Uint86 Unsigned 16 Uint167 Unsigned 32 Uint329 Visible String VisStr33 Normalized value 2 bytes N235 Bit sequence of 16 Boolean variables V254 Time difference w/o date TimDVLT AQUA High Power Instruction Manual5 How to program the adjustable frequencydriveMG.20.P3.22 - VLT® is a registered Danfoss trademark 5-495
