Safety Instructions
Instruction manual
Read the instruction manual first!
Handling the variable speed drive
Installation, commissioning, demounting, taking measure-
ments, etc, of or on the variable speed drive may only be car-
ried out by personnel technically qualified for the task. The
installation must be carried out in accordance with local
standards.
Opening the variable speed drive
WARNING: Always switch off the mains voltage
before opening the variable speed drive and wait
at least 5 minutes to allow the buffer capacitors
to discharge.
Always take adequate precautions before opening the varia-
ble speed drive. Although the connections for the control
signals and the switches are isolated from the main voltage,
do not touch the control board when the variable speed
drive is switched on.
Precautions to be taken with a
connected motor
If work must be carried out on a connected motor or on the
driven machine, the mains voltage must always be discon-
nected from the variable speed drive first. Wait at least 5
minutes before starting work.
Earthing
The variable speed drive must always be earthed via the
mains safety earth connection, indicated by “PE”.
Earth leakage current
This VSD has an earth leakage current which does exceeding
3.5 mA a.c. or 10 mA d.c. Therefore the minimum size of
the protective earth conductor must comply with the local
safety regulations for high leakage current equipment.
Residual current device (RCD)
compatibility
This product cause a d.c. current in the protective conduc-
tor. Where a residual current device (RCD) is used for pro-
tection in case of direct or indirect contact, only a Type B
RCD is allowed on the supply side of this product. Use
RCD of 300 mA minimum.
EMC Regulations
In order to comply with the EMC Directive, it is absolutely
necessary to follow the installation instructions. All installa-
tion descriptions in this manual follow the EMC Directive.
Mains voltage selection
The variable speed drive is suitable for use with the mains
voltage listed below. Adjustment of the mains voltage is not
necessary!
380-415 V
380-480 V
440-525 V
500-690 V
Voltage tests (Megger)
Do not carry out voltage tests (Megger) on the motor, before
all the motor cables have been disconnected from the varia-
ble speed drive.
Condensation
If the variable speed drive is moved from a cold (storage)
room to a room where it will be installed, condensation can
occur. This can result in sensitive components becoming
damp. Do not connect the mains voltage until all visible
dampness has evaporated.
Incorrect connection
The variable speed drive is not protected against incorrect
connection of the mains voltage, and in particular against
connection of the mains voltage to the motor outlets U, V
and W. The variable speed drive can be damaged in this way.
Power factor capacitors for improving
cosϕ
Remove all capacitors from the motor and the motor outlet.
Precautions during Autoreset
When the automatic reset is active, the motor will restart
automatically provided that the cause of the trip has been
removed. If necessary take the appropriate precautions.
Transport
To avoid damage, keep the variable speed drive in its original
packaging during transport. This packaging is specially
designed to absorb shocks during transport.

Emotron AB 01-3695-01r1a Introduction 5
1. Introduction
Emotron VFX is intended for controlling the speed and
torque of standard three phase asynchronous electrical
motors. The VSD is equipped with a sophisticated vector
control which uses built-in DSP, giving the inverter the
capability of high dynamic performance even at very low-
speeds without using feedback signals from the motor.
Therefore the inverter is designed for use in high dynamic
applications where low speed high torque and high-speed
accuracy are demanded. In “simpler” application such as fans
or pumps, the VFX vector control offers other great advan-
tages such as insensitivity to mains disturbances or load
shocks.
The following symbols can appear in this manual. Always
read these first before continuing:

3. Installation
The description of installation in this chapter complies with
the EMC standards and the Machine Directive.
Select cable type and screening according to the EMC
requirements valid for the environment where the VSD is
installed.
3.1 Before installation
Read the following checklist and think through your appli-
cation before installation.
• External or internal control.
• Long motor cables (>100m).
• Motors in parallel.
• Functions.
• Suitable VSD size in proportion to the motor/applica-
tion.
• Mount separately supplied option boards according to
the instructions in the appropriate option manual.
If the VSD is temporarily stored before being connected,
please check the technical data for environmental condi-
tions. If the VSD is moved from a cold storage room to the
room where it is to be installed, condensation can form on
it. Allow the VSD to become fully acclimatised and wait
until any visible condensation has evaporated before con-
necting the mains voltage.
3.2 Cable connections
3.2.1 Motor cables
To comply with the EMC emission standards the variable
speed drive is provided with a RFI mains filter. The motor
cables must also be screened and connected on both sides. In
this way a so-called “Faraday cage” is created around the
VSD, motor cables and motor. The RFI currents are now
fed back to their source (the IGBTs) so the system stays
within the emission levels.
Requirements for selecting motor
cables
• Use screened cables according to specification in table 7.
• Use heat-resistant cables, +60°C or higher.
• Dimension the cables and fuses in accordance with the
nominal output current of the motor. See table 41, page
152.
• Maximum length of the motor cable.
• The screening must be connected 360°and always at
both ends, to the motor housing and the VSD housing.
When painted mounting plates are used, do not be
afraid to scrape away the paint to obtain as large ca
ontact surface as possible at all mounting points for
items such as saddles and the bare cable screening. Rely-
ing just on the connection made by the screw thread is
not sufficient.
• The litz connection is only necessary if the mounting
plate is painted. All the variable speed drives have an
unpainted back side and are therefore suitable for
mounting on an unpainted mounting plate.
Connect the motor cables according to U - U, V - V and
W - W.
Fig. 14
Switches between the motor and the
VSD
If the motor cables are to be interrupted by maintenance
switches, output coils, etc., it is necessary that the screening
is continued by using metal housing, metal mounting plates,
etc. as shown in the Fig. 16.
Fig. 17 shows an example when there is no metal mounting
plate used (e.g. if IP54 variable speed drives are used). It is
important to keep the “circuit” closed, by using metal hous-
ing and cable glands.
NOTE: It is important that the motor housing has the
same earth potential as the other parts of the machine.

Pay special attention to the following points:
• If paint must be removed, steps must be taken to prevent
subsequent corrosion. Repaint after making connections!
• The fastening of the whole variable speed drive housing
must be electrically connected with the mounting plate
over an area which is as large as possible. For this purpose
the removal of paint is necessary. An alternative method
is to connect the variable speed drive housing to the
mounting plate with as short a length of litz wire as pos-
sible.
• Try to avoid interruptions in the screening wherever pos-
sible.
• If the variable speed drives of models 300 to 1k5 (IP54)
are mounted in a standard cabinet, the internal wiring
must comply with the EMC standard. Fig. 16 shows an
example of a large size VSD built into a cabinet.

Placing of motor cables
Keep the motor cables as far away from other cables as possi-
ble, especially from control signals. The minimum distance
between motor cables and control cables is 30 cm.
Avoid placing the motor cables in parallel with other cables.
The power cables should cross other cables at an angle of
90°.
Long motor cables
If the connection to the motor is longer than 100 m (40 m
for models 003-013), it is possible that capacitive current
peaks will cause tripping at overcurrent. Using output coils
can prevent this. Contact the supplier for appropriate coils.
Switching in motor cables
Switching in the motor connections is not advisable. In the
event that it cannot be avoided (e.g. emergency or mainte-
nance switches) only switch if the current is zero. If this is
not done, the VSD can trip as a result of current peaks.
3.2.2 Mains cables
Dimension the mains and motor cables according to local
regulations. The cable must be able to carry the VSD load
current.
Requirements for selecting mains
cables
• The mains cables do not need to be screened.
• Use heat-resistant cables, +60°C or higher.
• Dimension the cables and fuses in accordance with the
nominal output current of the motor. See table 41, page
152.
• The litz connection is only necessary if the mounting
plate is painted. All the variable speed drives have an
unpainted back side and are therefore suitable for
mounting on an unpainted mounting plate.
Connect the mains cables according to Fig. 18 The VSD has
a RFI mains filter that complies with the 2nd environment
standard.

3.6 Thermal protection on the
motor
Standard motors are normally fitted with an internal fan.
The cooling capacity of this built-in fan is dependent on the
frequency of the motor. At low frequency, the cooling capac-
ity will be insufficient for nominal loads. Please contact the
motor supplier for the cooling characteristics of the motor at
lower frequency.
Motor thermistors offer better thermal protection for the
motor. Depending on the type of motor thermistor fitted,
the optional PTC input may be used. The motor thermistor
gives a thermal protection independent of the speed of the
motor, thus of the speed of the motor fan. See the functions,
Motor I2t type [231] and Motor I2t current [232].
3.7 Motors in parallel
It is possible to have motors in parallel as long as the total
current does not exceed the nominal value of the VSD. The
following has to be taken into account when setting the
motor data:
WARNING: Depending on the cooling
characteristics of the motor, the application,
the speed and the load, it may be necessary
to use forced cooling on the motor.
