Temperature
P14 Inverter Current
A
This parameter shows the actual current supplied by the
frequency converter.
P15 Inverter Voltage
V
This parameter shows the actual estimated input voltage of
the frequency converter.
P16 Motor Speed
rpmx10
This parameter shows the actual motor rotational speed.
P17 Software version
This parameter shows the Control Board software version.
6.5.2 Settings Parameters
No. Parameter
Description
P20 Password
entering
[0÷999]
The user can enter here the system password, which gives access to all system
parameters: this value is compared with the one stored in P22.
When a correct password is entered, the system remains unlocked for 10 minutes.
P21 Jog Mode
[MIN÷MAX
*
]
It deactivates the internal controller of the unit and forces the actual Control Mode (ACT):
the motor starts and the value of P21 becomes the temporary ACT setpoint. It can be
changed by just entering a new value on P21 without confirming it; otherwise, it causes
immediate exit from temporary control.
P22 System
password
[1÷999]
This is the system password, and must be the same as the password entered in P20.
Default: 66.
P23 Lock Function
[OFF, ON]
By using this function, the user can lock or unlock parameter setting in the main menu.
When ON, enter the P20 password to change the parameters.
Default: ON.

Description
P25 Control
mode [0-2]
This parameter sets the Control Mode: ACT=0, CPP=1 e PPP=2
ACT: Actuator mode.
ACT
ACT
A single pump maintains a fixed speed at any flow rate. ACT will always try
to minimize the difference between the speed setpoint and the actual
rotational speed of the motor.
CCP: PI constant pressure.
CPP
CPP
The pump maintains a constant pressure delta (difference between
discharge and suction pressure) irrespective of the flow rate.
No absolute pressure sensor is required. The control algorithm will work in
sensorless mode. In any case, as an alternative it will be possible to use an
external pressure sensor (for the connections see par. 4.3.3, configured
from P40): CPP will always try to reduce to the minimum the error between
the pressure setpoint and the pressure feedback signal.
PPP: PI proportional pressure.
PPP
PPP
This is a control mode during which the pump keeps a proportional
pressure delta (difference between discharge and suction pressure)
irrespective of the flow needed. The pressure increases with the increase of
the flow. The control algorithm will work in sensorless mode. In any case,
as an alternative it will be possible to use an external pressure sensor (for
the connections see par. 4.3.3, configured from P40): PPP will always try to
reduce to the minimum the error between the pressure setpoint and the
