ATV71Q Products

With the ATV71Q you decide in favour for an utmost multifunctional frequency inverter which covers a very wide range of applications by means of its option possibilities and numerous functions.

The frequency inverters are designed for liquid cooling of the power electronics. Due to the continuously use of corrosion-resistant steel (stainless steel) in the cooling circuit it is possible to use industrial water, clean water with or without corrosion protection or a water-glycolmixture for cooling. As the design of the cooling element is especially robust, the inverter can be operated in closed cooling systems as well as in open cooling systems.

The exceedingly user-friendly LCD operating panel or the

PC software can be selected for operation.

In addition to the standard terminals, terminal extension cards, fieldbus options and the possibility of the speed feedback are available to control.

Optimized device features suitable for your application range:

Application Device features

Liquid cooling for reduction of the lost heat in the electrical room

When several inverters with high power are installed in an electrical room, the heat dissipation is often problematic. At the devices of type ATV71Q the losses of the power electronics are dissipated by the cooling liquid. Only the remaining losses of the inverter are exhausted by the device-internal fans.

Thus helps to prevent an increase of temperature inside the enclosure and the installation of an external air conditioning unit can be avoided.

Liquid cooling to increase the protection degree of the enclosure

Coupled drive systems

Due to the ambient conditions there are often enclosures with higher protection degree required. That can be realized for air-cooled inverters of high power only with extraordinary expenses. At the devices of type ATV71Q the losses of the power electronics are directly dissipated by the cooling liquid. The remaining losses are exhausted from the enclosure via an airwater-heat exchanger. Usually the air-water-heat exchanger is dimensioned in such a way that it also covers the losses of the other components (line reactor, motor choke, ...) of the enclosure.

− Master/Slave control for balanced load distribution with group drives

−

Simple possibility of coupling the DC link provides an optimum balance of energy

−

Safety function "Safe Standstill" also with coupled drives

ELECTROMAGNETIC FIELDS "ELECTRO SMOG"

WARNING

Electromagnetic fields are generated by the operation of electrical power engineering installations such as transformers, inverters or motors.

Electromagnetic fields can interfere with electronic devices (like heart pacemakers), which could cause them to malfunction. It is therefore forbidden for persons with heart pacemakers to enter these areas.

The plant operator is responsible for taking appropriate measures, labels and hazard warnings to adequately protect operating personnel and others against any possible risk:

•

Observe the relevant health and safety regulations.

• Display adequate hazard warning notices.

•

Place barriers around hazardous areas.

•

Take measures, e.g. using shields, to reduce electromagnetic fields at their source.

•

Make sure that personnel are wearing the appropriate protective equipment.


CAUTION

INCOMPATIBLE LINE VOLTAGE

Before turning on and configuring the drive, ensure that the line voltage is compatible with the supply voltage range shown on the drive nameplate. The existing nominal mains voltage must be set at the drive by means of a parameter. Thereby an optimal adjustment of the undervoltage protective function takes place. The drive may be damaged if the line voltage is not compatible.

Failure to follow this instruction can result in injury or equipment damage.

WARNING

DAMAGE OF THE DEVICE

Do not install or operate the drive or accessories, when they are damaged.


WARNING

RISK OF TOPPLING

Do not stand the drive upright. Keep the drive on the pallet until it is installed.

Use a hoist for installation. Therefore the components are equipped with handling lugs.



Checking the scope of delivery

Check whether the specification on the name plate complies with those of the order.

Storage

Storage temperature -25°C to 70°C

If the inverter is disconnected over a longer period, the performance of its electrolyte capacitors is reduced.

But due to the "active balancing system" no special treatment of the frequency inverter is necessary when the maximum storage time has not been exceeded:

•

12 months at a maximum storage temperature of +50°C

•


•


WARNING

RISK OF FREEZING OF COOLANT DURING STORAGE

Ensure that there is no coolant left in the cooling circuit when storing the drive or that the coolant will not freeze at the planned storage temperature.


CAUTION

EXCEEDING THE MAXIMUM STORAGE TIME

When the maximum storage time has been exceeded, operate the ATV71Q without load for minimum one hour. We recommend to execute this process already after a shutdown period of 6 months.



General

General specification

Quality

CE Marking

All devices and drives of the electric drive engineering may cause electromagnetic interferences and otherwise they may be influenced by such interferences. Therefore, they are subject to the EMC directive 2004/108/EEC since 1.1.1996.

The frequency inverters have an operating voltage which is clearly in the range of 50...1000 V AC or

75...1500 V DC. Therefore, they are also subject to the Low-voltage directive 2006/95/EEC since 1.1.1997.

Because of the radio frequency interference filters which are built into the frequency inverters they are in conformity with EN 61800-3 and EN 61800-5-1 .

Frequency inverters are not considered as machines with at least one mechanically moving part. Therefore, they are not subject to the Machine directive 2006/42/EEC.

CAUTION

PROTECTION AGAINST HIGH-FREQUENCY INTERFERENCES

Frequency inverters are a product of the restricted sales according to IEC 61800-3. In a residential environment this product can cause radio frequency interferences whereupon the user can be called on to take suitable measures.


