Drive firmware version
This product is supplied with the latest firmware version. If this drive is to be connected to an existing system or machine,
all drive firmware versions should be verified to confirm the same functionality as drives of the same model already
present. This may also apply to drives returned from a Control Techniques Service Centre or Repair Centre. If there is
any doubt please contact the supplier of the product.
The firmware version of the drive can be checked by looking at Firmware Version (J04).
Environmental statement
Control Techniques 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. Further information on the EMS, our Environmental Policy and other
relevant information is available on request, or can be found at www.greendrives.com.
The electronic variable-speed drives manufactured by Control Techniques 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, while 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 for wrapping product, can be recycled in the
same way. Control Techniques' 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.
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 Control Techniques products, please

Parameters
Diagnostics Optimization CT MODBUS RTU Technical Data
A Note contains information which helps to ensure correct operation of the product.
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 Design 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/start-up and maintenance must be carried out by personnel who have the necessary training
and experience. They must read this safety information and this Design Guide carefully.
The STOP and Safe Torque Off (STO) 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 Safe Torque Off (STO) 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.
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, 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.
The Safe Torque Off (STO) 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.
1.4 Environmental limits
Instructions in this Design 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.
1.5 Access
Drive access must be restricted to authorized personnel only. Safety regulations which apply at the place of use must be complied with.
1.6 Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided. For further information, refer to section 3.2.5 Fire
protection on page 29.
1.7 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.
This 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:
2006/42/EC: Safety of machinery.
2004/108/EC: Electromagnetic Compatibility.

1.8 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 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 should not be relied upon.
It is essential that the correct value is entered into the Motor Rated Current (B02). This affects the thermal protection of the motor.
1.9 Mechanical brake control
The brake control functions are provided to allow well coordinated 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.
1.10 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.
1.11 Electrical installation
1.11.1 Electric shock risk
The voltages present in the following locations can cause severe electric shock and may be lethal:
•AC supply cables and connections
•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.
1.11.2 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
energized, the AC supply must be isolated at least ten minutes before work may continue.

t protection defaults to be compatible with:
Motor I
N
If the application uses a self ventilated (TENV/TEFC) induction motor and increased thermal protection is required for speeds below 50 % base
speed, then this can be enabled by setting Low Speed Thermal Protection Mode (B44) = On (1).
The rating label details the available output current under the following conditions:
•40 °C (104 °F) maximum ambient,
•1000 m altitude,
•8 kHz switching frequency,
•A typical elevator profile (50 % ED),
•IGBT lifetime optimization enabled (reduction of switching frequency based on drive inverter temperature).
Derating is required for higher switching frequencies, ambient temperatures >40 °C (104 °F) and higher altitude. For derating information, refer to
section 2.4.2 Power and current ratings (derating for switching frequency and temperature) on page 14.
The input current is affected by the supply voltage and impedance. The input current given on the rating label is the typical input current and is stated
for a balanced supply.
Fuses
The AC supply to the drive must be installed with suitable protection against overload and short-circuits. The following section shows
recommended fuse ratings. Failure to observe this requirement will cause risk of fire.

2.4.1 Typical short term overload limits
The maximum overload limit changes depending on the selected motor. Variations in motor rated current, motor power factor and motor leakage
inductance all result in changes in the maximum possible overload due to the thermal models estimation of the motor temperature as a percentage of
its maximum allowed temperature. Typical values for overload are shown in the table below:

