DC voltage is applied to the motor for 1s at powering off. Never touch the motor terminal, etc. right after powering off to prevent an electric shock.

when the inverter is running, do not

2. Fire Prevention

CAUTION



Install the inverter on a nonflammable wall without holes (so that nobody can touch the inverter heatsink on the rear side, etc.). Mounting it to or near flammable material can cause a fire.

 If the inverter has become faulty, switch off the inverter

power. A continuous flow of large current could cause a fire.

 When using a brake resistor, make up a sequence that will

turn off power when an alarm signal is output. Otherwise, the brake resistor may excessively overheat due to damage of the brake transistor and such, causing a fire.

 Do not connect a resistor directly to the DC terminals P/+

and N/-. This could cause a fire.

A-1

3.Injury Prevention

CAUTION

 Transport the product using the correct method that

corresponds to the weight. Failure to observe this could

lead to injuries.

 Do not stack the inverter boxes higher than the number

recommended.

 Ensure that installation position and material can

withstand the weight of the inverter. Install according to

the information in the instruction manual.

 Do not install or operate the inverter if it is damaged or

has parts missing.

 When carrying the inverter, do not hold it by the front

cover or setting dial; it may fall off or fail.

 Do not stand or rest heavy objects on the product.

 Check the inverter mounting orientation is correct.

 Prevent other conductive bodies such as screws and

metal fragments or other flammable substance such as oil

from entering the inverter.

 As the inverter is a precision instrument, do not drop or

subject it to impact.

 Use the inverter under the following environmental

conditions: Otherwise, the inverter may be damaged.

Surrounding air temperature

(2) Wiring

CAUTION

 Do not install a power factor correction capacitor or surge

suppressor/capacitor type filter on the inverter output

side. These devices on the inverter output side may be

overheated or burn out.

 The connection orientation of the output cables U, V, W to

the motor will affect the direction of rotation of the motor.

(3) Trial run

CAUTION

 Before starting operation, confirm and adjust the

parameters. A failure to do so may cause some machines

to make unexpected motions.

(4) Usage

 When you have chosen the retry function, stay away from

the equipment as it will restart suddenly after trip.

 Since pressing key may not stop output depending

on the function setting status, provide a circuit and switch

separately to make an emergency stop (power off,

mechanical brake operation for emergency stop, etc).

 Make sure that the start signal is off before resetting the

inverter alarm. A failure to do so may restart the motor

suddenly.

The load used should be a three-phase induction motor only.



Connection of any other electrical equipment to the

inverter output may damage the equipment.

 Do not modify the equipment.

Do not perform parts removal which is not instructed in this



manual. Doing so may lead to fault or damage of the product.

CAUTION



The electronic thermal relay function does not guarantee

protection of the motor from overheating. It is recommended

to install both an external thermal and PTC thermistor for

overheat protection.

 Do not use a magnetic contactor on the inverter input for

frequent starting/stopping of the inverter. Otherwise, the

life of the inverter decreases.

 Use a noise filter to reduce the effect of electromagnetic

interference. Otherwise nearby electronic equipment may

be affected.

 Take measures to suppress harmonics. Otherwise power

supply harmonics from the inverter may heat/damage the

power factor correction capacitor and generator.

 When a 400V class motor is inverter-driven, please use an

insulation-enhanced motor or measures taken to

suppress surge voltages. Surge voltages attributable to

the wiring constants may occur at the motor terminals,

deteriorating the insulation of the motor.

 When parameter clear or all parameter clear is performed,

reset the required parameters before starting operations.

Each parameter returns to the initial value.

 The inverter can be easily set for high-speed operation.

Before changing its setting, fully examine the

performances of the motor and machine.

 In addition to the inverter’s holding function, install a

holding device to ensure safety.

 Before running an inverter which had been stored for a

long period, always perform inspection and test

operation.

 For prevention of damage due to static electricity, touch

nearby metal before touching this product to eliminate

static electricity from your body.

A-2

(5) Emergency stop

CAUTION

 Provide a safety backup such as an emergency brake

which will prevent the machine and equipment from

hazardous conditions if the inverter fails.

 When the breaker on the inverter input side trips, check

for the wiring fault (short circuit), damage to internal parts

of the inverter, etc. Identify the cause of the trip, then

remove the cause and power on the breaker.

 When any protective function is activated, take the

appropriate corrective action, then reset the inverter, and

resume operation.

(6) Maintenance, inspection and parts replacement

CAUTION

 Do not carry out a megger (insulation resistance) test on

the control circuit of the inverter. It will cause a failure.

(7) Disposal

CAUTION

 Treat as industrial waste.