The frequency inverters have a CE marking on the rating plate. However, it is necessary to observe the installation regulations to achieve the corresponding limits.

Installation regulations

−

The ATV71Q frequency inverters include a radio frequency interference filter for industrial environments which is built-in as standard. In case of long motor cables and for the use in residential environment the implementation of an additional external filter is necessary to reduce the current harmonics on the mains caused by the DC link.

− Installation on a well-grounded metallic mounting plate with good HF connection between motor cable screen and filter

− Use of screened (shielded) motor cables, proper connection of the motor cables on both ends or proper laying in a metallic, closed and interconnected cable conduit

−

Use of a motor choke in case of high motor cable lengths

−

Use and proper connection of screened (shielded) control cables

−

Grounding of the frequency inverter for human protection with at least 10 mm 2 (AWG 6)

−

Consider the protective separation when preparing control lines and coupling relays

−

Separate laying of the motor cables from other cables, especially from the control wiring

General | 13

Mains conditions

Mains voltage

The frequency inverters are designed for the following mains voltages:

•

ATV71Q ●●● N4:

3 AC 380 V -15 % to 440 V +10 %, 50 Hz

±

5 %

3 AC 380 V -15 % to 480 V +10 %, 60 Hz

±

5 %

•

ATV71Q ●●● Y:

3 AC 500 V -15 % to 690 V +10 %, 50/60 Hz ± 5 %

The existing nominal mains voltage must be set at the inverter by means of a parameter. Thereby an optimal adjustment of the undervoltage protective function takes place.

CAUTION

INCOMPATIBLE LINE VOLTAGE

Before turning on and configuring the drive, ensure that the line voltage is compatible with the supply voltage range shown on the drive nameplate. The existing nominal mains voltage must be set at the drive by means of a parameter. Thereby an optimal adjustment of the undervoltage protective function takes place. The drive may be damaged if the line voltage is not compatible.


Fan supply

The inverters ATV71Q ●●● Y need an auxiliary voltage supply in addition to the mains voltage:

3 AC 400 V -10 % to 440 V +10 %, 50 Hz

±

5 %

3 AC 400 V -10 % to 480 V +10 %, 60 Hz ± 5 %

Fuses

The Altivar frequency inverters do not contain any input fuses. These must be provided externally (see chapter "Fuses and terminals ") which helps to protect the power cables from overload and the input rectifier in the event of an internal short circuit.

It is recommended to use super fast (semiconductor) fuses. Standard fast fuses or circuit breakers can also be used but the rectifier could be damaged in case of an internal short-circuit current.

14 | General

Braking unit / Braking resistor

The frequency inverters ATV71Q have parameters to monitor the braking power.

The correct setting of the braking parameters is required for the protection of the braking resistor in normal operation. In case of short-circuit of the internal braking transistor or of the external braking unit, the braking resistor can be only protected by mains disconnection. Therefrom a line contactor is necessary when using the braking function. Furthermore, the use of the function "Line contactor control ( LLC )" is recommended.

CAUTION

OVERLOAD OF THE BRAKING RESISTOR

Ensure for protection of the braking resistor that the correct data of the resistor are set at the inverter.

If the braking resistor does not match the overload characteristic to be used or the local regulations require an additional protective device, a thermal relay should be integrated into the mains disconnection mechanism.


General | 15

Nongrounded mains

The use of the frequency inverters is basically in all network variants permitted.

TN or TT mains

(factory default)

IT mains or

Corner grounded

In case of nongrounded mains a single ground (earth) fault in the supplying mains has no effect to the function of the inverter. If the ground (earth) fault occurs in the motor or the motor cables, the inverter is switched off.

But the recognition heavily depends on the ground (earth) capacitance of the mains.

CAUTION

RISK OF DAMAGE OF THE INTERNAL EMC-FILTER

Set the internal filter in accordance to your mains conditions.

Do not operate ATV71Q ●●● Y devices in "Corner Grounded Networks


16 | General

Radio frequency interferences

The Altivar frequency inverters include a built-in radio frequency interference filter as standard. These filters fulfil the requirements for category "C3 – industrial environments" according to EN/IEC 61800-3 (in the past:

EN 55011 class A group 2).

For using inverters of higher power in residential environment and in case of longer motor cables, additional

EMC filters are available as option for the ATV71Q ●●● N4.

CAUTION




Mains current harmonics / Mains voltage distortion

Because of using a diode rectifier on the input of the inverter harmonics occur in the mains current which lead to a voltage distortion of the supplying mains.

There are several possibilities to reduce this current harmonics and to decrease the total mains current:

− Use of a three-phase choke in the mains lines

− 12-pulse-connection

The supply results from a separate transformer with two out-of-phase secondary windings.

The following devices are prepared for 12-pulse-supply as standard:

ATV71QC31N4...C50N4

ATV71QC40Y…C63Y

−

Active Front End unit option AFE connected upstream

General | 17

12-pulse supply

Some frequency inverters are standard equipped with two parallel input rectifiers and therefore are suitable for a 12-pulse rectification.

