(usually to 3kW) and is sometimes known as

“two at one side”.

Only two links are required for Star. Double-up

the links if changing from Delta to allow the

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

Y (Wye).

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.

Siemens V20 Series Inverter

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.
