NOTE
LEROY-SOMER reserves the right to modify its product characteristics at any time to incorporate the latest
technological developments. The information contained in this document may therefore be changed without prior warning.
LEROY-SOMER gives no contractual guarantee whatsoever concerning the information published in this document and
cannot be held responsible for any errors it may contain, nor for any damage arising from its use.
CAUTION
For the user's own safety, this frequency inverter must be connected to an approved earth ( B terminal).
Power electronic equipment such as speed controllers, frequency inverters, soft starters, and inverters cannot be used as
circuit-breaking or isolating devices as specified in standard EN 60204 - 1, section 5.
If an accidental start of the installation represents a risk for personnel or the machinery to be driven, it is imperative to supply the
equipment via an isolating device and a circuit-breaking device (power contactor) controllable by an external safety system
(emergency stop, fault detector).
The frequency inverter is fitted with safety devices which can stop the frequency inverter in the event of faults or even stop the
motor. The motor itself can be jammed by mechanical means. Finally, voltage fluctuations, and particularly power cuts, can also
cause the starter to switch off.
The removal of the cause of the shutdown can lead to restarting, with consequent hazard for certain machines or installations.
In such cases, it is essential that the user takes appropriate precautions against restarting when the motor makes an
unscheduled stop.
This equipment meets with existing construction standards. Nonetheless it may cause interference, and the user is responsible
for carrying out the appropriate action to eliminate such interference.
The frequency inverter is designed to power a motor over and above its rated speed (up to 19 times with some settings).
If the motor is not mechanically capable of operating at such speeds, the user risks serious damage arising from mechanical
deterioration of the motor.
Before programming a high speed, it is essential that the user ensures that the motor can tolerate it.
LEROY-SOMER declines all responsibility in the event of the above recommendations not being observed.
.....................................
DANGER
IMPORTANT
Before any intervention, whether to do with the electrics or the mechanics of the installation or machine :
- ensure that the power to the inverter has been switched off (fused isolator or circuit-breaker) and locked manually.
- wait 7 minutes before working on the associated frequency inverter,
- indicates sections in this manual relating to the safety of workers.

1 - GENERAL INFORMATION
1.1 - General operating principle
The synchronous speed (min-1) of a cage induction motor
is a function of the number of poles (P) it has and the
frequency (F) of its power supply. These values are
related by the equation :
Thus, changing the frequency (F) also changes the
synchronous speed (N) of a given motor.
However, changing the frequency without changing the
supply voltage varies the density of magnetic flux in the
motor. FMV 2107 / FMV 2307 inverters cause the
output VOLTAGE and FREQUENCY to vary
simultaneously. This allows optimisation of the motor
torque curve and prevents overheating.
FMV 2107 / FMV 2307 inverters power the motor by
means of a voltage generated from a steady internal
D.C. voltage. Voltage modulation is achieved using the
principle of pulse width modulation (P.W.M.).
This provides the motor with a current close to a sine
wave with few harmonics.
LS MV motors are designed for use with a frequency
inverter. Their magnetic circuits and windings have been
adapted for use with FMV 2107
/ FMV 2307 inverters.
Thus the motor-inverter unit provides guaranteed torque
performances in all types of operating conditions (please
consult LEROY-SOMER).
1.1.1 - Functional description of the variable speed
controller
The variable speed controller comprises :
• A rectifier for the mains supply voltage, along with a
smoothing capacitor to provide a steady D.C. voltage
which depends on the mains supply voltage.
• An inverter : this D.C. voltage supplies power to the
6-transistor inverter (IGBT). The inverter converts the
D.C. voltage to an A.C. voltage which is modulated in
voltage and frequency.
• Three internal current measurements for the D.C.
bus, the inverter output and the braking transistor.
• An electronic control board
comprising : the microprocessor, the ASIC circuit which
generates PWM and the circuits which amplify the
power control signals.
• A console for entering parameters, reading data and
controlling the inverter.

1.4 - Environmental characteristics
1.4.1 - General
b - Installation in a non-ventilated cubicle
The minimum required surface area for heat
exchange is calculated from the following equation :
where :
Pj = loss from all heat-producing equipment (W).
Tj = maximum permissible ambient operating
temperature (°C).
Tamb = maximum ambient external temperature (°C).
k = thermal transmission cœfficient.
S = heat exchange area (m2).
k = 5.5 for 2mm thick sheet steel.
Example : installation of an FMV in a non-ventilated IP 54
cubicle (cubicle placed against a wall).
Pj = 114W (FMV 2107 2,5M) for switching F = 11.7kHz.
Tj = 40°C.
Tamb = 30 °C for example.
k = 5.5.
The calculated heat exchange area is S = 2.07m2and
S = 2 (AB) + AC + BC.
Taking the following values for A and B :
A = 1.8 m (height) - B = 0.6 m (depth),
the minimum calculation for C = 0.39 m.
c - Installation in a ventilated cubicle
If it is possible to use forced ventilation (FV) the size of
the cubicle can be reduced. A minimum space of 100 mm
should be left around the inverter.
The flow rate of FV in m3/h is calculated using the
formula
for the previous example.

