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.

8. How to enable Sensorless Vector mode
Page 8

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.

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.

buttons on the Inverter keypad.
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.
The Inverter must be in “EXT” control mode to
operate from the I/O terminals. Press PU/EXT
to select.
10.2 Connecting the Switch
A wiring diagram is shown in the illustration
opposite.
The PC terminal is a common connection for
terminals RL, RM, RH, STF and STR when the
jumpers are set in “Source” (the default). If the
jumpers have been changed to “Sink”, use SD
as the common instead.
A suitable 3 position NO (Normally Open)
switch should be installed between terminals
PC, STF and STR. The centre position should
remain open circuit.
When a connection is made between terminals
PC and STF, the motor will run forward. When
terminals PC and STR are connected, the
motor will run in reverse.
If terminals STF and STR are connected to PC
at the same time the motor will stop.
The Inverter must be in external control mode to
operate in 3-wire control. Check that the “EXT”
indicator is illuminated to confirm. The PU/EXT key
can be used to change the mode if required.

The PC terminal is a common connection for
terminals RL, RM, RH, STF and STR when the
jumpers are set in “Source” (the default). If the
jumpers have been changed to “Sink”, use SD as
the common instead.
Two suitable 2 position NO (Normally Open)
switches should be installed: One between
terminals PC and STF (Run/Stop) and the other
between terminals PC and STR
(Forward/Reverse).
Note that the Forward/Reverse switch only selects
the direction of rotation - it will not start or stop the
motor. The direction can be set either before the
motor is started or whilst it is running.
If the application only requires the motor to turn in
one direction, the Forward/Reverse switch can be
omitted.
The Inverter must be in external control mode to
operate in 3-wire control. Check that the “EXT”
indicator is illuminated to confirm. The PU/EXT key
can be used to change the mode if required.

12.2 Connecting the Switches
The PC terminal is a common connection for
terminals RL, RM, RH, STF and STR when the
jumpers are set in “Source” (the default). If the
jumpers have been changed to “Sink”, use SD as
the common instead.
For “Run” and “Stop”, two suitable pushbuttons
should be installed. The “Run” pushbutton should
include a Normally Open contact between
terminals RL and STF and the “Stop” a Normally
Closed contact between RL and PC.
For “Forward/Reverse” a suitable 2 position NO
(Normally Open) switch should be installed
between RL and STR. A momentary connection
between RL and STF will start the motor. It will
continue to run until the connection between RL
and PC is broken.
Note that the Forward/Reverse switch can only be
used to set the direction when the motor is stopped.
It will not change the direction once the motor is
running. If this is not suitable, an alternate 3-wire
configuration with Run Forward, Run Reverse and
Stop is possible - refer to the manual for details.
The Inverter must be in external control mode to
operate in 3-wire control. Check that the “EXT”
indicator is illuminated to confirm. The PU/EXT key
can be used to change the mode if required.

13.1 Parameters to change for Dynamic Braking
13.2 Connecting the Resistor
A wiring diagram is shown in the illustration
opposite. Connect the brake resistor to the PR
and P/+ terminals on the Inverter. The order of
the connections is unimportant.
The braking resistor may get hot during
operation. Ensure that it is suitably-mounted
so any heat generated will not affect other
equipment. Some resistors may include a
thermal relay for additional protection.
It is essential that a resistor of the correct rating
is used. Consult the product manual issued by
the manufacturer or product listing on
InverterDrive.com for further information.
Note: Some smaller D720S Inverters do not
have integrated dynamic braking. The
illustration opposite is based on the 230V
Single Phase frame size at 0.75kW. Other
ratings and frame sizes are similar.
PR P/+
High inertia loads can cause overvoltage trips
during deceleration and lead to “E.OV3" 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 themust
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.
