MAINTENANCE AND INSPECTION

SPECIFICATIONS

Thank you for choosing this Mitsubishi Inverter. This Instruction Manual (Applied) provides instructions for advanced use of the FR-E700 series FL remote type inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this Instruction Manual and the Instruction Manual (Basic) [IB-0600397ENG] packed with the product carefully to use the equipment to its optimum performance.

1. Electric Shock Prevention

This section is specifically about safety matters

Do not attempt to install, operate, maintain or inspect the inverter until you have read through the Instruction Manual (Basic) and appended documents carefully and can use the equipment correctly. Do not use this product until you have a full knowledge of the equipment, safety information and instructions. In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".

WARNING

CAUTION

The level may even lead to a serious consequence according to conditions. Both instruction levels must be followed because these are important to personal safety.

Incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.

While power is ON or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.

Do not run the inverter with the front cover or wiring cover removed. Otherwise you may access the exposed highvoltage terminals or the charging part of the circuitry and get an electric shock.

Even if power is OFF, do not remove the front cover except for wiring or periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock.

Before wiring or inspection, power must be switched OFF. To confirm that, LED indication of the operation panel must be checked. (It must be OFF.) Any person who is involved in wiring or inspection shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous.

This inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 536 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard must be used.

Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.

The inverter must be installed before wiring. Otherwise you may get an electric shock or be injured.

Setting dial and key operations must be performed with dry hands to prevent an electric shock. Otherwise you may get an electric shock.

Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.

Do not change the cooling fan while power is ON. It is dangerous to change the cooling fan while power is ON.

Do not touch the printed circuit board or handle the cables with wet hands. Otherwise you may get an electric shock.

When measuring the main circuit capacitor capacity, the 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.

WARNING

2. Fire Prevention

CAUTION

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

z If the inverter has become faulty, the inverter power must

be switched OFF. A continuous flow of large current could cause a fire.

z When using a brake resistor, a sequence that will turn OFF

power when a fault signal is output must be configured. Otherwise the brake resistor may overheat due to damage of the brake transistor and possibly cause a fire.

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

and N/-. Doing so could cause a fire.

A-1

3.Injury Prevention

CAUTION

z The voltage applied to each terminal must be the ones

specified in the Instruction Manual. Otherwise burst,

damage, etc. may occur.

z The cables must be connected to the correct terminals.

Otherwise burst, damage, etc. may occur.

z Polarity must be correct. Otherwise burst, damage, etc.

may occur.

z While power is ON or for some time after power-OFF, do

not touch the inverter as they will be extremely hot. Doing

so can cause burns.

4. Additional Instructions

Also the following points must be noted to prevent an

accidental failure, injury, electric shock, etc.

(1) Transportation and Mounting

CAUTION

z The product must be transported in correct method that

corresponds to the weight. Failure to do so may lead to

injuries.

z Do not stack the boxes containing inverters higher than

the number recommended.

z The product must be installed to the position where

withstands the weight of the product according to the

information in the Instruction Manual.

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

has parts missing.

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

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

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

z The inverter mounting orientation must be correct.

z Foreign conductive objects must be prevented from

entering the inverter. That includes screws and metal

fragments or other flammable substance such as oil.

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

subject it to impact.

z The inverter must be used under the following

environment. Otherwise the inverter may be damaged.

Surrounding air temperature

Ambient humidity

Storage temperature

Atmosphere

Environment

Altitude/ vibration

∗1 Temperature applicable for a short time, e.g. in transit.

-10°C to +50°C (non-freezing)

90%RH or less (non-condensing)

-20°C to +65°C *1

Indoors (free from corrosive gas, flammable gas, oil mist, dust and dirt)

Maximum 1,000m above sea level.

or less at 10 to 55Hz (directions of X, Y, Z

5.9m/s axes)

(2) Wiring

CAUTION

z 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.

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

the motor affects the rotation direction of the motor.

(3) Trial run

CAUTION

z Before starting operation, each parameter must be

confirmed and adjusted. A failure to do so may cause

some machines to make unexpected motions.

