Chapter 1 - Safety Precautions
In compliance with EEC directives make sure that all the safety devices required by EC standard 89/
392/CEE governing industrial automation have been incorporated in the drive before attempting to
operate it. These directives apply only in Europe and have no validity on the American continent.
This drive controls mechanical movements. It is the responsibility of the end user to ensure that
these movements do not themselves cause any danger. Do not bypass or tamper with the drive
manufacturers safety interlocks or operating limits.
Risk of fire and electric shock!
When using test apparatus like oscilloscopes to take measurements from electrically live equipment
always connect the body of the oscilloscope to ground and always use a differential amplifier. To
ensure accurate readings choose probes and terminals with care and make sure that the oscilloscope
is correctly set up. Refer to the manual provided by the oscilloscope manufacturer for details of how
to operate and adjust the oscilloscope correctly .
Risk of fire and explosion!
Installation of the drive in hazardous areas and in the presence of flammable substances or
combustible vapours or powders can lead to fire or explosion. Install the drive well away from
hazardous areas even if the controlled motor is suitable for use under such conditions.
Risk of crushing!
Incorrect lifting of the drive can cause serious or even fatal injury. Only suitably trained personnel
should lift the drive and even then only with suitable lifting equipment.
Connect the drive and the motor to ground in compliance with applicable national electrical standards.
Replace any covers that may have been removed before powering up the drive. Failure to comply
with this precaution can lead to serious injury or even death.
This variable frequency drive is electrical equipment designed for use in industrial installations.
Parts of the drive are electrically live while it is functioning. The drive must therefore be installed
and opened only by a qualified electrician. Incorrect installation of the drive or the controlled motor
can damage the drive and lead to damage and injury.
The drive has no over-speed protection other than software based protection logic. Carefully follow
the instructions given in this manual and observe all local and national safety standards.
Always connect the drive to a protective earth (PE) through the ground terminals (PE2) and the
metallic casing (PE1). PIX drives and their AC power input filters have an earth leakage current
greater than 3.5 mA. EN 50178 standard specifies that in the presence of earth leakage currents
greater than 3.5 mA the ground connection cable (PE1) must be fixed and must be doubled for
redundancy.
In the event of a fault even if the drive has been disabled it may still cause sudden movements if it
has not been disconnected from the mains power.
Never open the drive or remove any covers while the drive is connected to the mains power supply.
See section 5.9 in this manual for the minimum delay that must be respected before any work on the
drives terminals or internal components can be performed.
Never connect the drive to mains supplies with voltage levels outside the specified range. Excess
voltage can damage the drives internal components.
It is forbidden to operate the drive without a correct ground connection. The casing of the motor
must also be grounded separately from the drive to avoid interference.
The ground connection must be comply with national electrical standards or the Canadian Electrical
Code. The drive must be grounded using a closed loop connector certified to UL and CSA standards
sized to match the gauge of the wire used. The connector must be fitted using the crimping tool

8  Chapter 1 - Safety Precautions User Manual
specified by the connector manufacturer.
Never perform insulation testing between drive terminals or control circuit terminals.
Do not install the drive in environments where temperature exceeds the specified maximum. Ambient
temperature plays a major role in drive reliability.
If the drive displays any alarm condition refer to the TROUBLESHOOTING section later in this manual
and recommence normal operation only once the problem has been solved. Do not use an external
routine or other such methods to reset alarms automatically.
The drive must be secured to a partition or panel constructed from heat resistant materials. The
temperature of the drives cooling fins can reach 90°C during normal functioning.
Do not touch or tamper with any drive component during normal functioning. In particular do not
alter gaps between insulation or remove insulation or covers from the drive.
Protect the drive against physical and environmental stress (high temperature humidity impact
etc.).
Never apply voltage to the drives output terminals (U2 V2 W2). Likewise never connect other
drives in parallel with the drives own outputs or bypass the drive by connecting its inputs directly to
its outputs.
Do not connect capacitive loads like power factor correction capacitors to the drives output terminals
(U2 V2 W2).
Only qualified electricians should install and start up the drive. The electrician so doing is directly
responsible for ensuring that there is an adequate ground connection and that power cables are
protected in accordance with local and national standards. The controlled motor must also be
protected against overload.
Do not perform dielectric rigidity testing on any parts of the drive. Only use appropriate test instruments
(with a minimum internal resistance of 10 kΩΩ
ΩΩ
Ω/V) to measure signal voltage.
NOTA!Stora e of the drive for periods lon er than two years could lead to malfunctionin of the DC
link capacitors. These must be re enerated prior to use as follows.
Before startin up the drive, leave it connected to the mains power supply for at least two
hours with no load. The drive must be connected to the power supply but not enabled in
order to re enerate the capacitors.
NOTA!The terms inverter, controller and drive are interchan eable in industrial automation
contexts. This manual uses the terms drive and inverter.