The supply results from a separate transformer with two out-of-phase secondary windings (e.g. superimposing transformer Yy6 Yd5). On the main side of the transformer the 5 th and 7 th current harmonics are practically nonexistent as they have been cancelled by the shifted transformer windings.

NOTICE

If the mains is already distorted by other loads (e.g. frequency inverter with normal 6-pulse-circuit), a superimposing transformer in zig-zag-connection ( ± 15° phase shift at each secondary windings e.g. Yy1130

Yy0030) will be highly recommended.

*) Line reactors are only necessary if a transformer is used for several inverters or if the transformer power is notedly larger than the inverter power.

CAUTION

RISK OF DAMAGE OF THE INTERNAL EMC-FILTER

In case of 12-pulse supply the radio frequency interference filters integrated in the frequency inverter must be reconnected onto setting "IT mains".


The following specifications must be kept:

Harmonics level

In a 12-pulse supply system many harmonics are compensated nearly to zero in the mains side of the 3windings transformer due to a phase shifting of the secondary windings. Therefore 12-pulse supply is a simple solution for harmonic mitigation.

The following lines show the harmonic values based on a mains voltage without any disturbances:

In a typical medium voltage network the THD(u) value can be assumed with 3 %. Due to this voltage harmonics there is no total compensation of harmonics.

Voltage harmonics in the mains supply lead to a different current value for both rectifier bridges. In bad conditions the current can be different by 20 % (10 %).

NOTICE

Passive filters cannot be used together with 12-pulse solution.

20 | General

Mains impedance / Short-circuit current

The Altivar frequency inverters are designed considering a maximal permitted mains short-circuit current of the supply (values see technical data of the respective frequency inverter).

NOTICE

By means of using line reactors (available as option) considerably higher mains short-circuit powers are possible.

Power factor correction systems

Frequency inverters cause current harmonics in the supplying mains. When a power factor correction system is used, their capacitors are additionally stressed by means of the harmonics.

CAUTION

PROTECTION AGAINST RESONANCES

We recommend the installation of chokes for the affected system parts, which helps to protect against overload due to resonances of the power factor correction system.


Switching rate

The inverters can be directly switched on and off by means of the line contactor which can be easy controlled via a relay output of the inverters.

In case of frequent start/stop commands it is recommended to realize them by means of the logic control inputs (or via a serial bus) directly to the electronics of the inverter.

NOTICE

By means of the certificated control input "PWR" a "Safe Standstill" of the drive is considering the safety category according to EN 954-1 / ISO 13849-1 (and IEC/EN 61800-5-2). Thus a line or motor contactor can be saved.

Inverter control

The inverter is controlled by means of connecting and disconnecting the line supply voltage.

Switching rate max. 60 switching operations per hour

(safety category 1, stop category 0)

Disconnection of the motor by means of a motor contactor depending on the motor contactor

(safety category 1, stop category 0)

Electronic start/stop commands by means of the logic inputs of the inverter arbitrary

Electronic lock of the inverter by means of the control input PWR "Safe Standstill" arbitrary

(safety category 3, stop category 0 or 1)

NOTICE

The control of the device fans takes automatically place dependent from the start command and a temperature-dependent lag function.

General | 21

Protection of the plant

Responsibility

All stated connection recommendations and planning remarks are to be taken merely as suggestions which must be adapted to the local conditions and regulations concerning installation and usage.

This applies especially to the safety regulations for machines, the EMC regulations and the general regulations for human protection.

HUMAN PROTECTION AND MACHINE SAFETY

WARNING

The users are responsible to integrate the frequency inverter into the protection and safety concept of the plant or machine.


Frequencies > 60 Hz

CAUTION

OPERATION AT FREQUENCIES > 60 Hz

Check whether the used components are qualified for operation at frequencies higher than 60 Hz. Ask the manufacturer of the motor and the machine if necessary.


Overvoltage protective circuit

A free-wheeling diode is provided for DC control circuits.

For AC control circuits the R/C wiring is preferable compared to a wiring with varistors because as a result not only the peak overvoltage is reduced but also the rise-time.

CAUTION

RISK OF MALFUNCTIONS IN THE CONTROL CIRCUITS

All inductances like relays, contactors, magnetic brakes, etc. have to be equipped with an overvoltage protective circuit. It helps to prevent malfunctions of the conventional device control as well as of the fieldbus.

The protective circuit must be qualified for inverter operation !


22 | General

Automatic restart

The internal function "automatic restart ( Atr )" switches the inverter automatically on after each mains switchon or mains recurrence without the line fault having to be confirmed. This function increases the availability, especially for drives that are not integrated into the plant control via a fieldbus system.

The automatic restart takes place in case of:

•

Switch-on of the line supply voltage (only in case of 2-wire control and dependent on the selected undervoltage behaviour)

•

after a line fault (only in case of 2-wire control and dependent on the selected undervoltage behaviour)

•

after each trip confirmation (only in case of 2-wire control – level rated)

•

after a fast stop or emergency stop (only in case of 2-wire control – level rated)

DANGER

UNINTENDED EQUIPMENT OPERATION

Make sure that there is no risk for persons or equipment in case of an automatic restart.

