Alternance
ON/OFF
ON
Enabling of the alternation between units in COMBO
and D.O.L.
The order of priority of operation is alternated based on
the previous start-up of each pump in order to obtain an
almost uniform wear of the pumps.

Altern. period
t = XX [h]
0
Maximum difference in operating hours between multi-
ple devices in the group.
0 means 5 minutes.

COMBO synchrony
ON/OFF
OFF
Through this parameter it is possible to activate the syn-
chronous operation of the pumps in COMBO. Read the
dedicated chapter.
However, it is necessary to lower the parameter
Freq.min.control accordingly.

Start delay AUX
t = XX [s]
00
Time delay with which the pumps in a group start up af-
ter the variable speed pump has reached the maximum
motor frequency and the measured value has fallen be-
low the difference Set value - Delta control.

PI control
Direct/Reverse
Direct
PI control mode:
• Direct : as the pump speed increases, the measured
value increases.
• Reverse : as the pump speed increases, the meas-
ured value decreases.

Dry run cosphi
cosphi = X.XX
Cosphi value that is measured when the pump is run-
ning dry. Below this value the device stops the pump
and produces a water shortage alarm.
If the motor is of synchronous type with permanent
magnets, this parameter represents the percentage with
respect to the rated current set below which the device
stops the motor and generates the lack of water alarm.

Restarts delay
t = XX [min]

Time base that establishes the delay of attempts to re-
start the pump following a water shortage alarm. With
each attempt the delay time is doubled. The maximum
number of attempts is 5.

Description
Motor type
XXXXXXXX
Threep
hase
asyn.
Type of motor connected and control used:
• Threephase asyn. : Control for three-phase asynchronous motors.
• Synchronous PM : Control for permanent magnet synchronous motors.
Rated motor Volt
V = XXX [V]
Nominal voltage of the motor according to its plate data.
The average voltage drop across the inverter is between 20 and 30 V RMS depending on
the load conditions.
Voltage boost
V = XX.X [%]
Increased voltage at motor start-up to increase starting torque.
Contact the motor manufacturer for more information.
