PPLICATION
PUMP SOFT FILL FUNCTION
The Soft Fill function is used, for example, to avoid pressure pikes, the so-called "water ham-
mers" in pipes when the drive starts to regulate. If not controlled, these pikes might lead to dam-
aged pipes. See more information on page 81.
Figure 23.
The drive runs at the
Soft fill frequency
(M3.12.7.2) until the actual value reaches the
Soft fill
level
(M3.12.7.3). After this the drive starts to regulate. If the
Soft fill level
isn't reached within
the
Soft fill timeout
(M3.12.7.4) an alarm or fault is triggered according to the
Soft fill supervision
response (M3.9.16).
NOTE:
The Soft fill function is disabled if parameter M3.12.1.8
Error inversion
is set to
Inverted