(4) Usage

WARNING

z Any person must stay away from the equipment when the

retry function is set as it will restart suddenly after trip.

z Since pressing key may not stop output depending

on the function setting status, separate circuit and switch

that make an emergency stop (power OFF, mechanical

brake operation for emergency stop, etc.) must be

provided.

z OFF status of the start signal must be confirmed before

resetting the inverter fault. Resetting inverter alarm with

the start signal ON restarts the motor suddenly.

The inverter must be used for three-phase induction motors.

Connection of any other electrical equipment to the

inverter output may damage the equipment.

z 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 for overheat protection.

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

frequent starting/stopping of the inverter. Otherwise the

life of the inverter decreases.

z The effect of electromagnetic interference must be

reduced by using a noise filter or by other means.

Otherwise nearby electronic equipment may be affected.

z Appropriate measures must be taken to suppress

harmonics. Otherwise power supply harmonics from the

inverter may heat/damage the power factor correction

capacitor and generator.

z When driving a 400V class motor by the inverter, the

motor must be an insulation-enhanced motor or measures

must be taken to suppress surge voltage. Surge voltage

attributable to the wiring constants may occur at the

motor terminals, deteriorating the insulation of the motor.

z When parameter clear or all parameter clear is performed,

the required parameters must be set again before starting

operations because all parameters return to the initial value.

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

Before changing its setting, the performances of the

motor and machine must be fully examined.

z Stop status cannot be hold by the inverter's brake

function. In addition to the inverter’s brake function, a

holding device must be installed to ensure safety.

z Before running an inverter which had been stored for a long

period, inspection and test operation must be performed.

z For prevention of damage due to static electricity, nearby

metal must be touched before touching this product to

eliminate static electricity from your body.

A-2

(5) Emergency stop

CAUTION

z A safety backup such as an emergency brake must be

provided to prevent hazardous condition to the machine

and equipment in case of inverter failure.

z When the breaker on the inverter input side trips, the

wiring must be checked for fault (short circuit), and

internal parts of the inverter for a damage, etc. The cause

of the trip must be identified and removed before turning

ON the power of the breaker.

z When any protective function is activated, appropriate

corrective action must be taken, and the inverter must be

reset before resuming operation.

(6) Maintenance, inspection and parts replacement

CAUTION

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

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

(7) Disposal

CAUTION

z The inverter must be treated as industrial waste.

1.2 Inverter and peripheral devices

AC power supply

AC reactor (FR-HAL)

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 224)

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.

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 38)

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.

EMC filter (ferrite core) *

(FR-BSF01, FR-BLF)

Install an EMC filter (ferrite core) 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.

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.

NOTE

 Up to 64 inverters can be connected when using FL remote communication.  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. (Refer to page 8)

y 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 options among the capacitor type EMC filter FR-BIF (for use in the input side only), the ferrite core type EMC filter FR-BSF01/FR-BLF, filterpack, and EMC filter to minimize the interference. (Refer to page 32).

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

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.

Installation of the inverter and enclosure design

1.4 Installation of the inverter and enclosure design

When an inverter enclosure 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 enclosure 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

Item Description

Surrounding air

temperature

Ambient humidity 90%RH or less (non-condensing)

Atmosphere Free from corrosive and explosive gases, free from dust and dirt

Maximum altitude 1,000m or less

Vibration

(1) Temperature

The permissible surrounding air temperature of the inverter is between -10 and +50°C 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.

-10 to +50

5.9m/s

°C (non-freezing)

or less at 10 to 55Hz (directions of X, Y, Z axes)

. Always operate the inverter within this

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 panel from outside.

3) Measures against condensation Condensation may occur if frequent operation stops change the in-panel 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-panel 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-panel 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. 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.

(7) Vibration, impact

The vibration resistance of the inverter is up to 5.9m/s2 at 10 to 55Hz frequency and 1mm amplitude for the directions of X, Y,

Z axes. 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 panel from resonance.

