OUTLINE

Pre-operation instructions

1.1 Pre-operation instructions

Incorrect handling may cause the equipment to operate improperly or reduce its life considerably. Also, incorrect handling may

damage the FR-XC series converter and the inverter. Please handle the unit properly in accordance with the information on

each section as well as the precautions and instructions of the Instruction Manual.

1.1.1 Features of FR-XC series converters

NOTE

• It is not a fault if noise comes from the dedicated reactor during regenerative driving of the converter (in other words, it is a

fault if noise comes despite the stop state of the converter by the Converter stop (SOF) signal).

• If needed, devise methods of reducing noise by modifying the enclosure in which the reactor is installed.

Common bus regeneration mode

Enables continuous regenerative operation at 100% torque. This mode

supports continuous regenerative operations including line operation.

When the converter is connected to multiple inverters, regeneration

energy from an inverter is used for the other inverters. (The FR-XC series

converter can be used as a common converter.) Excessive energy is

returned to the power supply, saving on the energy consumption.

Use the FR-XC series converter in combination with the FR-XCL,

dedicated stand-alone reactor (option).

FR-XCLPower supply

FR-XC

MotorInverter

NOTE

• Note that the applicable inverter capacity and current are different if using the FR-XC-(H)18.5K-PWM or FR-XC-(H)22K-PWM

converter with its harmonic suppression function disabled. (Refer to page 156.)

Power regeneration mode

For power driving, the converter section of inverter unit supplies power, and

for regenerative driving, the FR-XC series converter returns power to the

power supply. (The FR-XC series converter cannot be used as a common

converter.)

Since the capacity of power regeneration converter is selectable according to

the regenerative power, the compact and inexpensive power regeneration

converter is applicable when the regenerative power is smaller than the

inverter capacity.

Use the FR-XC series converter in combination with the FR-XCL, dedicated

stand-alone reactor (option).

NOTE

• When installing the converter in a common bus system, do not use the converter in the power regeneration mode.

Harmonic suppression

(FR-XC-(H)22K or higher, FR-XC-(H)18.5K-PWM or higher)

The inverter unit has a converter section (rectifier circuit) and generates

power supply harmonics, which may affect the power generator, power

factor correction capacitor, etc. Power supply harmonics are different from

noise and leakage currents in source, frequency band and transmission

path. Power supply harmonics may be suppressed by using the FR-XC

series converter with its harmonic suppression function enabled, allowing

the compliance with the harmonic suppression guidelines issued by the

former Japanese Ministry of International Trade and Industry (currently the

Ministry of Economy, Trade and Industry). The FR-XC series converter with

its harmonic suppression function enabled is classified as the self-excitation

three-phase bridge circuit, and achieves K5 (the conversion factor) = 0. (It is assumed that the FR-XC series converter

generates no harmonics.)

Use the FR-XC series converter in combination with the FR-XCB, dedicated box-type reactor (option).

To enable the harmonic suppression function of the FR-XC-(H)22K or higher, switch to the common bus regeneration mode

and set Pr.416 = "1".

The harmonic suppression function is pre-enabled in the FR-XC-(H)[]K-PWM.

MotorInverter

NOTE

• The harmonic suppression function is not available in the power regeneration mode.

• FR-XC-(H)15K or lower does not have the harmonic suppression function.

• Note that the applicable inverter capacity and motor current are different depending on the harmonic suppression function

condition of the FR-XC-(H)22K or FR-XC-(H)30K converter. (Refer to page 156.)

• Power supply harmonic suppression effect

NOTE

• It does not mean that harmonic components completely disappear.

• When the load is light, harmonic suppression effect declines.

• When the power supply voltage is unstable, power harmonics flow in, making the harmonic current increase.

Temperature derating selection

By limiting the surrounding air temperature of the multifunction regeneration converter up to 40°C (the surrounding air

temperature of 40°C rating), rated current and applicable current can be increased. (Refer to page 40.)

