General Information
The manufacturer accepts no liability for any consequences resulting from inappropriate,
negligent or incorrect installation or adjustment of the optional parameters of the equipment or
from mismatching the variable speed drive with the motor.
The contents of this guide are believed to be correct at the time of printing. In the interests of
commitment to a policy of continuous development and improvement, the manufacturer
reserves the right to change the specification of the product or its performance, or the content
of the guide without notice.
All rights reserved. No parts of this guide may be reproduced or transmitted in any form or by
any means, electrical or mechanical including, photocopying, recording or by an information
storage or retrieval system, without permission in writing from the publisher.
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 must not be
discarded but should instead be recycled by a specialist recycler of electronic equipment.
Recyclers will find the products easy to dismantle into their major component parts for efficient
recycling. Many parts snap together and can be separated without the use of tools, whilst other
parts are secured with conventional fasteners. 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' packaging strategy prefers 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.
Software Statement
This Solutions Module (SM) is supplied with the latest software version. When retro-fitting to an
existing system, all software versions should be verified to confirm the same functionality as
Solutions Modules of the same type already present. This also applies to products returned from
LEROY-SOMER. If there is any doubt please contact the supplier of the product.
The software version of the Solutions Module can be identified by looking at Pr MM.02 and Pr
MM.51, where MM is the relevant menu number for the Solutions Module slot being used.
See Pr MM.02 and Pr MM.51 description later in this manual for more information.
The software version takes the form of xx.yy.zz, where Pr MM.02 displays xx.yy and Pr MM.51
displays zz (e.g. for software version 01.01.00 Pr MM.02 will display 1.01 and Pr MM.51 will
display 0).
REACH legislation
EC Regulation 1907/2006 on the Registration, Evaluation, Authorisation and restriction of
Chemicals (REACH) requires the supplier of an article to inform the recipient if it contains more
than a specified proportion of any substance which is considered by the European Chemicals
Agency (ECHA) to be a Substance of Very High Concern (SVHC) and is therefore listed by them
as a candidate for compulsory authorisation.
For current information on how this requirement applies in relation to specific LEROY-SOMER
products, please approach your usual contact in the first instance.

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 User Guide.
1.3 System design and safety of personnel
The drive is intended as a component for professional incorporation into complete
equipment or a 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.
Close attention is required to the electrical installation and the system design to avoid
hazards either in normal operation or in the event of equipment malfunction. 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 User Guide carefully.
None of the drive functions 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.
With the sole exception of the SAFE TORQUE OFF (SECURE DISABLE) function
on Unidrive SP and Digitax ST, none of the drive functions must be used to
ensure safety of personnel, i.e. they must not be used for safety-related
functions.
The SAFE TORQUE OFF (SECURE DISABLE) function is only available on Unidrive
SP and Digitax ST. The Digidrive SK, Affinity and Mentor MP drives do not have either
of these features.
Careful consideration must be given to the functions of the drive which might result in a
hazard, either through their intended behavior 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, a fail-safe
mechanical brake in case of loss of motor braking.
A Warning contains information, which is essential for avoiding a safety hazard.
A Caution contains information, which is necessary for avoiding a risk of damage to the
product or other equipment.
A Note contains information, which helps to ensure correct operation of the product.

The SAFE TORQUE OFF (SECURE DISABLE) function meets the requirements of
EN954-1 category 3 for the prevention of unexpected starting of the drive, which allows
it to be used in a safety-related application. The system designer is responsible for
ensuring that the complete system is safe and designed correctly according to
the relevant safety standards.
1.4 Environmental limits
Instructions regarding transport, storage, installation and use of the drive must be
complied with, including the specified environmental limits. These instructions can be
found in the relevant drive documentation. Drives must not be subjected to excessive
physical force.
1.5 Compliance with 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 or other protection, and protective earth (ground)
connections.
Instructions for achieving compliance with specific EMC standards may be found in the
relevant drive documentation.
Within the European Union, all machinery in which this product is used must comply
with the following directives:
98/37/EC: Safety of machinery.
2004/108/EC: Electromagnetic Compatibility.
1.6 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 the 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 forced 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 in the motor rated current parameter: This
affects the thermal protection of the motor.
1.7 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.

