Environmental Statement
LEROY-SOMER is committed to minimising the environmental impacts of its manufacturing
operations and of its products throughout their life cycle. To this end, we operate an Environmental
Management System (EMS) which is certified to the International Standard ISO 14001.
The electronic variable speed drives manufactured by LEROY-SOMER have the potential to save
energy and (through increased machine/process efficiency) reduce raw material consumption and
scrap throughout their long working lifetime. In typical applications, these positive environmental
effects far outweigh the negative impacts of product manufacture and end-of-life disposal.
Nevertheless, when the products eventually reach the end of their useful life, they can very easily be
dismantled into their major component parts for efficient recycling. Many parts snap together and can
be separated without the use of tools, while other parts are secured with conventional screws.
Virtually all parts of the product are suitable for recycling.
Product packaging is of good quality and can be re-used. Large products are packed in wooden
crates, while smaller products come in strong cardboard cartons which themselves have a high-
recycled fibre content. If not re-used, these containers can be recycled. Polythene, used on the
protective film and bags from wrapping product, can be recycled in the same way. LEROY-SOMER's
packaging strategy favours easily recyclable materials of low environmental impact, and regular
reviews identify opportunities for improvement.
When preparing to recycle or dispose of any product or packaging, please observe local legislation
and best practice.

1 Safety Information
1.1 Warnings, Cautions and Notes
1.2 Electrical Safety - general warning
The voltages used in the drive can cause severe electrical shock and/or burns, and
could be lethal. Extreme care is necessary at all times when working with or adjacent to
the drive.
Specific warnings are given at the relevant places in this guide.
1.3 System design and safety of personnel
The drive is intended as a component for professional incorporation into complete
equipment or system. If installed incorrectly, the drive may present a safety hazard.
The drive uses high voltages and currents, carries a high level of stored electrical
energy, and is used to control equipment which can cause injury.
System design, installation, commissioning and maintenance must be carried out by
personnel who have the necessary training and experience. They must read this safety
information and this guide carefully.
The STOP and START controls or electrical inputs of the drive must not be relied
upon to ensure safety of personnel. They do not isolate dangerous voltages from
the output of the drive or from any external option unit. The supply must be
disconnected by an approved electrical isolation device before gaining access to
the electrical connections.
The drive is not intended to be used for safety-related functions.
Careful consideration must be given to the function of the drive which might result in a
hazard, either through its intended behaviour or through incorrect operation due to a
fault. In any application where a malfunction of the drive or its control system could lead
to or allow damage, loss or injury, a risk analysis must be carried out, and where
necessary, further measures taken to reduce the risk - for example, an over-speed
protection device in case of failure of the speed control, or a fail-safe mechanical brake
in case of loss of motor braking.
1.4 Environmental Limits
Instructions within the supplied data and information within the Digidrive SK Technical
Data Guide regarding transport, storage, installation and the use of the drive must be
complied with, including the specified environmental limits. Drives must not be
subjected to excessive physical force.
A Warning contains information, which is essential for avoiding a safety hazard.

1.5 Access
Access must be restricted to authorised personnel only. Safety regulations which apply
at the place of use must be complied with.
The IP (Ingress Protection) rating of the drive is installation dependant. For further
information, refer to the Digidrive SK Technical Data Guide.
1.6 Compliance and regulations
The installer is responsible for complying with all relevant regulations, such as national
wiring regulations, accident prevention regulations and electromagnetic compatibility
(EMC) regulations. Particular attention must be given to the cross-sectional areas of
conductors, the selection of fuses and other protection, and protective earth (ground)
connections.
The Digidrive SK EMC Guide contains instructions for achieving compliance with
specific EMC standards.
Within the European Union, all machinery in which this product is used must comply
with the following directives:
98/37/EC: Safety of machinery
89/336/EEC: Electromagnetic compatibility
1.7 Motor
Ensure the motor is installed in accordance with the manufacturer's recommendations.
Ensure the motor shaft is not exposed.
Standard squirrel cage induction motors are designed for single speed operation. If it is
intended to use the capability of a drive to run a motor at speeds above its designed
maximum, it is strongly recommended that the manufacturer is consulted first.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective. The motor should be fitted with a protection thermistor. If necessary, an
electric force vent fan should be used.
The values of the motor parameters set in the drive affect the protection of the motor.
The default values in the drive should not be relied upon.
It is essential that the correct value is entered into parameter 06, motor rated current.
This affects the thermal protection of the motor.
1.8 Adjusting parameters
Some parameters have a profound effect on the operation of the drive. They must not
be altered without careful consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due to error or tampering.
1.9 Electrical installation
1.9.1 Electric shock risk
The voltages present in the following locations can cause severe electric shock and may
be lethal:
• AC supply cables and connections
• DC bus, dynamic brake cables and connections
• Output cables and connections
• Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single insulated and must not be
touched.

