AWAKENING LEVEL
G25.3.1
/ Wake
up level of the
drive
0.0 – 100%
0.0%
It allows setting the wake up level of the drive set as percentage of
the PID setpoint.
That means, if the PID setpoint is 5Bars and the set value in this
parameter is 10%, then 10% of 5 is 0.5 and because it is a
differential value, then we are placing the wake up level below
4,5Bars (5Bars – 0.5 = 4,5Bars).
YES
2 FP SpON=+90.0%

G25.3.2
/ Start
speed for the
fixed pumps
OFF=0 to
+250%
+90.0%
It set the drive speed for above of which the fixed pumps will start.
This is an optional condition that can be disabled. For that set here
a value of 0%, in that way any speed for above of this it is able to
start the pumps, that means, the speed of drive it is not considered
to start the fixed pumps. This is equivalent to an obligation instead
of a condition. It is set as % of the motor speed.

FIX PMP STAR ERR
G25.3.3

Minimum PID
error to start the
fixed pumps
OFF=0 to
+200%
+10.0%
To set the PID error above of which the fixed pumps will start. It is
also optional conditions that can be considered or not depending on
the setting.
This parameter, allows user the possibility of having into
consideration the PID error (%) when the fixed pumps must be
started. If the error is set to 0.0%, any value could start the fixed
pumps.
YES
4 FP T1 ON=10s
FIX PMP1 STR DLY
G25.3.4
/ Delay
time to start fixed
pump 1 (Relay 1)
OFF=0 to
6000
10s
Set the delay time to start the fixed pump linked to the relay 1.
Note:
If time is too short, overpressure can be generated in the
system. If time is too long, under-pressure can be generated.
YES
5 FP T2 ON=10s
FIX PMP2 STR DLY
G25.3.5
/ Delay
time to start fixed
pump 2 (Relay 2)
OFF=0 to
6000
10s
Set the delay time to start the fixed pump linked to the relay 2.
Note:
If time is too short, overpressure can be generated in the
system. If time is too long, under-pressure can be generated.
YES
6 FP T3 ON=10s
FIX PMP3 STR DLY
G25.3.6
/ Delay
time to start fixed
pump 3 (Relay 3)
OFF=0 to
6000
10s
Set the delay time to start the fixed pump linked to the relay 3.
Note:
If time is too short, overpressure can be generated in the
system. If time is too long, under-pressure can be generated.
YES
7 FP T4 ON=10s
FIX PMP4 STR DLY
G25.3.7
/ Delay
time to start fixed
pump 4 (AO1)
OFF=0 to
6000
10s
Set the delay time to start the fixed pump linked to the Analogue
Output 1.
Note:
If time is too short, overpressure can be generated in the
system. If time is too long, under-pressure can be generated.
YES
8 FP T5 ON=10s
FIX PMP5 STR DLY
G25.3.8
/ Delay
time to start fixed
pump 5 (AO2)
OFF=0 to
6000
10s
Set the delay time to start the fixed pump linked to the Analogue
Output 2.
Note:
If time is too short, overpressure can be generated in the
system. If time is too long, under-pressure can be generated.
YES
Note
: General considerations for starting conditions. It must be take into account that, during the setpoint
ramp, neither the conditions for the activation of the fixed pumps nor the conditions for sleep mode will be
considered. Only when the drive is in regulation process (see G25.7.4 for additional information), those
conditions will be evaluated.
During the bypass process (fixed pumps connection) these conditions will be omitted too.