ON Surrounding air temperature of 50°C rating OFF Surrounding air temperature of 40°C rating

4 For manufacturer setting. (Do not change from ON)

1.1.2 Function selection switch assembly (SW2)

The function can be changed by the function selection switches.

NOTE

• The changed switch setting is applied at the next power-ON or converter reset.

• If the switch 1 setting (the connection mode setting) does not match the actual wiring of the main circuit terminals, the

connection mode fault "E.T" occurs.

• By checking the parameter prevents unintended operation of multifunction regeneration converter caused by incorrect setting

of switch. (Refer to page 94.)

•Use Pr.416 Control method selection to enable or disable the harmonic suppression function. (Refer to page 40.)

1.1.3 Product checking and parts identification

1.1.4 Harmonic suppression guidelines in Japan

Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression

Guidelines was established to protect other consumers from these outgoing harmonic currents.

All capacity and all models of general-purpose inverter used by specific consumers are now covered by "the Harmonic

Suppression Guidelines for Consumers Who Receive High Voltage or Special High Voltage" (hereinafter referred to as

"the Specific Consumer Guidelines").

"Specific Consumer Guidelines"

This guideline sets forth the maximum harmonic currents outgoing from a high-voltage or especially high-voltage receiving

consumer who will install, add or renew harmonic generating equipment. If any of the maximum values is exceeded, this

guideline requires that consumer to take certain suppression measures.

• Calculation of equivalent capacity P0 of harmonic generating equipment

"Equivalent capacity" is the capacity of a 6-pulse converter converted from the capacity of consumer's harmonic

generating equipment and is calculated by the following equation. If the sum of equivalent capacities is higher than the

limit (refer to page 12), harmonics must be calculated by the equation in next subheading.

P0 = Σ (Ki × Pi) [kVA]

Ki: Conversion factor (Refer to page 12.) Pi: Rated capacity of harmonic generating equipment i: Number indicating the conversion circuit type

∗1 [kVA]

∗1 Rated capacity: Determined by the capacity of the

applied motor and found in the following table. The rated capacity used here is used to calculate the generated harmonic amount and is different from the power supply capacity required for actual inverter drive.

• Calculation of outgoing harmonic currents

Outgoing harmonic currents = fundamental wave current (value converted from received power voltage) × operation

ratio × harmonic contents

• Operation ratio: actual load factor × operation time ratio during 30 minutes

• Harmonic contents: Refer to the list of the harmonic contents.

Item Description

Install an AC reactor (FR-HAL) on the AC side of the inverter or a DC reactor (FR-HEL) on its DC side, or install both to suppress outgoing harmonic currents. The multifunction regeneration converter with harmonic suppression enabled switches the converter section ON/OFF to reshape an input current waveform into a sine wave, greatly suppressing harmonics. Use the FR-XC series converter with the FR-XCB box-type reactor.

When used with a reactor connected in series, the power factor improving correction capacitor can absorb harmonic currents.

Use two transformers and establish connections with a phase angle difference of 30° (the wye to delta connection or the delta to delta connection) to provide an effect corresponding to 12 pulses, reducing low-degree harmonic currents.

A capacitor and a reactor are used together to reduce impedances at specific frequencies. Harmonic currents are expected to be absorbed greatly by using this technique. This filter detects the current in a circuit generating a harmonic current and generates a harmonic current equivalent to a difference between that current and a fundamental wave current to suppress the harmonic current at the detection point. Harmonic currents are expected to be absorbed greatly by using this technique.

1.4 Precautions for selecting peripheral devices

1.4.1 Techniques and measures for electromagnetic

compatibility (EMC)

Some electromagnetic noises enter the converter to cause the converter malfunction, and others are radiated by the

converter to cause the peripheral devices to malfunction. (The former is called electromagnetic susceptibility (EMS) problem,

the latter is called electromagnetic interference (EMI) problem, and both is called electromagnetic compatibility (EMC)

problem.) Though the FR-XC series converter is designed to be immune to noises, it requires the following basic measures

and EMS measures as it handles low-level signals. Pay attention to the electromagnetic noises that could be generated by the

FR-XC series converter. If these noises cause peripheral devices to malfunction, EMI measures should be taken to suppress

noises. These techniques differ slightly depending on EMI paths.

