Saves the penultimate error in chronological occurred.
Other characteristics: like P09.
P11
3rd error
Saves the third from the last error in chronological occurred.
Other characteristics: like P09.

P13
Power Module
Temperature
°C
Temperature of the power module.
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

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 paramet ers:
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.
6.5.3 Drive Configuration Parameters

Description
P25
Control mode
[ACT, HCS, MSE,
MSY]
This parameter sets the Control Mode (default value: HCS)
ACT : Actuator mode.
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.
If a 0-10V signal is supplied to terminals 7 and 8, the pump
automatically switches to ACT mode, following the external signal, as
shown in figure 17.
If the external signal is missing, the pump remains in ACT mode, using
the value set as setpoint using the display.
HCS : Hydrovar® Controller mode for Single pump.
The pump maintains a constant pressure at any flow rate: the
Hydrovar® algorithm, based on the set of parameters from P26 to P37
(see Par. 6.5.3), is implemented.
HCS mode must be set in conjunction with the use of an absolute
reading pressure sensor installed in the hydraulic circuit, which