1.2 Inverter and peripheral devices

Inverter and peripheral devices

AC reactor (FR-HAL)

Three-phase AC power supply

Use within the permissible power supply specifications of the inverter. To ensure safety, use a moulded case circuit breaker, earth leakage circuit breaker or magnetic contactor to switch power ON/OFF.

(Refer to page 281)

Moulded case circuit breaker (MCCB) or earth leakage circuit breaker (ELB), fuse

The breaker must be selected carefully since an in-rush current flows in the inverter at power on.

(Refer to page 4)

Magnetic contactor (MC)

Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shorten.

(Refer to page 44)

Reactor (FR-HAL, FR-HEL option)

Reactors (option) must be used when power harmonics measures are taken, the power factor is to be improved or the inverter is installed near a large power supply system (500kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. Remove the jumpers across terminals P/+ and P1 to connect the DC reactor.

DC reactor (FR-HEL)

Noise filter (FR-BSF01, FR-BLF)

Install a noise filter to reduce the electromagnetic noise generated from the inverter. Effective in the range from about 1MHz to 10MHz. When more wires are passed through, a more effective result can be obtained. A wire should be wound four turns or more.

P/+

Parameter unit (FR-PU07)

By connecting the connection cable (FR-CB2) to the PU connector, operation can be performed from FR-PU07.

Devices connected to the output

Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the output side of the inverter. When installing a moulded case circuit breaker on the output side of the inverter, contact each manufacturer for selection of the moulded case circuit breaker.

Earth (Ground)

To prevent an electric shock, always earth (ground) the motor and inverter. For reduction of induction noise from the power line of the inverter, it is recommended to wire the earth (ground) cable by returning it to the earth (ground) terminal of the inverter.

NOTE



The life of the inverter is influenced by surrounding air temperature. The surrounding air temperature should be as low as possible within the permissible range. This must be noted especially when the inverter is installed in an enclosure.

 Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully away from the main

circuit to protect them from noise. (Refer to page 14)

 Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output

side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are connected, immediately remove them.

 Electromagnetic wave interference

The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional capacitor type filter (for use in the input side only) or FR-BSF01 or FR-BLF common mode filter to minimize interference.

 Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.

Installation of the inverter and enclosure design

1.4 Installation of the inverter and enclosure design

When an inverter panel is to be designed and manufactured, heat generated by contained equipment, etc., the environment of an operating place, and others must be fully considered to determine the panel structure, size and equipment layout. The inverter unit uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the ambient environment that completely satisfies the equipment specifications.

1.4.1 Inverter installation environment

As the inverter installation environment should satisfy the standard specifications indicated in the following table, operation in any place that does not meet these conditions not only deteriorates the performance and life of the inverter, but also causes a failure. Refer to the following points and take adequate measures.

Environmental standard specifications of inverter

(1) Temperature

The permissible surrounding air temperature of the inverter is between -10 and +50°C inverter 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 so that the surrounding air temperature of the inverter falls within the specified range.

1) Measures against high temperature

 Use a forced ventilation system or similar cooling system. (Refer to page 10)

 Install the panel in an air-conditioned electrical 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 panel well.

°C (14°F to 122°F)(non-freezing)

or less

(14°F to 122°F). Always operate the

2) Measures against low temperature

 Provide a space heater in the enclosure.

 Do not power off the inverter. (Keep the start signal of the inverter off.)

3) Sudden temperature changes

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

 Avoid installing the inverter near the air outlet of an air conditioner.

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

(2) Humidity

Normally operate the inverter within the 45 to 90% range of the ambient humidity. Too high humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may produce a spatial electrical breakdown. The insulation distance specified in JEM1103 "Control Equipment Insulator" is defined as humidity 45 to 85%.

1) Measures against high humidity

 Make the panel enclosed, and provide it with a hygroscopic agent.

 Take dry air into the enclosure from outside.

 Provide a space heater in the enclosure.

2) Measures against low humidity

What is important in fitting or inspection of the unit in this status is to discharge your body (static electricity)

beforehand and keep your body from contact with the parts and patterns, besides blowing air of proper humidity into

the enclosure from outside.

3) 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.

 Take the measures against high humidity in 1).

 Do not power off the inverter. (Keep the start signal of the inverter off.)

Installation of the inverter and enclosure design

(3) Dust, dirt, oil mist

Dust and dirt will cause such faults as poor contact of contact points, reduced insulation or reduced cooling effect due to

moisture absorption of accumulated dust and dirt, and in-enclosure temperature rise due to clogged filter. In the 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.

Countermeasures

 Place in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 10)

 Purge air.

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

(4) Corrosive gas, salt damage

If the inverter 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 Section 3.

(5) Explosive, flammable gases

As the inverter 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 inverter in a non-hazardous place.

(6) Highland

Use the inverter at the altitude of within 1000m (3280.80 feet). 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.

