WARNINGS AND CAUTIONS
Instruction manual
Read throuhfully this instruction manual before using the Variable Speed Drive, VSD
Mains voltage selection
The variable speed drive may be ordered for use with the mains voltage range listed below.
SX-V-4: 230-480 V
SX-V-6: 500-690 V
IT Mains supply
The variable speed drives can be modified for an IT mains supply, (non-earthed neutral),
check manual and contract your supplier in case of doubt.
EMC Regulations
In order to comply with the EMC Directive, it is absolutely necessary to follow the installation
instructions. All installation descriptions in this manual follow the EMC Directive.
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.
Handling the inverter
Installation, commissioning, dismounting, taking measurements, etc, of or on the variable
speed drive may only be carried out by personnel technically qualified for the task. The
installation must be carried out in accordance with local standards.
Omron SX inverter manual
1
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.
Grounding the inverter
Be sure to ground the unit. Not doing so may result in a serious injury due to an electric
shock or fire.
Power factor capacitors for improving cos
Remove all capacitors from the motor and the motor outlet.
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.
Stop motion mechanical device to ensure safety
The inverter controls the motor electrically, but has no means to stop it mechanically under
some types of failures... In applications where mechanical stop is required to a degree of
safety, a safety assurance study should be carried out to determine the need of additional
mechanical braking devices.
Braking resistor and regenerative braking units
In case the application needs it, be sure to use a specified type of braking resistor/regenerative braking unit. In case of a braking resistor, install a thermal relay that monitors the temperature of the resistor. Not doing so might result in a burn due to the heat generated in the
braking resistor/regenerative braking unit. Configure a sequence that enables the Inverter
power to turn off when unusual overheating is detected in the braking resistor/regenerative
braking unit.
Electric protection of installation
Take safety precautions such as setting up a molded-case circuit breaker (MCCB) or fuses
that matches the Inverter capacity on the power supply side. Not doing so might result in
damage to property due to the short circuit of the load.
Wiring works and servicing the inverter
Wiring work must be carried out only by qualified personnel. Not doing so may result in a
serious injury due to an electric shock. Do not dismantle, repair or modify this product if
you’re not authorised and qualified for it. Doing so may result in an injury.
DC-link residual voltage
After switching off the mains supply, dangerous voltage can still be present in the VSD.
When opening the VSD for installing and/or commissioning activities wait at least 10 minutes. In case of malfunction a qualified technician should check the DC-link or wait for one
hour before dismantling the VSD for repair.
Opening the variable speed drive cover
Only qualified technician can open the inverter. Always take adequate precautions before
opening the inverter. 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.
Do not manipulate inverter under power
Do not change wiring , put on or take off optional devices or replace cooling fans while the
input power is being supplied. Doing so may result in a serious injury due to an electric
shock. Inspection of the Inverter must be conducted after the power supply has been
turned off. Not doing so may result in a serious injury due to an electric shock. The main
power supply is not necessarily shut off even if the emergency shutoff function is activated.

Omron SX inverter manual
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 disconnected from the variable speed drive first. Wait at least 5 minutes
before starting work.
Short-circuits
The Inverter has high voltage parts inside which, if short-circuited, might cause damage to
itself or other property. Place covers on the openings or take other precautions to make sure
that no metal objects such as cutting bits or lead wire scraps go inside when installing and
wiring.
Earth leakage current
This variable speed drive has an earth leakage current which does exceed 3.5 mA AC.
Therefore the minimum size of the protective earth conductor must comply with the local
safety regulations for high leakage current equipment which means that according the
standard IEC61800-5-1 the protective earth connection must be assured by one of following conditions:
1. Use a protective conductor with a cable cross-section of at least 10 mm2 for copper (Cu)
or 16 mm2 for aluminium (Al).
2. Use an additional PE wire, with the same cable cross-section as the used original PE and
mains supply wiring.
Residual current device (RCD) compatibility
This product cause a DC current in the protective conductor. Where a residual current
device (RCD) is used for protection 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.
Voltage tests (Megger)
Do not carry out voltage tests (Megger) on the motor, before all the motor cables have been
disconnected from the variable speed drive.
Precautions during Autoreset
When the automatic reset is active, the motor may restart automatically provided that the
cause of the trip has been removed. If necessary take the appropriate precautions.
Heat warning
Be aware of specific parts on the VSD having high temperature. Do not touch the Inverter fins,
braking resistors and the motor, which may become too hot during the power supply and for some
time after the power shut-off. Doing so may result in a burn.
Do not Operate the inverter with wet hands
Do not operate the Digital Operator or switches with wet hands. Doing so may result in a
serious injury due to an electric shock.

Mounting
Models 4090 to 4132 and 6090 to 6250
This chapter describes how to mount the VSD.
Before mounting it is recommended that the installation is planned out first.
Load: 56 to 74 kg
• Be sure that the VSD suits the mounting location.
• The mounting site must support the weight of the
VSD.
• Will the VSD continuously withstand vibrations
and/or shocks?
• Consider using a vibration damper.
• Check ambient conditions, ratings, required cooling air flow, compatibility of the motor, etc.
• Know how the VSD will be lifted and transported.
2.1
Lifting instructions
Note: To prevent personal risks and any damage to the
unit during lifting, it is advised that the lifting methods
described below are used.

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
Connect the mains cables according to the next figures. The VSD has as standard a built-in RFI mains filter that complies with category C3 which suits the
Second Environment standard.

• Suitable VSD size in proportion to the motor/application.
WARNING: The Brake Resistor must be
connected between terminals DC+ and R.
• 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 conditions. 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 connecting the
mains voltage.

3.2.2
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.
Dimension the mains and motor cables according to
local regulations. The cable must be able to carry the
VSD load current.
Recommendations for selecting motor
cables
Recommendations for selecting mains
cables
• Use screened cables according to specification in
table 7. Use symmetrical shielded cable; three
phase conductors and a concentric or otherwise
symmetrically constructed PE conductor, and a
shield.
• To fulfil EMC purposes it is not necessary to use
screened mains cables.
• When the conductivity of the cable PE conductor is
<50% of the conductivity of the phase conductor, a
separate PE conductor is required.
• Use heat-resistant cables, +60C or higher.
• Dimension the cables and fuses in accordance
with local regulations and the nominal current of
the motor. See table 42, page 174.
• Use heat-resistant cables, +60C or higher.
• The litz ground connection see fig. 15, 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.
Omron SX inverter manual
• Dimension the cables and fuses in accordance
with the nominal output current of the motor. See
table 42, page 174.
• Keep the motor cable between VSD and motor as
short as possible.
Installation
17
• The screening must be connected with a large
contact surface of preferable 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 contact surface as possible at all mounting
points for items such as saddles and the bare
cable screening. Relying just on the connection
made by the screw thread is not sufficient.
NOTE: It is important that the motor housing has the
same earth potential as the other parts of the machine.
• The litz ground connection, see fig. 16, 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.
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 possible.
• Try to avoid interruptions in the screening wherever
possible.
• If the variable speed drive is mounted in a standard
cabinet, the internal wiring must comply with the
EMC standard. Fig. 15 shows an example of a
VSD built into a cabinet.
Connect the motor cables according to U - U, V - V
and W - W.