Information
1.9.2 Isolation device
The AC supply must be disconnected from the drive using an approved isolation device
before any cover is removed from the drive or before any servicing work is performed.
1.9.3 STOP function
The STOP function does not remove dangerous voltages from the drive, the motor or
any external option units.
1.9.4 Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the
AC supply has been disconnected. If the drive has been energised, the AC supply must
be isolated at least ten minutes before work may continue.
Normally, the capacitors are discharged by an internal resistor. Under certain, unusual
fault conditions, it is possible that the capacitors may fail to discharge, or be prevented
from being discharged by a voltage applied to the output terminals. If the drive has failed
in a manner that causes the display to go blank immediately, it is possible the capacitors
will not be discharged. In this case, consult LEROY-SOMER or their authorised
distributor.
1.9.5 Equipment supplied by plug and socket
Special attention must be given if the drive is installed in equipment which is connected
to the AC supply by a plug and socket. The AC supply terminals of the drive are
connected to the internal capacitors through rectifier diodes which are not intended to
give safety isolation. If the plug terminals can be touched when the plug is disconnected
from the socket, a means of automatically isolating the plug from the drive must be used
(e.g. a latching relay).
1.9.6 Ground leakage current
The drive is supplied with an internal EMC filter capacitor fitted. If the input voltage to
the drive is supplied through an ELCB or RCD, these may trip due to the ground
leakage current. See section 4.3.1 Internal EMC filter on page 14 for further information
and how to disconnect the internal EMC capacitor.

If DIN rail mounting is used in an installation where the drive is to be subjected to shock
or vibration, it is recommended that the bottom mounting screws are used to secure the
drive to the back plate.
If the installation is going to be subjected to heavy shock and vibration, then it is
recommended that the drive is surface mounted rather than DIN rail mounted.
NOTE
The DIN rail mounting mechanism has been designed so no tools are required to install
and remove the drive from a DIN rail. Please ensure the top mounting lugs are located
correctly on the DIN rail before installation is initiated.

Braking resistor: High temperatures and overload protection
Braking resistors can reach high temperatures. Locate braking resistors so that damage
cannot result. Use cable having insulation capable of withstanding the high temperatures.
It is essential that the braking resistor be protected against overload caused by a failure
of the brake control. Unless the resistor has in-built protection, a circuit like those shown
in
Figure 4-1 and Figure 4-2 should be used, where the thermal protection device
disconnects the AC supply to the drive. Do not use AC relay contacts directly in series
with the braking resistor circuit, because it carries DC.
WARNING
When connecting single phase to a dual rated 200V unit, use terminals L1 and L3.
NOTE
For control terminal connections, see Pr 05 on page 23.

It is recommended that the internal EMC filter is kept in place unless there is a specific
reason for removing it.
If the drive is to be used on an IT supply, then the filter must be removed.
The internal EMC filter reduces radio-frequency emissions into the mains supply. Where
the motor cable is short, it permits the requirements of EN61800-3 to be met for the
second environment.
For longer motor cables, the filter continues to provide a useful reduction in emission
level, and when used with any length of shielded cable up to the limit for the drive, it is
unlikely that nearby industrial equipment will be disturbed. It is recommended that the
filter be used in all applications unless the ground leakage current is unacceptable or
the above conditions are true.
The above leakage currents are just the leakage currents of the drive with the internal EMC
filter connected and do not take into account any leakage currents of the motor or motor cable.
NOTE
In both cases, there is an internal voltage surge suppression device connected to
ground. Under normal circumstances, this carries negligible current.
NOTE
When the internal EMC filter is fitted, the leakage current is high. In this case, a
permanent fixed ground connection must be provided using two independent conductors
each with a cross-section equal to or exceeding that of the supply conductors. The drive
is provided with two ground terminals to facilitate this. The purpose is to prevent a safety
hazard occurring if a connection is lost.

