1 Safety information
1.1 Warnings, cautions and notes
1.2 Important safety information. Hazards. Competence of
designers and installers
This guide applies to products which control electric motors either directly (drives) or
indirectly (controllers, option modules and other auxiliary equipment and accessories).
In all cases the hazards associated with powerful electrical drives are present, and all
safety information relating to drives and associated equipment must be observed.
Specific warnings are given at the relevant places in this guide.
Drives and controllers are intended as components for professional incorporation into
complete systems. If installed incorrectly they 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/
start-up and maintenance must be carried out by personnel who have the necessary
training and competence. They must read this safety information and this guide
carefully.
1.3 Responsibility
It is the responsibility of the installer to ensure that the equipment is installed correctly
with regard to all instructions given in this guide. They must give due consideration to
the safety of the complete system, so as to avoid the risk of injury both in normal
operation and in the event of a fault or of reasonably foreseeable misuse.
The manufacturer accepts no liability for any consequences resulting from
inappropriate, negligent or incorrect installation of the equipment.
1.4 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 ground (earth)
connections.
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.
WARNING
CAUT IO N
NOTE

8SI-INTERBUS User Guide
Issue Number: 1
This guide contains instructions for achieving compliance with specific EMC standards.
All machinery to be supplied within the European Union in which this product is used
must comply with the following directives:
2006/42/EC Safety of machinery.
2014/30/EU: Electromagnetic Compatibility.
1.5 Electrical hazards
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. Hazardous voltage may be present in any of the following locations:
• AC and DC supply 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.
The supply must be disconnected by an approved electrical isolation device before
gaining access to the electrical connections.
The STOP and Safe Torque Off functions of the drive do not isolate dangerous voltages
from the output of the drive or from any external option unit.
The drive must be installed in accordance with the instructions given in this guide.
Failure to observe the instructions could result in a fire hazard.
1.6 Stored electrical 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 energized, the AC supply must
be isolated at least ten minutes before work may continue.
1.7 Mechanical hazards
Careful consideration must be given to the functions of the drive or controller which
might result in a hazard, either through their 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.
With the sole exception of the Safe Torque Off function, 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 function may 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.
The design of safety-related control systems must only be done by personnel with the
required training and experience. The Safe Torque Off function will only ensure the
safety of a machine if it is correctly incorporated into a complete safety system. The
system must be subject to a risk assessment to confirm that the residual risk of an
unsafe event is at an acceptable level for the application.

1.8 Access to equipment
Access must be restricted to authorized personnel only. Safety regulations which apply
at the place of use must be complied with.
1.9 Environmental limits
Instructions in this guide regarding transport, storage, installation and use of the
equipment must be complied with, including the specified environmental limits.
This includes temperature, humidity, contamination, shock and vibration. Drives must
not be subjected to excessive physical force.
1.10 Hazardous environments
The equipment must not be installed in a hazardous environment (i.e. a potentially
explosive environment).
1.11 Motor
The safety of the motor under variable speed conditions must be ensured.
To avoid the risk of physical injury, do not exceed the maximum specified speed of the
motor.
Low speeds may cause the motor to overheat because the cooling fan becomes less
effective, causing a fire hazard. The motor should be installed 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 must not be relied upon. It is essential that the correct
value is entered in the Motor Rated Current parameter.
1.12 Mechanical brake control
Any brake control functions are provided to allow well co-ordinated operation of an
external brake with the drive. While both hardware and software are designed to high
standards of quality and robustness, they are not intended for use as safety functions,
i.e. where a fault or failure would result in a risk of injury. In any application where the
incorrect operation of the brake release mechanism could result in injury, independent
protection devices of proven integrity must also be incorporated.
1.13 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.
1.14 Electromagnetic compatibility (EMC)
Installation instructions for a range of EMC environments are provided in the relevant
Power Installation Guide. If the installation is poorly designed or other equipment does
not comply with suitable standards for EMC, the product might cause or suffer from
disturbance due to electromagnetic interaction with other equipment. It is the
responsibility of the installer to ensure that the equipment or system into which the
product is incorporated complies with the relevant EMC legislation in the place of use.