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 capacity will be insufficient for nominal
loads. Please contact the motor supplier for the cooling characteristics of the motor at lower frequency.
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.
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:

The motors in parallel must have the

Connecting the Control
Signals
Cables
The standard control signal connections are suitable
for stranded flexible wire up to 1.5 mm2 and for solid
wire up to 2.5 mm2.
.
5.5.2
Types of control signals
Always make a distinction between the different types
of signals. Because the different types of signals can
adversely affect each other, use a separate cable for
each type. This is often more practical because, for
example, the cable from a pressure sensor may be
connected directly to the variable speed drive.
We can distinguish between the following types of
control signals:
Analogue inputs
Voltage or current signals, (0-10 V, 0/4-20 mA) normally used as control signals for speed, torque and
PID feedback signals.
Analogue outputs
Voltage or current signals, (0-10 V, 0/4-20 mA) which
change slowly or only occasionally in value. In general,
these are control or measurement signals.
Digital
Voltage or current signals (0-10 V, 0-24 V, 0/4-20 mA)
which can have only two values (high or low) and only
occasionally change in value.
Data
Usually voltage signals (0-5 V, 0-10 V) which change
rapidly and at a high frequency, generally data signals
such as RS232, RS485, Profibus, etc.
Relay
Relay contacts (0-250 VAC) can switch highly inductive loads (auxiliary relay, lamp, valve, brake, etc.).

Example:
The relay output from a variable speed drive which
controls an auxiliary relay can, at the moment of
switching, form a source of interference (emission) for
a measurement signal from, for example, a pressure
sensor. Therefore it is advised to separate wiring and
screening to reduce disturbances.
Fig. 25 Connecting the control signals SX-D4090
NOTE: The screening of control signal cables is
necessary to comply with the immunity levels given in
the EMC Directive (it reduces the noise level).
NOTE: Control cables must be separated from motor and
mains cables.
5.5.3
Screening
For all signal cables the best results are obtained if the
screening is connected to both ends: the VSD side
and the at the source (e.g. PLC, or computer). See
Fig. 26.
It is strongly recommended that the signal cables be
allowed to cross mains and motor cables at a 90
30
Control Connections

angle. Do not let the signal cable go in parallel with the
mains and motor cable.
5.5.4
Single-ended or double-ended
connection?
In principle, the same measures applied to motor
cables must be applied to all control signal cables, in
accordance with the EMC-Directives.
For all signal cables as mentioned in section 5.5.2 the
best results are obtained if the screening is connected
to both ends. See Fig. 26.
NOTE: Each installation must be examined carefully
before applying the proper EMC measurements.

5.5.5
Current signals ((0)4-20 mA)
A current signal like (0)4-20 mA is less sensitive to disturbances than a 0-10 V signal, because it is connected to an input which has a lower impedance (250
) than a voltage signal (20 k). It is therefore strongly
advised to use current control signals if the cables are
longer than a few metres.
5.5.6
Twisted cables
Analogue and digital signals are less sensitive to interference if the cables carrying them are “twisted”. This
is certainly to be recommended if screening cannot be
used. By twisting the wires the exposed areas are
minimised. This means that in the current circuit for
any possible High Frequency (HF) interference fields,
no voltage can be induced. For a PLC it is therefore
important that the return wire remains in proximity to
the signal wire. It is important that the pair of wires is
fully twisted over 360°.
5.6
Connecting options
The option cards are connected by the optional connectors X4 or X5 on the control board see Fig. 23,
page 27 and mounted above the control board. The
inputs and outputs of the option cards are connected
in the same way as other control signals.

Parameter sets
Parameter sets are used if an application requires different settings for different modes. For example, a
machine can be used for producing different products
and thus requires two or more maximum speeds and
acceleration/deceleration times. With the four parameter sets different control options can be configured
with respect to quickly changing the behaviour of the
VSD. It is possible to adapt the VSD online to altered
machine behaviour. This is based on the fact that at
any desired moment any one of the four parameter
sets can be activated during Run or Stop, via the digital inputs or the control panel and menu [241].

Each parameter set can be selected externally via a
digital input. Parameter sets can be changed during
operation and stored in the control panel.
NOTE: The only data not included in the parameter set is
Motor data 1-4, (entered separately), language,
communication settings, selected set, local remote, and
keyboard locked.
Define parameter sets
When using parameter sets you first decide how to
select different parameter sets. The parameter sets
can be selected via the control panel, via digital inputs
or via serial communication. All digital inputs and virtual inputs can be configured to select parameter set.
The function of the digital inputs is defined in the menu
[520].
Fig. 27 shows the way the parameter sets are activated via any digital input configured to Set Ctrl 1 or
Set Ctrl 2.
Fig. 27 Selecting the parameter sets
Select and copy parameter set
The parameter set selection is done in menu [241],
Select Set. First select the main set in menu [241],
normally A. Adjust all settings for the application. Usually most parameters are common and therefore it
saves a lot of work by copying set A>B in menu [242].
When parameter set A is copied to set B you only
change the parameters in the set that need to be
changed. Repeat for C and D if used.
With menu [242], Copy Set, it is easy to copy the
complete contents of a single parameter set to
another parameter set. If, for example, the parameter
sets are selected via digital inputs, DigIn 3 is set to Set
Ctrl 1 in menu [523] and DigIn 4 is set to Set Ctrl 2 in
menu [524], they are activated as in Table 14.
Activate the parameter changes via digital input by
setting menu [241], Select Set to DigIn.

