2. INTRODUCTION
PRODUCT DESCRIPTION AND
APPLICATIONS
The MICROMASTER Eco and MIDIMASTER Eco
provides a range of variable frequency speed
controllers (inverters) specifically developed for
the Heating, Ventilation & Air Conditioning
(HVAC) industry.
Key design features include:
•Automatic energy optimisation
•Motor thermal overload protection
•Automatic switching frequency optimisation for
minimised acoustic noise generation
•Zero de-rating of motor
•Automatic motor tuning at switch-on
•Earth fault protection
•Short circuit protection
•Built-in chokes allow use of up to 150 metre
motor cables
The ability to easily control the speed of pump or
fan motors provides superior regulation and
control of the process, enabling optimisation of
room temperatures and personal comfort levels.
The Eco range combines ease of installation and
commissioning with low maintenance and
operating costs. In addition, the specific HVAC
product functionality (compared with similar
products aimed at “Hi-Tech” multiple applications)
means that product costs can be minimised, and
the user does not pay for features which are not
required.
Day-to-day operating costs can be drastically
reduced - up to 60% in some applications. Energy
consumption and associated emissions are also
reduced to the lowest possible levels.
ECO OPERATING INSTRUCTION
MANUAL
The Eco Operating Instructions booklet (which
should be read in conjunction with this manual)
provides basic information on equipment
installation and programming, to control the
functions of fans and pump motors. It is aimed at
HVAC Installation Technicians and Electricians
working and commissioning on-site, and is
intended to provide a quick, straightforward guide
to installing and simple operating of the Eco units.
ECO REFERENCE MANUAL
This Manual - The Eco Reference Manual is
intended for use by a wide range of HVAC
professionals. For example, the Eco Reference
Manual is to be used by Building Automation
Engineers to plan their equipment and cabling
schedules and estimate their material
requirements. HVAC Consultants may also use it
in order to compile the relevant portions of their
tender specification.
The Eco Reference Manual should also be useful
to electrical panel builders, building automation
control engineers, quantity surveyors / estimators,
electrical project managers, and maintenance
contractors.

3. PRINCIPLES OF INVERTER OPERATION
INTRODUCTION
This section of the manual is intended to help
first-time users of variable speed drives to
understand basic principles of operation, and gain
some insight into successful installation and
application of the MICROMASTER Eco range of
Variable Speed Drives.
VARIABLE SPEED DRIVES
A Variable Speed Drive (VSD) system consists of
a Motor and some form of speed controller.
History
Early electric VSDs consisted of AC and DC
motor combinations which were used as rotating
AC to DC converters. The DC supply was used to
drive the DC motor at variable speed by
controlling the field current in the DC generator to
vary the DC voltage to the DC motor.
The first electronic controllers used Thyristor
(SCR) Rectifiers which controlled the voltage, and
therefore the speed of DC motors. These DC
VSDs are still widely used and offer very
sophisticated control capability. However, the DC
motor is large, expensive and requires periodic
brush maintenance.
Present day
The AC induction motor is simple, low cost,
reliable and widely used throughout the world. In
order to control the speed of an AC induction
motor a more complex controller, which varies
the frequency as well as the voltage, usually
called an inverter is required.
Induction motor
In order to understand how an inverter works, it is
first necessary to understand how an induction
motor works.
An asynchronous induction motor works like a
transformer. When the stator (the fixed, outer
winding) is connected to a three phase power
source, a magnetic field which rotates at the
frequency of the supply is set up.

This field crosses the air gap between the stator
and rotor and causes currents to flow in the rotor
windings. This produces a force (torque) on the
rotor as the current interacts with the changing
magnetic field, and the rotor turns.
If the windings are arranged in several pairs (or
poles), the frequency of the rotating field will be
less than the applied frequency (e.g. two pole =
50/60Hz = 3000/3600 rpm, but four pole =
50/60Hz = 1500/1800 rpm).
However, if the rotor runs at the same speed as
the rotating field, there will be no changing
magnetic field, and therefore no torque.
Since rotor currents must be induced in order to
create output torque, the rotor always runs a little
slower than the rotating field. This difference in
speed is known as slip and is generally about 3%.

Torque Speed Characteristic of An Induction Motor
The speed of the motor depends on the applied
frequency, as well as the winding arrangement,
and to some extent on the load.
Therefore in order to control the motor speed it is
necessary to control the frequency of the supply.
If the frequency is reduced, the voltage must be
reduced, or the stator current and magnetic flux
will be too high and the motor’s magnetic field will
saturate. Hence the voltage must be controlled as
well.
If the frequency is increased above normal, more
voltage would normally be needed to maintain
maximum flux; this is not usually possible, so less
torque is available at high speed, (i.e. speeds
above the supply frequency).

Therefore in order to control the speed of a
standard AC motor, the applied frequency and
voltage must be controlled.
The use of a standard induction motor together
with a variable frequency speed controller allows
a cost effective speed control system to be built.

VARIABLE FREQUENCY INVERTER.
An electronic converter which converts Direct
Current (DC) to Alternating Current (AC) is known
as an inverter. Electronic speed controllers for AC
motors usually convert the AC supply to DC using
a rectifier, and then convert it back to a variable
frequency, variable voltage AC supply using an
inverter bridge. The connection between the
rectifier and inverter is called the DC link. The
block diagram of a speed controller (often called
an inverter) is shown below:
Inverter Block Diagram
Supply
Rectifier DC Link Inverter
CC

ECO REFERENCE MANUAL
3-5
The three phase supply is fed into a full wave
rectifier which supplies the DC link capacitors.
The capacitors reduce the voltage ripple
(especially on single phase supplies) and supply
energy for short mains breaks. The voltage on
the capacitors is uncontrolled and depends on the
peak AC supply voltage.
MICROMASTER Eco &
MIDIMASTER Eco inverters are
available as three phase.
The DC voltage is converted back to AC using
Pulse Width Modulation (PWM). The desired
waveform is built up by switching the output
transistors (Insulated Gate Bipolar Transistors;
IGBTs) on and off at a fixed frequency (the
switching frequency). By varying the on and off
time of the IGBTs the desired current can be
generated. The output voltage is still a series of
square wave pulses and the inductance of the
motor windings results in a sinusoidal motor
current. Pulse Width Modulation is shown in the
figure below.

WEAR & TEAR
Eco inverters can make possible greatly reduced
maintenance and running costs:
•Fewer stop/start sequences means that
mechanical stresses are reduced.
•Equipment life is extended, and a smaller
number of components require reduced
degree of maintenance
•Reduced airflow means reduced cleaning.
•Reduction in replacement of maintenance
consumables such as fan belts, motor
bearings and fan bearings.

EQUIPMENT RATIONALISATION
Using Eco inverters can significantly reduce the
number of system components and often enable
valuable space to become available:
•Mechanical components which may be
eliminated include dampers, actuators, (and
outstations by using serial communication).
•Reductions in the use of electrical contactors,
control and overload relays, terminals and PID
modules can be achieved. Also, control panel
complexity is reduced, as is wiring and labour
costs.
