NOTE
LEROY-SOMER reserves the right to modify the characteristics of its products at any time in order to incorporate the latest
technological developments. The information contained in this document may therefore be changed without notice.
CAUTION
For the user's own safety, this variable speed drive must be connected to an approved earth terminal).
If accidentally starting the installation is likely to cause a risk to personnel or the machines being driven, it is essential to comply
with the power connection diagrams recommended in this manual.
The variable speed drive is tted with safety devices which, in the event of a problem, control stopping and thus stop the motor. The
motor itself can become jammed for mechanical reasons. Voltage uctuations, and in particular power cuts, may also cause the
motor to stop. The removal of the causes of the shutdown can lead to restarting, which may be dangerous for certain machines or
installations.
In such cases, it is essential that the user takes appropriate precautions against the motor restarting after an unscheduled stop.
The variable speed drive is designed to be able to supply a motor and the driven machine above its rated speed.
If the motor or the machine are not mechanically designed to withstand such speeds, the user may be exposed to serious danger
resulting from their mechanical deterioration.
Before programming a high speed, it is important that the user checks that the installation can withstand it.
The variable speed drive which is the subject of this manual is designed to be integrated in an installation or an electrical machine,
and can under no circumstances be considered to be a safety device. It is therefore the responsibility of the machine manufacturer,
the designer of the installation or the user to take all necessary precautions to ensure that the system complies with current
standards, and to provide any devices required to ensure the safety of equipment and personnel.
LEROY-SOMER declines all responsibility in the event of the above recommendations not being observed.
........................................
This manual only describes the general features, characteristics and installation of the POWERDRIVE MD2CS. For
commissioning, refer to manual ref. 4617.

SAFETY AND OPERATING INSTRUCTIONS FOR VARIABLE SPEED DRIVES
(In accordance with the low voltage directive 2006/95/EC)
Throughout the manual, this symbol warns of
consequences which may arise from inappropriate
use of the drive, since electrical risks may lead to material
or physical damage as well as constituting a re hazard.
1 - General
Depending on their degree of protection, the variable speed
drives may contain unprotected live parts, which may be moving
or rotating, as well as hot surfaces, during operation.
Unjustied removal of protection devices, incorrect use, faulty
installation or inappropriate operation could represent a serious
risk to personnel and equipment.
For further information, consult the documentation.
All work relating to transportation, installation, commissioning
and maintenance must be performed by experienced, qualied
personnel (see IEC 364, CENELEC HD 384 or DIN VDE 0100,
as well as national specications for installation and accident
prevention).
In these basic safety instructions, qualied personnel means
persons competent to install, mount, commission and operate
the product and possessing the relevant qualications.
2 - Use
Variable speed drives are components designed for integration
in installations or electrical machines.
When integrated in a machine, commissioning must not take
place until it has been veried that the machine conforms with
directive 2006/42/EC (Machinery Directive). It is also necessary
to comply with standard EN 60204, which stipulates in particular
that electrical actuators (which include variable speed drives)
cannot be considered as circuit-breaking devices and certainly
not as isolating switches.
Commissioning can take place only if the requirements of the
Electromagnetic Compatibility Directive (EMC 2004/108/EC)
are met.
The variable speed drives meet the requirements of the Low
Voltage Directive 2006/95/EC. The harmonised standards
of the DIN VDE 0160 series in connection with standard VDE
0660, part 500 and EN 60146/VDE 0558 are also applicable.
The technical characteristics and instructions concerning the
connection conditions specied on the nameplate and in the
documentation provided must be observed without fail.
3 - Transportation, storage
All instructions concerning transportation, storage and correct
handling must be observed.
The climatic conditions specied in the technical manual must
be observed.
4 - Installation
The installation and cooling of equipment must comply with the
specications in the documentation supplied with the product.
The variable speed drives must be protected against any
excessive stress. In particular, there must be no damage to
parts and/or modication of the clearance between components
during transportation and handling. Avoid touching the electronic
components and contact parts.
The variable speed drives contain parts which are sensitive to
electrostatic stresses and may be easily damaged if handled
incorrectly. Electrical components must not be exposed to
mechanical damage or destruction (risks to health!).
5 - Electrical connection
When work is performed on variable speed drives which are
powered up, the national accident prevention regulations
must be respected.
The electrical installation must comply with the relevant
specications (for example conductor cross-sections,
protection via fused circuit-breaker, connection of protective
conductor). More detailed information is given in the
documentation.
Instructions for an installation which meets the requirements
for electromagnetic compatibility, such as screening, earthing,
presence of lters and correct insertion of cables and
conductors, are given in the documentation supplied with the
variable speed drives. These instructions must be followed
in all cases, even if the variable speed drive carries the CE
mark. Adherence to the limits given in the EMC legislation is
the responsibility of the manufacturer of the installation or the
machine.
6 - Operation
Installations in which variable speed drives are to be
integrated must be tted with additional protection and
monitoring devices as laid down in the current relevant safety
regulations, such as the law on technical equipment, accident
prevention regulations, etc. Modications to the variable
speed drives using control software are permitted.
Active parts of the device and the live power connections
must not be touched immediately after the variable speed
drive is powered down, as the capacitors may still be charged.
In view of this, the warnings xed to the variable speed drives
must be observed.
Permanent magnet motors generate electrical energy while
they are rotating, even when the drive is switched off. In
this case, the drive continues to be powered by the motor
terminals. If the load is capable of turning the motor, a
switching device must be provided upstream of the motor to
isolate the drive during maintenance operations.
During operation, all doors and protective covers must be
kept closed.
7 - Servicing and maintenance
Refer to the manufacturer’s documentation.
See the Maintenance section in this document.
This manual is to be given to the end user.