Examples
Bottling machine with 3 different products
Different parameter sets can be used to easily change
the setup of a VSD to adapt quickly to different application requirements. For example when
Use 3 parameter sets for 3 different Jog reference
speeds when the machine needs to be set up. The 4th
parameter set can be used for “normal” remote control when the machine is running at full production.
• a process needs optimized settings in different
stages of the process, to
- increase the process quality
- increase control accuracy
- lower maintenance costs
- increase operator safety
Manual - automatic control
If in an application something is filled up manually and
then the level is automatically controlled using PID regulation, this is solved using one parameter set for the
manual control and one for the automatic control.
With these settings a large number of options are
available. Some ideas are given here:
7.1.1
Multi frequency selection
Within a single parameter set the 7 preset references
can be selected via the digital inputs. In combination
with the parameter sets, 28 preset references can be
selected using all 4 digital inputs: DigIn1, 2 and 3 for
selecting preset reference within one parameter set
and DigIn 4 and DigIn 5 for selecting the parameter
sets.
One motor and one parameter
set
This is the most common application for pumps and
fans.
Once default motor M1 and parameter set A have
been selected:
1. Enter the settings for motor data.
2. Enter the settings for other parameters e.g. inputs
and outputs
7.1.2
One motor and two parameter
sets
This application is useful if you for example have a
machine running at two different speeds for different
products.
Once default motor M1 is selected:
1. Select parameter set A in menu [241].
2. Enter motor data in menu [220].
3. Enter the settings for other parameters e.g. inputs
and outputs.
4. If there are only minor differences between the settings in the parameter sets, you can copy parameter set A to parameter set B, menu [242].
5. Enter the settings for parameters e.g. inputs and
outputs.
Note: Do not change motor data in parameter set B.
7.1.3
Two motors and two
parameter sets
This is useful if you have a machine with two motors
that can not run at the same time, such as a cable
winding machine that lifts up the reel with one motor
and then turns the wheel with the other motor.
36
Main Features
Omron SX inverter manual
One motor must stop before changing to an other
motor.
1. Select parameter set A in menu [241].
2. Select motor M1 in menu [212].
3. Enter motor data and settings for other parameters
e.g. inputs and outputs.
4. Select parameter set B in menu [241].
5. Select M2 in menu [212].
6. Enter motor data and settings for other parameters
e.g. inputs and outputs.
7.1.4
Example
The VSD is able to select fixed speeds via the control
of digital inputs. This can be used for situations where
the required motor speed needs to be adapted to
fixed values, according to certain process conditions.
Up to 7 preset references can be set for each parameter set, which can be selected via all digital inputs that
are set to Preset Ctrl1, Preset Ctrl2 or Preset Ctrl3.
The amount digital inputs used that are set to Preset
Ctrl determines the number of Preset References
available; using 1 input gives 2 speeds, using 2 inputs
gives 4 speeds and using 3 inputs gives 8 speeds.
The use of four fixed speeds, at 50 / 100 / 300 / 800
rpm, requires the following settings:
• Set DigIn 5 as first selection input; set [525] to Preset Ctrl1.
• Set DigIn 6 as second selection input; set [526] to
Preset Ctrl2.
• Set menu [341], Min Speed to 50 rpm.
• Set menu [362], Preset Ref 1 to 100 rpm.
• Set menu [363], Preset Ref 2 to 300 rpm.
The motor is protected by an internal protection for
thermal overload. When this protection is activated,
the VSD should wait until the motor is cooled down
enough before resuming normal operation. When this
problem occurs three times in a short period of time,
external assistance is required.
• Insert maximum number of restarts; set menu [251]
to 3.
I2t
• Activate Motor
to be automatically reset; set
menu [25A] to 300 s.
• Set relay 1, menu [551] to AutoRst Trip; a signal will
be available when the maximum number of restarts
is reached and the VSD stays in fault condition.
• The reset input must be constantly activated.
Reference priority
The active speed reference signal can be programmed
from several sources and functions. The table below
shows the priority of the different functions with
regards to the speed reference.
Table 15 Reference priority
Preset
Reference
Motor Pot
With these settings, the VSD switched on and a RUN
command given, the speed will be:
• 50 rpm, when both DigIn 5 and DigIn 6 are low.
• 300 rpm, when DigIn 5 is low and DigIn 6 is high.
• 800 rpm, when both DigIn 5 and DigIn 6 are high.
7.2
Remote control functions
Operation of the Run/Stop/Enable/Reset functions
As default, all the run/stop/reset related commands
are programmed for remote operation via the inputs
on the terminal strip (terminals 1-22) on the control
board. With the function Run/Stp Ctrl [215] and Reset
Control [216], this can be selected for keyboard or
serial communication control.
NOTE: The examples in this paragraph do not cover all
possibilities. Only the most relevant combinations are
given. The starting point is always the default setting
(factory) of the VSD.

For several non-critical application-related failure conditions, it is possible to automatically generate a reset
command to overcome the fault condition. The selection can be made in menu [250]. In this menu the maximum number of automatically generated restarts
allowed can be set, see menu [251], after this the VSD
will stay in fault condition because external assistance
is required.

Fig. 28 Default setting Run/Reset commands
Fig. 29 Functionality of the Stop and Enable input
The inputs are default set for level-control. The rotation
is determined by the setting of the digital inputs.
Enable and Stop functions
Both functions can be used separately or simultaneously. The choice of which function is to be used
depends on the application and the control mode of
the inputs (Level/Edge [21A]).
NOTE: In Edge mode, at least one digital input must be
programmed to “stop”, because the Run commands are
otherwise only able to start the VSD.
Enable
Input must be active (HI) to allow any Run signal. If the
input is made LOW, the output of the VSD is immediately disabled and the motor will coast.
!
CAUTION: If the Enable function is not
programmed to a digital input, it is considered
to be active internally.
Reset and Autoreset operation
If the VSD is in Stop Mode due to a trip condition, the
VSD can be remotely reset by a pulse (“low” to “high”
transition) on the Reset input, default on DigIn 8.
Depending on the selected control method, a restart
takes place as follows:
Level-control
If the Run inputs remain in their position the VSD will
start immediately after the Reset command is given.
Edge-control
After the Reset command is given a new Run command must be applied to start the VSD again.
Autoreset is enabled if the Reset input is continuously
active. The Autoreset functions are programmed in
menu Autoreset [250].
NOTE: If the control commands are programmed for
Keyboard control or Com, Autoreset is not possible.
Run Inputs Level-controlled.
Stop
If the input is low then the VSD will stop according to
the selected stop mode set in menu [33B] Stop Mode.
Fig. 29 shows the function of the Enable and the Stop
input and the Stop Mode=Decel [33B].
The inputs are set as default for level-control. This
means that an input is activated by making the input
continuously “High”. This method is commonly used if,
for example, PLCs are used to operate the VSD.
To run the input must be high.
NOTE: Stop Mode=Coast [33B] will give the same
behaviour as the Enable input.
38
!
CAUTION: Level-controlled inputs DO NOT
comply with the Machine Directive, if the inputs
are directly used to start and stop the machine.
The examples given in this and the following paragraphs follow the input selection shown in Fig. 30.

Load Monitor and Process
Protection [400]
7.5.1 Load Monitor [410]
The monitor functions enable the VSD to be used as a
load monitor. Load monitors are used to protect
machines and processes against mechanical overload
and underload, such as a conveyer belt or screw conveyer jamming, belt failure on a fan or a pump dry running. The load is measured in the VSD by the
calculated motor shaft torque. There is an overload
alarm (Max Alarm and Max Pre-Alarm) and an underload alarm (Min Alarm and Min Pre-Alarm).
The Basic Monitor type uses fixed levels for overload
and underload (pre-)alarms over the whole speed
range. This function can be used in constant load
applications where the torque is not dependent on the
speed, e.g. conveyor belt, displacement pump, screw
pump, etc.
For applications with a torque that is dependent on the
speed, the Load Curve monitor type is preferred. By
measuring the actual load curve of the process, characteristically over the range of minimum speed to
maximum speed, an accurate protection at any speed
can be established.

The Pump Control function is used to control a
number of drives (pumps, fans, etc., with a maximum
of 3 additional drives per I/O-board connected) of
which one is always driven by the SX-V. Other names
for this kind of controllers are 'Cascade controller' or
'Hydrophore controller'.