Maximum 1000m (3280.80feet) above sea level for standard operation. After that derate by 3% for every extra 500m

(1640.40feet) up to 2500m (8202feet) (91%).

(7) Vibration, impact

The vibration resistance of the inverter is up to 5.9m/s2 at 10 to 55Hz frequency and 1mm amplitude. Vibration or impact, if

less than the specified value, applied for a long time may make the mechanism loose or cause poor contact to the connectors.

Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to break.

Countermeasures

 Provide the panel with rubber vibration isolators.

 Strengthen the structure to prevent the enclosure from resonance.

 Install the enclosure away from sources of vibration.

Installation of the inverter and enclosure design

1.4.2 Cooling system types for inverter enclosure

From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, 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-panel equipment including the inverter.

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

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

2) Cooling by heat sink (aluminum fin, etc.)

3) Cooling by ventilation (forced ventilation type, pipe ventilation type)

4) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

(3) Inverter mounting orientation

Mount the inverter on a wall as specified. Do not mount it horizontally or any other way.

(4) Above inverter

Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be

heat resistant.

Installation of the inverter and enclosure design

(5) Arrangement of multiple inverters

When multiple inverters are placed in the same

enclosure, generally arrange them horizontally as shown

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

them vertically to minimize space, take such measures as

to provide guides since heat from the bottom inverters

can increase the temperatures in the top inverters,

causing inverter failures.

When mounting multiple inverters, fully take caution not

to make the surrounding air temperature of the inverter

higher than the permissible value by providing ventilation

and increasing the enclosure size.

(6) Arrangement of ventilation fan and inverter

Heat generated in the inverter is blown up from the bottom of

the unit as warm air by the cooling fan. When installing a

ventilation fan for that heat, determine the place of ventilation

fan installation after fully considering an air flow. (Air passes

through areas of low resistance. Make an airway and airflow

plates to expose the inverter to cool air.)

NOTE

 Tighten the terminal screw to the specified torque. A screw that has been tightened too loosely can cause a short

circuit or malfunction. A screw that has been tightened too tightly can cause a short circuit or malfunction due to the

unit breakage.

 Use crimping terminals with insulation sleeve to wire the power supply and motor.

WIRING

The line voltage drop can be calculated by the following formula:

line voltage drop [V]=

3 × wire resistance[mΩ/m] × wiring distance[m] × current[A]

1000

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque

reduction) in the low speed range.

Main circuit terminal specifications

(2) Earthing (Grounding) precautions

 Always earth (ground) the motor and inverter.

1) 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 flow into the case.

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

shock from this leakage current when touching it.

To avoid the influence of external noises, this earthing (grounding) is important to audio equipment, sensors, computers

and other apparatuses that handle low-level signals or operate very fast.

2) Earthing (grounding) methods and earthing (grounding) work

As described previously, earthing (grounding) is roughly classified into an electrical shock prevention type and a noise-

affected malfunction prevention type. Therefore, these two types should be discriminated clearly, and the following

work must be done to prevent the leakage current having the inverter's high frequency components from entering the

malfunction prevention type earthing (grounding):

(a)Where possible, use independent earthing (grounding) for the inverter. If independent earthing (grounding) (I) is

impossible, use joint earthing (grounding) (II) where the inverter is connected with the other equipment at an earthing (grounding) point. Joint earthing (grounding) as in (III) must be avoided as the inverter is connected with the other equipment by a common earth (ground) cable. Also a leakage current including many high frequency components flows in the earth (ground) cables of the inverter and inverter-driven motor. Therefore, they must use the independent earthing (grounding) method and be separated from the earthing (grounding) of equipment sensitive to the aforementioned noises. In a tall building, it will be a good policy to use the noise malfunction prevention type earthing (grounding) with steel frames and carry out electric shock prevention type earthing (grounding) in the independent earthing (grounding) method.

(b)This inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and

local safety regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards). Use an neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard.

(c)Use the thickest possible earth (ground) cable. The earth (ground) cable should be of not less than the size indicated

in the table on the previous page 17.

(d)The earthing (grounding) point should be as near as possible to the inverter, and the earth (ground) cable length

should be as short as possible.

(e)Run the earth (ground) cable as far away as possible from the I/O wiring of equipment sensitive to noises and run

them in parallel in the minimum distance.

When driving a 400V class motor by the inverter, surge voltages attributable to the wiring constants may occur at the

motor terminals, deteriorating the insulation of the motor.(Refer to page 83)

NOTE

 Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray

capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit function, or stall prevention function or a malfunction or fault of the equipment connected on the inverter output side. If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention function occurs, increase the stall level. (Refer to page 79 for Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention

operation selection )

 Refer to page 148 for details of Pr. 72 PWM frequency selection. Refer to the manual of the option for details of surge

Control circuit specifications

(3) Control circuit common terminals (SD, 5, SE)

Terminals SD, SE and 5 are common terminals for I/O signals.(All common terminals are isolated from each other.) Do not

earth them. Avoid connecting the terminal SD and 5 and the terminal SE and 5.

Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL). The open collector circuit is

isolated from the internal control circuit by photocoupler

Terminal 5 is a common terminal for the frequency setting signals (terminals 2 or 4) and analog signal output (AM). It should

be protected from external noise using a shielded or twisted cable.

Terminal SE is a common terminal for the open collector output terminal (RUN). The contact input circuit is isolated from the

internal control circuit by photocoupler.

(4) Signal inputs by contactless switches

The contacted input terminals of the inverter (STF, STR,

RH, RM, RL) can be controlled using a transistor

instead of a contacted switch as shown on the right.

2.3.4 Wiring instructions

1) Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power

circuits (including the 200V relay sequence circuit).

2) Use two or more parallel micro-signal contacts or twin contacts to prevent

contact faults when using contact inputs since the control circuit input signals are micro-currents.

3) Do not apply a voltage to the contact input terminals (e.g. STF) of the control

circuit.

4) Always apply a voltage to the fault output terminals (A, B, C) via a relay coil, lamp, etc.

5) It is recommended to use the cables of 0.3mm

If the cable gauge is 1.25mm2 or more, the front cover may be lifted when there are many cables running or the cables are run improperly, resulting in a fall off of the front cover.

6) The maximum wiring length should be 30m (98.43feet).

EMC and leakage currents

3.1 EMC and leakage currents

3.1.1 Leakage currents and countermeasures

Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current

flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the

increased carrier frequency of the inverter will increase the leakage current. Therefore, take the following measures. Select

the earth leakage current breaker according to its rated sensitivity current, independently of the carrier frequency setting.

(1) To-earth (ground) leakage currents

Leakage currents may flow not only into the inverter's own line but also into the other lines through the earth (ground) cable,

etc. These leakage currents may operate earth (ground) leakage circuit breakers and earth leakage relays unnecessarily.

Suppression technique

 If the carrier frequency setting is high, decrease the Pr. 72 PWM frequency selection setting.

Note that motor noise increases. Selecting Pr. 240 Soft-PWM operation selection makes the sound inoffensive.

 By using earth leakage circuit breakers designed for harmonic and surge suppression in the inverter's own line and other

line, operation can be performed with the carrier frequency kept high (with low noise).

To-earth (ground) leakage currents

 Take caution as long wiring will increase the leakage current. Decreasing the carrier frequency of the inverter reduces the

leakage current.

 Increasig the motor capacity increases the leakage current. The leakage current of the 400V class is larger than that of

the 200V class.

(2) Line-to-line leakage currents

Harmonics of leakage currents flowing in static capacitances between the inverter output cables may operate the external

thermal relay unnecessarily. When the wiring length is long (50m (164.04feet) or more) for the 400V class small-capacity model

(FR-D740-160 or less), the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to

the rated motor current increases.

Note that motor noise increases. Selecting Pr. 240 Soft-PWM operation selection makes the sound inoffensive. To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor to directly detect motor temperature.

Installation and selection of moulded case circuit breaker

Install a moulded case circuit breaker (MCCB) on the power receiving side to protect the wiring of the inverter input side.

Select the MCCB according to the inverter input side power factor (which depends on the power supply voltage, output

frequency and load). Especially for a completely electromagnetic MCCB, one of a slightly large capacity must be selected

since its operation characteristic varies with harmonic currents. (Check it in the data of the corresponding breaker.) As an

earth leakage current breaker, use the Mitsubishi earth leakage current breaker designed for harmonics and surge

suppression.

and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards)

 When the breaker is installed on the output side of the inverter, it may be unnecessarily operated by harmonics even

if the effective value is less than the rating.

In this case, do not install the breaker since the eddy current and hysteresis loss will increase, leading to temperature

3.1.2 EMC measures

Some electromagnetic noises enter the inverter to malfunction it and others are radiated by the inverter to malfunction

peripheral devices. Though the inverter is designed to have high immunity performance, it handles low-level signals, so it

requires the following basic techniques. Also, since the inverter chops outputs at high carrier frequency, that could generate

electromagnetic noises. If these electromagnetic noises cause peripheral devices to malfunction, EMI measures should be

taken to suppress noises. These techniques differ slightly depending on EMI paths.

(1) Basic techniques

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

them.

 Use twisted shield cables for the detector connecting and control signal cables and connect the sheathes of the shield

cables to terminal SD.

 Earth (Ground) the inverter, motor, etc. at one point.

