Do not use this product until you have a full knowledge of the equipment, safety information and instructions. In this Instruction Manual (Basic), the safety instruction levels are classified into "WARNING" an d "CAUTION".

WARNIN G

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 injur y.

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

1. Electric Shock Prevention

WARNING

z While power is ON or when the inverter is running, do not

open the front cover. Otherwise you may get an electric shock.

z Do not run the invert er with the front cover o r wiring cover

removed. Otherwise you may access the exposed highvoltage terminals or the ch arging part of the circuitry and get an electric shock.

z 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.

z Before wiring or insp ection, power must be sw itched OFF.

To confirm that, LED indication of the operation panel must be checked. (It must b e OFF.) Any person who is involved in wiring or inspect ion 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 test er 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 regu lations and elect rical code (NEC secti on 250, IEC 536 class 1 and other applicable standards). A neutral-point ear thed (grounded) power su pply for 400V class inverter in compliance with EN standard must be u sed.

z Any person who is involved in wiring or inspection of this

equipment shall be f ully competent to do the wor k.

z The inverter must be installed before wiring. Otherwise you

may get an electric shock or be injured.

z Setting dial and key operations must be performed with dry

hands to prevent an electr ic shock. Otherwise you may g et an electric shock.

z Do not subject the ca bles to scratches, exc essive stress,

heavy loads or pinching. O therwise you may get an electric shock.

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

dangerous to change the cooling fan while power is ON.

z Do not touch the printed circuit boa rd or handle the cab les

with wet hands. Otherwise you may get an electric shock.

z When measuring th e main circuit capacitor ca pacity, 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 e lectric shock.

2. Fire Prevention

z 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 pow er must

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

When using a brake resistor, a sequence that will turn OFF power when a fault signal is outp ut 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 di rectly to the DC terminal s P/+

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

CAUTION

3.Injury Prevention

z T he voltage applied to each termi nal must be the ones

specified in the Instru ction Manual. Otherwise bu rst, damage, etc. may occu r.

z T he cables must be connected to t he correct terminals.

Otherwise burst, damage, etc. may occur.

z Po larity must be correct. Otherwise b urst, damage, etc.

may occur.

z W hile power is ON or for some time after power-OFF, do not

touch the inverter sin ce the inverter 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.

CAUTION

(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 In struction Manual.

z Do not install or operate the inverter if it is d amaged or has

parts missing.

z W hen 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 flam mable 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: Other wise the inverter may be damaged.

(2) Wiring

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.

CAUTION

(3) Trial run

z Be fore starting operation, each parameter must be

confirmed and adjuste d. A failure to do so may cause som e machines to make unexpected motions .

CAUTION

(4) Usage

z An y person must stay away from the equ ipment when the

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

Since pressing key may not stop output depending on

the function setting status, separate circuit and switch that make an eme rgency stop (po wer OFF, mechanical bra ke operation for emergency stop, etc.) must be provided.

z OFF status of the start signal must be confirmed before

resetting the inver ter fault. Resetting in verter alarm with the start signal ON restarts the motor suddenly.

z 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. Doi ng so may lead to fault or damage of the pr oduct.

z The electronic thermal relay function does not guarantee

protection of the motor from overheating. It is recommended to install bo th an external thermal a nd PTC thermistor for overh eat 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 an EMC filter or by other means. Otherwise nearby electronic equipment may be affected.

z Appr opriate measures must be taken to suppress

harmonics. Otherwise power supply harmonics from the inverter may heat/da mage the power factor correction capacitor and generator.

z W hen driving a 400V class motor by the inverter, the motor

must be an insulation-enha nced motor or measures mus t be taken to suppress surge voltage. Surge voltage attributable to the wirin g constants may occur at the mot or terminals, deteriorating the insulation of the motor. 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 T he inverter can be easi ly set for high-speed op eration.

Before changing its setting, the performances of the motor and machine must be f ully 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 ensu re safety.

z Be fore running an inverter which had been stored for a

long period, inspection and test operation must be performed.

z Static electricity in your body must be discharged before

you touch the product. Otherwise the product may be damaged.

z If you are installing the inverter t o drive a three-phase

device while you are contracted for lighting and power service, consult your electric power supplier.

WARNING

CAUTION

(5) Emergency stop

CAUTION

z A sa fety backup such as an emer gency 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 (sho rt 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 c arry 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.

2 INSTALLATION AND WIRING

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 40)

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 6)

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 shortened.

(Refer to page 6)

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

Use a blade terminal and a wire with a sheath stripped off for the control circuit wiring. For a single wire, strip off the sheath of the wire and apply directly. Insert the blade terminal or the single wire into a socket of the terminal.

1) Strip off the sheath about the length below. If the length of the sheath peeled is too long, a short circuit may occur among neighboring wires. If the length is too short, wires might come off. Wire the stripped wire after twisting it to prevent it from becoming loose. In addition, do not solder it.