2.5 Operating modes
The E300 Advanced Elevator drive is designed to operate in any of the following modes, with the default operating mode being RFC-S.
Open loop mode
Open loop vector mode
Fixed V/F mode (V/Hz)
RFC - A, Closed loop vector
With position feedback sensor
Sensorless mode without position feedback for rescue operation
RFC - S, Closed loop Servo
With position feedback sensor
Sensorless mode without position feedback for rescue operation
2.5.1 Open loop mode
The drive applies power to the motor at frequencies varied by the user. The motor speed is a result of the output frequency of the drive and slip due
to the mechanical load. The drive can improve the speed control of the motor by applying slip compensation. The performance at low speed depends
on whether Fixed V/F mode or Open loop vector mode is selected.
Vector mode
The voltage applied to the motor is directly proportional to the frequency except at low speed where the drive uses motor parameters to apply the
correct voltage to keep the flux constant under varying load conditions. Typically 100 % torque is available down to 1 Hz for a 50 Hz motor.
Fixed V/F mode
The voltage applied to the motor is directly proportional to the frequency except at low speed where a voltage boost is provided which is set by the
user. This mode can be used for multi-motor applications. Typically 100 % torque is available down to 4 Hz for a 50 Hz motor.
2.5.2 RFC-A
Rotor Flux Control for Asynchronous induction motors RFC-A encompasses closed loop vector control with a position feedback device
With position feedback
For use with induction motors with a feedback device installed. The drive directly controls the speed of the motor using the feedback device to ensure
the rotor speed exactly as demanded. Motor flux is accurately controlled at all times to provide full torque all the way down to zero speed.
Sensorless mode without position feedback for rescue operation
Sensorless mode provides closed loop control without the need for position feedback by using current, voltages and key motor parameters to
estimate the motor speed.
2.5.3 RFC- S
Rotor Flux Control for Synchronous permanent magnet brushless motors RFC-S provides closed loop control with position feedback device.
With position feedback
For use with permanent magnet brushless motors with a feedback device installed. The drive directly controls the speed of the motor using the
feedback device to ensure the rotor speed is exactly as demanded. Flux control is not required because the motor is self excited by the permanent
magnets which form part of the rotor. Absolute position information is required from the feedback device to ensure the output voltage is accurately
matched to the back EMF of the motor. Full torque is available all the way down to zero speed.
Sensorless mode without position feedback for rescue operation
Sensorless mode provides closed loop control without the need for position feedback by using current, voltages and key motor parameters to
estimate the motor speed.

2.10 EMC filters
There are three EMC filter options available:
Table 2-12 EMC filter options
Filter optionRequirements of EN 61800-3:2004 met
Internal EMC filterSecond environment, with short motor cable
Standard external EMC filterFirst and second environment with motor cable length up to 100 m
Compact external EMC filterFirst and second environment with motor cable length up to 20 m
2.10.1 Internal EMC filter
It is recommended that the internal EMC filter be kept in place unless there is a specific reason for removing it, for example the drive is part of a
Regen system or there is excessive ground leakage current in the system.
The internal EMC filter reduces radio-frequency emission into the line power supply. Where the motor cable is short, it permits the requirements of EN
61800-3:2004 to be met for the second environment. For longer motor cables the filter continues to provide a useful reduction in emission levels, and
when used with any length of shielded motor 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 instructions given above require it to be removed, or where the ground
leakage current is unacceptable.
If the drive is used with ungrounded (IT) supplies, the internal EMC filter must be removed unless additional motor ground fault protection
is installed.
The power supply must be removed prior to removing the internal EMC filter.
2.10.2 Standard external EMC filter
The external EMC filter for all drive size can be either footprint or bookcase mounted, the details for each EMC filter is provided in the following.

When using the external Compact EMC filters an additional AC input line reactor is required which is selected to meet the requirements of EN 12015.
2.11 AC input line reactors
The AC power supply current harmonics for the complete Elevator system will be the vector sums of the harmonic currents for all of the individual
electrical loads in the system. Usually the main drive will dominate the electrical load, and it will be sufficient to ensure that these meet the harmonic
requirements detailed in IEC 61000-3-12 (EN 12015). Where drives are also used for ancillary functions such as door opening, ventilation etc., it may
be necessary to ensure that their harmonic contributions are not excessive, although generally their power ratings will be too small to be significant.
AC input line reactors must be provided in order to maintain the harmonics below the required levels detailed in IEC 61000-3-12 (EN 12015), the
following table provides details of suitable AC input line reactors to meet this standard whilst operating at rated power. Note the correct value reactor
depends upon the maximum input power for the particular Elevator system, and not necessarily the drive model / rating. For a given application, it is
important the actual maximum input power is measured / estimated and the correct reactor value calculated in inverse proportion to the power.
Where input line reactors are not required to meet IEC 61000-3-12 (EN 12015) line reactors may still be required due to power supply quality issues,
poor phase balance, severe disturbances etc in this case refer to section 4.11 Supplies requiring Input line reactors on page 90.