Depending on the flow, pressure or temperature, additional pumps can be activated via the appropriate signals by the output relays of the SX-V and/or the I/O
Board. The system is developed in such a way that
one SX-V will be the master of the system.
Select relay on the control board or on an option
board. The relays are set to functions for controlling
pumps. In the pictures in this section, the relays are
named R:Function, e.g. R:SlavePump1, which means
a relay on the control board or on an option board set
to function SlavePump1.

This is the default setting of the Pump Control. The
SX-V controls the Master pump which is always running. The relay outputs start and stop the other pumps
P1 to P6, depending on flow/pressure. In this configuration a maximum of 7 pumps can be controlled, see

Alternating MASTER
With this function the Master pump is not fixed to the
SX-V all the time. After the VSD is powered up or
started again after a stop or sleep mode the Master
pump is selected via the relay set to function Master
Pump. section 7.6.7 on page 49 shows a detailed wiring diagram with 3 pumps. The purpose of this function is that all pumps are used equally, so the lifetime
of all pumps, including the Master pump, will be equalized. Maximum 6 pumps can be controlled with this
function.
Omron SX inverter manual
NOTE: The pumps MUST have all the same power.
Feedback 'Status' input
In this example the additional pumps are controlled by
an other kind of drive (e.g. soft starter, frequency
inverter, etc.). The digital inputs on the I/O Board can
be programmed as a "Error" input for each pump. If a
drive fails the digital input will monitor this and the
PUMP CONTROL option will not use that particular
drive anymore and automatically switch to another
drive. This means that the control continues without
using this (faulty) drive. This function can also be used
to manually stop a particular pump for maintenance
purposes, without shutting down the whole pump system. Of course the maximum flow/pressure is then
limited to the maximum pump power of the remaining
pumps.

Fail safe operation
operation can be obtained by using the NC contacts
of the pump control relays. These can be programmed
for each individual additional pump. In this example
pumps P5 and P6 will run at maximum power if the
inverter fails or is powered down.
Some pump systems must always have a minimum
flow or pressure level, even if the frequency inverter is
tripped or damaged. So at least 1 or 2 (or maybe all)
additional pumps must keep running after the inverter
is powered down or tripped. This kind of "safe" pump

Checklist And Tips
1. Main Functions
Start by choosing which of the two main functions to use:
- "Alternating MASTER" function
In this case the “Master” pump can be alternated, although this function needs slightly more complicated wiring than the
“Fixed MASTER” function described below. The I/O Board option is necessary.
- "Fixed MASTER" function:
One pump is always the master, only the additional pumps alternate.
Notice that there is a big difference in the wiring of the system between these main functions, so it not possible to switch
between these 2 functions later on. For further information see section 7.6.2, page 46.
2. Number of pumps/drives
If the system consists of 2 or 3 pumps the I/O Board option is not needed. However, this does mean that the following
functions are not then possible:
- "Alternating MASTER" function
- With isolated inputs
With the I/O Board option installed, the maximum number of pumps is:
- 6 pumps if "Alternating MASTER" function is selected. (see section 7.6.3 on page 46)
- 7 pumps if "Fixed MASTER" function is selected. (see section 7.6.2, page 46)
3. Pump size
- "Alternating MASTER" function:
The sizes of the pumps must be equal.
- "Fixed MASTER" function:
The pumps may have different power sizes, but the master pump (SX-V) must always have the greatest power.
4. Programming the Digital inputs
If the digital inputs are used, the digital input function must be set to Drive feedback.
5. Programming the Relay outputs
After the Pump controller is switched on in menu [391] the number of drives (pumps, fans, etc.) must be set in menu [392]
(Number of Drives). The relays themselves must be set to the function SlavePump1-6 and if Alternate master is used,
MasterPump1-6 as well.
6. Equal Pumps
If all pumps are equal in power size it is likely that the Upper band is much smaller than the Lower band, because the maximum pump discharge of the master pump is the same if the pump is connected to the mains (50Hz). This can give a very
narrow hysteresis causing an unstable control area in the flow/pressure. By setting the maximum frequency of the inverter
only slightly above 50Hz it means that the master pump has a slightly bigger pump discharge than the pump on the mains.
Of course caution is essential in order to prevent the master pump running at a higher frequency for a longer period of
time, which in turn prevents the master pump from overloading.
7. Minimum Speed
With pumps and fans it is normal to use a minimum speed, because at lower speed the discharge of the pump or fan will
be low until 30-50% of the nominal speed (depending on size, power, pump properties, etc.). When using a minimum
speed, a much smoother and better control range of the whole system will be achieved.

Category 2: Controlled STOP:
The variable speed drive complies with the following
standards:
EN(IEC)61800-3:2004 Adjustable speed electronic
power drive systems, part 3, EMC product standards:
Standard: category C3, for systems of rated supply
voltage< 1000 VAC, intended for use in the second
environment.
Optional: Category C2, for systems of rated supply
voltage <1.000 V, which is neither a plug in device nor
a movable device and, when used in the first environment, is intended to be installed and commissioned
only by experienced person with the necessary skills in
installing and/or commissioning variable speed drives
including their EMC aspects.
8.2
Stop categories and
emergency stop
Stopping while the supply voltage is still present. This
STOP can be implemented with each of the variable
speed drives STOP command.
WARNING: EN 60204-1 specifies that every
machine must be provided with a category 0
stop. If the application prevents this from
being implemented, this must be explicitly
stated. Furthermore, every machine must be provided
with an Emergency Stop function. This emergency stop
must ensure that the voltage at the machine contacts,
which could be dangerous, is removed as quickly as
possible, without resulting in any other danger. In such
an Emergency Stop situation, a category 0 or 1 stop may
be used. The choice will be decided on the basis of the
possible risks to the machine.
NOTE: With option Safe Stop, a stop according EN954-1
Category 3 can be achieved. See chapter 13.8 page 165
The following information is important if emergency
stop circuits are used or needed in the installation
where a variable speed drive is used. EN 60204-1
defines 3 stop categories:
Category 0: Uncontrolled STOP:
Stopping by switching off the supply voltage. A
mechanical stop must be activated. This STOP may
not be implemented with the help of a variable speed
drive or its input/output signals.
Category 1: Controlled STOP:
Stopping until the motor has come to rest, after which
the mains supply is switched off. This STOP may not
be implemented with the help of a variable speed drive
or its input/output signals.

The VSD can be delivered with a control panel or a
blank panel.
9.1
General
The control panel displays the status of the VSD and is
used to set all the parameters. It is also possible to
control the motor directly from the control panel. The
control panel can be built-in or located externally via
serial communication. The VSD can be ordered without the control panel. Instead of the control panel
there will be a blank panel.
NOTE: The VSD can run without the control panel being
connected. However the settings must be such that all
control signals are set for external use.

