3.2 Motor connected in DELTA:

The link configuration is shown in the

illustration opposite and is sometimes referred

to as “three-a-breast”.

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.

3.1 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.

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).

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. Pr. 9 = 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 D700 SC 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 D700

SC to control a motor with Run, Stop and

Speed Control from the keypad.

If any of the parameters have been changed

previously, follow the procedure in section 14

to reset the Inverter to Factory Defaults.

7.3 Press the green “RUN” key to start the motor.

The green key will start the motor. The time taken for the

motor to accelerate to the desired speed (in seconds) is

proportional to parameter Pr. 7. The “RUN” indicator will

illuminate to indicate that the motor is running.

To change the speed whilst the motor is running, rotate the

dial to select the new speed and press “SET” to confirm.

The motor will accelerate or decelerate to the new speed.

7.1 Select “MON” and “PU” modes.

With the motor stopped, press the “PU/EXT” key

repeatedly to cycle through operation modes until the

“PU” indicator is illuminated and “0.00" is displayed.

Then, press the “MODE” key repeatedly to cycle through

modes until “MON” is illuminated.

Finally, ensure the display is set to “Hz”. If it is set to “A”

(Amps), use the “SET” key to change to “Hz”.

7.2 Set the desired speed.

Rotate the dial to set the desired speed. In this example,

we have set this to 25.00Hz which is half speed for a

standard 50Hz motor.

Press “SET” to save. The display will alternate between

“F” and your selection for 3 seconds before returning to

0.00 (the current speed). When saving, ensure you don’t

accidentally set the display to “A”. If you do, use the

“SET” key to change back to “Hz”.

7.4 Press the red “Stop” key to stop the motor.

The red key will stop the motor. The time taken (in seconds)

to stop the motor is proportional to parameter Pr. 8.

Note: if you would prefer to continually adjust the speed

using the dial (rather than confirming with set each time)

change parameter Pr. 161 to 1.

8. How to enable Sensorless Vector mode

Page 8

This guide has been produced by The Inverter Drive Supermarket Ltd.

Drive Supermarket and must not be reproduced or altered without prior written permission.

The standard motor control mode of the D700

SC Inverter is VxF. This simple mode controls

motor speed by varying Volts and Frequency in

a specific ratio to maintain output torque.

The D700 SC can also operate in Sensorless

Vector mode. This can improve motor

performance without requiring a separate

feedback device. Sensorless Vector mode

operates in the same way as VxF but performs

a number of calculations to improve low speed

torque.

These calculations require an “auto tuning” run

during which the Inverter operates for approx.

10s to gather the necessary data. The shaft

does not turn.

To enable sensorless vector control first set the

parameter values specified in 8.1 and then

perform the auto tuning run described in 8.2

and 8.3.

The motor shaft does not turn during auto

tuning.

8.2 Enable monitoring and start auto tuning.

Once the parameters in 8.1 have been set, check that the

operation mode is set to “PU”. If not, use the “PU/EXT”

key to cycle through operation modes.

The display will show 11 to indicate that the Inverter is

ready for tuning. Press “RUN” to begin tuning.

The display will show 12 whilst tuning is in progress.

Note: If “Er. 4" is displayed ensure that the operation

mode is set to PU (see above) then press RUN again.

8.3 Auto tuning is complete.

The tuning process will take approx. 10 seconds during

which excitation noise will be heard from the motor.

When the process is complete, the display will show 13 to

9. How to connect and configure a Potentiometer

for remote speed control

Parameter

Description

How to set

Pr. 59

Remote setting function

Default is 0. Set to to enable frequency setpoint via Analogue input terminal 2.1

Pr. 73

Analogue input selection

Set to for 5V (default).1

Pr. 79

External operation mode

Set to to use the Potentiometer as the speed reference with Start/Stop via Inverter keypad.4

Set to 0 to use the Potentiometer as the speed reference with Start/Stop via external controls.

9.1 Parameters to change for remote Potentiometer speed control

If speed control via the integrated 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 D700 SC

is cabinet-mounted) or on the machine itself.

A Potentiometer of rating should be1kOhm

used.

The number of turns depends on the

application. A single turn Potentiometer is

available from The Inverter Drive Supermarket

at InverterDrive.com.

9.2 Connecting the Potentiometer

First, ensure the Voltage/Current Input switch

is set to “V” (Voltage).

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 5 volts and should be

connected to the “2" terminal on the Inverter. It

is this voltage which provides the speed signal

with 0V being slowest and 5V fastest.

The default output frequency at 0V is the

minimum frequency of the Inverter. To change

this, edit Parameter 2. The default output

frequency at 5V is 50Hz. To change this, edit

Parameter 125.

If the rotation of the Potentiometer is the

opposite to that required (ie. turn anti-

clockwise to increase speed instead of

clockwise) reverse connections 10 and 5.

Use shielded SY cable between Potentiometer

and Inverter and ensure that the cable screen

is connected to the Inverter earth terminal.