 Install the panel away from sources of vibration.

OUTLINE

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-panel 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.)

OUTLINE

Installation of the inverter and enclosure design

(3) 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 panel size.

(4) 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 tighten too loosely can cause a short circuit

or malfunction. A screw that has been tighten 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)If possible, use (l) independent earthing (grounding) in figure below for the inverter. If independent earthing

(grounding) is not available, use (ll) joint earthing (grounding) in the figure below which the inverter is connected with the other equipment at an earthing (grounding) point. The (lll) common earthing (grounding) as in the figure below, which inverter shares a common earth (ground) cable with the other equipment, must be avoided. A leakage current including many high frequency components flows in the earth (ground) cables of the inverter and inverter-driven motor. Therefore, use the independent earthing (grounding) and separated the earthing (grounding) cable of the inverter from equipments sensitive to EMI. In a high building, it may be effective to use the EMI prevention type earthing (grounding) connecting to an iron structure frame, and electric shock prevention type earthing (grounding) with the independent earthing (grounding) together.

(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 grounding point should be as near as possible to the inverter, and the ground wire 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. In this case, refer to page 39.

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 101 for Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention

operation selection )

 Refer to page 163 for details of Pr. 72 PWM frequency selection.  When using the automatic restart after instantaneous power failure function with wiring length exceeding 100m,

select without frequency search (Pr. 162 = "1 (initial value), 11"). (Refer to page 151)

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

Terminals SD and SE are common terminals for I/O signals. (Both common terminals are isolated from each other.) Do not earth them. Terminal SD is a common terminal for 24V external power supply terminal (+24). The open collector circuit is isolated from the internal control circuit by photocoupler. Terminal SE is a common terminal for the open collector output terminal (Y0). The contact input circuit is isolated from the internal control circuit by photocoupler.

(4) Wiring instructions

1) It is recommended to use the cables of 0.3mm2 to 0.75mm2 gauge for connection to the control circuit terminals.

2) The maximum wiring length should be 30m.

3) Do not short across terminals +24 and SD. It may cause a failure to the external power supply.

4) 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).

Control circuit specifications

2.3.3 Connecting the 24V external power supply

FL remote communication between the master module and the inverter can be continued while the main power circuit is OFF if the 24V external power supply is connected across terminals +24 and SD. When the main circuit power supply is turned ON, the power supply changes from the 24V external power supply to the main circuit power supply. (1) Specification of the applied 24V external power supply

 Input voltage 23.5 to 26.5VDC  Input current 0.7A or less

(2) Operation panel display during the 24V external power supply operation

 "EV" flickers.

Flickering

(3) Function of the 24V external power supply operation

 When the main power supply is turned ON during the 24V external power supply operation, a reset is performed in the

inverter, then the power supply changes to the main circuit power supply. During the reset operation in the inverter, the inverter cannot be controlled through the FL remote communication.

 The operation stops when the power supply changes to the 24V external power supply from the main circuit power

supply regardless of the operating status (in a stop, in running, in automatic restart after instantaneous power failure, in offline (online) tuning, in main circuit capacitor life measurement).

 All start signals (STF signal, STR signal, and on the operation panel) are invalid during the 24V external power

supply operation.

 Faults history and parameters can be read and parameters can be written (when the parameter write from the

operation panel is enabled) using the operation panel keys.

 The safety stop function is also valid during the 24V external power supply operation. When the safety stop function is

active, however, "SA" is not displayed because "EV" is displayed. The "EV" display has priority over the "SA" display.



The following items can be monitored during the 24V external power supply operation. Frequency setting, output current peak value actual operation time

∗ The monitored data is not updated after the power supply is changed from the main circuit power supply.

∗

, cumulative power∗, and cumulative power 2∗ (monitor dedicated to the FL remote communication)

∗

, converter output voltage peak value∗, cumulative energization time,

(Refer to page 147 for the details of each monitor.)

 The valid signals when the 24V external power supply is ON are ALM, Safety alarm, Edit, NET, READY and Y95.