(2) Techniques to reduce electromagnetic noises that enter and malfunction the inverter (Immunity measures)

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

for example) are installed near the inverter and the inverter may be malfunctioned by electromagnetic noises, the following

measures must be taken:

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

 Fit data line filters (page 41) to signal cables.

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

(3) Techniques to reduce electromagnetic noises that are radiated by the inverter to malfunction peripheral devices (EMI

measures)

Inverter-generated electromagnetic noises are largely classified into those radiated by the cables connected to the inverter

and inverter main circuits (I/O), those electromagnetically and electrostatically induced to the signal cables of the peripheral

devices close to the main circuit power supply, and those transmitted through the power supply cables.

When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g.

cables are run near the inverter, the devices may be malfunctioned by air-propagated electromagnetic noises. The

following measures must be taken:

(1)(2)(3)

(4)(5)(6)

(7)

(8)

 Install easily affected devices as far away as possible from the inverter.

 Run easily affected signal cables as far away as possible from the inverter and its I/O cables.



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

 Insert common mode filters into I/O and capacitors between the input lines to suppress cable-radiated noises.



Use shield 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 malfunction the devices and the following measures must be taken:

 Install easily affected devices as far away as possible from the inverter.

 Run easily affected signal cables as far away as possible from the I/O cables of the inverter.



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

Use shield 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 inverter in the same line,

inverter-generated noises may flow back through the power supply cables to malfunction the devices and the

following measures must be taken:

 Install the common mode filter (FR-BLF, FR-BSF01) to the power cables (output cable) of the inverter. When a closed loop circuit is formed by connecting the peripheral device wiring to the inverter, leakage currents may

flow through the earth (ground) cable of the inverter to malfunction the device. In such a case, disconnection of the

earth (ground) cable of the device may cause the device to operate properly.

EMC and leakage currents

3.1.3 Power supply harmonics

The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power capacitor

etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission path.

Take the following countermeasure suppression techniques.

The differences between harmonics and RF noises are indicated below:

Item Harmonics Noise

Environment To-electric channel, power impedance To-space, distance, wiring path

Quantitative understanding Theoretical calculation possible Random occurrence, quantitative grasping difficult

Generated amount Nearly proportional to load capacity

Affected equipment immunity Specified in standard per equipment Different depending on maker's equipment specifications

Suppression example Provide reactor. Increase distance.

Suppression technique

The harmonic current generated from the inverter

to the input side differs according to various

conditions such as the wiring impedance, whether

a reactor is used or not, and output frequency and

output current on the load side. For the output frequency and output current, we

understand that they should be calculated in the

conditions under the rated load at the maximum

operating frequency.

overcurrent protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is

driven by the inverter. For power factor improvement, install a reactor on the inverter input side or in the DC circuit.

Installation of power factor improving reactor

3.2 Installation of power factor improving reactor

When the inverter is connected near a large-capacity power transformer (500kVA or more) or when a power capacitor is to be

switched over, an excessive peak current may flow in the power input circuit, damaging the converter circuit. To prevent this,

always install an optional reactor (FR-HAL, FR-HEL).

PRECAUTIONS FOR USE OF THE INVERTER

Power-off and magnetic contactor (MC)

3.3 Power-off and magnetic contactor (MC)

(1) Inverter input side magnetic contactor (MC)

On the inverter input side, it is recommended to provide an MC for the following purposes.

(Refer to page 4 for selection.)

1) To release the inverter from the power supply when the fault occurs or when the drive is not functioning (e.g. emergency

stop operation). When cycle operation or heavy-duty operation is performed with an optional brake resistor connected,

overheat and burnout of the discharging resistor can be prevented if a regenerative brake transistor is damaged due to

insufficient heat capacity of the discharging resistor and excess regenerative brake duty.

2) To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure

3) The control power supply for inverter is always running and consumes a little power. When stopping the inverter for an

extended period of time, powering off the inverter will save power slightly.

4) To separate the inverter from the power supply to ensure safe maintenance and inspection work.

The inverter's input side MC is used for the above purpose, select class JEM1038-AC3 MC for the inverter input side

current when making an emergency stop during normal operation.

REMARKS

Since repeated inrush currents at power on will shorten the life of the converter circuit (switching life is about 1,000,000 times.),

frequent starts and stops of the MC must be avoided. Turn on/off the inverter start controlling terminals (STF, STR) to run/stop the

inverter.

 Inverter start/stop circuit example

As shown on the left, always use the start signal (ON or OFF across terminals STF or STR-SD) to make a start or stop.

(2) Handling of inverter output side magnetic contactor

Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the

magnetic contactor is turned on while the inverter is operating, overcurrent protection of the inverter and such will activate.

When an MC is provided for switching to the commercial power supply, for example, switch it on/off after the inverter and

motor have stopped.