Basic measures

• Do not run the power cables (I/O cables) and signal cables of the converter in parallel with each other and do not bundle

them.

• Use shielded twisted pair cables for the detector connecting and control signal cables and connect the sheathes of the

shielded cables to terminal SD.

• Ground (earth) the reactor, the converter, the inverter, etc. at one point. (Refer to page 66.)

EMS measures to reduce electromagnetic noises that enter the

When devices that generate many electromagnetic noises (which use magnetic contactors, electromagnetic brakes, many

relays, for example) are installed near the converter and the converter may malfunction due to electromagnetic noises, the

following countermeasures must be taken.

• Provide surge suppressors for devices that generate many electromagnetic noises to suppress electromagnetic noises.

• Install data line filters to signal cables.

• Ground (Earth) the shields of the detector connection and control signal cables with cable clamp metal.



Converter-generated noises are largely classified into those radiated by the converter itself and by the cables (I/O)

connected to its main circuit, those electromagnetically and electrostatically induced to the signal cables of the peripheral

devices close to the power cable connected to the converter main circuit, and those transmitted through the power cables.

Measure

When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the converter or when their signal cables are run near the converter, the devices may malfunction due to by air-propagated electromagnetic noises. The following measures must be taken:

• Install the easily affected devices as far away from the converter and the inverter as possible.

• Place the easily affected signal cables as far away from the converter and the inverter as possible.

• Do not run signal cables and power cables (converter I/O cables) in parallel with each other and do not bundle them.

• Install the FR-BLF line noise filter or the FR-BIF radio noise filter on the input side of the converter and install the FR-BLF on the output side of the inverter to suppress the radiated noise from the cables.

• Use shielded cables as signal cables and power cables, and run them in individual metal conduits, to produce further effects.

When the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction noises may be propagated to the signal cables to cause malfunction of the devices. The following measures must be taken:

• Install the easily affected devices as far away from the converter and the inverter as possible.

• Place the easily affected signal cables as far away from the converter and the inverter as possible.

• Do not run signal cables and power cables (converter I/O cables) in parallel with each other and do not bundle them.

• Use shielded cables as signal cables and power cables, and run them in individual metal conduits, to produce further effects.

When the power supplies of the peripheral devices are connected to the power supply of the converter in the same line, converter-generated noises may flow back through the power supply cables to cause malfunction of the devices. The following measures must be taken:

• Install the FR-BIF radio noise filter on the input side power cable of the converter.

• Install the FR-BLF line noise filters on the input side power cable of the converter and on the output side power cable of the inverter.

When a closed loop circuit is formed by connecting the peripheral devices wiring to the converter, leakage currents may flow through the earthing (grounding) cable of the converter to cause the devices to malfunction. In that case, disconnecting the earthing (grounding) cables from the devices may stop the malfunction of the devices.

EMI measure example

Power source for main circuit

For earthing (grounding) of the converter,

It is preferred that the inverter, the converter, and power cables are separated from sensor circuit by 30 cm or more (at least 10 cm).

Precautions for selecting peripheral devices

NOTE

• Install the earth leakage circuit breaker (ELB) on the input side of the converter.

• In the connection earthed-neutral system, the sensitivity current is blunt against a ground fault in the inverter output side.

Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes. (NEC

section 250, IEC 61140 class 1 and other applicable standards)

• Do not install the breaker on the output side of the inverter. Doing so may cause unnecessarily operations by harmonics even

if the effective value is within the rating, since the eddy current and hysteresis loss will increase, leading to temperature rise.

