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.

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.

switch should be installed between terminals
SC, X1 and X2. The centre position should
remain open circuit.
When a connection is made between terminals
SC and X1, the motor will run forward. When
terminals SC and X2 are connected, the motor
will run in reverse.
Care should be taken to ensure that terminals
X1 and X2 cannot be connected to SC at the
same time or to each other.

12.2 Connecting the Resistor
A wiring diagram is shown in the illustration

and (+) Terminals on the Inverter. The order of
the connections is unimportant.
The braking resistor may get hot during
operation. Ensure that it is mounted in a
suitable position at least 10cm away from other
items.
It is important that a resistor of the correct
rating is used. Consult the manufacturer’s
manual or product listing on InverterDrive.com
for further information.
B (+)
High inertia loads can cause overvoltage trips
during deceleration and lead to “OE-3" error
messages. In many cases, the solution is to
increase the deceleration time to compensate.
However, if the application requires it, dynamic
braking can be enabled to maintain or reduce
deceleration times by absorbing the energy
generated by such loads.
A Brake Resistor is first installed to absorb
braking energy and dissipate it as heat. The
resistor be correctly sized for both the
Inverter and application.
Then, the “brake chopper” within the Inverter is
enabled. This detects excessive braking
energy and redirects it to the resistor when
required.