10. Serial communication
The VSD provides possibility for different types of serial
communication.
• Modbus RTU via RS232/485
• Fieldbuses as Profibus DP and DeviceNet
• Industrial Ethernet type Modbus/TCP
10.1 Modbus RTU
The VSD has an asynchronous serial communication
interface behind the control panel. The protocol used
for data exchange is based in the Modbus RTU protocol, originally developed by Modicon. the physical
connection is RS232. The VSD acts as a slave with
address 1 in a master-slave configuration. The communication is half-duplex. It has a standard no return
zero (NRZ) format.
Fig. 46 Mounting frame for the control panel
The baud rate is fixed to 9600.
Communication information for the different parameter
sets.
The character frame format (always 11 bits) has:
• one start bit
• eight data bits
• two stop bits
10.2 Parameter sets
The different parameter sets in the VSD have the following DeviceNet instance numbers and Profibus slot/
index numbers:
Parameter Modbus/DeviceNet
set
Instance number
• no parity
It is possible to temporarily connect a personal computer with for example the software EmoSoftCom
(programming and monitoring software) to the RS232
connector on the control panel. This can be useful
when copying parameters between variable speed
drives etc. For permanent connection of a personal
computer you have to use one of the communication
option boards.
NOTE: This RS232 port is not isolated.
Correct and safe use of a RS232 connection
depends on the ground pins of both ports
being the same potential. Problems can
occur when connecting two ports of e.g.
machinery and computers where both ground pins are
not the same potential. This may cause hazardous
ground loops that can destroy the RS232 ports.
The control panel RS232 connection is not galvanic
isolated.
The optional RS232/485 card is galvanic isolated.
Note that the control panel RS232 connection can
safely be used in combination with commercial available
isolated USB to RS232 converters.

Parameter set A contains parameters 43001 to
43556. The parameter sets B, C and D contains the
same type of information. For example parameter
43123 in parameter set A contain the same type of
information as 44123 in parameter set B.

Example:
We would like to control the inverter over a bus system
using the first two bytes of the Basic Control Message
by setting menu [2661] FB Signal 1 to 49972. Further,
we also want to transmit a 16 bit signed reference and
process value. This is done by setting menu [2662] FB
Signal 2 to 42905 and menu [2663] FB Signal 3 to
42906.
NOTE: It is possible to view the transmitted process
value in control panel menu Operation [710]. The
presented value is depending on settings in menus
Process Min [324] and Process Max [325].
The reference value is set in modbus number 42905.
0-4000 h corresponds to 0-100% of actual reference
value.
10.6 Description of the EInt
formats
Modbus parameters can have different formats e.g. a
standard unsigned/signed integer, or eint. EInt, which
is described below. All parameters written to a register
may be rounded to the number of significant digits
used in the internal system.
Serial communication
Omron SX inverter manual
If a parameter is in Eint format, the 16 bit number
should be interpreted like this:
F EEEE MMMMMMMMMMM
F
Format bit:
0=Unsinged integer
mode,
1=Eint mode
EEEE
2 complement signed
exponent
MMMMMMMMMMM
2 complement signed
mantissa.
If the format bit is 0, then can a positive number 032767 be represented by bit 0-14.
If the format bit is 1, then is the number interpreted as
this:
Value = M * 10^E
Value Binary
-8 1000
-7 1001
..
-2 1110
-1 1111
0 0000
1 0001
2 0010
..
6 0110
7 0111
The value represented by the EInt floating point format
is m·10e.
To convert a value from the EInt floating point format
to a floating point value, use the formula above.
NOTE: Parameters with EInt format may return values in
both formats (F=0 or F=1).
To convert a floating point value to the EInt floating
point format, see the code float_to_eint below.
Example
Example
If you write the value 1004 to a register and this register has 3 significant digits, it will be stored as 1000.
The number 1.23 would be represented by this in EInt
In the floating point format (F=1), one 16-bit word is
used to represent large (or very small numbers) with 3
significant digits.
If data is read or written as a fixed point (i.e. no decimals) number between 0-32767, the 15-bit fixed point
format (F=0) may be used.
F=Format. 1=floating point format, 0=15 bit as 15-bit
fixed point format.
F EEEE MMMMMMMMMMM
1 1110 00001111011
F=1 -> Eint
E=-2
M=123
The value is then 123x10-2 = 1.23
The matrix below describes the contents of the 16-bit
word for the two different EInt formats:
B15 B14 B13 B12 B11 B10 B9 B8 B7 B6 B5 B4 B3 B2 B1 B0

To activate the Motor ID run, select “Short” and press
Enter. Then press RunL or RunR on the control panel
to start the ID run. If menu [219] Rotation is set to L
the RunR key is inactive and vice versa. The ID run
can be aborted by giving a Stop command via the
control panel or Enable input. The parameter will automatically return to OFF when the test is completed.
The message “Test Run OK!” is displayed. Before the
VSD can be operated normally again, press the STOP/

[232] and the Mot I2t Time [233].
When the selection Trip is set in menu [231] the VSD
trips if this limit is exceeded.
When the selection Limit is set in menu [231] the VSD
reduces the torque if the integrated value is 95% or
closer to the limit, so that the limit cannot be
exceeded.
NOTE: If it is not possible to reduce the current, the VSD
will trip after exceeding 110% of the limit.
Example
• Menu [232] Mot I2t Curr is set to 100%.
1.2 x 100% = 120%
• Menu [233] Mot I2t Time is set to 1000 s.
This means that the VSD will trip or reduce after 1000
s if the current is 1.2 times of 100% nominal motor
current.
Thermal Protection [234]
Only visible if the PTC/PT100 option board is installed.
Set the PTC input for thermal protection of the motor.
The motor thermistors (PTC) must comply with DIN
44081/44082. Please refer to the manual for the PTC/
PT100 option board.

11.2.7 Trip Autoreset/Trip Conditions
[250]
The benefit of this feature is that occasional trips that
do not affect the process will be automatically reset.
Only when the failure keeps on coming back, recurring
at defined times and therefore cannot be solved by the
VSD, will the unit give an alarm to inform the operator
that attention is required.
For all trip functions that can be activated by the user
you can select to control the motor down to zero
speed according to set deceleration ramp to avoid
water hammer.
Also see section 12.2, page 158.

Autoreset example:
In an application it is known that the main supply voltage sometimes disappears for a very short time, a socalled “dip”. That will cause the VSD to trip an “Undervoltage alarm”. Using the Autoreset function, this trip
will be acknowledged automatically.

Number of Trips [251]
Off
Any number set above 0 activates the Autoreset. This
means that after a trip, the VSD will restart automatically according to the number of attempts selected.
No restart attempts will take place unless all conditions are normal.
If the Autoreset counter (not visible) contains more
trips than the selected number of attempts, the
Autoreset cycle will be interrupted. No Autoreset will
then take place.
If there are no trips for more than 10 minutes, the
Autoreset counter decreases by one.
If the maximum number of trips has been reached, the
trip message hour counter is marked with an “A”.
If the Autoreset is full then the VSD must be reset by a
normal Reset.