1.1 Power and ground connections
1) TDE Macno S.P.A. drives are desi ned for use with standard three phase mains power supplies, symmetrical with
respect to round (TN or TT mains supplies).
Sin le phase drives must be connected to one phase, neutral and round. Three phase drives must be connected
to all three phases plus round.
2) In the case of an IT mains supply, use a star/delta transformer with secondary wirin referenced to round.
If IT mains power is used, loss of insulation in onen of the other devices connected to the same circuit
can cause the drive to malfunction if no star/delta transformer is provided.

Chapter 2 - General Description
DVS di ital drives are desi ned to control the speed of three phase electric motors. They can control motors with a power
ran e from 0.25 kW to 0.75 kW (220 - 240 V) and from 0.35 HP up to 1 HP (220 V).
The drive rectifies the volta e of the mains power supply to obtain an intermediate circuit volta e, then uses an inverter brid e
applyin sinusoidal PWM modulation to enerate a three phase power supply with variable volta e and frequency permittin
re ular, smooth motor control even at very low speeds.
Feed volta es to the various control cards are obtained from a switchin power supply that also draws its power from the
intermediate circuit.
The inverter brid e is based on IGBT (Insulated Gate Bipolar Transistor) devices. Output is protected a ainst short circuits
between the phases and to round. If more than one motor is driven in parallel by a sin le drive (obviously of adequate power)
motors can be switched in and out independently even durin normal drive functionin (see section 5.2.3).
If the motors used are not specifically desi ned for inverter control, a drop in output current of around 5 - 10% must be
allowed for. If nominal torque is demanded from such a motor at low speeds, an auxiliary motor coolin fan will be necessary
to dissipate the heat enerated. If the necessary coolin assistance cannot be provided, then the motors will have to be over-
sized. In either case the user should contact the technical service of the motor manufacturer for further information.
If a motor has to function at a frequency reater than its nominal frequency, the user should a ain contact the manufacturers
technical service to ascertain what mechanical problems (bearin wear, balancin problems, etc.) could be incurred.
DVS drives can be controlled in a number of ways:
- via their control terminals
- usin the control keys and display
- over an RS 485 serial line
- usin a standard PC control pro ram
Note!
The electronic control circuit terminals are electrically separate from the power circuit terminals, but the
control microprocessor is linked to the potential of the DC sta e.

Disposing of the drive
DVS drives must be disposed of as electronic waste in compliance with national le islation.
The front covers are made from recyclable ABS.
. .2. Mains input and drive output connections
DVS drives must be connected to a mains supply capable of providin symmetrical short circuit power better than or equal
to the values iven in table 3.3.2.1. See section 5.7.1 for information on the addition of mains chokes.
See table 3.3.2.1 for the permitted mains volta es. Cyclical phase direction is irrelevant. Volta es below the minimum
tolerance threshold cause the drive to lock.
The drive can be restarted automatically after an alarm condition occurs (see section 6.15 for further details on this function).
NOTA!Under certain circumstances it may be essential to add mains chokes and EMI filters to the drive input.
Refer to the Chokes and filters section.
DVS drives and mains input filters have earth leaka e currents reater than 3.5 mA. EN 50178 standard requires that in the
presence of earth leaka e currents reater than 3.5 mA, the round connection (to the PE terminal) must be fixed.

. . . Mains input current
The mains input current to the drive depends on the duty status of the controlled motor. Table 3.3.2.1
shows nominal continuous duty values (IEC 146 class 1) with typical output power factors for each
model of drive.
. .4. Output
The output from DVS drives is protected a ainst short circuits between phases and to round.
NOTA!It is forbidden to connect any external volta e to the drives output terminals! Nevertheless, once a motor
has been disabled, it can be disconnected from the drive output while the drive is still functionin .
The nominal continuous output current value (ICONT) depends on mains volta e (Kv), ambient temperature (KT) and switchin
frequency (KF) if hi her than the default frequency:
ICONT = I2N x KV x KT x Ksw (see table 3.3.2.1 for reduction factors), with a maximum overload capacity of IMAX = 1.5 x ICONT
for 60 seconds.

User Manual Chapter 3 - Description, Components and Specifications  19
Recommended motor power
The combinations of nominal motor power and inverter model specified in table 3.3.2.1 is based on the use of motors whose
nominal volta es correspond to that of the mains power supply.
If the motors involved have other volta es, select the drive model on the basis of nominal motor current.
NOTA!Maximum permitted overload: 136% . I2N cl.1 º150% . I2N cl.2.
Table 3.3.3.1 shows nominal current values for the most typical duty profiles (ambient temperature =
40°C, standard switchin frequency).
A similar criterion should be applied to drive operation with additional declassin factors.