3.3 - Electrical and electromagnetic phenomena
associated with frequency inverters
3.3.1 - General
The power structure of frequency inverters leads to the
occurrence of two types of phenomenon :
- low frequency harmonic feedback on the power supply,
- emission of radio frequency signals which may interfere
with the operation of other equipment.
These are separate phenomena, which have different
consequences on the electrical environment.
3.3.2 - Low frequency harmonics
As the diode bridge at the head of the frequency inverter
rectifies the supply voltage it generates a non-sinusoidal
A.C. line current.
3.3.3 - Radio frequency interference
Frequency inverters use high-speed switches
(transistors, semi-conductors) for switching high voltages
(around 550V) and high frequency currents (several
kHz). This provides a high level of efficiency and a low
level of motor noise.
This results in the generation of radio frequency signals
which may disturb the operation of other equipment or
distort sensor measurements :
- due to high frequency leakage currents which escape
to earth via the inverter/motor cable leakage capacitance
This current carries harmonics 6n ±1.
The amplitude of these harmonics decreases as their
frequency increases.
Harmonics 5, 7, 11, and 13 are 250 Hz, 350 Hz, 550 Hz,
650 Hz respectively for a supply frequency of 50 Hz, and
are the most significant.
Their amplitudes depend on the impedance of the mains
supply upstream of the rectifier bridge, and the structure
of the D.C. bus downstream of the rectifier bridge.
The more inductive the mains supply and the D.C. bus,
the more these harmonics are reduced.
They have virtually no effect on the level of electrical
energy consumption. Temperature rises associated with
these harmonics in transformers and motors connected
directly to the mains supply are negligible.
These low frequency harmonics never cause
interference on sensitive equipment.
They may affect the energy distributor due to the
fluctuating resonances which may be present in the
meshed system, and the additional losses in the supply
cables. However these are minor consequences. They
only have a significant effect on loads on frequency
inverters of several hundred kVA and where these
loads are more than a quarter of the total on-site
load.
and the leakage capacitance of the motor across the
metal structures which support the motor.
- by conduction or feedback of radio frequency signals
on the supply cable,
- by direct radiation close to the power supply cable or
the inverter/motor cable.
These phenomena have direct consequences for the
user.
The frequency range concerned (radio frequency) does
not cause interference for the energy distributor.

3.3.4 - Standards
a) Low frequency harmonics
There is no standard for current harmonics
Current harmonics introduce voltage harmonics on the
mains supply. The amplitude of these harmonics
depends on the impedance of the mains supply.
The power distributor who is affected by these
phenomena in the case of high power installations
(see 3.3.2), will have his own recommendations on the
level of voltage harmonics :
b) Radio frequency interference
To prevent interference to sensitive equipment,
European standards EN 50081 and EN 50082 stipulate
the following :
- interference levels below which sensitive equipment is
not affected : the following interference immunity :
EN 50082.1 for domestic equipment,
EN 50082.2 for industrial equipment.
- the maximum levels of interference fed back to the
supply, or radiated by power cables :
EN 50081.1 for domestic equipment,
EN 50081.2 for industrial equipment.
Note on leakage currents
High frequency leakage currents occur as interference
currents on the inverter power supply.
They may reach values above the isolation controller trip
threshold.
Previous standards which set the maximum leakage
current levels for the supply of motors connected directly
3.4 - Wiring instructions
3.4.1 - Earthing ( BB
BB
)
The earth conductor should have as large an area as
possible. The inverter(s) should preferably be placed in a
metal cubicle, mounted on a chassis or conductive metal
frame (unpainted).
Flat braid cables should be used to connect the various
devices to the chassis.
The motor body should be connected directly to the
inverter earth terminal by a standard cross-section earth
cable.
If a shielded connection cable is used between the
inverter and the motor to prevent radiation, the shielding
must be connected at both ends (motor body and
inverter earth terminal)
If the cross-section of the shielding is insufficient, it can
be doubled by a cable running the length of the shielded
- 0.6 % on even harmonic numbers,
- 1 % on uneven harmonic numbers,
- 1.6 % on whole harmonic distortion.
This applies to the power distributor connection point,
and not to each harmonic generator.
Reduction of harmonics fed back to the mains
supply.
The impedance upstream of the rectifier must be
increased by adding mains supply chokes.
Interference immunity
FMV 2107 and FMV 2307 inverters conform to
standards EN 50082.2, these standards are based on
IEC 801.
Radio frequency emission
FMV 2107 and FMV 2307 inverters fitted with RFI
(Radio-Frequency Interference) filters (optional)
conform to standard EN 50081 which is based
essentially on standard VDE 875.
to the 50 Hz supply can no longer be observed when a
frequency inverter is used.
In the absence of any specific standard, European
manufacturers use standard EN 60950 which allows the
leakage current to rise to 5 % of the load current per
phase.
cable, outside the shielding. This cable can be
connected to the same two ends as the shielding. This
cable prevents the circulation of high currents in the
shielding.
The quality of the earth connections must be checked
periodically, as with other power connections.
3.4.2 - Wiring inside cubicles
Do not place power cables and cables carrying
signals next to one another in the same cable trough,
even if the latter are shielded (distance > 0.5m).
Do not place inverter power supply cables next to motor
cables, especially if the inverter is fitted with an RFI filter,
as this would significantly reduce the efficiency of the
filter.