Failure to follow this instruction will result in death or serious injury.

General | 23

Residual current circuit breaker

Frequency inverters, especially those with additional EMC filters and screened (shielded) motor cables, lead an increased leakage current against ground (earth).

The leakage current depends on:

•

the length of the motor cable

•

the type of laying and whether the motor cable is screened (shielded) or not

•

the set pulse frequency

•

the use of an additional radio frequency interference filter

• the grounding of the motor at its installation place (grounded or nongrounded)

Depending on the conditions, the leakage current of plants with high cable lengths can be absolutely higher than 100 mA !

The built-in residual current detection has no current-limiting effect. It only helps to protect the drive and is no human protection.

CAUTION

INCORRECT TRIGGERING OF THE RESIDUAL CURRENT CIRCUIT BREAKER

Particularly because of the capacitors of the radio frequency interference filter, an unintentional triggering of an ground (earth) leakage circuit breaker may occur at the moment of switching on. As well, the ground

(earth) capacitances may cause an incorrect triggering during operation. On the other hand, it is possible that the triggering is blocked by means of DC components which are caused by the mains rectification at the input of the inverter.

Therefrom, you should observe following:

■ Only use short-time delayed and pulse current sensitive residual current circuit breakers with considerably higher tripping current.

■ Protect the other loads by means of a separate residual current circuit breaker.

■ Residual current circuit breakers in front of an inverter do not provide absolutely reliable protection in case of direct contact !! So they should be always used in combination with other protective measures.

■ The frequency inverters have no current-limiting effect (in case of residual currents) and therefore they do not violate the protective multiple grounding.

Failure to follow these instructions can result in equipment damage.

Locking of the frequency inverter

The ATV71Q devices include the standard protective function "Safe Standstill" (Power Removal, certificate no.

72148-2 /2006), which helps to prevent any unintended start-up of the motor. This function fulfills, when correctly wired, the machine standard EN 954-1 / ISO 13849-1 safety category 3, the IEC/EN 61508 SIL2 standard for functional safety and the power drive system standard IEC/EN 61800-5-2.

24 | General

Operation of ATEX motors in explosive atmospheres

The ATV71Q frequency inverters integrate the "Power Removal" safety function which prohibits unintended equipment operation. The motor no longer produces torque. The use of the "Power Removal" safety function allows the ATV71Q frequency inverter to be installed as a part of the safety-related electrical, electronic and programmable electronic control systems, dedicated to the safety of a machine or an industrial process. This safety function complies with the standard for safety of machinery EN 954-1 / ISO 13849-1, category 3. It complies also with the standard for functional safety IEC/EN 61508 and with the power drive systems product standard IEC/EN 61800-5-2, SIL2 capability.

The use of the "Power Removal" safety function also allows the use of the ATV71Q frequency inverters to control and command motors installed in explosive atmospheres (ATEX).

Wiring and connection

Wiring diagram

The following diagrams show the typical wiring of the frequency inverters including the options which may be required for protection of the plant or the device, depending on the application.

Description of the used abbreviations:

ATV ....................... Frequency inverter

HS ......................... Main switch (to be used if required according to the local regulations)

NH......................... Mains fuses considering table "Fuses and terminals " (absolutely necessary)

NS ......................... Mains contactor (to be used if required according to the local regulations)

TS.......................... Disconnecting switch (to be used according to the local regulations)

TR ......................... Transformer with two out-of-phase secondary windings (e.g. Yy6 d5)

Line reactor........... Line reactor to reduce the current harmonics on the mains caused by the DC link

RFI ........................ Option radio frequency interference filter to use the inverter considering category C2 according to EN 61800-3 "Use in 1st environment - residential environment" internal filter .......... Radio frequency interference filter built-in as standard considering category C3 according to EN 61800-3 "Use in industrial environments"

Motor choke ......... Motor choke to reduce the voltage peaks at the motor in case of long motor cables

BU .........................

Braking unit

BR ......................... Braking resistor for short deceleration time or short-time dynamic loads

DC+ / DC-............. Power supply from a DC-bar; alternatively to 3AC mains supply.

1. The inverter supply is split upstream to the line reactors.

2. The monitoring of the fuses helps to protect the inverter against unbalanced line currents. It must act on line contactor or pulse inhibit (e.g. digital input "External trip"). It is not absolutely necessary as the inverter monitors the mains voltage. Therefor parameter

IPL

"Input phase loss" must be set to "YES" (factory default).

3. In case of supply by means of a three-winding-transformer the neutral point can be grounded or alternatively an insulation monitoring relay can be used.

4. Please observe chapter "12-pulse supply", page 18 for specification of the transformer.

Fuses and terminals

CE

The ATV71Q frequency inverters do not contain any input fuses. They have to be provided externally for the case that the electronic protective mechanism of the inverter did not work. So they are a secondary protection of the inverter which helps to protect the power cables against overload and the input rectifier against an internal short-circuit.