GENERAL INFORMATION
1 - GENERAL INFORMATION
1.1 - General
The POWERDRIVE MD2CS is a variable speed drive with
very high performance levels that can be used to control:
- Induction motors without speed sensor (open loop mode
select ) for applications that do not need rated torque
control above 1/10th of the rated speed.
- Asynchronous or synchronous permanent magnet motors
with virtual speed feedback (ux vector mode with software
sensor function ) for applications that require rated torque
control from 1/20th of the rated speed.
Combined with the MDX-ENCODER option, the
POWERDRIVE MD2CS is a drive that can also be used to
control asynchronous or synchronous magnet machines for
applications that require very high dynamic performances,
torque control from zero speed or high speed accuracy
(closed loop vector mode with speed feedback ). The
performance of POWERDRIVE MD2CS is compatible with
use in all 4 quadrants of the torque/speed plane with the
braking module option .
POWERDRIVE MD2CS drives are IP00 protection
products, designed to be installed in a cabinet with
limit access to only habilited and trained personnel. A
line reactor and a surge protection module must be
connected to the drive.

1.4.2 - Derating at low frequency
Measuring the temperature of the power bridges in
conjunction with thermal modelling of the IGBTs protects the
POWERDRIVE MD2CS against overheating.
At low motor frequencies, IGBT modules are subject to tough
temperature cycling, which may reduce their life time. To
prevent this risk, the curve opposite indicates the derating for
output currents Ico and Imax when operating at low motor
frequency in continuous operation.

2.4 - Installation
2.4.1 - General
POWERDRIVE MD2CS drives are IP00 protection
products, designed to be installed in a cabinet with
limit access to only habilited and trained personnel.
POWERDRIVE MD2CS drives must be installed in a clean
environment, away from conducting dust, corrosive gas and
dripping water.
Implementations presented in this document are given
as an indication. It is imperative to respect the cooling
conditions of the product.
To allow proper circulation of air, 250mm minimum must be
maintained between the top of the cabinet and the ceiling. If
several POWERDRIVE MD2CS are installed side by side,
each drive must have at least the surfaces of air inlet and
outlet indicated below.
WARNING:
To ensure correct operation of the drive, it is essential to
follow the instructions given below.
2.4.2 - Air ow
Comply with the min./max. dimensions of the ventilation grids
given on the diagrams below (applicable to a single drive).
Ensure that the air intakes and outlets on the cabinet are
never obstructed, and that the lters on the ventilation grids
permit the air ow rate dened in section 2.6 (recommended
lters: Rittal SK3362 or equivalent).
Depending on the degree of protection of the cabinet (e.g.
IP21, IP54, etc), check that the air ow circulates normally
and that the ow rate is high enough.
If ventilation grids are placed on air outlet, the free space has
to be at least the indicated surface.

INSTALLATION AND MAINTENANCE
Chassis-mounted variable speed drive
MECHANICAL INSTALLATION
To ensure correct operation of the drive, it is essential to
respect dimensions below.
(a): Distance between the roof of the cabinet and an obstacle
(e.g. wall, etc). Several cabinets can be assembled together
(ensure that the air is extracted correctly).
2.4.3 - Temperature
Do not place the drive above a heat source or another drive.
The delta between the internal temperature of the cabinet and
the ambient temperature outside the cabinet must not be
greater than 5°C.
For example, for an ambient temperature of 40°C outside
the cabinet, the internal temperature in the cabinet should
be no more than 45°C. If this is not the case with the
POWERDRIVE MD2CS’s own ventilation, add ventilation
on the cabinet roof (e.g. for a cabinet 600x600, add further
ventilation of at least 225 m3/hr).
The optional braking resistor must be located outside the
cabinet, but as close as possible.

3 - CONNECTIONS
• All connections work must be performed by
qualied electricians in accordance with the laws in
force in the country in which the drive is installed. This
includes earthing to ensure that no directly accessible
part of the drive can be at the mains voltage or any other
voltage which may be dangerous.
• The drive must be supplied through an approved
circuit-breaking device so that it can be powered down
safely.
• The drive power supply must be protected against
overloads and short-circuits.
• Check that the voltage and current of the drive, the
motor and the mains supply are compatible.
• The voltages on the connections of the mains supply,
the motor, the braking resistor or the lter may cause
fatal electric shocks. •
Only one permanent magnet motor can be connected to
the drive output. It is recommended to install a circuit-
breaking device between the permanent magnet motor
and the drive output to eliminate the risk of hazardous
voltage feedback when performing maintenance work.
• See also the recommendations in section 7.