Keep the power supply terminal blocks separate from the

blocks.
Shield sensitive circuits. The shielded cable must be
good quality, with flexible copper wire shielding, and very
tight meshing. Connect the shielding to both ends.
Connect the various devices in a star configuration
directly to the cubicle general earth, as specified in the
safety standards.
Remote control : the remote control relays and
contactors should be fitted with RC circuits.
Control cables
These should be copper, shielded and of a minimum
cross-section of 0.5 mm2.
3.4.3 - Wiring external to cubicles
Power cables should preferably be in steel cableways to
reduce radiation.
If the inverter/motor cable is long (> 20m), it is advisable to
install a suitable choke at the inverter output (SELF - MC) to
reduce high frequency leakage currents, caused by the
cable leakage capacity. This depends on the length of the
cable. The choke should be installed as close as possible to
the inverter (see 7.4).
Power cables
These should be copper multistrand cables with 600V
insulation for A.C. voltages and 1000V for D.C. voltages.
3.4.4 - Installation in a domestic environment
The loads are generally fairly low.
The mains supply is shared by several users.
Other users of the supply may be affected by radio
frequency interference fed back by the inverter to the
mains.
Equipment most sensitive to interference includes : radio
receivers, computers, etc.
A series of steps can be taken to solve the
interference problems on a site. It may not be
necessary to perform them all, as there is no need to
continue once the phenomena have disappeared.
1 - Observe the wiring instructions.
2 - Connect the inverter to the general earth of the
building using a good quality connection : flat cable, as
short as possible.
3 - Make it a priority to install the frequency inverter
close to the motor.
4 - Fit an R.F.I. filter to the inverter to reduce radio
frequency feedback to the mains to a level acceptable to
the standards.
5 - Connect the motor to the frequency inverter using a
shielded cable with the screening connected at both
ends : motor body and inverter earth.
3.4.5 - Installation in an industrial environment
In an industrial environment, it is unlikely that one user
will cause interference to another.
Installing RFI filters at the inverter input, which is often
costly, especially for high power ratings, is not always
the solution.
An in-depth analysis of the problems encountered in an
installation which is currently being used (or an
evaluation of the risks for a future installation) is
essential in order to implement the best technical and
financial solution.
A series of operations can be performed to solve the
interference problems in an installation. It may not
be necessary to perform them all, as there is no
need to continue once the pheneomena have
disappeared.
1 - Observe the wiring precautions.
2 - Interference suppression on probes.
Measurement probes are sensitive devices which may
be affected by interference.
Most problems can be solved by installing small bypass
capacitors (0.1 to 0.5 µF) on the probe feedback signals.
This solution is only possible for D.C. voltage signals
(12, 24 or 48V) or 50 Hz A.C. voltage up to 220V.
3 - Protective devices for sensitive equipment.
If the inverter power rating is significantly higher than
that of sensitive equipment connected to the mains
supply, it is more economical to install an RFI filter on
the supply to the lower rated equipment than to install an
RFI filter on the inverter input. The installation
precautions are the same : filter close to the device,
earth the device using a short connection, keep the filter
input and output wires separate.
4 - 3-phase chokes at the inverter output.
Downstream interference, high frequency leakage currents
are effectively suppressed by installing a suitable 3-phase
choke as close as possible to the inverter output.
5 - R.F.I. filters
If points 2 and 3 do not solve the problems associated
with interference fed back to the mains supply, an RFI
filter should be installed at the frequency inverter input.
6 - Shielded motor cable
The efficiency of this is comparable with standard cables
running through metal cable ducts.
This will significantly limit interference radiated by the
motor cables.
7 - Additional cable on the shielding of the control
electronics.
If these connections have to run through areas where
there is a high degree of interference, it may be
necessary to double the shielding by using an additional
cable connected at both ends in the same way as the
shielding. The circulating currents are thus concentrated
in this cable and not in the shielding of low level
connections.