It is recommended to use super fast (semiconductor) fuses. Standard fast fuses or circuit breakers can also be used but the rectifier could be damaged in case of an internal short circuit.

To protect the rectifier in case of a short-circuit the used fuses should not exceed the following I 2 t values

(referring to 10 ms):

DANGER


If the mains fuses blow the inverter already has a primary defect. Therefore, exchanging the blown fuses and switching the inverter on again is not effective. Consequently, the use of circuit breakers is not advantageous and has additionally the disadvantage of a slower switch-off ad. A circuit breaker with motor drive has to be seen in fact as an alternative to the line contactor.



UL/CSA

In addition to semiconductor fuses (with UL approval, nominal values in accordance with column Mains fuses

"inverter protection" "sf") the use of class J and class T fuses according to the tables below is permitted.

The inverters are designed for operation on a transformer with matching power. In case of networks with higher short-circuit power an external choke is necessary and it is recommended to reduce the current harmonics.


DC coupling

DC-coupling of several ATV71Q with a line contactor

It is advisable to couple the DC links in case of applications which have to perform rated motor power on the one hand and which should act also in generator operation due to the energy exchange over the DC link on the other hand (e.g. roller conveyors, conveyer belts,...).

NS .........................Line contactor

Because of the installation of a common line contactor, the charging circuits of the individual inverters act in parallel when the mains is switched on and thus they cannot be overloaded.

NH .........................Device protection on the main side

In order to help to protect each rectifier against overload, keep the recommended fuses in chapter "Fuses and terminals ". Consequential damages of the charging circuit during mains switch-on can be avoided by using a fuse monitoring which acts on the digital input

"External fault" or on the line contactor.

SI...........................Fuse in the DC link according to table in chapter " Fuses for DC-coupled inverters", page 44

, , ................Frequency inverter

Basically , the number of devices and their size is arbitrary, but between the biggest and smallest device only three power ratings are possible.

Line reactor...........The option line reactor is absolutely necessary !

BU / BR.................Braking unit and braking resistor for short-time reduction of the generator power

For example, if the drives should be shut down at the same time, the resulting energy will be relieved in the braking resistor.

The use of a braking unit is not obligatory.

NOTICE

The ATV71Q frequency inverters can be operated at the same DC bus. However, some parameters have to be adjusted appropriate (see Programming manual).

DANGER


•

Check DC link wiring before switch-on the mains.

•

Do not disconnect and connect drives to the DC bus during operation and while the DC bus is not discharged.

•

In case of wrong wiring of the DC link, e.g. due to exchanging terminals PA/+ and PC/- or a ground (earth) fault, the inverter may be damaged or destroyed.



ATV71Q master drive with slave(s) at the DC link

Applications, which include drives which operate as generator (during braking operation) as well as one or several drives which operate as motor, can act very economic in case of a DC supply (e.g. re-/unwinder, straighteners, motor test benches, roller conveyors, hoisting applications,...).

WARNING

OVERLOAD OF THE RECTIFIER

•

At any time there must not be needed more motor power than power which is required for the rectifier of the main drive (e.g. 250 kW (400 HP) + 20 % for 60 s for ATV61QC25N4 or ATV71QC20N4).

• DC supplied drives must not be connected during operation !


........................... Frequency inverter (main drive)

This inverter defines the maximum possible motor power of the whole drive group. It is able to charge three similar devices (or several smaller devices with same total power).

, ................... DC supplied inverters (slaves)

Line reactor........... The option line reactor is absolutely necessary !

SI........................... Semiconductor fuse according to table in chapter " Fuses for DC-coupled inverters", page 44.

BU / BR................. Braking unit and braking resistor for short-time reduction of the generator power

For example, if the drives should be shut down at the same time, the resulting energy will be relieved in the braking resistor.

The use of a braking unit is not obligatory.

NOTICE

At the master drive the braking function has to be activated. The slave(s) have to be parameterized for operation with an external braking unit.

DANGER


•

Check DC link wiring before switch-on the mains.

•

Do not disconnect and connect drives to the DC bus during operation and while the DC bus is not discharged.

•

In case of wrong wiring of the DC link, e.g. due to exchanging terminals PA/+ and PC/- or a ground (earth) fault, the inverter may be damaged or destroyed.

Internal / External fan supply at ATV71Q

●●●

N4

At the ATV71Q devices there is additionally to the water cooling of the power part an air circulation via AC fans. These fans are supplied by the mains from the inverter as factory default. Alternatively also an external voltage supply is possible (e.g. Inverter supply via DC bus).

Internal supply (delivery state)

If the external fan supply is used, the connectors X1 and X4 of the fan control board have to be exchanged and an auxiliary voltage with the following technical data has to be provided:

Fan voltage: 380 V -10 % … 440 V +10 % / 50 Hz ±5 %

380 V -10 % … 480 V +10 % / 60 Hz ±5 %

Power: ATV71QD90N4 … C13N4: 550 VA

ATV71QC16N4 … C25N4: 1100 VA

ATV71QC31N4 … C50N4: 2200 VA *)

*) VW3 A7 102: 550 VA

In case of low charge the power part fans are switched off depending on the temperature. The fans for the control part start running as soon as the inverter is applied with voltage.