(Other signals are OFF.) (Refer to page 59 and 60 for the detail of each signal.)

 The alarms, which have occurred when the main circuit power supply is ON, continue to be output after the power

supply is changed to the 24V external power supply. Perform the inverter reset to reset the alarms.

 The retry function is invalid for all alarms when the 24V external power supply is ON.  If the power supply changes from the main circuit power supply to the 24V external power supply while measuring the

main circuit capacitor's life in the PU operation mode, the measurement completes after the power supply changes back to the main circuit power supply (Pr.259 = "3").

NOTE

 When the 24V external power supply is input while the main circuit power supply is OFF, the FL remote

communication is enabled, but the inverter operation is disabled.

 Inrush current higher than the value described in (1) may flow at a power-ON. Confirm that the power supply and

other devices are not affected by the inrush current and the voltage drop caused by it.

 When the wiring length between the external power supply and the inverter is long, the voltage often drops. Select the

appropriate wiring size and length to keep the voltage in the rated input voltage range.

 In a serial connection of several inverters, the current increases when it flows through the inverter wiring near the

power supply. The increase of the current causes voltage to drop further. When connecting different inverters to different power supplies, use the inverters after confirming that the input voltage of each inverter is within the rated input voltage range.

 "E.SAF" may appear when the start-up time of the 24V power supply is too long in the 24V external power supply

operation.

brake unit should become faulty, the resistor can be unusually hot. To prevent unusual overheat and fire, install a magnetic

contactor on the inverter's input side to configure a circuit so that a current is shut off in case of fault.

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 selectionmakes 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.

 Increasing 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 or more) for the 400V class small-capacity model (7.5kW or

less), the external thermal relay is likely to operate unnecessarily because the ratio of the leakage current to the rated motor

current increases.

 Use Pr. 9 Electronic thermal O/L relay.  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. 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.

NOTE

 Install the earth leakage breaker (ELB) on the input side of the inverter.

 In the connection earthed-neutral system, the sensitivity current is blunt against an earth (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 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

rise.

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 33) 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.

instruments, receivers and sensors, are contained in the enclosure that contains the inverter or when their signal

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.

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:

zSuppression 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.

3.1.4 Harmonic suppression guideline in Japan

Harmonic currents flow from the inverter to a power receiving point via a power transformer. The harmonic suppression guideline was established to protect other consumers from these outgoing harmonic currents. The three-phase 200V input specifications 3.7kW or less are previously covered by "Harmonic suppression guideline for household appliances and general-purpose products" and other models are covered by "Harmonic suppression guideline for consumers who receive high voltage or special high voltage". However, the transistorized inverter has been excluded from the target products covered by "Harmonic suppression guideline for household appliances and general-purpose products" in January 2004 and "Harmonic suppression guideline for household appliances and general-purpose products" was repealed on September 6, 2004. All capacity and all models of general-purpose inverter used by specific consumers are covered by "Harmonic suppression guideline for consumers who receive high voltage or special high voltage" (hereinafter referred to as "Guideline for specific consumers"). "Guideline for specific consumers"

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

PRECAUTIONS FOR USE OF THE INVERTER

EMC and leakage currents

1) Calculation of equivalent capacity (P0) of harmonic generating equipment

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

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

limit in Table 3, harmonics must be calculated with the following procedure:

Σ(Ki×Pi) [kVA]

P0 = Ki: Conversion factor (refer to Table 2) Pi: Rated capacity of harmonic generating equipment∗[kVA] i: Number indicating the conversion circuit type

2) Calculation of outgoing harmonic current

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

 Operation ratio: Operation ratio = actual load factor × operation time ratio during 30 minutes  Harmonic content: Found in Table 4.

Table 5 Rated Capacities and Outgoing Harmonic Currents for Inverter Drive

∗ Rated capacity: Determined by the capacity of the applied motor and

found in Table 5. It should be noted that the rated capacity used here is

used to calculate generated harmonic amount and is different from the

power supply capacity required for actual inverter drive.

