/
Cavitation speed

+100%
Setting of the cavitation speed above which the second detection
condition to activate the protection is met. This parameter operates
together with parameters G25.6.4 and G25.6.6. See note in the
previous footer.
YES

10s
Setting of the delay time to activate the cavitation protection. The
drive will wait for this time before activating the protection and then
will stop. This parameter operates together with parameters G25.6.4
and G25.6.5. See note in the previous footer.

Trip
delay time

0 – 999s
10.0s
During the delay time set here, the pressure remains below the
minimum pressure level set in G25.6.9 generating a drive trip
because of low pressure fault 'F65 LOW PRESSURE'.
Note
: The minimum pressure protection is deactivated during pipe
filling process. If a pipe is broken during the pipe filling process or
when the drive is stopped, then the pipe filling process does not
finish by reached pressure, but by time. Once finished the stage of
pipe filling, the breakage detection will be activated and will trip after
elapsing the set time.
Additionally, it is necessary to consider, if enabled fixed pumps
exist, these ones must be connected for the minimum pressure
conditions are evaluated, otherwise, the drive executes the normal
connection process of pumps before tripping by minimum pressure.
YES
11 Lop Msp=+0.0%
LO PRESS MIN SPED
G25.6.11 /
Minimum speed
for minimum
pressure fault
+0.0% to
+250%
+0.0%
It sets a minimum speed for the minimum pressure fault ‘F65 LOW
PRESSURE’ (Possible broken pipe). Although Hardware or
Software conditions exist (favourable comparison) to trip by
minimum pressure fault, the trip is not produced while the present
motor speed is not lower than the speed set in this parameter, if any
of the enabled fixed pumps is not started either. In short, it is an
additional safety measurement to guarantee the broken pipe
detection with a higher reliability. It is set in % of motor rated speed.

PAUSE
It allows selecting the drive response from an over-pressure
situation.
OPT
FUNCTION
PAUSE
It will generate the stopping of the drive, and next,
the fixed pumps. ‘HI PRESSURE PAUS’ will be
visualized. Once the high pressure condition
disappears, if the delay time after pause has
elapsed, the drive will start.
FAULT
It will cause a fault and next, the fixed pumps will
be stopped. In this case, ‘F66 HI PRESSURE’ will
be visualized.
YES

Engineering
units
100Bar
It allows setting the high pressure level above which the drive
recognises a level of high pressure by comparing with data received
through analogue input (reading of PID feedback sensor). Once
exceeded the detection threshold and elapsed the time set in
G25.6.14, the drive will stop by PAUSE or will trip by FAULT,
according to the setting realized in G25.6.12.

Setting of the trip time by high pressure. Once exceeded the

drive will stop by PAUSE or will trip by FAULT according to the
setting realized in G25.6.12.