11.3.2 Process Settings [320]
With these functions, the VSD can be set up to fit the
application. The menus [110], [120], [310], [362]-[368]
and [711] use the process unit selected in [321] and
[322] for the application, e.g. rpm, bar or m3/h. This
makes it possible to easily set up the VSD for the
required process requirements, as well as for copying
the range of a feedback sensor to set up the Process
Value Minimum and Maximum in order to establish
accurate actual process information.
Process Source [321]
Select the signal source for the process value that
controls the motor. The Process Source can be set to
act as a function of the process signal on AnIn F(AnIn),
a function of the motor speed F(Speed), a function of
the shaft torque F(Torque) or as a function of a process
value from serial communication F(Bus). The right
function to select depends on the characteristics and
behaviour of the process. If the selection Speed,
Torque or Frequency is set, the VSD will use speed,
torque or frequency as reference value.
Example
An axial fan is speed-controlled and there is no feedback signal available. The process needs to be controlled within fixed process values in “m3/hr” and a
process read-out of the air flow is needed. The characteristic of this fan is that the air flow is linearly related
to the actual speed. So by selecting F(Speed) as the
Process Source, the process can easily be controlled.
The selection F(xx) indicates that a process unit and
scaling is needed, set in menus [322]-[328]. This
makes it possible to e.g. use pressure sensors to
measure flow etc. If F(AnIn) is selected, the source is
automatically connected to the AnIn which has Process Value as selected.

Example
Acceleration Time [331]
A conveyor belt is used to transport bottles. The
required bottle speed needs to be within 10 to 100
bottles/s. Process characteristics:
The acceleration time is defined as the time it takes for
the motor to accelerate from 0 rpm to nominal motor
speed.
10 bottles/s = 150 rpm
100 bottles/s = 1500 rpm
The amount of bottles is linearly related to the speed
of the conveyor belt.
NOTE: If the Acc Time is too short, the motor is
accelerated according to the Torque Limit. The actual
Acceleration Time may then be longer than the value
set.

Acceleration Time Motor Potentiometer
[333]
It is possible to control the speed of the VSD using the
motor potentiometer function. This function controls
the speed with separate up and down commands,
over remote signals. The MotPot function has separate ramps settings which can be set in Acc MotPot
[333] and Dec MotPot [334].
If the MotPot function is selected, this is the acceleration time for the MotPot up command. The acceleration time is defined as the time it takes for the motor
potentiometer value to increase from 0 rpm to nominal
speed.

Acceleration Time to Minimum Speed
[335]
If minimum speed, [341]>0 rpm, is used in an application, the VSD uses separate ramp times below this
level. With Acc>MinSpeed [335] and Dec<MinSpeed
[336] you can set the required ramp times. Short times
can be used to prevent damage and excessive pump
wear due too little lubrication at lower speeds. Longer
times can be used to fill up a system smoothly and
prevent water hammer due to rapidly exhausting air
from the pipe system.
If a Minimum speed is programmed, this parameter
will be used to set the acceleration time to the minimum speed at a run command. The ramp time is
defined as the time it takes for the motor to accelerate
from 0 rpm to nominal motor speed.

Sets the type of all the acceleration ramps in a parameter set. See Fig. 56. Depending on the acceleration
and deceleration requirements for the application, the
shape of both the ramps can be selected. For applications where speed changes need to be started and
stopped smoothly, such as a conveyor belt with materials that can drop following a quick speed change, the
ramp shape can be adapted to a S-shape and prevent
speed change shocks. For applications that are not
critical in this, the speed change can be fully linear

NOTE: For S-curve ramps the ramp times, [331] and

deceleration rated, i.e. linear part of S-curve, just as for
the linear ramps. The S-curves are implemented so that
for a speed step below sync speed the ramps are fully Sshaped while for larger steps the middle part will be
linear. Therefore will a S-curve ramp from 0 –sync speed
take 2 x Time while a step from 0–2 x sync speed will
take 3 x Time (middle part 0.5sync speed – 1.5sync
speed linear). Also valid for menu [337], D.eceleration

Spinstart [33A]
Sets the ramp type of all deceleration parameters in a
parameter set Fig. 57.
The spinstart will smoothly start a motor which is
already rotating by catching the motor at the actual
speed and control it to the desired speed. If in an
application, such as an exhausting fan, the motor
shaft is already rotating due to external conditions, a
smooth start of the application is required to prevent
excessive wear. With the spinstart=on, the actual control of the motor is delayed due to detecting the actual
speed and rotation direction, which depend on motor
size, running conditions of the motor before the Spinstart, inertia of the application, etc. Depending on the
motor electrical time constant and the size of the
motor, it can take maximum a couple of minutes
before the motor is caught.

11.3.8 PID Process Control [380]
The PID controller is used to control an external process via a feedback signal. The reference value can be
set via analogue input AnIn1, at the Control Panel
[310] by using a Preset Reference, or via serial communication. The feedback signal (actual value) must
be connected to an analogue input that is set to the
function Process Value.

PID sleep functionality
NOTE: The margin is always a positive value.
This function is controlled via a wait delay and a separate wake-up margin condition. With this function it is
possible to put the VSD in “sleep mode” when the
process value is at it’s set point and the motor is running at minimum speed for the length of the time set in
[386]. By going into sleep mode, the by the application
consumed energy is reduced to a minimum. When the
process feedback value goes below the set margin on
the process reference as set in [387], the VSD will
wake up automatically and normal PID operation continues, see examples.
PID sleep when less than minimum
speed [386]
If the PID output is equal to or less than minimum
speed for given delay time, the VSD will go to sleep.

PID Steady State Test [388]
In application situations where the feedback can
become independent of the motor speed, this PID
Steady Test function can be used to overrule the PID
operation and force the VSD to go in sleep mode i.e.
the VSD automatically reduces the output speed while
at the same time ensures the process value.
Example: pressure controlled pump systems with low/
no flow operation and where the process pressure has
become independent of the pump speed, e.g. due to
slowly closed valves. By going into Sleep mode, heating of the pump and motor will be avoided and no
energy is spilled.
NOTE: It is important that the system has reached a
stable situation before the Steady State Test is initiated.

Transition Speed Start [39E]
The transition speed start is used to minimize a flow/

When an additional pump needs to be switched on,
the master pump will slow down to the set transition
speed start value, before the additional pump is
started. The setting depends on the dynamics of both
the master drive and the additional drives.
The transition speed is best set by trial and error.
In general:
• If the additional pump has 'slow' start/stop dynamics, then a higher transition speed should be used.

When the application has a constant load over the
whole speed range, i.e. extruder or screw compressor,
the load type can be set to basic. This type uses a single value as a reference for the nominal load. This
value is used for the complete speed range of the
VSD. The value can be set or automatically measured.
See Autoset Alarm [41A] and Normal Load [41B]
about setting the nominal load reference.
The load curve mode uses an interpolated curve with
9 load values at 8 equal speed intervals. This curve is
populated by a test run with a real load. This can be
used with any smooth load curve including constant
load.