Active filter

(Active filter)

Install an AC reactor (FR-HAL) on the AC side of the inverter or a DC reactor (FR-HEL) on its DC side or both to suppress outgoing harmonic currents.

When used with a series reactor, the power factor improving capacitor has an effect of absorbing harmonic currents.

Use two transformers with a phase angle difference of 30° as in -Δ, Δ-Δ combination 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, producing a great effect of absorbing harmonic currents.

This filter detects the current of 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 a harmonic current at a detection point, providing a great effect of absorbing harmonic currents.

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). For example, MC avoids overheat or burnout of the brake resistor when heat capacity of the resistor is

insufficient or brake regenerative transistor is damaged with short while connecting an optional brake resistor.

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

3) 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

y 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 magnetic contactor must be avoided. Start and stop the inverter by turning ON/OFF the

input signal (forward/reverse rotation signal) of the FL remote communication.

y If the main power supply needs to be shut off at an inverter fault, configure a system where the output of an inverter alarm is

monitored through FL remote communication, and the magnetic contactor is turned OFF by an programmable controller output.

(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:

zMeasures

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 or less 50m to 100m exceeding 100m

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

(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 163.

 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-E700 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% or less.

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 or less.

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 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.

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

Before wiring or inspecting inside the inverter, wait 10 minutes or longer after turning OFF the power supply, then confirm

that the voltage across the main circuit terminals P/+ and N/- of the inverter is 30VDC or less using a tester, etc. The

capacitor is charged with high voltage for some time after power OFF, and it is dangerous.

(9) If "EV" is displayed on the operation panel, turn off the 24V external power supply before wiring and inspection.

(10) 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.

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

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. (Refer to page 38)

Precautions for use of the inverter

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

Do not connect a mechanical brake.

The brake resistor cannot be connected to the 0.1K or 0.2K. Leave terminals P/+ and PR open.

Also, never short between these terminals.

(13) 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.

(14) 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 when the

power supply is connected to the inverter U, V, W terminals, due

to arcs generated at the time of switch-over or chattering caused

by a sequence error.

(15) 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.

(16) Inverter input side magnetic contactor (MC)

On the inverter input side, connect a MC for the following purposes. (Refer to page 4 for selection.)

1)To release the inverter from the power supply when a fault occurs or when the drive is not functioning (e.g. emergency stop operation). For example, MC avoids overheat or burnout of the brake resistor when heat capacity of the resistor is insufficient or brake regenerative transistor is damaged with short while connecting an optional brake resistor.

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

3)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.

(17) 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 MC is provided for switching to the commercial power supply, for example, switch it ON/OFF after the inverter and motor have stopped.

(18) 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).

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

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 providing interlocks, inverter fault can be detected. For the interlocks, use different status output signals of the

inverter (virtual terminals of the FL remote communication) in combinations shown below.

No. Interlock Method Check Method Used Signals Refer to Page

1) Checking by the inverter fault output signal

When the inverter's protective function activates and the

inverter trips, the fault output signal (ALM signal) is output.

With this signal, you can check if the inverter is operating

properly.

2) Checking the inverter operation status by the reset cancel

signal

Reset cancel signal (READY signal) is output when the

reset operation of the inverter is cancelled by turning ON

the power of the inverter.

Check if the READY signal is output after the reset

operation of the inverter is canceled.

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.

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.

(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 output signal, start signal and RUN signal output, there is a case where a fault output 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.

4.5.1 Operation mode basics

 The operation mode specifies the source of the start command and the frequency command for the inverter.

 Basically, there are following operation modes.

 Network operation mode (NET operation mode): For inputting a start command and a frequency command through FL

remote communication.

 PU operation mode: For inputting start command and frequency command with the operation panel.

 At power-on, the inverter starts up in the Network operation mode. The operation mode can be switched using on the

operation panel when "1" is set in the X12 signal (Bit11). X12 signal gives a control input command through FL remote

communication. (Refer to page 57)

4.7.1 Common memory

Concept of common memory is stated below.

