• The drive is intended to be used in industrial environments (Second
Environment). It achieves compliance with C3 category defined in IEC/EN
61800-3 standard when the installation recommendation within this
manual are followed.

• Select communication and control system according to the drive EMC
environment. Otherwise, systems could suffer from interferences due to a
low EMS level.

SAFETY

Before operating the drive, read this manual thoroughly to gain an understanding
of the unit. If any doubt exists, please contact POWER ELECTRONICS, (902 40

SAFETY INSTRUCTIONS

CONNECTION PRECAUTIONS

• To ensure a correct operation of the drive, it is recommended to use a
SCREENED CABLE for the control wiring.

• The motor cable should comply with the requirements within this manual.
Due to increased leakage capacitance between conductors, the external
ground fault protection threshold value should be adjusted ad hoc.

• Do not disconnect motor cables if the input power supply remains
connected.

• The internal circuits of the SD300 Series will be damaged if the incoming
power is connected and applied to the output terminals (U, V, W).

• Do not use power factor correction capacitor banks, surge suppressors, or
RFI filters on the output side of the drive. Doing so may damage these
components.

• Before wiring the terminals, make sure that the inverter keypad display is
turned off and the front cover is off as well. The inverter may hold a high
voltage electric charge long after the power supply has been turned off.

EARTH CONNECTION

• The drive is a high frequency switching device; therefore, leakage current
may flow. Ground the drive to avoid electric shock. Use caution to prevent
the possibility of personal injury.

• Connect the input PE terminal only to the dedicated PE terminal of the
drive. Do not use the case, nor chassis screws for grounding.

• Ground the drive chassis through the labelled terminals. Use appropriate
conductors to comply with local regulations. The ground conductor should
be connected first and removed last.

• Motor ground cable must be connected to the PE output terminal of the
drive and not to the installation’s ground. We recommend that the section
of the ground conductor (PE) is equal or greater than the active conductor
(U, V, W).

TRIAL RUN

• Verify all parameters before operating the drive. Alteration of parameters
may be required depending on application and load.

• Always apply voltage and current signals to each terminal that are within
the levels indicated in this manual. Otherwise, damage to the drive may
occur.

Drive Mounting

The SD300 variable speed drives are designed to be mounted on a wall or
inside a panel.

The inverter can become very hot during operation. Install the inverter on a
surface that is fire-resistant or flame-retardant and with sufficient clearance
around the inverter to allow air to circulate. Make sure to follow the clearance
recommendations in “Clearances” section.

Hang the SD300 drive through the anchorages placed on the rear part of the
drive on a solid wall or structure which supports the drive weight and the
possible forces generated by the wiring.

Use a level to draw a horizontal line on the mounting surface and mark the
fixing points. Then, drill the two upper mounting bolt holes, and then install
the mounting bolts. Do not fully tighten the bolts yet.

Mount the drive using the two upper bolts, and then fully tighten the mounting
bolts. Ensure that the SD300 is placed flat on the mounting surface.

MECHANICAL INSTALLATION

Note: The quantity and dimensions of the mounting brackets vary based on
frame size. Please refer to “DIMENSIONS” section to find the information
that corresponds to your model.

There is an optional flange for special installations. If you have ordered this
option, please refer to “Flange Type” section for installation instructions.

Clearances

The SD300 VFD must be installed in vertical position, and firmly fastened
through the dedicated anchorages placed in the rear part of the drive that
avoid any movement.

If the equipment is installed inside a cabinet, ensure that the hot air expelled
from the VFD flows outside. This hot air can recirculate, and cause the drive
to suffer from overheating. To guarantee a suitable ambient temperature,
avoid the recirculation of air and follow the minimum clearance distances, as
indicated below.

If you wish to install two or more drives in a technical room or cabinet, mount
them side by side in a horizontal arrangement (do not stack one on top of the
other), it is necessary to remove the top cover using a screwdriver and
respect the minimum clearances in order to ensure proper cooling of the
product.

Installing multiple drives

NOTICE

Remove the top cover of the drives when they are mounted in a
horizontal arrangement.

Otherwise, the equipment can get damaged and the warranty will be
voided.

MECHANICAL INSTALLATION

Cooling

The heat sources inside the equipment correspond to the inverter bridge
(IGBTs), rectifier bridge and the input filter.

The drive has at least one cooling fan (this varies depending on the drive
size) at the bottom, the hot air is then dissipated through the gratings on the
top side.

Cooling airflow for SD300

It is possible to replace the cooling fans without dismounting the whole
equipment. To do this, unscrew the screws in the fan corners and disconnect
the connector.