11.4.2 Process Protection [420]
Rotor locked [422]
Submenu with settings regarding protection functions
for the VSD and the motor.
With the rotor locked function enabled, the VSD will
protect the motor and application when this is stalled
whilst increasing the motor speed from standstill. This
protection will coast the motor to stop and indicate a
fault when the Torque Limit has been active at very low
speed for more than 5 seconds.
Low Voltage Override [421]
If a dip in the mains supply occurs and the low voltage
override function is enabled, the VSD will automatically
decrease the motor speed to keep control of the
application and prevent an under voltage trip until the
input voltage rises again. Therefore the rotating energy
in the motor/load is used to keep the DC link voltage
level at the override level, for as long as possible or
until the motor comes to a standstill. This is dependent on the inertia of the motor/load combination and
the load of the motor at the time the dip occurs, see
Fig. 79.

Overvolt control [424]
Used to switch off the overvoltage control function
when only braking by brake chopper and resistor is
required. The overvoltage control function, limits the
braking torque so that the DC link voltage level is controlled at a high, but safe, level. This is achieved by
limiting the actual deceleration rate during stopping. In
case of a defect at the brake chopper or the brake
resistor the VSD will trip for “Overvoltage” to avoid a
fall of the load e.g. in crane applications.
NOTE: Overvoltage control should not be activated if
brake chopper is used.

Analogue Input Selection via Digital Inputs:
When two different external Reference signals are
used, e.g. 4-20mA signal from control centre and a 010 V locally mounted potentiometer, it is possible to
switch between these two different analogue input signals via a Digital Input set to “AnIn Select”.
AnIn1 is 4-20 mA

DigIn3 is controlling the AnIn selection; HIGH is 4-20
mA, LOW is 0-10 V
[511] AnIn1 Fc = Process Ref;
set AnIn1 as reference signal input
AnIn1 Setup [512]
The analogue input setup is used to configure the analogue input in accordance with the signal used that will
be connected to the analogue input. With this selection the input can be determined as current (4-20 mA)
or voltage
(0-10 V) controlled input. Other selections are available
for using a threshold (live zero), a bipolar input function, or a user defined input range. With a bipolar input
reference signal, it is possible to control the motor in
two directions. See Fig. 80.
NOTE: The selection of voltage or current input is done
with S1. When the switch is in voltage mode only the
voltage menu items are selectable. With the switch in
current mode only the current menu items are
selectable.

11.5.6 Virtual Connections [560]
This function makes it possible to ensure that the relay
will also be closed when the VSD is malfunctioning or
powered down.
Functions to enable eight internal connections of comparator, timer and digital signals, without occupying
physical digital in/outputs. Virtual connections are
used to wireless connection of a digital output function
to a digital input function. Available signals and control
functions can be used to create your own specific
functions.
Example
Example of start delay
A process always requires a certain minimum flow. To
control the required number of pumps by the relay
mode NC, the e.g. the pumps can be controlled normally by the pump control, but are also activated
when the variable speed drive is tripped or powered
down.
The motor will start in RunR 10 seconds after DigIn1
gets high. DigIn1 has a time delay of 10 s.

With this function the source of the virtual connection

The comparators available make it possible to monitor
different internal signals and values, and visualize via
digital output or a contact, when a specific value or
status is reached or established.

There are 2 analogue comparators that compare any
available analogue value (including the analogue reference inputs) with two adjustable constants.
For the two analogue comparators two different constants are available, Level HI and Level LO. With these
two levels, it is possible to create a clear hysteresis for
the analogue comparator between setting and resetting the comparator output. This function gives a clear
difference in switching levels, which lets the process
adapt until a certain action is started. With such a hysteresis, even an instable analogue signal can be monitored without getting a nervous comparator signal.
Another function is to get a clear indication that a certain situation has occurred; the comparator can latch
by set Level LO to a higher value than Level HI.

connections [560].
Analogue Comparator 1 Value [611]
Selection of the analogue value for Analogue Comparator 1 (CA1).
Analogue comparator 1 compares the selectable analogue value in menu [611] with the constant Level HI in
menu [612] and constant Level LO in menu [613].
When the value exceeds the upper limit level high, the
output signal CA1 becomes high and !A1 low, see Fig.
86. When the value then decreases below the lower
limit, the output signal CA1 becomes low and !A1
high.
The output signal can be programmed as a virtual
connection source and to the digital or relay outputs.

Create automatic RUN/STOP signal via the analogue
reference signal. Analogue current reference signal, 420 mA, is connected to Analogue Input 1. AnIn1
Setup, menu [512] = 4-20 mA and the threshold is 4
mA. Full scale (100%) input signal on AnIn 1 = 20 mA.
When the reference signal on AnIn1 increases 80% of
the threshold (4 mA x 0.8 = 3.2 mA), the VSD will be
set in RUN mode. When the signal on AnIn1 goes
below 60% of the threshold (4 mA x 0.6 = 2.4 mA) the
VSD is set to STOP mode. The output of CA1 is used
as a virtual connection source that controls the virtual
connection destination RUN.

All nine alarm lists contain the same type of data. For
example DeviceNet parameter 31101 in alarm list 1
contains the same data information as 31151 in alarm
list 2. It is possible to read all parameters in alarm lists
2–9 by recalculating the DeviceNet instance number
into a Profibus slot/index number. This is done in the
following way:
slot no = abs((dev instance no-1)/255)
index no = (dev instance no-1) modulo 255
dev instance no = slot nox255+index no+1
Example: We want to read out the process value out
from alarm list 9. In alarm list 1 process value has the
DeviceNet instance number 31102. In alarm list 9 it
has DeviceNet instance no 31502 (see table 2 above).
The corresponding slot/index no is then:
slot no = abs((31502-1)/255)=123
index no (modulo)= the remainder of the division
above = 136, calculated as: (31502-1)-123x255=136

12. Troubleshooting, Diagnoses and Maintenance
12.1 Trips, warnings and limits
In order to protect the variable speed drive the principal operating variables are continuously monitored by
the system. If one of these variables exceeds the
safety limit an error/warning message is displayed. In
order to avoid any possibly dangerous situations, the
inverter sets itself into a stop Mode called Trip and the
cause of the trip is shown in the display.
Trips will always stop the VSD. Trips can be divided
into normal and soft trips, depending on the setup Trip
Type, see menu [250] Autoreset. Normal trips are
default. For normal trips the VSD stops immediately,
i.e. the motor coasts naturally to a standstill. For soft
trips the VSD stops by ramping down the speed, i.e.
the motor decelerates to a standstill.
“Limits”
• The inverter is limiting torque and/or frequency to
avoid a trip.
• The Limit relay or output is active (if selected).
• The Trip LED is blinking.
• One of the Limit status indications is displayed
(area D of the display).