• The following models are included in the standard breakers: the BV-C1, BC-V, NVB, NV-L, NV-G2N, NV-G3NA, and NV-2F

earth leakage relay (except NV-ZHA) and the NV class earth leakage circuit breaker with AA neutral wire open-phase

INSTALLATION AND WIRING

Installation of the converter and enclosure design

2.3 Installation of the converter and enclosure

design

When designing or manufacturing an enclosure, determine the structure, size, and device layout of the enclosure by fully

considering the conditions such as heat generation of the contained devices and the operating environment.

The multifunction regeneration converter unit uses many semiconductor devices. To ensure higher reliability and long period

of operation, operate the converter in the ambient environment that completely satisfies the equipment specifications.

2.3.1 Converter installation environment

The following table lists the standard specifications of the installation environment for the multifunction regeneration converter.

Using the converter in an environment that does not satisfy the conditions deteriorates the performance, shortens the life, and

causes a failure. Refer to the following points, and take adequate measures.

Temperatur e

The permissible surrounding air temperature of the multifunction regeneration converter is -10 to +50°C (-10 to +40°C at the

40°C rating). Always operate the converter within this temperature range. Operation outside this range will considerably

shorten the service lives of the semiconductors, parts, capacitors and others. Take the following measures to keep the

surrounding air temperature of the converter within the specified range. (a) Measures against high temperature

• Use a forced ventilation system or similar cooling system. (Refer to page 31.)

• Install the enclosure in an air-conditioned electric chamber.

• Block direct sunlight.

• Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.

• Ventilate the area around the enclosure well. (b) Measures against low temperature

• Provide a space heater in the enclosure.

• Do not power OFF the converter. (Keep the start signal of the inverter OFF.) (c) Sudden temperature changes

• Select an installation place where temperature does not change suddenly.

• Avoid installing the converter near the air outlet of an air conditioner.

• If temperature changes are caused by opening/closing of a door, install the converter away from the door.

INSTALLATION AND WIRING

Installation of the converter and enclosure design

Humidity

Operate the multifunction regeneration converter within the ambient air humidity of usually 45 to 90% (up to 95% with circuit

board coating). Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low

humidity may cause a spatial electrical breakdown. The insulation distance defined in JEM 1103 "Control Equipment

Insulator" is humidity of 45 to 85%. (a) Measures against high humidity

• Make the enclosure enclosed, and provide it with a hygroscopic agent.

• Provide dry air into the enclosure from outside.

• Provide a space heater in the enclosure. (b) Measures against low humidity

Air with proper humidity can be blown into the enclosure from outside. Also when installing or inspecting the unit, discharge

your body (static electricity) beforehand, and keep your body away from the parts and patterns. (c) Measures against condensation

Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside air

temperature changes suddenly.

Condensation causes such faults as reduced insulation and corrosion.

Measures

• Take the measures against high humidity in (a).

• Do not power OFF the converter. (Keep the start signal of the inverter OFF.)

Dust, dirt, oil mist

Dust and dirt will cause such faults as poor contacts, reduced insulation and cooling effect due to the moisture-absorbed

accumulated dust and dirt, and in-enclosure temperature rise due to a clogged filter. In an atmosphere where conductive

powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time.

Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Measures

• Place the converter in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 31.)

• Purge air.

Pump clean air from outside to make the in-enclosure air pressure higher than the outside air pressure.

Corrosive gas, salt damage

If the converter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the

relays and switches will result in poor contact.

In such places, take the measures given in the previous paragraph.

Explosive, flammable gases

As the multifunction regeneration converter is non-explosion proof, it must be contained in an explosion-proof enclosure. In

places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally

complies with the guidelines and has passed the specified tests. This makes the enclosure itself expensive (including the test

charges). The best way is to avoid installation in such places and install the converter in a non-hazardous place.

High altitude

Use the multifunction regeneration converter at an altitude of within 2500 m. For use at an altitude above 1000 m, consider a

3% reduction in the rated current per 500 m increase in altitude.

If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric

strength.

INSTALLATION AND WIRING

Installation of the converter and enclosure design

Vibration, impact

The vibration resistance of the multifunction regeneration converter is up to 5.9 m/s2 at 10 to 55 Hz frequency and 1 mm

amplitude for the directions of X, Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and

cause poor contacts of connectors, even if those vibration and impacts are within the specified values.