 The common memory is used as a shared memory between nodes which perform cyclic transmission.

 The common memory has two areas which are "common memory area 1" and "common memory area 2".

Common memory area 1 is I/O data area. Common memory area 2 is the control information area.

Two different areas can be assigned to each node.

 When the area each node sends exceed the transmission size (1024 bytes) by one frame, data is transmitted by multiple

frames.

 When receiving data which are divided into multiple frames as above, common memory is not updated until all frames sent

from one node are received. Synchronism per node unit is guaranteed.

 Entire network has an area of 8k bits (0.5k word) + 8k words = 8.5k words.

The maximum send data capacity per one node is 8.5k words. (Note that one word is 2 bytes.)

 Among common memory, both common memory area 1 and common memory 2 can be set as a transmission area of one

node as desired within the maximum area.

 Each node on FL remote network can share the same data in the whole system by broadcasting data at a constant period.

In addition, each node has own transmission area which does not overlap each other to exchange data. (For common

memory function, the transmission area assigned to one node is a receive area for other nodes.)

Message transmission

4.8 Message transmission

Message transmission is a non-periodic data communication method to communicate to a specified node when send request

is given.

Basic function of message transmission is as follows.

(1) When a node receives a token, one frame can be sent before sending cyclic frame.

(2) The message frame size which can be sent at a time is 1024 bytes at maximum.

Message frame

1024 bytes

(3) This method applies algorithm which controls refresh time not exceeding refresh cycle permissible time.

(4) Two transmission functions are available. One is "one-to-one message transmission" to send to specified nodes, and

another is "one-to-n message transmission" to send to all nodes.

(5)

y For "one-to-one message transmission", whether the other node has received data correctly or not is checked.

y For "one-to-n message transmission", response is not given after receipt of a message.

Control mode

5.3 Control mode

V/F control (initial setting), Advanced magnetic flux vector control and General-purpose magnetic flux vector control are

available with this inverter.

(1) V/F Control

It controls frequency and voltage so that the ratio of frequency (F) to voltage (V) is constant when changing frequency.

(2) Advanced (General-purpose) magnetic flux vector control

This 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. For other cases, select

Advanced magnetic flux vector control.

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 higher.)

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

Mitsubishi constant-torque motor (SF-JRCA four-pole, SF-HRCA 0.2kW to 15kW). 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.

 Wiring length from inverter to motor should be within 30m. (Perform offline auto tuning in the state where wiring

work is performed when the wiring length exceeds 30m.)

the output voltage at 0Hz in % to Pr. 0 (Pr. 46).

Adjust the parameter little by little (about 0.5%), and check the

When you want to change torque boost according to applications, switch multiple motors with one inverter, etc., use Second

torque boost.

Pr. 46 Second torque boost is valid when the RT signal is ON.

REMARKS

 The RT signal acts as the second function selection signal and makes the other second functions valid. (Refer to page 143)

NOTE

y 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 192.)

y The Pr. 0, Pr. 46 settings are valid only when V/F control is selected. y When using the inverter dedicated motor (constant-torque motor) with the

5.4.2 Advanced magnetic flux vector control (Pr. 71, Pr. 80, Pr. 81, Pr.89, Pr. 800)

Advanced magnetic flux vector control can be selected by setting the capacity, poles and type of the motor used in Pr.

80 and Pr. 81.

 Advanced 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. Output frequency compensation (slip compensation) is made so that the motor actual speed

approximates a speed command value. Effective when load fluctuates drastically, etc.

When the FR-E500 series used for General-purpose magnetic flux vector control was replaced, select General-

purpose magnetic flux vector control only when the same operation characteristic is necessary. (Refer to page 98)

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 higher.)

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

0.2kW or higher) or Mitsubishi constant-torque motor (SF-JRCA four-pole, SF-HRCA 0.2kW to 15kW). 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. (Perform offline auto tuning in the state where

wiring work is performed when the wiring length exceeds 30m.)

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.