12.2 Trip conditions, causes and
remedial action
12.2.1 Technically qualified
personnel
The table later on in this section must be seen as a
basic aid to find the cause of a system failure and to
how to solve any problems that arise. A variable speed
drive is mostly just a small part of a complete VSD system. Sometimes it is difficult to determine the cause of
the failure, although the variable speed drive gives a
certain trip message it is not always easy to find the
right cause of the failure. Good knowledge of the complete drive system is therefore necessary. Contact
your supplier if you have any questions.
Installation, commissioning, demounting, making
measurements, etc., of or at the variable speed drive
may only be carried out by personnel technically qualified for the task.
The VSD is designed in such a way that it tries to avoid
trips by limiting torque, overvolt etc.
Failures occurring during commissioning or shortly
after commissioning are most likely to be caused by
incorrect settings or even bad connections.
Failures or problems occurring after a reasonable
period of failure-free operation can be caused by
changes in the system or in its environment (e.g.
wear).
Failures that occur regularly for no obvious reasons are
generally caused by Electro Magnetic Interference. Be
sure that the installation fulfils the demands for installation stipulated in the EMC directives. See chapter 8.
page 45.
Sometimes the so-called “Trial and error” method is a
quicker way to determine the cause of the failure. This
can be done at any level, from changing settings and
functions to disconnecting single control cables or
replacing entire drives.
The Trip Log can be useful for determining whether
certain trips occur at certain moments. The Trip Log
also records the time of the trip in relation to the run
time counter.
WARNING: If it is necessary to open the VSD
or any part of the system (motor cable
housing, conduits, electrical panels,
cabinets, etc.) to inspect or take measurements as suggested in this instruction manual, it is
absolutely necessary to read and follow the safety
instructions in the manual.
12.2.2 Opening the variable speed
drive
WARNING: Always switch the mains voltage
off if it is necessary to open the VSD and wait
at least 5 minutes to allow the capacitors to
discharge.
WARNING: In case of malfunctioning always
check the DC-link voltage, or wait one hour
after the mains voltage has been switched
off, before dismantling the VSD for repair.
The connections for the control signals and the
switches are isolated from the mains voltage. Always
take adequate precautions before opening the variable
speed drive.
12.2.3 Precautions to take with a
connected motor
If work must be carried out on a connected motor or
on the driven machine, the mains voltage must always
first be disconnected from the variable speed drive.
Wait at least 5 minutes before continuing.
12.2.4 Autoreset Trip
If the maximum number of Trips during Autoreset has
been reached, the trip message hour counter is
marked with an “A”.

The variable speed drive is designed not to require any
servicing or maintenance. There are however some
things which must be checked regularly.
VSD is running and loaded. The design of the heatsinks is such that the fan does not blow the cooling air
through the interior of the VSD, but only across the
outer surface of the heatsink. However, running fans
will always attract dust. Depending on the environment the fan and the heatsink will collect dust. Check
this and clean the heatsink and the fans when necessary.
All variable speed drives have built-in fan which is
speed controlled using heatsink temperature feedback. This means that the fans are only running if the
If variable speed drives are built into cabinets, also

Output coils, which are supplied separately, are recommended for lengths of screened motor cable
longer than 100 m. Because of the fast switching of
the motor voltage and the capacitance of the motor
cable both line to line and line to earth screen, large
switching currents can be generated with long lengths
of motor cable. Output coils prevent the VSD from tripping and should be installed as closely as possible to
the VSD.

Description
Standby power supply kit for after mounting
The standby supply board option provides the possibility of keeping the communication system up and
running without having the 3-phase mains connected.
One advantage is that the system can be set up without mains power. The option will also give backup for
communication failure if main power is lost.
The standby supply board option is supplied with

• High signal on the digital input, e.g. terminal 9 in
Fig. 105, which is set to "Enable". For setting the
digital input please refer to section 11.5.2, page
126.
These two signals need to be combined and used to
enable the output of the VSD and make it possible to
activate a Safe Stop condition.
NOTE: The "Safe Stop" condition according to EN 954-1
Category 3 can only be realized by de-activating both the
"Inhibit" and "Enable" inputs.

13.8 Safe Stop option
To realize a Safe Stop configuration in accordance
with EN954-1 Category 3, the following three parts
need to be attended to:
1. Inhibit trigger signals with safety relay K1 (via Safe
Stop option board).
2. Enable input and control of VSD (via normal I/O
control signals of VSD).
3. Power conductor stage (checking status and feedback of driver circuits and IGBT’s).
To enable the VSD to operate and run the motor, the
following signals should be active:
• "Inhibit" input, terminals 1 (DC+) and 2 (DC-) on the
Safe Stop option board should be made active by
Omron SX inverter manual
Options
165
When the "Safe Stop" condition is achieved by using
these two different methods, which are independently
controlled, this safety circuit ensures that the motor
will not start running because:
• The 24VDC signal is taken away from the "Inhibit"
input, terminals 1 and 2, the safety relay K1 is
switched off.
The supply voltage to the driver circuits of the power conductors is switched off. This will inhibit the trigger pulses to
the power conductors.
6
5
4
3
2
1
• The trigger pulses from the control board are shut
down.
The Enable signal is monitored by the controller circuit
which will forward the information to the PWM part on the
Control board.
To make sure that the safety relay K1 has been
switched off, this should be guarded externally to
ensure that this relay did not refuse to act. The Safe
Stop option board offers a feedback signal for this via
a second forced switched safety relay K2 which is
switched on when a detection circuit has confirmed
that the supply voltage to the driver circuits is shut
down. See Table 33 for the contacts connections.
Fig. 103 Connection of safe stop option in size B and C.
To monitor the "Enable" function, the selection "RUN"
on a digital output can be used. For setting a digital
output, e.g. terminal 20 in the example Fig. 105,
please refer to section 11.5.4, page 132 [540].

1 2
When the "Inhibit" input is de-activated, the VSD display will show a blinking "SST" indication in section D
(bottom left corner) and the red Trip LED on the Control panel will blink.
5 6
To resume normal operation, the following steps have
to be taken:
• Release "Inhibit" input; 24VDC (High) to terminal 1
and 2.
• Give a STOP signal to the VSD, according to the
set Run/Stop Control in menu [215].
Fig. 104 Connection of safe stop option in size E and up.
• Give a new Run command, according to the set
Run/Stop Control in menu [215].
Table 33
NOTE: The method of generating a STOP command is
dependent on the selections made in Start Signal Level/
Edge [21A] and the use of a separate Stop input via
digital input.

at maximum of 40°C ambient temperature. However,
for most models, it is possible to use the VSD at
higher temperatures with little loss in performance.

14.7 Fuses, cable crosssections and glands
NOTE: The dimensions of fuse and cable cross-section
are dependent on the application and must be
determined in accordance with local regulations.
14.7.1 According IEC ratings
Use mains fuses of the type gL/gG conforming to IEC
269 or installation cut-outs with similar characteristics.
Check the equipment first before installing the glands.
NOTE: The dimensions of the power terminals used in the
models 4160 to 0 at 400V and 6315 to 61K0 at 690V
can differ depending on customer specification.
Max. Fuse = maximum fuse value that still protects the
VSD and upholds warranty.