Especially when impacts are applied repeatedly, caution must be taken because such impacts may break the installation feet.

Measures

• Provide the enclosure with rubber vibration isolators.

• Strengthen the structure to prevent the enclosure from resonance.

• Install the enclosure away from the sources of the vibration.

2.3.2 Cooling system types for converter enclosure

From the enclosure that contains the multifunction regeneration converter, the heat of the converter and other equipment

(inverter, transformers, reactors, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to

keep the in-enclosure temperature lower than the permissible temperatures of the in-enclosure equipment including the

converter.

The cooling systems are classified as follows in terms of the cooling calculation method.

(a) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)

(b) Cooling by heatsink (aluminum fin, etc.) (c) Cooling by ventilation (forced ventilation type, pipe ventilation type) (d) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

This system is low in cost and generally used, but the enclosure size increases as the converter capacity increases. This system is for relatively small capacities.

Being a totally enclosed type, this system is the most appropriate for hostile environment having dust, dirt, oil mist, etc. The enclosure size increases depending on the converter capacity.

This system has restrictions on the heatsink mounting position and area. This system is for relatively small capacities.

This system is for general indoor installation. This is appropriate for enclosure downsizing and cost reduction, and often used.

• For the models up to 30K converters or lower, cut the enclosure according to the dimensions shown on page 34.

• Install the converter on a strong surface securely with screws.

• Leave enough clearances and take cooling measures.

• Avoid places where the converter is subjected to direct sunlight, high temperature and high humidity.

• Install the converter on a nonflammable wall surface.

• When encasing multiple converters in an enclosure, install them in parallel as a cooling measure.

• For heat dissipation and maintenance, keep clearance between the converter and the other devices or enclosure surface.

The clearance below the converter is required as a wiring space, and the clearance above the converter is required as a

heat dissipation space.

• When designing or building an enclosure for the converter, carefully consider influencing factors such as heat generation of

the contained devices and the operating environment.

Arrangement of multiple converter/inverter units

When multiple converter/inverter units are placed in the

same enclosure, generally arrange them horizontally as

shown in the figure (a). When it is inevitable to arrange

them vertically to minimize space, take such measures as

to provide guides since heat generated in the units in

bottom row can increase the temperatures in the units in

top row, causing the failure of the units in top row.

When installing multiple units, fully take measures to

prevent the surrounding air temperature of the units from

being higher than the permissible value by providing

ventilation or increasing the enclosure size.

2.3.4 Protruding the heat sink through a panel

When encasing the multifunction regeneration converter to an enclosure, the heat generated in the enclosure can be greatly

reduced by protruding the heat sink of the multifunction regeneration converter. (The 30K converters or lower are designed to

be installed in an enclosure with its heatsink protruded through the panel.)

When installing the multifunction regeneration converter in a compact enclosure, etc., this installation method is

recommended.

Power regeneration mode

• Follow the following steps to confirm your converter selection and select the FR-HAL AC reactor.

1) Check the value of the potential regenerative capacity (kW) and the overload current rating of the converter you have

(on page 156). Confirm that you have selected the right converter with larger capacity than a motor capacity. Selection example: For a motor which can supply 10 kW regenerative power with an overload capacity of 120% (12 kW) for 60 seconds, the FR-XC-15K (15 kW converter) should be selected.

NOTE

• The new setting of the switch is applied at the next power-ON or converter reset.

• If the switch 1 setting (the connection mode setting) does not match the actual wiring of the main circuit terminals, the

connection mode fault "E.T" occurs.

2.5.3 Function enable/disable selection (Pr.416)

• Select the function status by setting Pr.416. Pr.416 setting Function

2.7.2 Control logic switchover

The control logic of input signals is initially set to the sink logic (SINK).

To change the control logic, the jumper connector next to the control circuit terminal block must be moved to the other

position.