4.3.2 Removing the internal EMC filter
Figure 4-3 Removal and re-fitting of internal EMC filter
4.3.3 Further EMC precautions
Further EMC precautions are required if more stringent EMC emission requirements apply:
• Operation in the first environment of EN 61800-3
• Conformity to the generic emission standards
• Equipment which is sensitive to electrical interference operating nearby
In this case it is necessary to use:
• The optional external EMC filter
• A screened motor cable, with screen clamped to the grounded metal panel
• A screened control cable, with screen clamped to the grounded metal panel
A full range of external EMC filters is also available for use with Digidrive SK.

The control circuits are isolated from the power circuits in the drive by basic insulation
(single insulation) only. The installer must ensure that the external control circuits are
insulated from human contact by at least one layer of insulation (supplementary
insulation) rated for use at the AC supply voltage.
WARNING
If the control circuits are to be connected to other circuits classified as Safety Extra Low
Voltage (SELV) (e.g. to personal computer), an additional isolating barrier must be
included in order to maintain the SELV classification.
WARNING
The above warnings also apply to the PCB edge connector for the optional Solutions
Modules. To allow a Solutions Module to be fitted to Digidrive SK, a protective cover must
be removed to allow access to the PCB edge connector. See Figure 3-3 on page 11. This
protective cover provides protection from direct contact of the PCB edge connector by the
user. When this cover is removed and a Solutions Module fitted, the Solutions Module
provides the protection from direct contact by the user. If the Solutions Module is then
removed, this PCB edge connector becomes exposed. The user is required to provide
protection in this case, to protect against direct contact of this PCB edge connector.

Information
If the enable terminal is opened, the drive’s output is disabled and the motor will coast to
a stop. The drive will not re-enable for 1.0s after the enable terminal is closed again.
*Following a drive trip, opening and closing the enable terminal will reset the drive. If the
run forward or run reverse terminal is closed, the drive will run straight away.
**Following a drive trip and a reset via the stop/reset key, the enable, run forward or run
reverse terminals will need to be opened and closed to allow the drive to run. This
ensures that the drive does not run when the stop/reset key is pressed.
The enable, run forward and run reverse terminals are level triggered apart from after a
trip where they become edge triggered. See * and ** above.
If the enable and run forward or enable and run reverse terminals are closed when the
drive is powered up, the drive will run straight away up to a set speed.
If both the run forward and run reverse terminals are closed, the drive will stop under the
control of the ramp and stopping modes set in Pr 30 and Pr 31.

5.3 Selecting and changing parameters
Figure 5-2
When in Status mode, pressing and holding the MODE key for 2 seconds will
change the display from displaying a speed indication to displaying load indication and
vice versa.
Pressing and releasing the MODE key will change the display from status mode to
parameter view mode. In parameter view mode, the left hand display flashes the
parameter number and the right hand display shows the value of that parameter.
Pressing and releasing the MODE key again will change the display from parameter
view mode to parameter edit mode. In parameter edit mode, the right hand display
flashes the value in the parameter being shown in the left hand display.
Pressing the MODE key in parameter edit mode will return the drive to the
parameter view mode. If the MODE key is pressed again then the drive will return to
status mode, but if either of the up or down keys are pressed to change the
parameter being viewed before the MODE key is pressed, pressing the MODE
key will change the display to the parameter edit mode again. This allows the user to
very easily change between parameter view and edit modes whilst commissioning the
drive.
This procedure is written from the first power up of the drive and assumes no terminals
have been connected, no parameters have been changed and no security has been set.