Inverter-driven 400V class motor

3.4 Inverter-driven 400V class motor

In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a

400V class motor, the surge voltage may deteriorate the insulation. When the 400V class motor is driven by the inverter,

consider the following measures:

Measures

It is recommended to take either of the following measures:

(1) Rectifying the motor insulation and limiting the PWM carrier frequency according to the wiring

length

For the 400V class motor, use an insulation-enhanced motor.

Specifically,

1) Specify the "400V class inverter-driven insulation-enhanced motor".

2) For the dedicated motor such as the constant-torque motor and low-vibration motor, use the "inverter-driven, dedicated

motor".

3) Set Pr. 72 PWM frequency selection as indicated below according to the wiring length

Wiring Length

50m (164.04feet) or less

Pr. 72 PWM frequency selection 15 (14.5kHz) or less 8 (8kHz) or less 2 (2kHz) or less

50m to 100m

(164.04feet to 328.09feet)

exceeding 100m

(328.09feet)

(2) Suppressing the surge voltage on the inverter side

Connect the surge voltage suppression filter (FR-ASF-H/FR-BMF-H) on the inverter output side.

NOTE

 For details of Pr. 72 PWM frequency selection, refer to page 148.

 For explanation of surge voltage suppression filter (FR-ASF-H/FR-BMF-H), refer to the manual of each option

PRECAUTIONS FOR USE OF THE INVERTER

Precautions for use of the inverter

3.5 Precautions for use of the inverter

The FR-D700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may

shorten the product life or damage the product.

Before starting operation, always recheck the following items.

(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.

(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.

(3) After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.

When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the

inverter.

(4) Use cables of the size to make a voltage drop 2% maximum.

If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque

to decrease especially at the output of a low frequency.

Refer to page 17 for the recommended wire sizes.

(5) The overall wiring length should be 500m (1640.42feet) maximum.

Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to

the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity

of the wiring. Therefore, note the overall wiring length. (Refer to page 19)

(6) Electromagnetic wave interference

The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the

communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF optional capacitor

type filter (for use in the input side only) or FR-BSF01 or FR-BLF common mode filter to minimize interference.

(7) Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the inverter output side.

This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices are

connected, immediately remove them. (When using capacitor type filter (FR-BIF) for single-phase power supply

specification, make sure of secure insulation of T/L3-phase, and connect to the input side of the inverter.)

(8) For some short time after the power is switched off, a high voltage remains in the smoothing capacitor. When accessing

the inverter for inspection, wait for at least 10 minutes after the power supply has been switched off, and then make sure

that the voltage across the main circuit terminals P/+ and N/- of the inverter is not more than 30VDC using a tester, etc.

The capacitor is charged with high voltage for some time after power off and it is dangerous.

(9) A short circuit or earth (ground) fault on the inverter output side may damage the inverter modules.

 Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by

peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation

resistance may damage the inverter modules.

 Fully check the to-earth (ground) insulation and phase to phase insulation of the inverter output side before power-on.

Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.

(10) Do not use the inverter input side magnetic contactor to start/stop the inverter.

Always use the start signal (turn on/off STF and STR signals) to start/stop the inverter. (Refer to page 44)

(11) Across P/+ and PR terminals, connect only an external regenerative brake discharging resistor.

Do not connect a mechanical brake.

The brake resistor can not be connected to the FR-D720-008 and 014 and FR-D720S-008 and 014. Never short

between terminals P/+ and PR.

Precautions for use of the inverter

(12) Do not apply a voltage higher than the permissible voltage to the inverter I/O signal circuits.

Application of a voltage higher than the permissible voltage to the inverter I/O signal circuits or opposite polarity may

damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected

incorrectly to short terminals 10-5.

(13) Provide electrical and mechanical interlocks for MC1 and MC2

which are used for bypass operation. When the wiring is

incorrect and if there is a bypass operation circuit as shown

right, the inverter will be damaged due to arcs generated at the

time of switch-over or chattering caused by a sequence error.

(14) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the

inverter's input side and also make up a sequence which will not switch on the start signal.

If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the

power is restored.

(15) Instructions for overload operation

When performing operation of frequent start/stop of the inverter, rise/fall in the temperature of the transistor element of

the inverter will repeat due to a repeated flow of large current, shortening the life from thermal fatigue. Since thermal

fatigue is related to the amount of current, the life can be increased by reducing current at locked condition, starting

current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and

the inverter may not start. Therefore, choose the inverter which has enough allowance for current (up to 2 rank larger in

capacity).

(16) Make sure that the specifications and rating match the system requirements.

(17) When the motor speed is unstable, due to change in the frequency setting signal caused by electromagnetic noises from

the inverter, take the following measures while applying the motor speed by the analog signal.

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

 Run signal cables as far away as possible from power cables (inverter I/O cables).

