2. Motor Connections - Star and Delta

Dual voltage induction motors typically include terminal boxes with six points. The points 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).

Link

Phase

STAR

Earth

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).

2.1 Motor connected in STAR (or Wye):

For safety purposes, Star (shown opposite) is the default configuration for new motors 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 motor to be changed to back in future.

The order of the three phases determines the direction the motor turns.

Note that the cable screen and earth are connected together at the earth terminal.

The link configuration is shown in the illustration opposite and is sometimes referred to a “three-a-breast”.

The LS SV-iC5 converts Single Phase 230V to Three Phase 230V so a 230/400V Motor should be connected in Delta.

The order of the three phases determines the direction the motor turns.

3. Parameters - overview

The iC5 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. H21 = Max Output Frequency) with a description available in the manual.

The parameters contain critical information essential to the correct operation of the iC5. Therefore, they should at least be checked by the user before it is operated for the first time.

The parameters listed in section 4 are intended to provide a starting point to allow for basic operation of the iC5 Inverter.

4. Parameters to set before use

Set the following parameters to allow the iC5 to run in standard mode with Run, Stop and Speed Control from the integral keypad.

See section 6 for an explanation of Parameter Groups

and to learn how to set a parameter value.

4.1 Parameters in the Drive Group

Press left/right to find 0.0 then up/down to find parameter number

If any of the parameters have been changed previously, follow the procedure in section 12 to reset the iC5 to Factory Defaults.

5. How to set “Motor no-load current” - H34

Motor no load current is an important parameter to set to get the best possible motor performance.

The procedure involves running the motor offload at it’s rated speed and making a note of output current. This value is then set in

parameter H34. Correctly set, it allows the Inverter to maintain the precise output current to suit the motor and significantly improves torque at lower speeds.

Once set, this can be confirmed by running the

motor off-load at 50Hz and 5Hz and noting that

the output current is the same in both cases.

5.1 How to determine “Motor no-load current” by operating the iC5.

5.1.1 Use the dial to set the frequency to 50Hz and start the motor.

FWD REV

Motor no-load current can only be determined with the motor running off-load. Decouple the motor from the

RUN STOP/RST

machine before beginning!

Turn the dial clockwise until the display shows 50.0 as

illustrated opposite. Then press the green “Run” button to start the motor. As the motor accelerates the display will track frequency from 0.0 to 50.0.

Once the Inverter has reached 50.0Hz proceed to the step below.

5.1.2 Use the navigation pad to locate the “CUr” parameter.

Press the down arrow on the navigation pad until “CUr” is displayed (as shown opposite). “CUr” is a read-only parameter which displays output current in Amps.

Press the navigation pad to select “Cur”. The output current will be displayed.

Make a note of this value. It is “Motor no-load current” in Amps and must be set in parameter H34.

8. How to enable Sensorless Vector Mode

The standard operating mode of the iC5 Inverter is VxF. This is the simplest form of operation and controls Volts and Frequency to vary the speed of a standard Induction Motor.

Sensorless Vector mode operates in the same

way as VxF but performs a number of

calculations to improve low speed torque.

This requires an “ID” run during which the

Inverter runs the motor for approx. 1 minute at The iC5 can also operate in Sensorless Vector mode. This can improve motor performance without requiring a separate feedback device.

Decouple the motor from the machine

before starting an ID run.

9. How to connect and configure a Potentiometer for remote speed control

If the integrated speed control dial 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 iC5 is cabinet-mounted) or on the machine itself.

A Potentiometer of rating should be

9.2 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 V1 terminal at the Inverter

end. It is this voltage which provides the speed

signal with 0V being slowest and 10V fastest.

10. How to connect and configure a Run/Stop switch

The parameters described in Section 4 enable Run/Stop operation via the red and green buttons on the Inverter. If this is unsuitable for the application, a remote Run/Stop switch can be used instead.

Note that once this procedure is complete, the

Run/Stop buttons on the Inverter can no longer

be used.

and NOT the P1 power terminal.

When the P1 terminal receives 24V (ie. when

the circuit with CM is complete), Run is

it receives 0V (ie. when the circuit with CM is

broken), Run is disabled and the motor will
