2 Introduction
2.1 Features
The SM-I/O 24V Protected is designed as an over voltage protected I/O Solution
Module.
The Solutions Module is able to withstand a +48V input voltage being applied to the
+24V Digital I/O terminals.
The SM-I/O 24V Protected can be used on the following products:
• Unidrive SP
• Commander SK
• Commander GP20
The SM-I/O 24V Protected increases the I/O capability of the drive by adding the
following to the existing I/O:
• 2 x Analogue current outputs
• 4 x Digital inputs/outputs*
• 3 x Digital inputs
• 2 x Relay (30Vdc contact rating)**
All connections from the Solutions Module to the drive are made via the drive connector.
Connections from external equipment to the relay, digital I/O and analogue outputs are
made via a 17-way pluggable screw connector.
On the Unidrive SP a total of three SM-I/O 24V Protected modules can be fitted at any
one time. On the Commander SK only one can be fitted, on the Commander GP20 two
can be fitted.
*Only three digital outputs are available with Commander SK.
**1 relay on Commander SK

2.2.1 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 1990 (B in 1991, C in 1992 etc.).
Example:
A date code of L35 would correspond to week 35 of year 2002.
2.3 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
Commander SK, and in menu 15, 16 or 17 for the Unidrive SP and 15, 16 on the
Commander GP20 depending on the slot the module is fitted into. The menu is
determined by the number before the decimal point.
The method used to determine the menu or parameter is as follows:
•Prxx.00 - signifies any menu and parameter number 00.
•Prx.XX - where xsignifies the menu allocated to the Solutions Module (this could
be 15, 16 or 17 on the Unidrive SP, 15 or 16 on Commander GP20 but will always
be 15 on the Commander SK) and XX signifies the parameter number.

2.4 Solutions Module I/O
2.5 Digital I/O
All digital I/O complies with IEC 61131-2, clause 3.3.1 type 1, (i.e. >2mA @ +15Vdc).
For type 2 input, the user will need to add extra load externally.
Three terminals are dedicated digital inputs (4 with Commander SK); the functionality of
these inputs is as follows:
• The logic state of the input is monitored by a RO parameter
• The logic state can be inverted
• The digital input can be programmed to any unprotected parameter. The destination
parameter value will always be either 0 or 1 depending on the state of the input.
Four terminals are programmable as either digital inputs or output terminals (3 with
Commander SK), the functionality of these terminals is as follows:
Input
• The logic state of each input is monitored by a RO parameter
• The logic state can be inverted
• The digital input can be programmed to any unprotected parameter. The destination
parameter value will always be either 0 or 1 depending on the state of the input
Output
• The logic state of each output is monitored by a RO parameter
• The logic state can be inverted
• The digital outputs can be sourced from any parameter.
In the case where an integer parameter is used as the source, the threshold of
the output switching between low and high states is 50% of the parameter’s
maximum.
E.g. Source parameter = Pr 18.11 (maximum = 32767)
50% of 32767 = 16383 (due to integer truncation)
Therefore, if Pr 18.11 ≥16383 the output will be high
if Pr 18.11 < 16383 the output will be low
• The digital outputs can only source current
Solution Module I/O only operates in positive logic mode.
All I/O and relays are user programmable for function and signal processing.
All new source and destination routing only changes to new set up locations when the
drive is reset.
By default, the digital inputs/outputs on the Solutions Module are configured to operate
as inputs, except Digital I/O 4 which is configured as an output (input only for
Commander SK).
The logic state of a digital input will operate even without a destination parameter
programmed.

• The four digital outputs of the Solutions Module (three digital outputs with
Commander SK) are able to source 40 mA to the total combination of output
channels (e.g. 4 x 10mA or 1 x 40mA). When the current drawn exceeds safe limits,
all the outputs will be disabled through hardware and trip the drive to alert the user
to the fault condition.
**A maximum of three digital outputs are available with Commander SK.
2.6 Analogue output
Two terminals have a dedicated analogue output with the following functions:
• The output can be used to convey the value of any valid source parameter to
external equipment*.
• The output operates in one of the following modes as set in Pr x.39 : 0-20, 20-0, 4-20
and 20-4.
• A scaling factor can be applied to the analogue output signal*
*Only available on analogue output 1 with Commander SK.
2.7 Relays
The relay can be used to convey the logic state of any parameter to external equipment.
The logic state is processed as follows:
• Any source parameter is assigned to relay.
• The logic state can be inverted.
• The software state of the coil is monitored by a parameter.

Introduction Installing the
Solutions Module Parameters Diagnostics Terminal specification Protection Index
3 Safety Information
3.1 Warnings, Cautions and Notes
3.2 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.
3.3 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.
The STOP and SECURE DISABLE functions of the drive 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.
With the sole exception of the SECURE DISABLE 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.
Note that the SECURE DISABLE function is only available as standard on the Unidrive
SP and Commander GP20. The Commander SK does not have a SECURE DISABLE
input.
Careful consideration must be given to the functions of the drive 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
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.

in case of loss of motor braking.
The SECURE DISABLE function and secure input meet the requirements of EN954-1
category 3 for the prevention of unexpected starting of the drive. They 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.
3.4 Environmental limits
Instructions in the Unidrive SP User Guide, Commander GP20 User Guide,
Commander SK Getting Started Guide, Commander SK Technical Data Guide
regarding transport, storage, installation and use of the drive must be complied with,
including the specified environmental limits. Drives must not be subjected to excessive
physical force.
3.5 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.
The Unidrive SP User Guide, Commander GP20 User Guide and Commander SK
Technical Data Guide contain 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.
3.6 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:
Pr 0.46 for Unidrive SP / Commander GP20 and Pr 06 in Commander SK. This affects
the thermal protection of the motor.
3.7 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.