 Use shield cables as signal cables.

 Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

PRECAUTIONS FOR USE OF THE INVERTER

Failsafe of the system which uses the inverter

3.6 Failsafe of the system which uses the inverter

When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal may not be output at an inverter

fault occurrence when the detection circuit or output circuit fails, etc. Although Mitsubishi assures best quality products,

provide an interlock which uses inverter status output signals to prevent accidents such as damage to machine when the

inverter fails for some reason and at the same time consider the system configuration where failsafe from outside the inverter,

without using the inverter, is enabled even if the inverter fails.

(1) Interlock method which uses the inverter status output signals

By combining the inverter status output signals to provide an interlock as shown below, an inverter alarm can be

detected.

1) Check by the inverter fault output signal

When the fault occurs and the inverter trips, the fault output

signal (ALM signal) is output (ALM signal is assigned to

terminal ABC in the initial setting).

Check that the inverter functions properly.

In addition, negative logic can be set (on when the inverter is

normal, off when the fault occurs).

2) Checking the inverter operating status by the inverter

operation ready completion signal

Operation ready signal (RY signal) is output when the

inverter power is on and the inverter becomes operative.

Check if the RY signal is output after powering on the

inverter.

3) Checking the inverter operating status by the start signal

input to the inverter and inverter running signal.

The inverter running signal (RUN signal) is output when the

inverter is running (RUN signal is assigned to terminal RUN

in the initial setting).

Check if RUN signal is output when inputting the start signal

to the inverter (forward signal is STF signal and reverse

signal is STR signal). For logic check, note that RUN signal

is output for the period from the inverter decelerates until

output to the motor is stopped, configure a sequence

considering the inverter deceleration time.

4) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal.

The output current detection signal (Y12 signal) is output when the inverter operates and currents flows in the motor.

Check if Y12 signal is output when inputting the start signal to the inverter (forward signal is STF signal and reverse

signal is STR signal). Note that the current level at which Y12 signal is output is set to 150% of the inverter rated current

in the initial setting, it is necessary to adjust the level to around 20% using no load current of the motor as reference with

Pr.150 Output current detection level.

For logic check, as same as the inverter running signal (RUN signal), the inverter outputs for the period from the inverter

decelerates until output to the motor is stopped, configure a sequence considering the inverter deceleration time.

NOTE

 Changing the terminal assignment using Pr. 190, Pr. 192 (output terminal function selection) may affect the other functions.

Make setting after confirming the function of each terminal.

(2) Backup method outside the inverter

Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure

status of the inverter itself. For example, when the inverter CPU fails, even if the interlock is provided using the inverter

fault signal, start signal and RUN signal, there is a case where a fault signal is not output and RUN signal is kept output

even if an inverter fault occurs.

Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the

backup system such as checking up as below according to the level of importance of the system.

1) Start signal and actual operation check

Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to

the inverter and detected speed of the speed detector or detected current of the current detector. Note that the motor

current runs as the motor is running for the period until the motor stops since the inverter starts decelerating even if the

start signal turns off. For the logic check, configure a sequence considering the inverter deceleration time. In addition, it is

recommended to check the three-phase current when using the current detector.

2) Command speed and actual operation check

Check if there is no gap between the actual speed and commanded speed by comparing the inverter speed command

and detected speed of the speed detector.

NOTE



The amount of current flows in the motor may become large according to the conditions such as the motor characteristics, load, acceleration/deceleration time, wiring length, etc., resulting in an overcurrent trip (OL (overcurrent alarm) then E.OC1 (overcurrent trip during acceleration), overload trip (E.THM (motor overload trip), or E.THT (inverter overload trip). (When a fault occurs, release the start command, and decrease the Pr. 0 setting 1% by 1% to reset.) (Refer to page 248.)

 The Pr. 0, Pr. 46 settings are valid only when V/F control is selected. 

General-purpose magnetic flux vector control is available.

Large starting torque and low speed torque are available with General-purpose magnetic flux vector control.

 What is General-purpose magnetic flux vector control ?

The low speed torque can be improved by providing voltage compensation to flow a motor current which meets the

load torque. With setting slip compensation (Pr. 245 to Pr. 247), output frequency compensation (slip compensation) is

made so that the actual motor speed goes closer to a speed command value. Effective when load fluctuates

drastically, etc.

General-purpose magnetic flux vector control is the same function as the FR-E500 series.

POINT

If the following conditions are not satisfied, select V/F control since malfunction such as insufficient torque and

uneven rotation may occur.

 The motor capacity should be equal to or one rank lower than the inverter capacity. (note that the capacity

should be 0.1kW or more)

 Motor to be used is any of Mitsubishi standard motor, high efficiency motor (SF-JR, SF-HR 0.2kW or more) or

Mitsubishi constant torque motor (SF-JRCA four-pole, SF-HRCA 0.4kW to 7.5kW). When using a motor other

than the above (other manufacturer's motor), perform offline auto tuning without fail.