Installation

Install the drive following the
recommendation within this manual in
relation with the cooling requirements,
position, clearances, wiring access and
ground connection.

DC reactor

(optional)

DC reactors also contribute to improving the
power factor and harmonics reduction, but
DC reactors are usually used in facilities
with higher power supply capacity.

Motor cables

Select and install the motor cables
according to the recommendation within this
manual and the applicable national and
local codes, otherwise you could cause
EMC filtering malfunction and motor
damage.

Motor

Do not connect power factor capacitors,
surge arrestors or RFI filters to the output
side of the drive.

Topology

SD300 drive operates according to the principle of pulse-width modulation
(PWM). By varying the power supply voltage and the grid frequency, it is
possible to control the speed and torque of the connected induction three­phase motors by means of its main components: rectifier bridge, the DC bus,
inverter bridge, and power and control board.

The SD300 includes a gate drive and a control board to control the rectifier
thyristor diode’s bridge triggering, the inverter IGBT’s bridge triggering, the
soft charge, the DC bus voltage and the motor performance. In addition, the
control board integrates the interface terminals such as communication
ports, the digital and analogue inputs and outputs, display, etc.

As standard, the input and output terminals are made of tin plated copper. If
they are oxidized prior to its installation, the terminals will be poorly
connected and this is a cause of overheating. To avoid this effect, clean the
terminal lugs and all contact surfaces with ethanol and follow the
recommended cable section.

Use insulated ring lugs when connecting the power terminals.

CAUTION

Line voltage (input supply) must never be connected to U, V and W
terminals.

Incorrect connection will result in the drive being damaged.

It is necessary that the installer guarantees the correct observance of
the law and the regulations that are in force in those countries or areas
where this device is going to be installed.

Do not use capacitors for power factor correction, surge suppressors,
or RFI filters on the output side of the drive. In doing so, the components

could get damaged.

Use shielded and three-wire braided cable and ground. Do not use single­core wires.

If the drive settings are set by default (switching frequency 3 kHz), make sure
that the total cable length does not exceed:

• 100 m (328ft) for unshielded wires.

• 50m (165ft) for shielded wires.

For other switching frequencies, lengths may vary.
Voltage drop is calculated by using the following formula:

Voltage Drop (V) = [√3 x cable resistance (mΩ/m) x cable length (m) x
current(A)] / 1000

The power cables must have a sufficient power rating in order to prevent
overheating and voltage drops. The installer must consider the cable cross­section, cable type, routing method and the ambient conditions to select the
appropriate cable. It is only permitted the use of cooper or aluminum cables.

NOTICE

Do not exceed the motor cable distances. Longer cables can cause

reduced motor torque in low frequency applications due to the voltage drop,
increase circuit susceptibility to stray capacitance which may trigger over­current protection devices or result in a malfunction of the equipment
connected to the drive.

Ground Connection

Before connecting the power conductors, make sure that the chassis of the
drive and the adjoining cabinets are connected to ground through the
dedicated (PE) terminals. The PE terminals are located in the bottom part of
the drive and labelled with the appropriate ground connection.

PE terminals location

Motor chassis grounding must be connected to the drive. In other words,

connect the motor’s ground conductor to the PE output terminal of the drive
and not to the installation’s ground. We recommend that the cross section of
the motor’s ground conductor (PE) should have at least the cross section of

the active conductor (U, V, W). Additionally, it should be installed following
the recommendations indicated in previous sub-section.

When connecting the earth, ensure that all connected terminal lugs are
securely tightened and protected from mechanical forces. Check the
recommended tightening torque in “Recommended Cable” table, from this

EMC Installation Requirements

Introduction

The EMC European Directive defines electromagnetic compatibility as the
capability of an apparatus, an industrial plant, or a system to work
satisfactorily in the electromagnetic environment, without at the same time
causing electromagnetic disturbances in the apparatus, industrial plant or
systems present in the same environment.

The Electromagnetic Compatibility (EMC) depends on two main
characteristics of the equipment: Electromagnetic Interference (EMI) and
Electromagnetic Susceptibility (EMS). The EMC standards aims to ensure
that all the electrical equipment that could operate simultaneously in the
same environment are compatible. This means that the interference
immunity of all the devices is greater than the interference emission of all
the devices within the same environment.

The EMC requirements for Power Drive System (PDS) are defined in
IEC/EN 61800-3 standard that is included in the Declaration of conformity
CE enclosed. In the European Union, EN61800-3 standard takes priority
over all generic standards. The PDS in the context of this standard
comprises the drive converter, the motor cables and the motor. Therefore,
the installer as the ultimate responsible must follow the installation
instructions given within this manual.