Life cycle of fans: approx. 48,000 hours

The ambient condition has an effect on the life cycle of the fans.

If the inverter is permanently supplied with mains voltage, the control part fans should be replaced precautionary after five years!

Basic notes for connection

1. Power cables , especially motor cables, with single wires should be laid closely bundled with the corresponding PE conductor.

2. Control , mains supply and motor output should be arranged separately from each other, if possible.

3. Do not lay control cables , mains supply or motor cables in the same cable conduit.

4. Use only screened (shielded) control cables (exception: relay contacts and possibly digital inputs if they are laid completely separated from the power cables). Ground the screen at both ends (exception: In case of problems with ground loops due to compensation currents which heat the screen, only the signal input side is grounded or a parallel compensation line is used).


5. Perform EMC grounding of the RFI filter, the mounting plate and the cubicle.

The inductance of "grounding" is extremely significant for the influences on other loads. That means that ground connections with large surface, which are arranged parallel to the yellow-green protective grounding

PE, are particular important.

WARNING

RISK OF INFLUENCES TO OTHER LOADS

Install low impedance ground (earth) connection for each drive.


6. The motor cable screen returns the interference currents back to the line filter of the inverter.

Furthermore the motor cable screen reduces the radiated emissions as well as the coupling into neighbouring lines.

Therefore, screened (shielded) 4-pole motor cables should be used and the screen should be connected at both ends in accordance with the valid HF rules. The type of screen material (copper or steel) is less important than the well connection at both ends. Alternatively, a closed and well conductive cable conduit can be used which is continuously connected.

A cheap alternative (for the use in industrial environments) for large cable diameters are power cables with concentric protective conductor (e.g. NYCY or NYCWY). Thereby, the protective conductor assumes the protective function of the PE conductor as well as the screening effect.

Safe Standstill

The ATV71Q frequency inverters include the "Safe Standstill" function as standard (Power Removal, certificate no. 72148-2 /2006).

This safety function complies with:

− the standard for safety of machinery EN 954-1 / ISO 13849-1, category 3

−

the standard for functional safety IEC/EN 61508, SIL2 capability

(functional safety of processes and systems and electrical/electronic/programmable electronic safetyrelated systems)

The SIL (Safety Integrity Level) capability depends on the connection diagram for the drive and for the safety function.

−

the definition of the product standard IEC/EN 61800-5-2 for both stop functions:

−

Safe Torque Off (“STO”)

−

Safe Stop 1 (“SS1”)

Following circuit variations are provided:

Circuit variation using a line contactor using a motor switch using the digital input PWR "Safe

Standstill" using the digital input PWR "Safe

Standstill" with controlled deceleration

Safety function

Safety category 1 according to EN 954-1 category 1; IEC/EN 61508, SIL1

Stop category 0 according to IEC/EN 60204-1







The ground (0 V) can float up to 35 V compared to PE. The connection 0 V - ground necessary to limit the voltage can therefore e.g. also occur far away in the PLC (if necessary by the analog output related to 0 V).

The analog input AI1 with differential amplifier (as well as AI3 of the extended I/O extension card) enables the reference assignment decoupled from the ground.

DANGER

UNEXPECTED OPERATION OF THE DEVICE

Keep the maximum cable length of 15 m when wiring the safety input PWR "Safe standstill".



The device fulfills the requirements for protective separation between power and electronic connections according to EN 61800-5-1.

DANGER


All connected external equipments must fulfil the requirements for protective separation.

The use of the individual inputs and outputs as well as their limits can be adjusted by means of the device software. Only the alternative use of the logic input LI6 for motor thermistor monitoring and the selection of the switching method for the logic inputs has to be adjusted by means of the sliding switch.

The inverters ATV71Q are equipped with a built-in interface for control via Modbus. In addition to the external wiring (connection to the T-pieces in the bus line) only the adjustment of few parameters is necessary.

Alternatively, this interface can be also used for the CANopen bus. Therefore, an adapter (VW3 CAN A71) is required for conversion of the RJ45 plug to SUB-D (CANopen standard CiA DRP 303-1). The bus wiring is taken by connection to the next device.

Installation remarks

Wall-mounting

The inverters ATV71Q are designed for installation on the wall, in an electrical room or into an enclosure. The devices are built according to pollution degree 2. If the environment does not correspond to these conditions then the necessary transition of the pollution degree must be provided e.g. by means of an enclosure.

2 Cooling water inlet

3 Cooling water return

4 Cooling air for control part

5 Cooling air for power part (only capacitors)

CAUTION

RISK OF OVERHEATING

Before startup check whether the connection of the waterpipes is corrects. Interchanged connection leads to an overheating.



Cubicle installation IP23

Reduction of heat losses in the electrical room

The water cooling of the ATV71Q inverters enables a high reduction of the heat losses accumulating in the electrical room. Thus the installation of an expensive air conditioning can be avoided.