 Single-motor operation (one motor run by one inverter) should be performed.

 The wiring length from inverter to motor should be within 30m (98.42feet). (Perform offline auto tuning in the

state where wiring work is performed when the wiring length exceeds 30m (98.42feet).)

Permissible wiring length between inverter and motor differs according to the inverter capacity and setting value

of Pr. 72 PWM frequency selection (carrier frequency). Refer to page 19 for the permissible wiring length.

(1) Control mode

 V/F control (initial setting) and General-purpose magnetic flux vector control are available with this inverter.

 V/F control is for controlling frequency and voltage so that the ratio of frequency (F) to voltage (V) is constant when

changing frequency.

 General-purpose magnetic flux vector control divides the inverter output current into an excitation current and a torque

current by vector calculation, and makes voltage compensation to flow a motor current which meets the load torque.

(General-purpose magnetic flux vector control is the same function as the FR-E500 series.)

 Uneven rotation slightly increases as compared to the V/F control. (It is not suitable for machines such as grinding

machine and wrapping machine which requires less uneven rotation at low speed.)

 When a surge voltage suppression filter (FR-ASF-H/FR-BMF-H) is connected between the inverter and motor, output

torque may decrease.

(3) Control method switching by external terminals (X18 signal)

Use the V/F switchover signal (X18) to change the control method (V/F control and General-purpose magnetic flux vector

control) with external terminal.

Turn the X18 signal on to change the currently selected control method (General-purpose magnetic flux vector control) to

V/F control.

For the terminal used for X18 signal input, set "18" in any of Pr. 178 to Pr. 182 (input terminal function selection) to assign the

function.

REMARKS

When V/F control is selected by V/F switchover (X18 signal), second function is also selected at the same time. Control between

V/F control and General-purpose magnetic flux vector control can not be switched while the inverter is running. In case control is

switched between V/F control and General-purpose magnetic flux vector control, only second function is selected.

4.3.4 Stall prevention operation (Pr. 22, Pr. 23, Pr. 48, Pr. 66, Pr. 156, Pr. 157)

This function monitors the output current and automatically changes the output frequency to prevent the inverter from

coming to trip due to overcurrent, overvoltage, etc.

It can also limit stall prevention and fast-response current limit operation during acceleration/deceleration, driving or

regeneration.

Stall prevention

If the output current exceeds the stall prevention operation level, the output frequency of the inverter is automatically changed to reduce the output current.

Fast-response current limit

If the current exceeds the limit value, the output of the inverter is shut off to prevent an overcurrent.

(3) Stall prevention operation signal output and output timing adjustment (OL signal, Pr. 157)

When the output current exceeds the stall prevention operation level and stall prevention is activated, the stall prevention

operation signal (OL signal) turns on for longer than 100ms. When the output current falls to or below the stall prevention

operation level, the output signal turns off.

Use Pr. 157 OL signal output timer to set whether the OL signal is output immediately or after a preset period of time.

This operation is also performed when the regeneration avoidance function or (overvoltage stall) is executed.

For the OL signal, set "3 (positive logic) or 103 (negative logic)" in Pr. 190 or Pr. 192 (output terminal function selection) and

assign functions to the output terminal.

performed. Normally set this parameter to 150% (initial value).

Stall prevention operation stops acceleration (makes

constant speed, and stops deceleration (makes acceleration)

during deceleration.

When stall prevention operation is performed, the OL signal is

During high-speed operation above the rated motor frequency, acceleration may not be made because the motor current

does not increase. If operation is performed in a high frequency range, the current at motor lockup becomes smaller than

the rated output current of the inverter, and the protective function (OL) is not executed even if the motor is at a stop.

To improve the operating characteristics of the motor in this case, the stall prevention level can be reduced in the high

frequency range. This function is effective for performing operation up to the high-speed range on a centrifugal separator,

etc. Normally, set 60Hz in Pr. 66 and 100% in Pr. 23.

(3) Base frequency voltage setting (Pr. 19)

Use Pr. 19 Base frequency voltage to set the base voltage (e.g. rated motor voltage).

If the setting is less than the power supply voltage, the maximum output voltage of the inverter is as set in Pr. 19.

Pr. 19 can be utilized in the following cases.

(a) When regeneration is high (e.g. continuous regeneration)

During regeneration, the output voltage becomes higher than the reference and may cause an overcurrent trip

(E.OC) due to an increased motor current.

(b) When power supply voltage variation is large

When the power supply voltage exceeds the rated voltage of the motor, speed variation or motor overheat may be

caused by excessive torque or increased motor current.