For safety reasons, it is essential to measure the grounding resistance
of the installation. This must be established before the first start up of the
plant and with the drive disconnected.

The installer is responsible of providing the adequate amount, type
and cross section grounding conductor alongside the characteristics
of the drive used and the plant, in order to minimize the grounding
resistance, which must comply with local and national regulations.

SD300

POWER ELECTRONICS

64

POWER CONNECTIONS

Depending on the location of the drive, the standards define four
categories distributed in two environments.

• First Environment: Domestic installations. It also
includes premises directly connected to a low-voltage
power supply network without an intermediate
transformer which supplies buildings used for domestic
purposes such as shopping malls, cinemas, hospitals…

• Second environment: Industrial installations. Second
Environment includes all plants other than those
directly connected to the public low-voltage network
which supplies buildings used for domestic purposes,
e.g. factories and those other premises supplied by
their own dedicated transformer.

[2] C4 Category applies only for complex systems or when ratings are equal or above
to 1000 V or 400 A wich are unable to comply with the limits of C3 Category. In these
cases, C4 Category can be achieved by adjusting the equipment in situ and applying
the EMC recommendations.

SD300 compliance

SD300 variable speed drives with Extended EMC have been designed for
the industrial use (Second Environment). In the case of the Standard EMC
equipment, an external filter must be installed to meet C3. The correct
installation following the recommendations within this manual, permit to
achieve compliance with C3 category defined in IEC/EN 61800-3.

Optionally, the SD300 drive with non-floating earth can be installed in
residential areas (First Environment) by employing optional RFI filters that
permit to achieve the C2 category.

The SD300 is not a retail unit. It is neither a plug in device nor a movable
device and it is intended to be installed and commissioned by qualified
personnel. However, C1 category will not be required.

The SD300 with floating earth configuration can be installed in industrial
(Second Environment) IT grids. Equipment with Extended EMC comply
with C3 (Second Environment). In the case of the Standard EMC
equipment, an external filter must be installed to meet C3.

EMC Recommendations

To conform the EMC directive, it is necessary that these instructions be
followed as closely as possible. Follow the usual safety procedures when
working with electrical equipment. All electrical connections to the filter,
inverter and motor must be made by a qualified electrical technician.

1. Check the filter rating label to ensure that the current, voltage
rating and part number are correct.

2. For best results, the filter should be fitted as closely as possible to
the incoming mains supply of the wiring enclousure, usually
directly after the enclousures circuit breaker or supply switch.

3. The back panel of the wiring cabinet of board should be prepared
for the mounting dimensions of the filter. Be sure to remove any
paint etc from the mounting holes and face area of the panel to
ensure the best possible earthing of the filter.

4. Mount the filter securely.

5. Connect the mains supply to the filter terminals marked LINE,
connect any earth cables to the earth stud provided. Connect the
filter terminals marked LOAD to the mains input of the inverter
using short lengths of appropriate gauge cable.

6. Connect the motor and fit the ferrite core (output chokes) as close
to the inverter as possible. Armoured or screened cable should be
used with the 3 phase conductors only threaded twice through the
center of the ferrite core. The earth conductor should be securely
earthed at both drive and motor ends. The screen should be
connected to the enclousure body via and earthed cable gland.

7. Connect any control cables as instructed in “Wiring
Recommendations” section, inside “CONTROL CONNECTION”
section.

It is important that all lead lengths are kept as short as possible and that
incoming mains and outgoing motor cables are kept well separated.

Connection

It is recommended the use of braided shielded motor cables to achieve
compliance with C3 category. Wiring and Installation recommendations
are included in previous sections: “Power Connection and Wiring”,
“Ground Connection” and “EMC Installation Requirements”.

In shielded cables it is recommended to connect the shield by making 360°
contact in both the drive cabinet and the motor terminal box. As an
example, EMC cable glands can be installed as shown in the next figure.

POWER CONNECTIONS

It is recommended to use shielded cable for control signals and to follow
recommendations included in Wiring Recommendations section.

CAUTION

Select communication and control system according to the drive EMC
environment. Otherwise, systems could suffer from interferences due to a

low EMS level.

Protections

Safety Stop Function

Safe Torque Off (STO) allows the drive output to be disabled so that the
drive cannot provide power or generate torque in the motor.

The Safe Torque Off function meets EN ISO 13849-1 PLd and EN 61508
SIL2 (EN60204-1, stop category 0). This feature is standard and enables
compliance with current safety standards. See “STO” point, inside
“CONTROL CONNECTION” section for further information.

