Harmonic Suppression Guideline

The "harmonic suppression guideline for household appliances and general-purpose products" was issued by the
Ministry of Economy , T r ade and Industry (formerly Ministry of International T rade and Industry) in September, 1994.
This guideline applies to the 3.7K or less. By installing the power factor improving reactor (FR-BEL or FR-BAL), this
product conforms to the "harmonic suppression technique for transistorized inverters (input current 20A or less)" set
forth by the Japan Electrical Manufactures' Association.

For the 3.7K or more, refer to the Instruction Manual (detailed).

Product check and name of parts

Unpack the inverter and check the capacity plate on the front cover and the rating plate on the inverter side face to
ensure that the product agrees with your order, an accessory L shaped jumper (Refer to page 15 for connection
method.)is included, and the inverter is intact.

No-fuse breaker (NFB) or earth leakage circuit braker (ELB)

The breaker mus t be selected carefully since a n in-rush current flows in the inverter at
power-on. (Refer to pag e 3.)

Magnetic contactor

Install the magnetic contactor to ensure safety. (For details, refer to the Instruction Manual
(detailed).)
Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the
inverter life to be shorten. (R ef er to page 3.)

Noise filter

Install a noise filter to reduce t he m agnetic noise generated from the inverter.
(Refer to the instruction manual of each option for details.)

• Line noise filter (FR-BSF01) (FR-BLF)
Effective in the range from about 1MHz to 10MHz. When more wires are passed
through, a more effective result can be obtained.(Note that the number of wires run
through is limited when fitting to the output side.)

• Radio noise filter (FR-BIF)
Effective in reducing t he no ises in the A M r adio f reque ncy b an d. D edica ted filter for t he
input side.

Power factor improvement reactor

Reactors must be used when the power fact or is to be improved or whe n the inverter is
installed near a large pow er sup ply sy stem ( 1000k VA or more and wiring dis tance is within
10m). The inverter m ay be damaged if you do not use reactors.
Make selection care fu lly. (Refer to page 3.)
(Refer to the instruction manual of each option for details.)

• DC reactor (FR-BEL), AC reactor (FR-BAL)

(Caution) Remove the ju m per s across terminals P-P1 to connect to the PC reactor.

Inverter

The life of the inverter is influenced by ambient temperature. The ambient
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 6.)
Wrong wiring might lead to damage of the inverter. The control signal lines m ust be
kept fully away from the main circuit to protect them from noise. (Refer to page 7.)

Brake resistor

(Refer to the instruction manual of each option for details)
(Caution) •Remove the jumpers across terminals PR-PX to connect to the inverter.

•Set "1" in Pr. 30 "regenerative function selec tion ".

•Set "10%" in Pr. 70 "special regenerative br ak e duty".

Brake unit

(Refer to the instruction manual of each option for details)
(Caution) Remove the jumpers across terminals PR-PX to c onnect to the inverter.

Power regeneration common converter (FR-CV)

• (Refer to the instruction manual of each option for details.)

(Caution) •Remove the jumpers across terminals R-R1 and S-S1.

•For a terminal to be connected to the RDYB signal of the FR-CV, set "10" (X10
signal) in any of Pr. 180 t o Pr. 183 and Pr. 187(input term inal function s el ection).

•Set "2" in Pr. 30 "regenerative function selec tion ".

•Select the conve rter one rank higher in capacity than the inverter.

Selection example: F R-V520-7.5K→FR-CV-11K, FR-V520-15K→FR-CV-18.5K
(When connecting two inverters to one FR-CV, the capacity is 11K + 18.5K =

29.5K. Therefore, select FR-CV-30K.)

Motor

Dedicated motor (Refer to page 99.)

!

This is a highly environmentally-resistant motor based on a totally-enclosed squirrel­cage induction motor designed for the vector inverter. Select the motor that matches the
inverter capacity.

PLG

For the PLG dedicated motor, refer to page 12.

Devices connected to the output

Do not install a power factor correction capacitor, surge suppressor or radio noise filter (FR­BIF option) in the output side of the i nverter.

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 return in g it to the earth (ground) terminal of the inverter.