The cooling water circuit can exhaust about 85 % of the accumulating heat losses out of the inverter enclosure. The heat losses of control electronics, wiring, line and motor choke, fuses and so on are cooled via forced air cooling.

The illustration shows the typical enclosure design in protection degree IP23.

CAUTION

RISK OF OVERHEATING OF THE FREQUENCY INVERTER AND COMPONENTS

When the frequency inverter is installed without any elements for routing the air flow like in the example above, adequate openings for air in- and outlet must be provided.

ATV71QD90N4…C13N4 and ATV71QC11Y...C16Y: Minimum cross section 4 dm²

ATV71QC31N4…C50N4 and ATV71QC40Y...C63Y: Minimum cross section 10 dm²



Cubicle installation IP55

Completely closed enclosure

The water cooling of the ATV71Q inverters enables in combination with an additional air/water heat exchanger the dissipation of 100 % of the accumulating heat losses out of the enclosure. Thereby the enclosure (the enclosure group) is absolutely sealed and does not require any air exchange with the environment.

The temperature of the external cooling water is about +5...+35°C, the air temperature outside the enclosure can be up to +50°C.

The illustration shows the typical enclosure design in protection degree IP55.

CAUTION


The additional heat exchanger has to be dimensioned in such a way that it can absorb next to the control heat losses of the inverter also the heat losses of other enclosure components (wiring, line reactors and motor chokes, ...).

The device-internal fan can be used to force the necessary air circulation.



Remarks for cooling

Division of heat losses

The heat losses of the frequency inverter are divided into power part heat losses, which are exhausted by the cooling water, and the heat losses of the control part, which are exhausted by device-internal fans to the ambient air.

The real heat losses of the individual inverters are given in chapter "Dimensions", page 58.

Control of the cooling circuit

CAUTION


Make sure that

•

the frequency inverter is never operated without cooling.

•

the coolant pump is running as soon (or better before) the start command is given.

•

the inverter changes to impulse inhibit when the pump breaks down or is running dry.

•

the coolant pump continues running for at least 5 minutes in order to avoid reheating.


Connecting remarks for the cooling circuit

During installation of the inverter observe enough free space above the device (min. 200mm) for laying the cooling pipes.

Consider the tightening torque of 35 Nm (310 lb.in) for the pipe connections in order to avoid damages of the internal pipe system.

The connection can be realized as straight or swivel elbow connection.

•

Use only the specified pipe connectors

Failure to follow these instructions can result in death, serious injury or equipment damage.


Leak-tightness

WARNING

RISK OF LEAKS IN THE COOLING CIRCUIT

Before filling the cooling circuit, check the whole circuit for leaks preferably with air and soap sud.


Coolant

Due to the robust design of the cooling pipes inside the inverter, different types of coolant can be used:

−

Industrial water (process water)

The cleanness of the water and the content of aggressive materials is significant for the availability and the maintenance intervals of the whole drive unit. Thus it is recommended to check the process water for the following limits:

−

pH-value 6…9

−

Degree of hardness < 20°dH

−

Chlorides

−

Iron

< 100 mg/l

− Particle 300 m

−

Water-glycol-mixture

At a mixture ratio of 60 % water and 40 % Antifrogen N (company Clariant) the freezing point is at -25°C. A higher glycol ratio reduces the heat conduction, a lower ratio reduces the frost resistance.

The coolant corresponds with water pollution class 1 according VwVwS 1999. Observe DIN 52 900 (about propandiol and ethylene glycol) when disposing the coolant.

−

Clear water (de-ionized water)

For UL applications the use of clear water is necessary, whereby admixing a ratio of 0.2…0.25 % for protection against corrosion (type NALCO TRAC 100) is allowed. Regular check of the insulation of the liquid is requested by the supplier NALCO.

WARNING

RISK OF FREEZING OF COOLANT

Ensure that the ambient temperature corresponds to the specifications of the coolant to avoid freezing.


CAUTION

RISK OF CORROSION DAMAGES INSIDE THE COOLING CIRCUIT

•

Ensure that all components of the cooling circuit comply with the requirements of the coolant!

•

Use only the specified cooling liquid.

When an additional air/water heat exchanger (serial to the inverter) is provided for cooling of the enclosure air, it has to be dimensioned according to the flow rate through the inverter.

CAUTION


Guarantee the necessary flow rate for the cooling circuit as described in the table above.



Temperature

The inlet temperature of the coolant to the inverter has to be in the range of +5°C...+55°C. In order to help to prevent condensate formation, the temperature of the coolant may be at most 10°K colder than the temperature inside the enclosure (depending on the relative humidity).

Keep the temperature of the coolant during operation as constant as possible.

CAUTION

RISK OF CONDENSATE FORMATION

Avoid condensation at the cooling circuit. Therefore set the temperature for the coolant according to the table above.


Pressure

The pressure in the cooling system of the inverter must be 1.5…2.5 bar when the pump is not running. During operation the pressure can increase for up to 3 bar (total pressure 4.5 … 5.5 bar).

