We recommend that you always use the Soft fill function when you use the Multi-pump
function.
P3.13.8.1 ENABLE SOFT FILL (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.
The drive accelerates to this frequency before it starts to control. After this, the drive goes to
normal PID control mode.
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.
The drive operates at the soft fill frequency until the feedback value is equal with the soft fill
level. If the feedback value does not become equal with the soft fill level during the timeout,
an alarm or fault shows. You can make a selection of the response with parameter P3.13.8.5
(PID Soft Fill Timeout Response).
NOTE!
If you set the value to be 0, no fault shows.