The control logic of the multifunction regeneration converter and the inverter must be consistent. The converter does not

operate properly if the control logic is not consistent with each other.

(The output signals may be used in either the sink or source logic independently of the jumper connector position.)

Wiring method

• Wire insertion

Use crimp terminals and stripped wire for the control circuit wiring. For single wire, the stripped wire can be used without crimp terminal.

Connect the end of wires (crimp terminal or stranded wire) to the terminal block.

(1) Strip the signal wires as shown below. If too much of the wire is stripped, a short circuit may occur with neighboring wires.

If not enough of the wire is stripped, wires may become loose and fall out. Twist the stripped end of wires to prevent them

from fraying. Do not solder it.

Wire strip length

(2) Use appropriate crimp terminals (ferrules, blade terminals, etc.).

Insert wires to the crimp terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.

Check the condition of the crimp terminals after crimping. Do not use the crimp terminals of which the crimping is

inappropriate, or the face is damaged.

Common terminals of the control circuit (PC, SD, SE)

• Terminals PC, SD, and SE are all common terminals (0 V) for I/O signals and are isolated from each other. Do not earth

(ground) these terminals.

• Terminal SD is a common terminal for the contact input terminals (RES, SOF, and LOH). Use a shielded or twisted cable to

protect the terminal against malfunction caused by external noise. Connect the shielded cable to terminal SD (common

terminal). To connect an external power supply to terminal PC, however, connect the shield of the power supply cable to the

negative side of the external power supply. Do not directly earth (ground) the shield to the enclosure, etc. The open

collector circuit is isolated from the internal control circuit by photocoupler.

• Terminal SE is a common terminal for the open collector output terminals (RYA, RYB, and RSO). The contact input circuit is

isolated from the internal control circuit by photocoupler.

Signal inputs by contactless switches

The contact input terminals of the converter (RES, SOF, and LOH) can be

controlled using a transistor instead of a contact switch as follows.

+24 V

2.7.4 Wiring precautions

• It is recommended to use a cable of 0.3 to 1.25 mm2 for the connection to the control circuit terminals.

• The wiring length should be 30 m at the maximum.

However, the wiring length between the control circuit and the box-type reactor should be 5 m at the maximum (refer to

page 64).

• Use shielded or twisted cables for the control circuit terminals and run them away from the main and power circuits

(including the 200 V relay sequence circuit).

• Use two or more parallel micro-signal contacts or twin contacts to prevent a

contact faults when using contact inputs since the control circuit input signals

are micro-currents.

• Always apply a voltage to the fault output terminals (A, B, and C) via a relay

coil, lamp, etc.

When the protection circuit is activated, opening of the electromagnetic contactor

(MC) on the input side of the converter results in power loss in the control circuit of

the converter, disabling the fault output signal retention. To retain the fault signal,

add the node points joined to the control circuit power supply terminals R1/L11 and

S1/L21 on the MC power cable. Do not connect the power cable to incorrect

terminals. Doing so may damage the converter.

Earthing (Grounding) precautions

2.9 Earthing (Grounding) precautions

• Always earth (ground) the multifunction regeneration converter and the dedicated reactor FR-XCL or FR-XCB.

Purpose of earthing (grounding)

Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use.

An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an

insulating material that can shut off a leakage current completely, and actually, a slight current flows into the case. The

purpose of earthing (grounding) the case of an electrical apparatus is to prevent operators from getting an electric shock from

this leakage current when touching it.

To avoid the influence of external noises, the earthing (grounding) is important to EMI-sensitive equipment that handle low-

level signals or operate very fast such as audio equipment, sensors, computers.

Earthing (grounding) system to be established

As described previously, the purpose of earthing (grounding) is roughly classified into the electrical shock prevention and the

prevention of malfunction due to the influence of electromagnetic noise. These two purposes should be clearly distinguished.

Leakage currents containing many high frequency components flow into the earthing (grounding) cables of the converter.