Ground Fault Protection

The drive is equipped with an internal software, the ground fault protective
function protects the drive against input and output unbalanced currents.
For further information, see the Programming and Software Manual.

This function is not intended to work as a safety or fire protection, so an
external protection must be provided to ensure that a substantial ground
fault current is promptly interrupted. The SD300 drives are compatible to
operate with Type B RCDs, if it is required. The EMC filters and long motor
cables increase the ground leakage currents, so the threshold response
of the protection should be adjusted to suit the surrounding plant
conditions. For additional information, contact with Power Electronics.

Motor Thermal Protection

The drive includes a motor thermal protection that, based on the motor
performance parameters, mathematically calculates the thermal reservoir
of the motor. When this reservoir is reduced below the limits, the drive
automatically stops the motor. The thermal sensitivity is configured in the
programming parameters. For further information consult Software and
programming manual.

Others

The drive can implement additional motor and drive protections such as
power-loss ride through, automatic fly restart, high and low input and
output voltage, pump overload and underload... For further information,
consult Software and Programming manual.

Dynamic Braking Resistors

CAUTION

Do not touch the braking resistor during the drive operation. It could
be very hot (over 150ºC).

A dynamic brake controls the regenerated energy. The dynamic brake
activates an IGBT to discharge the DC bus over external resistors when the
DC voltage overpasses a pre-set value.

SD300 drives include a built-in dynamic brake as standard. The user only
has to connect a resistor between terminals P2 and B of the power board
(see “Power Terminals” section).

Wiring Recommendations

Before planning the installation, follow these recommendations. The parallel
cable routing should be minimized and the distance between the control
wiring and the power wiring should be maximized. It is recommended to route
control cables with different voltages in separate cable racks, trays or ducts.

It is recommended to use shielded twisted cable for all the data, signal or
control cables that exit the variable speed drive, with the shield correctly
bonded to ground. To ensure an effective shield bonding, it is recommended
to include in the SD300 front metal panel of the control board, EMC shield
clamps that ensure a 360º effective shield bonding.

Shield bonding

Digital signal cables must be grounded at both ends of the cable (when there
is no potential difference between equipment). It is recommended to use
independent shielded cables for digital and analogue signals. When using
multiple analogue signals do not use common return for them. If a low­interference is experienced (hum loops) using analogue signals disconnect
the shield grounding from one of the ends. Please refer to section
“Recommended Cable Section” for wire specifications and recommended
tightening.

STO - Safe Torque Off

The STO function is defined as follows:
Power, that can cause rotation, is not applied to the motor. The frequency

converter will not provide energy to the motor, which can generate torque.
For three-phase asynchronous motor, that means to stop supplying

alternating three-phase power to the stator.
This function is included as standard in SD300 drives and corresponds with

an Emergency Stop Category 0 according to IEC 60204-1. When the drive
is running and the STO function is applied, the motor will freely stop by its
own inertia.

The SD300’s STO function permits to achieve two Safety Levels for the STO
function. The safety integrity level SIL2 (PLe) requires the use of an external
SELV/PELV 24VDC source, emergency push button, and a safety relay SIL2
certified with feedback. For safety integrity, level SIL1 (PLc) it is only required
an external push button.

By using this function, cleaning, emergencies or maintenance work on non­electrical parts of the machinery can be performed without switching off the
input power supply to the drive.

Based on the study of each application and a risk assessment, the designer
should define the safety function required and each safety level.

CONTROL CONNECTION

81

The safety input function meets EN ISO 13849-1 PLd and EN 61508 SIL2
(EN60204-1, stop category 0)

Safe input function circuit

CAUTION

The STO safety function does not disconnect the main input power
and auxiliary power supply. The drive disconnects the output motor
power supply. Therefore, active conductors may be present inside so
do not carry out electrical maintenance tasks without isolating the
drive. Otherwise, it could cause damage to the equipment and lead to injury
and even death.

Do not use the STO function as a normal drive stop.

According to EN 60204-1 automatic restart is not allowed after an
emergency stop. For this reason, the machine control must prevent
an automatic start after emergency stop.

COMMISSIONING

9. COMMISSIONING

CAUTION

Only qualified personnel are allowed to commission the drive. Read
and follow the safety instructions on the first pages of this manual.
Neglecting the safety instructions can cause injuries or even death.

Ensure that there is no voltage present in the input power terminals
and no voltage can be connected to the drive inadvertently.

This chapter does not include all the tasks to be performed during
commissioning, follow local and national regulations.

