11.15.8.2 (ID 1055) Soft Fill Frequency
Location in the menu: P3.13.8.2
Use this parameter to set the frequency reference of the drive when the Soft Fill function is used.
11.15.8.3 (ID 1095) Soft Fill Level
Location in the menu: P3.13.8.3
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'.
11.15.8.4 (ID 1096) Soft Fill Timeout
Location in the menu: P3.13.8.4.
Use this parameter to set the timeout time for the Soft Fill function. When the soft fill function is set to 'Enabled, Level', this parame-
ter 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 the option Enabled (Timeout) is selected 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 soft fill frequency (P3.13.8.2 Soft Fill Frequency) before the PID controller starts the
regulation.
11.15.8.5 (ID 748) Soft Fill Fault
Location in the menu: P3.13.8.5.
Use this parameter to select the response of the drive to a 'PID Soft Fill' fault. If the PIDFeedback value does not reach the set level in
the time limit, a soft fill fault occurs.

11.15.9 Input Pressure Supervision
Use the Input pressure supervision to make sure that there is enough water in the inlet of the pump. When there is enough water,
the pump does not suck air and there is no suction cavitation. To use the function, install a pressure sensor on the pump inlet.
If the input pressure of the pump goes below the set alarm limit, an alarm shows. The setpoint value of the PID controller decreases
and causes the output pressure of the pump to decrease. If the pressure goes below the fault limit, the pump is stops and a fault
shows.

Description
The drive operates at a constant frequency (P3.13.8.2 Soft Fill Frequency) until the PID feedback sig-
nal 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 is shown (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.