2 Introduction
2.1 General
The SI-Interbus option module allows a Control Techniques drive to be connected to an
Interbus network and operate as an Interbus slave device. It will allow transfer of up to
10 x 16-bit cyclic input data and 10 x 16-bit cyclic output data between the local drive
(and its option modules), and external devices on the Interbus network.
The SI-Interbus module can be fitted to any one of the expansion slots in the
Unidrive M200 to M400, Unidrive M600/M7XX, Digitax HD or Commander C200/C300.
2.2 Identification
The SI-Interbus option module can be identified by:
• The label located on the top of the option module (Table 2-1 SI-Interbus top label
(500 kBd and 2 MBd))
• The colour of the front bezel (Grey)
Figure 2-1 SI-Interbus option module (2 MBd)
Table 2-1 shows sample module labels that would be fitted to the SI-Interbus modules

Two variants are available, 500 kBd and 2 MBd. The specific variant can be identified
from the label located on the top of the option module
2.2.1 Part numbers
The following table shows the available options for the SI-Interbus module.
Table 2-2 SI-Interbus option part numbers
2.3 Date code format
The module date code is a four digit number. The first two digits indicate the year and
the remaining two digits indicate the week of the year in which the option module was
manufactured.
Example:
A date code of 1914 would correspond to week 14 of the year 2019.
2.4 Terminology
2.4.1 Input / Output
Throughout this document, the terms IN (or Input) and OUT (or Output) when referring
to the cyclic data, refer to the data in relation to the Interbus master, so IN (or Input)
would refer to the data transmitted from the SI-Interbus to the Interbus master and OUT
(or Output) would refer to the data transmitted from the Interbus master to the
SI-Interbus module.
2.4.2 Parameter reference
The parameters within the SI-Interbus module use a 2-digit number reference for
the menu number and a 3-digit number reference for the parameter number.
However, some features (such as the cyclic mappings parameters) for compatibility
reasons only support a 2-digit number reference for the parameter, any 2-digit
parameter reference used in this document may also be used as a 3-digit number
reference by adding a leading 0.
So, for example, in Figure 6-1 Network loss trip detection, the setup parameters
15.07, 16.07 and 17.07 are used, these may be read as 15.007, 16.007 and 17.007
respectively.

Figure 5-4 Remote bus OUT wiring details
5.1 Interbus cable
Interbus cable has three twisted pairs plus overall shielding. The colours normally used
on Interbus networks are shown in Table 5-1 SI-Interbus connections. It is
recommended to follow these wiring guidelines as this will make it easier to trace
possible wiring errors during commissioning.
5.2 SI-Interbus cable shield connections
The Remote Bus IN and Remote Bus OUT cable shields MUST be connected to the
shell of the connector. There is no requirement to connect the cable shields directly to
Ground at any other point in the Interbus network.
5.3 Interbus network termination
Termination resistors are not required on Interbus networks, as each section of cable is
automatically terminated on every Interbus device. The Ground Tab of the SI-Interbus
must be connected to a suitable grounding point as close to the drive as possible using
the minimal cable length.
5.4 Maximum network length
The maximum cable length is 400 metres between Remote Bus devices. Hence, the
maximum total length of the Interbus network depends entirely on the number of
devices connected to the network.

6 Getting started
6.1 Node address
Interbus devices do not require a specific node address to be configured, the physical
wiring of the network determines the Communication Reference (CR) that will be
assigned to the device by the Interbus master controller.
6.2 Communication data rate
Interbus networks operate at a fixed baud rate, either 500 kBd or 2 MBd.
The SI-Interbus module is configured during manufacture to operate at one of these
rates, this configuration is determined by the part number specified at the time of
ordering and cannot be changed by the user.
6.3 Parameter reference
Parameters are referenced using the notation Pr MM.xx, where ‘Pr’ means parameter,
‘MM’ represents menu 15, 16 or 17 (depending upon which slot contains the option
module) and ‘xx’ is the parameter number within the menu.
Table 6-1 Slot / menu numbering
The following conventions are used in this document:
•PrMM.ppp – Where MM signifies the slot specific menu allocated to the option
module setup menu and ppp signifies the parameter number within that setup
menu.
•Prmm.000 – Signifies parameter number 0 in any drive or option menu.
The SI-Interbus module displays the module ID code in Pr MM.001, this module ID code
is used to identify the module variant.
6.4 Configuring the cyclic data
6.4.1 What is cyclic data
Cyclic data is a method of data transfer that must be setup during network configuration,
but is transmitted automatically once configuration is complete. The high speed data
transfer is achieved by transmitting only data bytes over the Interbus network, and
relying on local mapping information within the SI-Interbus and Interbus master
controller to ensure that the correct data is sent to the correct locations. This method
relies on the master controller program writing and reading data values to and from the
registers allocated to the node during network configuration, and the source and
destination of IN and OUT data being setup correctly in the drive.