2) Crimp the blade terminal. Insert wires to a blade terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve. Check the condition of the blade ter minal after crimping. Do not use a blade terminal of which the crimping is inappropriate, or the face is damaged.

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

Terminals SD, SE and 5 are common terminals for I/O sign als.(All common terminals are isolated from each other.) Do not earth them. Avoid connecting the terminals SD and 5 and the terminals SE and 5. Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL) and frequency output signal (FM). 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). 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) 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 (200m for terminal FM).

3) Do not short across terminals PC and SD. Inverter may be damaged.

4) When using contact inputs, use two or more parallel micro-signal contacts or twin contacts to prevent contact faults since the control circuit input signals are micro-currents.

NOTE

y Pulling out the terminal block forcefully without pushing

the open/close button all the way down may damage the terminal block.

y Use a small flathead scr ewdriver (Tip thickness: 0.4mm/

PRECAUTIONS FOR USE OF THE INVERTER

3 PRECAUTIONS FOR USE OF THE INVERTER

The FR-D700 series is a highly reliable product, but using incorrect peripheral circuits or incorrect operation/handling methods

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 appropriate size to make a voltage drop of 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 12 for the recommended wire sizes.

(5) The total wiring length should be within the prescribed length.

Especially for long distance wiring, the fast-response current limit function may decrease, or the equipment connected to the output side may malfunction. This is caused by a charging current due to the stray capacity of the wiring. Therefore, note the overall wiring length. (Refer to page 13)

(6) Electromagnetic wave interference

The input/output (main circuit) of the inverter includes high frequency components, which may interfer e with the communication devices (such as AM radios) used near the in verter. In this c ase, install the FR-BIF optional ca pacitor type filter (for use in the input side only) or FR-BSF01 or FR-BLF line noise 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 a single-phase power input model, 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 no more than 30VDC using a tester.

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

y Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits may damage

the inverter modules. These short circuits may be caused by peripheral circuit inadequacy, an earth (ground) fault caused by wiring inadequacy, or reduced motor insulation resistance.

y 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 a hostile atmosphere, securely check the motor insulation resistance etc.

(10) 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 the Instruction Manual (Applied))

(11) Across terminals P/+ and PR, connect only the brake resistor.

Do not connect a mechanical brake. The brake resistor cannot be connected to the 0.1K and 0.2K. Do not connect anything to terminals P/+ and PR. Also, never short between these terminals.

PRECAUTIONS FOR USE OF THE INVERTER

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

Application of a voltage higher than the pe rmissible vo ltage to the inverter I/O sign al 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 and 5.

(13) Provide electrical and mec hanical interlocks for MC1 a nd

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 chatt ering 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) Inverter in put side magnetic contactor (MC)

On the inverter input side, connect a MC for the following purposes. (Refer to page 6 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 autom atic 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.

If using an MC for emergency stop during operation, select an MC regarding the inverter input side current as JEM1038AC-3 class rated current.

(16) 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 th e commercial power supply, for example, switch it ON/OFF after the inverter and motor have stopped.

(17) Countermeasures against inverter-generated EMI

If electroma gnetic noise generated from the inverter causes frequency setting signal to fluc tuate and motor rotation speed to be unstable when changing motor speed with analog signal, the following countermeasures are effective.

y Do not run the signal cables and power cables (inverter I/O cables) in parallel with each other and do not bundle them. y Run signal cables as far away as possible from power cables (inverter I/O cables). y Use shield cables as signal cables. y Install a ferrite core on the signal cable (Example: ZCAT3035-1330 TDK).

Undesirable current

(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 sy stem requirements.

4 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.

(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 th e speed detector or dete cted current of the curre nt 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 spee d 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.

ENERGY SAVING OPERATION FOR FANS AND PUMPS

6 ENERGY SAVING OPERATION FOR FANS AND

PUMPS

Set the following functions to perform energy saving operation for fans and pumps.

(1) Load pattern selection (Pr. 14)

Select the optimum output characteristic (V/F characteristic) that is suitable for the

application and load characteristics.

y Set Pr.14 Load pattern selection = "1 (for variable-torque load)."

y When the output frequency is equal to or less than the base frequency, the output voltage

changes by its square in proportion to the output frequency.

Use this setting to drive a load whose load torque changes in proportion to the square of

the speed, such as a fan and a pu mp.

NOTE

y Load pattern selection is available only under V/F control. Load pattern selection is not available under General-

purpose magnetic flux vector control. ( Refer to Chapter 4 of the Instruction Manual (Applied).)

(2) Optimum excitation control (Pr. 60)

Without a detailed parameter setting, the inverter automatically performs energy saving operation.

y Set Pr.60 Energy saving control selection = "9 (Optimum excitation control mode)."

y The Optimum excitation control mode is a control system which controls excitation current to improve the motor efficiency

to the maximum and determines output voltage as an energy saving method.

