Dual voltage induction motors typically include
six connection terminals. The terminals can be
connected together with links in one of two
ways to suit one of the two rated voltages.
The two ways of connecting the links are
shown below. These are known as “Star” (the
higher voltage) or “Delta” (the lower voltage).

The selection of Star or Delta is not optional
and must match the supply voltage.
Dual voltage motor nameplates include
symbols to represent voltage and full load
current in each configuration.
Delta is represented by a triangle and star by a

The Inverter contains a number of settings
which can be changed to tailor it for use in a
wide range of applications. These settings are
known as parameters.
Parameters are typically referred to by code or
number (eg. P0305 = Rated Motor Current)
with a description available in the manual.
The parameters contain critical information
essential to the correct operation of the
Inverter. Therefore, they should at least be
checked by the user before the Inverter is
operated for the first time.
The parameters listed in section 5 are intended
to provide a starting point to allow for basic
operation of the V20 Inverter.
5. Parameters to set before use
See section 6 to learn how to set a parameter value.
Set the following parameters to allow the V20
to control a motor with Run, Stop and Speed
Control from the integrated keypad.
If any of the parameters have been changed
previously, follow the procedure in section 12
to reset the Inverter to Factory Defaults.

6.1 Press the M key to access parameters.
With the motor stopped and from the status menu (see
illustration on the left), press the M key to access the
parameter menu.
Note: To access the status menu from another menu
press and hold the M key for 2 seconds.
6.2 Select the required parameter.
Use the up and down arrows to locate the parameter you
wish to change - in this case, P0305 motor rated current.
Press the OK key to select it.
Press the OK key again to select index in000 if prompted.
Note: If you are unable to locate the required parameter it
may be hidden. Change P0003 to 2 to enable extended
parameter access.
6.4 Change the parameter value.
Use the up and down arrow keys to change the value as
required. Press the OK to save the changes.
Press and hold the M key for 2 seconds to return to the
status menu.
Note: Depending on the value, pressing and holding
either the up or down key will change the value in larger

6.3 Select the Index (if prompted).
Some parameters contain multiple values which are
“indexed” as part of a set. This allows the V20 to be
configured for use in more than one application as a set
can be selected.
If only one application is required, simply press the OK
key to accept the default index of in000 as shown in the
illustration opposite.

7.3 Changing speed and direction.
The up and down keys increase or decrease the speed.
Pressing the key will change the speed in small increments,
holding the key will change the speed in larger increments.
Press the up and down keys together to change direction.
The arrows icon (shown in the illustration opposite)
indicates when the motor is running in reverse. Note that
reverse direction is not enabled by default. Change P1032
to 0 to enable it.
7.1 Locate frequency in the status menu.
Press the OK button repeatedly to cycle through Output
Voltage (V), Output Current (A) and DC Bus Voltage (V)
until you reach Output frequency (Hz). Hz will be
displayed at the bottom of the screen as shown opposite.
Note: To reach the status menu from another menu,
press and hold the M button for 2 seconds.
7.2 Press the green I button to start the motor.
The green button will start the motor. Ensure it is safe to
do so before proceeding. When the motor is running, a
circular icon will be displayed as shown opposite.
Note: The time taken (in seconds) to reach maximum
speed is determined by parameter P1120. The time taken
to reach less than maximum speed will be proportional to
this.

7.4 Press the red button (labelled O) to stop the motor.
The red button will stop the motor. The circular run icon is no
longer displayed.
Note: The time taken (in seconds) to stop the motor from
maximum speed is determined by parameter P1121. The
time taken from a less than maximum speed will be
proportional.

8.1 Parameters to change for remote Potentiometer speed control
If speed control via the up and down keys is
unsuitable for the application, a remote
Potentiometer can be used instead.
This provides the benefit of allowing motor
speed to be controlled from a more convenient
location such as a cabinet door (if the V20 is
cabinet-mounted) or on the machine itself.
A Potentiometer of more than 5kOhm rating
should be used eg. .10kOhm
The number of turns depends on the
application but both single turn and ten turn
Potentiometers are available from The Inverter
Drive Supermarket at InverterDrive.com.
8.2 Connecting the Potentiometer
A wiring diagram is shown in the illustration
opposite. The most important connection at
the Potentiometer end is the centre terminal or
“wiper”. The wiper will output a variable voltage
between 0 and 10 volts and should be
connected to the AI1 terminal on the Inverter. It
is this voltage which provides the speed signal
with 0V being slowest and 10V fastest.
The default output frequency at 10V is
determined by parameter P2000. The default
output frequency at 0V is determined by P0758
as a percentage of P2000.
If the rotation of the Potentiometer is the
opposite to that required (ie. turn anti-
clockwise to increase speed instead of
clockwise) reverse connections 10V and 0V.
Use screened cable between the Inverter and
Potentiometer. To minimise electromagnetic
interference, ensure the screen is grounded.

9. How to connect and configure a Run Forward or
Run Reverse switch
9.1 Parameters to change for remote Run/Stop
The procedure described in Section 7 enable
Run/Stop operation via the red and green
buttons on the Inverter.
If this is unsuitable for the application, a remote
switch can be used instead.
This section explains how to enable 2-wire
control with Run Forward / Stop / Run Reverse
commands via a single selector switch.
9.2 Connecting the Switch
A wiring diagram is shown in the illustration
opposite. The 24V terminal is a common
connection for terminals DI1 and DI2. Note that
DIC and 0V must be linked (blue wire).
A suitable 3 position NO (Normally Open)
switch should be installed between terminals
DI1, DI2 and 24V. The centre position should
remain open circuit.
When a connection is made between terminals
DI2 and 24V, the motor will run forward. When
terminals DI1 and 24V are connected, the
motor will run in reverse.
If terminals DI1 and DI2 are connected to 24V
at the same time the motor will stop.