2 Introduction
2.1 What is PROFIBUS-DP?
PROFIBUS-DP (Decentralized Peripheral) is a networking system that falls into the
generic category of fieldbus. Fieldbuses are generally defined as industrial networking
systems that are intended to replace traditional wiring systems. Figure 2-1 shows the
traditional cabling requirements to transfer signals between 2 slaves and a master.
Figure 2-1 Traditional cable layout
Table 2.1 details how the wiring is used to communicate data between the master and
the slaves. Each signal that is communicated requires one signal wire giving a total of
66 signal wires plus a 0V return.
A fieldbus topology such as PROFIBUS-DP allows the same configuration to be
realized using only two signal wires plus a shield. This method of communication saves
significantly on the amount of cabling required and can improve overall system reliability
as the number of interconnections is greatly reduced.

Figure 2-2 shows a typical PROFIBUS-DP network system transferring the same
signals as given in the traditionally wired example. The signals are now transmitted by
converting them into a serial data stream which is received by the master as if they were
connected using traditional wiring. The data stream on SM-PROFIBUS DP-V1 allows up
to 64 (32 input and 32 output) independent values to be sent or received by the master,
in addition to a single channel allowing for random access to drive parameters.
Figure 2-2 PROFIBUS DP cable layout
Table 2.2 Data mappings for SM-PROFIBUS DP-V1
Table 2.2 details the number of data words used to communicate the signals using the
PROFIBUS-DP network. It can be seen that the resulting reduction in cabling is
significant.
PROFIBUS-DP can transfer data using two distinct modes. The first of these modes is
cyclic where signals are sent in predefined blocks at regular intervals. This is the
equivalent of the hard-wired example in Figure 2-1.

The second method of transfer is called non-cyclic data and is used for sending values
that only need to be changed occasionally or where the source or destination of the
signal changes. This is the equivalent of a temporary patch lead that is removed after
use.
2.2 What is SM-PROFIBUS DP-V1?

Figure 2-4 SM-PROFIBUS DP-V1 labels
2.4.1 Date code format
The date code is split into two sections: a letter followed by a number.
The letter indicates the year, and the number indicates the week number (within the
year) in which the Solutions Module was built.
The letters go in alphabetical order, starting with A in 1991 (B in 1992, C in 1993 etc.).
Example:
A date code of R15 would correspond to week 15 of year 2008.
2.4.2 Unidrive SP: Backup / Auxiliary Supply
The Unidrive SP can be connected to a back-up power supply. This keeps the control
electronics and Solutions Module powered up, allowing the SM-PROFIBUS DP-V1 to
continue communicating with the PROFIBUS DP-V1 master controller when the main
supply to the Unidrive SP is switched off. For every SM-PROFIBUS DP-V1 fitted allow
for an extra 70mA of supply current to be drawn from the backup supply.

4.1 Terminal descriptions
The SM-PROFIBUS DP-V1 has a standard 9-way female D-type connector for the
PROFIBUS-DP network.
Figure 4-1 SM-PROFIBUS DP-V1 terminals
Figure 4-2 SM-PROFIBUS DP-V1 D-Type pin out
LEROY-SOMER recommend using connectors approved by Profibus International at all
times.
4.2 PROFIBUS-DP connectors
There are many manufacturers of PROFIBUS-DP connectors. Always ensure that any
connectors used on the network are fully approved for use with PROFIBUS-DP. Some
of the connector types available include built in termination that allows the network to be
isolated, this can be very useful when fault finding. For data rates above 1.5Mbs
connectors fitted with integrated inductors should be used.