REMARKS

y When the motor capacity is too small as com pared to the inverter capacity or two or more motors a re connected to one inver ter,

the energy saving effect is not expected.

NOTE

y When the Optimum excitation control mode is selected, deceleration time may be longer than the setting value. Sinc e

overvoltage alarm tends to occur as compared to the constant-torque load characteristics, set a longer deceleration

time.

y Optimum excitation control is available only under V/F control. Optimum excitation control is not available under

General-purpose mag netic flux vector cont rol. ( Refer to Chapter 4 of the Instruction Manual (Applied).)

y Optimum excitation con trol will not be perfor med during an automatic restart after instantaneous power failure .

y Since output voltage is c ontrolled by Optimum e xcitation control, output curren t may slightly increase.

z Fault or alarm indication...........When a fault or alarm occurs, the operation panel display automatically switches to the fault

z Resetting method.....................When a fault occurs, the inverter output is kept stopped. Unless reset, therefore, the inverter

z When any fault occurs, take the appropriate corrective action, then reset the inverter, and resume operation.

Not doing so may lead to the inverter fault and damage.

Inverter fa ult or alarm indications are roughly categorized as below. (1) Error message

A message regarding operational fault and setting fault by the operation panel and parameter unit (FR-PU04 /FR-PU07) is displayed. The inverter does not trip.

(2) Warning

The inverter does not trip even when a warning is displayed. However, failure to take appropriate measures will lead to a fault.

(3) Alarm

The inverter does not trip. You can also output an alarm signal by making parameter setting.

(4) Fault

When a fault occurs, the inverter trips and a fault signal is output.

REMARKS

y For the details of f ault displays and other ma lfunctions, also refer to the Instruction Manual (Applied). y Past eight faults can be displayed using the s etting dial. (Refer to page 3 for the operation.)

The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value of the electronic thermal relay function and the number of r etries are cleared (erased) by resetting the inverter. Inverter recovers about 1s after the reset is released.

Operation 1: ...... Using the operation panel, press to reset the inverter.

(This may only be performed when a fault occurs (Refer to page 35 for fault.))

Operation 2: ....... Switch power OFF once. After the indicator of the operation panel

turns OFF, switch it ON again.

Operation 3: . ..... Turn ON the reset signal (RES) for more than 0.1s. (If the RES signal

is kept ON, "Err." appears (flickers) to indicate that the inverter is in a reset status.)

∗1 The applicable motor capacity indicated is the maximum capacity applicable for use of the Mitsubishi 4-pole standard motor. ∗2 The rated output capacity assumes the following output voltages: 230V for three-phase 200V/single-phase 200V/single-phase 100V, and 440V for three-

phase 400V.

∗3 The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty, allow time for

the inverter and motor to return to or below the temperatures under 100% load. If the automatic restart after instantaneous power failure function (Pr. 57) or power failure stop function (Pr. 261) is set and power supply voltage is low while load becomes bigger, the bus voltage decreases to power failure detection level and load of 100% or more may not be available.

∗4 The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range. However,

the pulse voltage value of the inverter output side voltage remains unchanged at about that of the power supply.

∗5 The braking torque indicated is a short-duration average torque (which varies with motor loss) when the motor alone is decelerated from 60Hz in the shortest

time and is not a continuous regenerative torque. When the motor is decelerated from the frequency higher than the base frequency, the average deceleration torque will reduce. Since the inverter does not contain a brake resistor, use the optional brake resistor when regenerative energy is large. (Option brake resistor cannot be used for 0.1K and 0.2K.) A brake unit (FR-BU2) may also be used.

∗6 The power supply capacity varies with the value of the power supply side inverter impedance (including those of the input reactor and cables). ∗7 For single-phase 100V power input model, the maximum output voltage is twice the amount of the power supply voltage and cannot b e exceeded. ∗8 In a single-phase 100V power input model, the output voltage may fall down when the load is heavy, and larger output current may flow compared to a three-

phase input model. Use the motor with less load so that the output current is within the rated motor current range.

NOTE

⋅ The internal therma l integrated value of the e lectronic thermal relay f unction is reset by inver ter power reset and

reset signal input. Avoid unnecessary reset and power-OFF.

⋅ Install an external thermal relay (OCR) between the inve rter and a motor when ope rating several motors by o ne

inverter, or when using a multi-po le motor or specialized mot or. In this case, set 0A to the electro nic thermal O/L relay setting of the inver ter. For the external thermal rel ay, determine the setting value in co nsideration of the cu rrent indicated on the motor' s rating plate and the line- to-line leakage current . Self-cooling ability of a mo tor is reduced at low speed operation. U se a motor with a built-in t hermal protector.

⋅ When the difference bet ween the inverter and motor ca pacities is large and the setting is small, the p rotective

characteristics of the electron ic thermal relay function will be deteriora ted. In this case, use an external thermal relay.

⋅ A special motor cannot be protected by the electronic thermal relay function. Use the external thermal relay.
