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 is therefore liable to be changed without notice.
WARNING
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, can also cause the
motor to stop. The removal of the causes of the shutdown can lead to restarting, which could 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 could 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.

SAFETY AND OPERATING INSTRUCTIONS FOR VARIABLE SPEED DRIVES
(In accordance with the low voltage directive 2014/35/EU)
Throughout the manual, this symbol warns of consequences which can arise from inappropriate use of the drive, since
electrical risks can lead to material or physical damage as well as constituting a re hazard.
1 - General information
Depending on their degree of protection, variable speed drives
can contain unprotected live parts, which can 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 manual.
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 2014/30/EC) are
met.
The variable speed drives meet the requirements of the Low
Voltage Directive 2014/35/EU. The harmonized 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 manual supplied with the product.
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.
Variable speed drives contain parts that are sensitive to
electrostatic stresses and can easily be 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 that 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 manual.
Instructions for an installation which meets the requirements
for electromagnetic compatibility, such as screening, earthing,
presence of lters and correct laying 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 could 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.

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.

With the minimum inductance values of the above table the total current harmonic distortion (THD) on the line feeding the drive
is less than 35% (normal duty use). If a lower current harmonic level is requested, MD2CS 340T to 570T and MD2CS 270TH to
500TH offer the possibility to insert an additional Dc choke between terminals Lc1 and Lc2. In normal use Lc1 and Lc2 need to be
linked by the cables included in the drive package.
1.4.4 - Surge protection
For electrical systems that present high overvoltage transients, surge protection devices have to be connected between each line
phases and the ground as recommended in section 3
Protection device characteristics:
• Nominal voltage : 550V
• Minimum energy : 300 Joules
• Nominal unloaded current : 15 kA

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.

en
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.
For surrounding temperature of 40°C or 50°C, 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.

• 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.