4.3 PROFIBUS-DP cable
PROFIBUS-DP networks can run at high data rates and require cable specifically
designed to carry high frequency signals. Low quality cable will attenuate the signals,
and may render the signal unreadable for the other nodes on the network. Cable
specifications and a list of approved manufacturers of cable for use on PROFIBUS-DP
networks are available on the PROFIBUS Nutzerorganization (PNO) web site at
www.profibus.com.
4.4 Cable shielding
Correct shielding of the PROFIBUS-DP cable is required for reliable operation at high
data rates, this can be achieved by exposing the cable shield of each PROFIBUS-DP
cable and ensuring that they are clamped to the drive grounding metalwork as close as
possible to the drive termination, contact LEROY-SOMER for more information.
4.5 General grounding considerations
It is essential that good grounding is provided not only for network stability but more
importantly electrical safety. In all instances electrical regulations should be adhered to.
As a guide the network cable should be grounded at least once per cabinet, ideally on
each drive.
4.6 Network termination
It is very important in high-speed communications networks that the network
communications cable is fitted with the specified termination resistor network at each
end of each segment. This prevents signals from being reflected back down the cable
and causing interference.
Most ranges of connectors provide specific parts that incorporate the termination
network. Such connectors derive the power from the host device and if the host device
is switched off the termination will be lost. To avoid this situation a separate termination
device is available that is powered independently of the network devices. For more
information go to www.profibus.com.
LEROY-SOMER can only guarantee correct and reliable operation of the SM-
PROFIBUS DP-V1 if all other equipment on the PROFIBUS-DP network (including the
network cable) has been approved by the PNO and is correctly installed.
NOTE
Unless there are specific reasons for not grounding the network it is recommended that
all drive network connections are correctly grounded. Failure to do so may reduce the
noise immunity of the system. If there are specific issues with grounding, alternative
methods of connection should be considered such as the use of fibre optic cable.
NOTE
Failure to terminate a network correctly can seriously affect the operation of the network.
If the correct termination networks are not fitted, the noise immunity of the network is
greatly reduced. Each network segment must be correctly terminated.

4.7 Maximum network length / device loading
The maximum number of devices that can be connected to a single PROFIBUS-DP
network segment is 32, this includes all nodes and any repeaters. The maximum
lengths of cable for a segment depend on the data rate and are shown in Table 4.2.
Repeaters or fiber optic segments can be used to extend the network, allowing more
than 32 nodes to be connected on the network. The maximum number of nodes on a
single network is 125.
4.8 Node addressing
SM-PROFIBUS DP-V1 has a valid address range of 1 to 125. Addresses 126 and 0 are
reserved for system use and should not be used. The addressing scheme used is at the
discretion of the end user however it is recommended that nodes are numbered in order
as they appear on the physical network. It is not necessary to use consecutive numbers
and gaps in the addressing scheme may be left to allow for future expansion.
4.9 Spurs
The PROFIBUS-DP specification allows spurs at data rates less than 1.5Mbits/s. At
data rates below 1.5Mbits/s there are specific requirements for capacitance and length
of cable allowed when using spurs. LEROY-SOMER recommend that spurs are not
used as extreme care is required at the design stage to avoid network problems. More
information on spurs can be found on the PROFIBUS web site at www.profibus.com.
4.10 Minimum node to node cable length
The minimum recommended node to node distance is one metre of network cable.
This distance is necessary to avoid multiple nodes generating a single large reflection
on the network, using less than one metre of cable between nodes can have serious
implications for network reliability.
For full details on designing and installing a PROFIBUS-DP network, refer to Installation
Guidelines for PROFIBUS-DP/FMS. This document is available from the PROFIBUS
web site at www.profibus.com.