In order to carry out a commissioning correctly, we recommend checking the
following steps:

Check the compatibility of the upstream protections (circuit breaker, fuses,

etc...) that could cause an unexpected stop during the soft charge.

Verify that the line voltage is compatible with drive voltage range. If not, the

drive could get damaged.

Connect input, PE and output power wiring, and verify that they are correctly

installed and fastened.

10. MAINTENANCE

SD300 drives consist of advanced semiconductor devices. Temperature,
humidity, vibration and deteriorated components can reduce their efficiency.
To avoid any possible irregularities, we recommend making periodic
inspections.

Cooling

It is possible to replace the cooling fan without dismounting the whole
equipment. To do this, unscrew the screws and disconnect the connector.

The following image shows the standard fan usage rate. Replacement level
can be set in parameter Pr.87.

MAINTENANCE

Warnings

▪ Make sure to disconnect the input power while performing

maintenance.

▪ Make sure to perform maintenance after checking the DC Link

capacitor has discharged. Check that the voltage between DC
terminals +, - is below DC 30V. The bus capacitors in the drive main
circuit can still be charged even after the power is turned off.

▪ The correct output voltage of the drive can only be measured by

using an RMS voltage meter. Other voltage meters, including digital
voltage meters, are likely to display incorrect values caused by the
high frequency PWM output voltage of the drive.

Routine Inspection

Make sure to check the following points before handling the drive:

▪ Installation site conditions.
▪ Drive cooling system conditions.
▪ Excessive vibrations or noise in the motor.
▪ Excessive overheating.
▪ Normal output current value on the monitor.

SCREEN

DESCRIPTION

-

The equipment is operative. No fault is present.

Overload. The drive trips when the output current reaches the value
set in parameter Pr.21, exceeding the time limit set in parameter
Pr.22. The protection is operative if the parameter Pr.20 has been
set with a value different to 0 ‘NONE’.

Underload. The motor is working with insufficient load. The drive
trips when its current is within the values set in parameter Pr.29 and
Pr.30 exceeding the time limit set in parameter Pr.28. The protection
will be enabled if the parameter Pr.27 has been set with a value
different to 0 ‘NONE’.

Inverter Overload. The drive cuts the output supply when the
output current exceeds the value set in the corresponding
parameters (150% for 1 minute, 200% for 3 seconds of the drive
rated current). Protection is based on drive rated capacity, and may
vary depending on the device capacity.

E-Thermal. The internal thermo-electronic protection determines
the motor overheating. If the motor is overheated, the drive stops its
output. The protection is enabled setting the parameter Pr.40 to a
value different than 0 ‘NONE’.

Ground Fault. The drive trips when an earth leakage and its current
exceed the internal value configured in the drive. The overload
protection function will protect the drive from any ground fault
caused by a small leakage resistance.

Output Ph Loss. One of the three output phases is open. The

protection will be enabled if the parameter Pr.5 is set as 1 ‘OUTPUT’
or 3 ‘ALL’.

Input Ph Loss One of the three input phases is open. The
protection will be enabled if the parameter Pr.5 is set as 2 ‘INPUT’
or 3 ‘ALL’.

WARNING & FAULT MESSAGES

SCREEN

DESCRIPTION

NTC. The drive uses a NTC thermal sensor to detect temperature

increases within the supply system. When this message is
displayed, the thermal sensor cable may have been cut. (The drive
will continue running).

Overcurrent. The drive trips when the output current exceeds the
200% of the rated current value.

Overvoltage. The drive trips if the DC voltage within bus exceeds
the value established. This value has been established in the
internal configuration during the deceleration process or when the
motor regenerative energy return to the drive is excessive for the
capacitors which compose the DC bus. This fault can also be
caused due to a transitory overvoltage within the supply system.

External Trip. This function can be used whenever the user needs
to cut the output by the use of an external trip signal. The open
/closed contact use will depend on the configuration within the digital
inputs (In.65-In.71) configured as 4 ‘EXTERNAL TRIP’. The drive
cuts the motor output protecting it from the controlled situation within
the terminal.

Short ARM. The drive trips when a short-circuit occurs in the IGBT
or in the output power.

Overheat. The drive trips if overheated caused by a damaged
cooling fan or by the presence of any strange substance within the
cooling system.

Fan trip. An anomaly detecting within the cooling fan. The
protection will be enabled if parameter Pr.79 is set as 0 ‘TRIP’.

Param_Wr_Err. A problem has been detected during the writing of
a parameter by keypad.

Pipe Fill Flt. An error has been detected which makes the PID
feedback be always under the established value. Possible pipe
breakdown.

External Brake. Drive trips when the braking unit reaches a
dangerous temperature.
