We recommend that you always use the Soft fill function when you use the Multi-pump
function.
P3.13.8.1 SOFT FILL FUNCTION (ID 1094)
Use this parameter to enable the Soft Fill function. You can use the function to fill an empty
pipe slowly and prevent strong currents of fluid that could break the pipe.

P3.13.8.2 SOFT FILL FREQUENCY (ID 1055)
Use this parameter to set the frequency reference of the drive when the Soft Fill function is
used.
P3.13.8.3 SOFT FILL LEVEL (ID 1095)
Use this parameter to set the level below which the soft fill control is enabled when starting
the drive.
The drive operates at the PID start frequency until the feedback reaches the set value. Then
the PID controller starts to control the drive.
This parameter is applied if the soft fill function is set to 'Enabled (Level)'.
P3.13.8.4 SOFT FILL TIMEOUT (ID 1096)
Use this parameter to set the timeout time for the Soft Fill function. When the soft fill
function is set to Enabled (Level), this parameter gives the timeout for the soft fill level, after
which the soft fill fault occurs. When the soft fill function is set to 'Enabled, Timeout', the
drive operates at the soft fill frequency until the time set by this parameter expires.
If you selected the option Enabled (Timeout) in parameter P3.13.8.1 Soft Fill Function,
parameter Soft Fill Timeout gives the quantity of time that the drive operates at the constant

Selection name
The drive operates at a constant frequency (P3.13.8.2 Soft
Fill Frequency) until the PID feedback signal goes to the soft
fill level (P3.13.8.3 Soft Fill Level). The PID controller starts
the regulation.
In addition, if the PID feedback signal does not go to the soft
fill level in the soft fill timeout (P3.13.8.4 Soft Fill Timeout), a
soft fill fault shows (P3.13.8.4 Soft Fill Timeout is set to
greater than 0).
The soft fill mode is used in vertical installations.
The drive operates at a constant frequency (P3.13.8.2 Soft
Fill Frequency) until the soft fill time (P3.13.8.4 Soft Fill
Timeout) goes. After the soft fill time, the PID controller
starts the regulation.
In this mode, the soft fill fault is not available.
The soft fill mode is used in horizontal installations.
