Notes:

The illustration above is based on the frame

size B model (0.75kW). The terminal layout for

sizes A, C and D (0.37kW, 1.5kW and 2.2kW is

similar.

The order of the three phases determines the

direction the motor turns.

Important:

Use screened SY cable between the Inverter

and Motor to minimise electromagnetic

interference.

Ensure the motor cable screen is earthed at

the motor end.

Before commencing, confirm that the Inverter and

all cables are completely isolated from the power

supply, have been isolated for at least 5 minutes

and that the motor is not turning.

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.

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

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. s2.04 = 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 EFC 3600 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 EFC

3600 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 13

to reset the Inverter to Factory Defaults.

6.1 Find Parameter Groups.

This example demonstrates the steps required to set

parameter b1.05 which is Maximum Frequency.

Press the “Func” key repeatedly until the display shows

“-b0-” (shown in the illustration opposite).

6.2 Find a Parameter Group eg. b1

There are a total of 12 parameter groups when

“Advanced Parameters” are enabled:-

Some parameter groups may be hidden when “Advanced

Parameters” are not enabled. Press “Set” to select “-b1-”.

6.3 Find a Parameter eg. b1.05

The display will show “b1.00" to indicate parameter 00

within group b1.

Use the up and down keys to navigate to parameter

b1.05. Press the “Set” key to modify the parameter value.

Note that in some cases, the value of a parameter can be

restricted by the value of another parameter.

6.4 Change a Parameter value.

Use the up and down keys to increase or decrease the

value. Press and hold the up or down key to change the

value more quickly.

Press the “Set” key to save changes. The display will

show the next available parameter.

Press “Func” twice to exit.

7.1 Use the dial to set the required speed.

The display will change to show the current speed

reference in Hz.

The minimum speed reference is defined by parameter

b1.07 and the maximum reference by b1.06.

7.2 Press the green “Run” button to start the motor.

Press the green button firmly to start the motor. The motor

will accelerate to the speed set in 7.1 (above) in the time

defined by parameter b1.20.

Motor speed can be changed whilst the motor is running by

rotating the dial clockwise (faster) or anti-clockwise

(slower). When the motor is running, the “Run” lamp will be

illuminated.

7.3 Press the red “Stop” button to stop the motor.

The red button will stop the motor.

The time taken (in seconds) to stop the motor is determined

by parameter b1.21.

8.1 Parameters to change for remote Potentiometer speed control

If the integrated dial on the keypad 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 EFC

3600 is cabinet-mounted) or on the machine

itself.

A Potentiometer of rating should be

used.

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.

10kOhm

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 Vr1 terminal at the Inverter

end. It is this voltage which provides the speed

signal with 0V being slowest and 10V fastest.

The default output frequency at 0V is 0Hz. To

change this, edit Parameter E0.22. The default

output frequency at 10V is 50Hz. To change

this, edit Parameter E0.24.

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

GND.

Use shielded SY cable between Potentiometer

and Inverter and ensure that the cable screen

is connected to the earth IO terminal.