When any other devices (EMI-sensitive devices) are earthed (grounded) nearby, the appropriate earth (ground) system must

be established as follows to prevent malfunction of such EMI-sensitive devices due to the leakage current from the converter,

inverter, or reactor.

• Make the separate earth (ground) connection (I) for the converter, inverter, and reactor away from other EMI-sensitive

devices wherever possible.

Establishing adequate common (single-point) earth (ground) system (II) shown in the following figure is allowed only in

cases where the separate earth (ground) system (I) is not feasible. Do not make inadequate common (single-point) earth

(ground) connection (III).

In a high building, it may be effective to use its iron structure frames as earthing (grounding) electrode for EMI prevention in

order to separate from the earth (ground) system for electric shock prevention.

• Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes (NEC

section 250, IEC 61140 class 1 and other applicable standards).

• Use the thickest possible earthing (grounding) cable. The size of the earthing (grounding) cable should be the same or

larger than the one indicated in the table on page 43.

• The earthing (grounding) point should be as close as possible to the converter, and the earth (ground) cable length should

be as short as possible.

• Run the earthing (grounding) cable as far away as possible from the I/O wiring of the EMI-sensitive devices, and run them

in parallel in the minimum distance.

Earthing (grounding) of the FR-XCL reactor

• The FR-XCL reactor is usually earthed (grounded) by being mounted securely on a panel of the enclosure. If it is not well

earthed (grounded) by being mounted on a panel of the enclosure, remove varnish from a mounting hole and make an

earthing (grounding) connection from the hole.

(For the location of the mounting hole whose varnish should be removed, refer to the outline dimensions on page 165.)

• For earthing (grounding) of the reactor, use the same gauge earthing (grounding) cable as that for the converter (refer to

page 43).

Make the separate earth (ground) connection for the converter, inverter, and reactor wherever possible.

The earthing (grounding) cable should be as close as possible to the power cables, and all these cables should be in parallel.

The converter and the dedicated reactor are allowed to have the common (single-point) earth (ground) system (unless the reactor is earthed (grounded) by being mounted on a panel of the enclosure).

If the inverter and the converter are installed far apart and the main circuit cables between them (P to P and N to N) are too long to store in an enclosure, the inverter earthing (grounding) cable is allowed to be connected to the converter and run as close as possible to the main circuit cables in parallel. When the main circuit cables are short enough to store in an enclosure, the inverter is allowed to join in the common (single-point) earth (ground) connection (c).

The motor earthing (grounding) cable is allowed be connected to the inverter earth (ground) terminal.

Description

2.10 Connection of the converter and the

multiple inverters

2.10.1 Connection in common bus regeneration mode

When the multifunction regeneration converter is used in common bus regeneration mode, multiple inverters can be connected to the converter. (The allowable number or permissible total capacity of inverters to be connected differs according to the converter capacity and the harmonic suppression function condition. Refer to page 156.) Select the converter so that the total capacity of the connected inverters must not exceed the applicable inverter capacity.

• For the multiple inverter connection, place the higher capacity inverter in the lower number axis.

• Junction terminals and cross wiring may be required for the wiring of the multiple inverters. For the gauge of cable used

between the two junction terminals, refer to the descriptions in the following figure. Total capacity of higher-number axis

inverters must be considered for the cable selection.

• It is recommended to install a fuse on each inverter power cable used between the inverter and the junction terminal, as

shown in the following figure. Select a fuse according to the motor capacity. (Refer to page 19.)

When using a motor whose capacity is smaller than the inverter capacity by two ranks or more, select the fuse with the

capacity that is one rank lower than the inverter capacity.

• Keep the wiring length (total length of cables) of each main circuit terminal (P/+ or N/-) between the converter and each

inverter within 5 m or less when converter's harmonic suppression function is disabled or within 50 m or less when the

function is enabled.

• The total wiring length between terminals P/+ or terminals N/- on the converter and connected inverters should not exceed

the length shown in the following table.

When this signal turns ON, the converter operation stops. The converter operation for this signal can be changed by using Pr.8.