DANGER

RISK OF COOLING CIRCUIT BURST

■ The maximum pressure in the cooling circuit must not exceed 8 bar!

■ Install an overpressure safety valve. In order to meet the requirements of UL/CSA, an overpressure valve of type KLUNKE VALVE 918BDCV01BJE0116 has to be used.


De-aerating

De-aerating of the cooling system is done manually during commissioning. Thereby no special de-aerating of the inverter is necessary because it takes place automatically due to the high flow rate. For de-aerating during operation an automatic vent has to be installed.

CAUTION


Make a complete de-aerating of the cooling system during commissioning.



Cooling systems

Open cooling circuit

In this system the frequency inverter is directly cooled with industrial water. Because of the wide temperature range and the exclusive use of corrosion-resistant steel in the cooling water pipes, the inverter is optimally prepared for this simple type of cooling system. Plane pipe walls and a generous flow cross-section also have a share in the high availability of the cooling system.

Due to the wide temperature range, also the serial connection of several aggregates (like motor, enclosure cooling, ...) in the cooling circuit is possible when observing the flow rate and condensation.

Reference value: +40...+55°C

CAUTION

RISK OF OVERHEATING AND CONDENSATION

Make sure that the lost heat from the power part of the inverter is dissipated and prevent condensation of the heat sink.

• The coolant pump has to be switched on when the inverter is started.

•

Avoid condensation by using an adequate system for controlling the temperature inside the cooling circuit.

•

The power of the coolant pump has to be selected in order to achieve the required flow rate of the drive.



Closed cooling circuit with water-heat exchange

In this system the internal cooling circuit of the inverter is connected to the external cooling circuit via a water/water heat exchanger. The marginally higher installation costs are compensated by the advantage of a nearly maintenance-free and especially reliable cooling system.

The low temperature level of the internal cooling circuit allows also serial connection of an air/water heat exchanger for cooling the enclosure air.

Braking unit

The use of a braking unit is required when more power is returned to the DC link during the braking procedure than the losses in the motor and inverter amount to or the application requires very short braking times.

The braking unit (internally or as an external option) is controlled and monitored by the ATV71Q. If the DC link voltage exceeds an adjustable value due to a braking procedure, an external braking resistor is switched into the DC link as a consumer. The braking resistor converts the power incurred into heat and thus prevents a further rising of the DC link voltage and thus a shut-down with overvoltage.

CAUTION

OVERLOAD OF THE BRAKING RESISTOR

Ensure for protection of the braking resistor that the correct data of the resistor are set at the inverter.

If the braking resistor does not match the overload characteristic to be used or the local regulations require an additional protective device, a thermal relay should be integrated into the mains disconnection mechanism.


The frequency inverters ATV71QD90N4 … C13N4 and ATV71QC11Y … C16Y have a built-in braking transistor. It is thus only necessary to connect an external braking resistor BR and to activate the braking function.

In case of the inverters ATV71QC16N4 … C50N4 and ATV71QC20Y … C63Y the braking unit is designed as an external option. It is supplied, controlled and monitored by the inverter as if it were integrated. An operation without an inverter or on a device other than the allocated one is thus not possible.

Commissioning

DANGER


Read the safety notes in chapter "Safety informations", page 7 completely and carefully before commissioning.


Proceeding

Check of power wiring

•

Is the mains supply connected to the terminals L1 / L2 / L3?

•

Check the external fan supply. For ATV71Q ●●● Y it has to be connected to terminals R0 / S0 / T0!

(See also chapter " External fan supply at ATV71Q ●●● Y ", page 46)

•

Check whether the mains fuses correspond to the table in chapter "Fuses", page 14.

• Does the length of the motor cable correspond with the allowed limits (see data sheet on www.schneiderelectric.com) and is a motor choke integrated, if required?

Checking the cooling water circuit

(See chapter "Remarks for cooling", page 74 for further information.)

•

Check whether the frequency inverter is integrated into the cooling system correctly.

•

Check whether the inlet and the return are correctly connected.

•

Check the whole cooling circuit for leak-tightness.

•

Fill and de-aerate the cooling circuit.

• The static operating pressure must be between 1.5 and 2.5 bar.

Check the EMC measures

•

Does the setting of the built-in EMC-filter correspond to the mains situation (TT, TN or IT, Corner

Grounded)? See also chapter "Nongrounded mains", page 16.

•

Has the screen of the motor cable a well HF connection on the motor and inverter side?

•

Are the low-level control wires (also the logic inputs) screened (shielded) and layed separately from the motor cables?

•

The frequency inverter (enclosure) requires a large surface connection to ground in order to keep the permitted interference limits.

Power up the device without run command

•

Ensure that the input PWR (POWER REMOVAL) is deactivated (state 0) to avoid an unintended start.

• Check the line voltage and turn it on.

•

Perform a check measurement:

•

Are the three phase voltages available and are they symmetrical?

(observe the regulation "Work on Live Equipment")

•

Check the control according to the delivered circuit diagrams and put it into operation.