5 Getting started
This section is intended to provide a generic guide for setting up SM-PROFIBUS DP-V1
and a master controller. Figure 5-1 is intended as a guide only and is provided to detail
the stages that are required to achieve a functioning network. It is recommended that all
of this chapter is read, before attempting to configure a system.
5.1 Conventions used in this guide
The configuration of the host drive and Solutions Module is done using menus and
parameters. A menu is a logical collection of parameters that have similar functionality.
In the case of a Solutions Module, the parameters will appear in menu 15 for the
Digidrive SK, and in menu 15, 16, or 17 for the Unidrive SP, Affinity, Mentor MP and
Digitax ST depending on the slot the module is fitted in to.
The menu is determined by the number before the decimal point and the parameter by
the number following the decimal point.
The method used to determine the menu or parameter is as follows:
•PrMM.xx - Menu corresponding to the Solution Module and any parameter.
•Prxx.00 - signifies parameter number 00 in any menu.
5.2 Minimum software versions required
Due to the large number of PLCs/masters that support PROFIBUS-DP only generic
details can be provided. Support is available through your supplier or LEROY-SOMER.
Before contacting your supplier or LEROY-SOMER for support ensure you have read
Chapter 10 on page 53 of this manual and check you have configured all parameters
correctly.
Ensure the following information is available before calling:
• A list of all parameters in SM-PROFIBUS DP-V1.
• The drive firmware version (see the relevant drive user guide).
• The SM-Profibus DP-V1 firmware version.

5.4 Node address
Every node on a PROFIBUS-DP network must be given a unique network node
address. To activate a change in the node address value the SM-PROFIBUS DP-V1
must be re-initialized (Pr MM.32 = ON). This parameter is also available in menu 0 on
the Digidrive SK (Pr 00.52). Addresses 0 and 126 are reserved for system use.
5.5 Network data rate
The SM-PROFIBUS DP-V1 will automatically detect the PROFIBUS-DP network data
rate and synchronize to it. Pr MM.04 will indicate the data rate that has been detected
by the SM-PROFIBUS DP-V1. This parameter is also available in menu 0 on the
Digidrive SK (Pr 00.53).
A value of -1 indicates that the SM-PROFIBUS DP-V1 has not detected any activity on
the PROFIBUS-DP network, and is waiting for the master controller to start
communicating.

5.6 Data format
The default data format is four cyclic words, each cyclic data channel is mapped to a
drive parameter. The default mappings are shown in Table 5.6.
Other data formats are also supported. For further details see section 7.2 Data
formats on page 24. The directions specified in Table 5.6 relate to the data direction as
seen by the master.
5.7 Network operating status
The PROFIBUS-DP network activity can be monitored in the SM-PROFIBUS DP-V1
operating status parameter, Pr MM.06. When the SM-PROFIBUS DP-V1 is
communicating successfully with the PROFIBUS-DP master controller, Pr MM.06 will
give an indication of the number of cyclic data messages that are being processed per
second. This parameter is also available in menu 0 on the Digidrive SK (Pr 00.54).
If a mapping configuration error (see section 10.7 Mapping status ) or network error
(see section 10.9 Module error code ) is detected, the drive may trip.
Table 5.5 PROFIBUS-DP data format
Pr MM.05 Default 4 Ranges 0 to 32,100 to 131, 200 to 228
Access RW
The maximum number of 16-bit data words that is possible is 32 with only cyclic data, 31
with Mode 1 non-cyclic data and 28 with PPO4 word mode.

5.8 Re-initializing the SM-PROFIBUS DP-V1
Changes to the SM-PROFIBUS DP-V1 configuration in menu 15, 16 and 17 parameters
will not take effect until the SM-PROFIBUS DP-V1 has been re-initialized.
To re-initialize SM-PROFIBUS DP-V1:
•SetPrMM.32 to ON.
• When the sequence has been completed, Pr MM.32 will be reset to OFF.
• The SM-PROFIBUS DP-V1 will re-initialise using the updated configuration.
5.9 Re-initialize all Solutions Modules
To re-initialize all Solutions Modules fitted on a drive:
•SetPrxx.00 to 1070. (See note regarding Digidrive SK).
• Reset the drive.
5.10 Saving parameters to the drive
To avoid loss of the configured settings when the drive is powered down it is necessary
to write 1000 to Pr xx.00 followed by pressing the reset button to perform a drive save.
To store drive parameters:
•SetPrxx.00 to 1000. (See note regarding Digidrive SK).
• Reset the drive.
The drive will store all the drive parameters (except applications menu 20) but the
operation of the SM-PROFIBUS DP-V1 will not be affected. Any changes made to the
SM-PROFIBUS DP-V1 configuration parameters (mapping etc.) will not take effect until
the SM-PROFIBUS DP-V1 module is reset.
