bar Units of measurement [bar,%, ft, in, cm, m, K, F, C, gpm, l / min, m3 / h, atm, psi].
Motor type
XXXXXX
Threep-
hase
asyn.
Type of motor connected and control used:
• Singlephase PSC: control for single-phase 2-wire PSC motors.
• Threephase asyn.: control for three-phase asynchronous motors.
• Synchronous PM: control for permanent magnet synchronous motors.
• Scalar: V / f scalar control.
Rated motor Amp.
I = XX.X [A]
Motor rated current according to its data plate increased by 5%. The voltage drop across the inverter
may result in a current absorption greater than the motor rated current indicated on the data plate. It
is necessary to check with the motor manufacturer that this overcurrent can be tolerated.
Rated motor freq
f = XXX [Hz]
50 Rated frequency of the motor according to its data plate.
F.scale sensor
p = XX.X [bar]
16 Full scale of the sensor.
Sensor test
Press ENT
The sensor must be tested before use.
If the sensor is not connected, or is incorrectly connected, pressing the ENTER button would be
followed by the indication SENSOR OFF
Max alarm value
p = XX.X [bar]
10 Value that can be reached in the system beyond which, even in constant frequency operating mode,
the pump is stopped and an alarm signal is emitted. The pump is restarted only after the measured
value has dropped below the maximum alarm value for more than 5 seconds.
Set value
p = XX.X [bar]
3 Value that you want to keep constant.
Motor tuning
ENT to access
If the device is "FOC-ready", motor calibration must be carried out before commissioning.
WARNING
Carefully read the chapter dedicated to the FOC motor control.
Motor test
START/STOP
By using START / STOP it is possible to carry out a running test of the pump at the desired working
frequency.
WARNING
Check that the pump can be started without causing damage to it or to the system.
Rotation sense
---> / <---
---> Running direction of the motor. Should the motor run in the wrong direction, it is possible to reverse
the running direction without having to change the phase sequence in the connection.
COMBO
ON/OFF
OFF Enable the function COMBO for the combined operation of several pumps in parallel. Read the
dedicated chapter.
Address
XX
Device address when in COMBO mode:
• 0: master
• 01 to 07: slave
BTLE connection
ON / OFF
ON Enable BTLE communication
Autorestart
ON/OFF
OFF By selecting ON, when the mains power is restored after a power failure, the device will return to the
same state it was in before the power failure: this means that if the pump was working, it will start
working again
INITIAL SETUP
COMPLETED
This message informs the user that the initial set-up procedure has been successfully completed. The
parameters set during this procedure are saved in the device. These values can be subsequently
modified from the appropriate menus.
9.4. FOC motor control
9.4.1. Introduction
The benefits provided by the FOC (Field Oriented Control) motor control implemented in the "FOC-ready" inverters
over a traditional control are as follows:
• Ideal control of the current at each operating point.