The signal is input from the external thermal relay. When this signal turns ON, the fault E.H occurs and the converter output is shut off. The converter operation for this signal can be changed by using Pr.9.

The signal is input from the box-type reactor. If the converter with harmonic suppression function enabled starts operation while the LOH signal is not assigned to any of the input terminals or if the cooling fan in the box-type reactor connected the converter stops due to a failure or reduces speed, the fault E.FT1 occurs and the converter output is shut off. If the LOH signal is input to the converter with harmonic suppression function disabled, the fault E.FT1 occurs and the converter output is shut off.

NOTE

• One function can be assigned to the different terminals. In this case, the logic of terminal input is OR.

• When the terminal assignment is changed by changing the initial setting of Pr.3, Pr.4, and Pr.7 (Input terminal function

9999 The same setting in Pr.22 is applied.

Set the current limit where the current limit operation starts (during regenerative driving).

Set the proportional gain for the voltage control. Increasing the setting value reduces the DC voltage fluctuation caused by external disturbance.

Set the integral gain for the voltage control. Increasing the setting value shortens the recovery time from the DC voltage fluctuation caused by external disturbance.

Description

Adjusting DC voltage fluctuation (Pr.80 and Pr.81)

• Adjust the fluctuation range of the DC voltage by setting Pr.80.

Increasing the setting value reduces the DC voltage fluctuation caused by external disturbance.

• Adjust the recovery time to the commanded value at a fluctuation of DC voltage by setting Pr.81.

Increasing the setting value shortens the recovery time from the DC voltage fluctuation caused by external disturbance.

NOTE

• Setting Pr.80 too large makes the operation unstable.

• Setting only Pr.81 makes the operation unstable.

Setting the current limit level (Pr.22 and Pr.23)

• Limit the output current not to exceed the specified value.

Set the current limit level by using Pr.22.

Current limit level at the regenerative operation can be individually set by setting a value other than "9999" to Pr.23

Set the current limits as a percentage (set current limit ratios) with 100 being equal to the converter rated current in Pr.22

and Pr.23.

• The OL signal is output when output currents are limited by the current limit level (when the current limit function is active).

NOTE

• When the output current reaches the current limit level, DC voltage decreases during power driving or increases during

regeneration.

PARAMETERS

Parameter details

• When the protective function is activated after retries are attempted consecutively more than the number of times set in

Pr.67, the Retry count excess fault (E.K) occurs and the converter output is shut off. (Refer to the figure of retry failure

example.)

• Use Pr.68 to set the waiting time from when the converter output has been shut off until a retry is made in the range of 0 to

600 seconds.

• The cumulative count in Pr.69 increases by 1 when a retry is successful. Retry is regarded as successful when normal

operation continues without a fault for the Pr.68 setting multiplied by four or longer (6 seconds at the shortest).

(When retry is successful, the cumulative number of retry failures is cleared.)

• Writing "0" in Pr.69 clears the retry counter.

During a retry, the RTY signal is ON. For the RTY signal, set "11 (positive logic)" or "111 (negative logic)" in any of Pr.11,

Pr.12, and Pr.16 (Output terminal function selection) to assign the function.

NOTE

• Changing the terminal assignment using Pr.11, Pr.12, or Pr.16 (Output terminal function selection) may affect the other

functions. Set parameters after confirming the function of each terminal.

• Faults which trigger the retry operation can be selected with Pr.65. The faults not described in the following table do not

enable the retry function. (For the fault details, refer to page 134.)

NOTE

• Only the first fault is recorded in the fault history during retries.

• If a fault that does not trigger the retry operation occurs during retries, the converter output is shut off with the fault indication

after the retries finish.

• The fault reset by the retry function does not reset the accumulated data such as the electronic thermal relay function data.

(The reset result is different from the power-ON reset.)

CAUTION

 When setting the retry function enabled, stay away from the motor and machine. The motor and machine will start suddenly (after the

reset time has elapsed) after the shutoff.