1. Radiated emission from the enclosure
This covers the frequency range 30 MHz to 1000 MHz.
The limits are the same as for the generic standard EN 61000-6-4 and are unchanged from the 1998 version.
2. Conducted emission from the AC mains port(s)
This covers the frequency range 0.15 MHz to 30 MHz.
The limits are the same as for the generic standard EN 61000-6-4 and are unchanged from the 1998 version.
3. Conducted emission from the power port(s) (motor port etc).
This covers the frequency range 0.15 MHz to 30 MHz.
These are new limits, which apply unless the motor cable length does not exceed 2 m or it is screened.
4. Impulse noise
This is a special requirement for impulsive conducted emission.
The limits are the same as for the 1998 version.
5. Voltage fluctuations
This covers fluctuations, which are variations in the supply voltage which result in lighting flicker.
These are new limits. They are based on the standard EN 61000-3-11.
6. Mains current harmonics
This covers harmonics up to order 40.
These are new limits. They are based on standard IEC 61000-3-4.
Conformity of the Control Techniques drive products with EN 12015
The drives conform to the standard for Power Drives Systems, EN 61800-3, and the generic standard for industrial environments EN 61000-6-4. In
many respects this also covers the requirements of EN 12015.
Mains conducted emission
Generally the standard optional external filter must be used.
The motor cable length is set by the filter capability, on the assumption that the highest available switching frequency is in use. If longer lengths are
required this can usually be achieved by reducing the switching frequency, see the appropriate EMC data sheet for further information.
Where the lift system has a rated input current exceeding 100 A, and a dedicated supply transformer, higher emission levels are permitted and then
only the built-in filter is required.
Please note that the standard test method requires the use of a mains supply cable 1 m long, this being the cable which connects the system under
test to the LISN (line impedance stabilization network). This requirement might be inconvenient and appear to be unrealistic in some cases. However
it is important to adhere to this recommendation to ensure a valid and comparable test result.
Output conducted emission
The cable must be screened and the screen must be correctly bonded in accordance with the EMC (Electromagnetic compatibility) section of this
Design Guide or the EMC data sheet for the product, unless the motor cable length is less than or equal to 2 m in length.
Impulse noise
The drive does not generate impulse noise. Care is required to ensure that associated power contactors do not generate impulse noise.
Voltage fluctuations
The drive does not in itself cause significant voltage fluctuations or flicker. The control system must be designed so as not to cause rapid changes in
motor power which could result in flicker. Generally the requirements for passenger comfort ensure that this is the case.
Mains current harmonics
The mains current harmonics for the complete lift system will be the vector sums of the harmonic currents for all of the individual electrical loads in the
system. Usually the main lift drive(s) will dominate the electrical load, and it will be sufficient to ensure that these meet the harmonic requirements.
Where electronic drives are also used for ancillary functions such as door opening, ventilation etc., it may be necessary to ensure that their harmonic
contributions are not excessive, although generally their power ratings will be too small to be significant. It is important that test conditions should be
realistic and/or calculations done correctly, in order for harmonic emission from small drives to be correctly assessed. Please see the note below on
test conditions for harmonic testing.
The information in section 2.11 AC input line reactors on page 23, shows the measures required for drives rated at 2.2 kW upwards, in order to meet
the harmonics requirements. For harmonic data related to the smaller drives which might be used for auxiliary functions, please refer to the relevant
EMC data sheet.
Input chokes must be provided in order to maintain the harmonics below the required levels. Table 2-15 gives the choke data. Note that the correct
value of choke depends upon the maximum input power for which the particular lift controller is designed, and not necessarily on the drive model
number or rating. The figure for input power in Table 2-15 is based on the efficiency of a typical standard Eff2induction motor. For a given application,
it is important that the actual maximum input power should be measured or estimated and the necessary choke value calculated in inverse proportion
to the power.

The limits in the table are based on the ratios of the specific harmonics to the rated fundamental current (In / I1 in clause 6.7.2 of EN 12015:2004).
2.13.2 Immunity - EN 12016
The standard gives immunity requirements over a range of standard immunity test methods. Generally these correspond to the tests required by the
generic standards for the residential and industrial environments, EN 61000-6-1 and EN 61000-6-2. However there are more severe test levels
prescribed for safety circuits. In the tests for safety circuits, the drive is permitted to trip but the safety function must continue to operate.
The following table shows the status of the whole range of drives covered by this data sheet.

3 Mechanical installation
This chapter describes how to use all mechanical details to install the drive. The drive is intended to be installed in an enclosure. Key features of this
chapter include:
•Installing the drive
•Option module installation
•Terminal location and torque settings
3.1 Safety information
Follow the instructions
The mechanical and electrical installation instructions must be adhered to. Any questions or doubt should be referred to the supplier of the
equipment. It is the responsibility of the owner or user to ensure that the installation of the drive and any external option unit, and the way
in which they are operated and maintained, comply with the requirements of the Health and Safety at Work Act in the United Kingdom or
applicable legislation and regulations and codes of practice in the country in which the equipment is used.
Competence of the installer
The drive must be installed by professional assemblers who are familiar with the requirements for safety and EMC. The assembler is
responsible for ensuring that the end product or system complies with all the relevant laws in the country where it is to be used.
Enclosure
The drive is intended to be mounted in an enclosure which prevents access except by trained and authorized personnel, and which
prevents the ingress of contamination. It is designed for use in an environment classified as pollution degree 2 in accordance with IEC
60664-1. This means that only dry, non-conducting contamination is acceptable.
3.2 Installation
The following considerations must be made for the installation:
3.2.1 Access
Access must be restricted to authorized 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 dependent. For further information refer to section 3.8 Enclosing standard drive for high
environmental protection on page 43
3.2.2 Environmental protection
The drive must be protected from:
•Moisture, including dripping water or spraying water and condensation. An anti-condensation heater may be required, which must be switched Off
when the drive is running.
•Contamination with electrically conductive material
•Contamination with any form of dust which may restrict the fan, or impair airflow over various components
•Temperature beyond the specified operating and storage ranges
•Corrosive gasses
During installation it is recommended that the vents on the drive are covered to prevent debris (e.g. wire off-cuts) from entering the drive.
3.2.3 Cooling
The heat produced by the drive must be removed without its specified operating temperature being exceeded. Note that a sealed enclosure gives
much reduced cooling compared with a ventilated one, and may need to be larger and/or use internal air circulating fans.
3.2.4 Electrical safety
The installation must be safe under normal and fault conditions.
3.2.5 Fire protection
The drive enclosure is not classified as a fire enclosure. A separate fire enclosure must be provided which can be metal and/or polymeric. Polymer
must meet requirements which can be summarized for larger enclosures as using materials meeting at least UL 94 class 5VB at the point of minimum
thickness. Air filter assemblies to be at least class V-2.
3.2.6 Electromagnetic compatibility
Variable speed drives are powerful electronic circuits which can cause electromagnetic interference if not installed correctly, with careful attention to
the layout of the wiring. Some simple routine precautions can prevent disturbance to typical industrial control equipment.
If it is necessary to meet strict emission limits, or if it is known that electromagnetically sensitive equipment is located nearby, then full precautions
must be observed. In-built into the drive, is an internal EMC filter, which reduces emissions under certain conditions. If these conditions are exceeded,
then the use of an external EMC filter (located very close to the drives input) may be required.
3.2.7 Hazardous areas
The drive must not be located in a classified hazardous area unless it is installed in an approved enclosure and the installation is certified.

3.3 Terminal cover removal
Isolation device
The AC and / or DC power 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.
Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the AC and / or DC power supply has been
disconnected. If the drive has been energized, the power supply must be isolated for 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 Control
Techniques or their authorized distributor.