( For details of noise reduct i on techniques, refer to the Instruction Manual (d etai le d) .

Basic configuration and connection

of peripheral devices

Caution

• Do not fit capacitive equipment such as power factor correction capacitor, radio noise filter (FR-BIF
option) o r surge suppressor to the output side of the inverter. T his will cause the inverter to trip or pow er
factor correction capacitor and surge suppressor to be damaged. If any of the above devices are con­nected, immediately rem ove them . If the FR-BIF radio noise filter is connected, switching pow er off during
motor operation may result in "E.UVT". In this case, connect the radio noise filter on the primary side of
the magnetic contactor.

• Electromagnetic wave interference
The input/output (main circuit) o f the inverter in cludes harmonic co mpo nents, wh ich may interfere wit h
the communication devices (such as AM radios) used near the inverter. In this case, install the FR-BIF
optional radio noise filter (for use in the input side only) or FR-BSF01 or FR-BLF line noise filter to mini­mize interference.

(3) Cables and wiring length

Select the recommended cable size to ensure that a voltage drop will be 2% max.
If the wiring distance between the inverter and motor is long, the motor torque will decrease due to the voltage drop of the
main circuit cable especially at high-frequency output. The PLG signal will also be affected by the voltage drop.
The following table indicates a selection example for the wiring length of 20m.

A screw that has been tighten too tightl y can cause a shor t circui t or malfun ction due to the uni t breaka ge.

• The crimping terminals recommended for use to wire t he power supply and mo tor are those p rovided
with insulation sleeves.

(4) Wiring length

The wiring length should be 100m maximum. (during vector control)

!

CAUTION

• 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 or a
malfunction or fault of the equipment connected on the secondary side. If fast-responce current
restriction malfunctions when fast-responce current restrict ion function is made valid, disable fast­responce current restriction. (Refer to Pr.156 "stall prevention operation selection". )

(3) Wiring instructions

1) Terminals 5, SD and SE are common to the I/O signals and isolated from each other. These common terminals
must not be connected to each other nor earthed (grounded).

2) 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).

3) Since the control circuit input signals are micro currents, use two parallel micro signal contacts or a twin con­tact to prevent a contact fault.

4) It is recommended to use the cables of 0.75mm
cable gauge used is 1.25mm

(4) Changing the control logic

The input signals are factory set to sink logic (SINK).
To change the control logic, the jumper connector on the back of the control circuit terminal block must be moved to
the other position.
(The output signals may be used in either the sink or source logic independently of the jumper connector position.)

1) Loosen the two mounting screws in both ends of the control circuit terminal block. (The screws cannot be
removed.) With both hands, pull down the terminal block from the back of the control circuit terminals.

2) Remove the jumper connector from the sink logic (SINK) position on the back surface of the control circuit ter­minal block and fit it to the source logic (SOURCE) position.

3) Using care not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal
block and fix it with the mounting screws.

CAUTION

1. Make sure that the control circuit connector is fitted correctly.

2. While power is on, never disconnect the control circuit terminal block.

3. The sink-source logic change-over jumper connector must be fitt ed in only on e of t hose positio ns. If
it is fitted in both positions at the same time, the inverter may be damaged.

4) Sink logic type and source logic type

• The sink logic type is a logic where a signal turns on when a current flows out of the corr esponding signal
input terminal.
Terminal SD is common to the contact input signals. T erminal SE is common to the open collector output sig­nals.

• The source logic type is a logic where a signal turns on when a current flows into the corresponding signal
input terminal.Terminal PC is common to the contact input signals. Terminal SE is common to the open col­lector output signals.

(2) For computer link communication

Using the PU connector, you can perform communication operation from a personal computer etc. By connecting
the PU connector to computers such as a personal computer and FA unit with a communication cable, you can run/
monitor the inverter and read/write parameter values using a user program.

Refer to the Instruction Manual (detailed) for details.

• Conforming Standard : EIA Standard RS-485

• Transmission form : Multidrop link system

• Communication speed : Maximum 19200bps

• Overall length : 500m

CAUTION
Do not connect the PU connector to the computer's LAN b oard, FAX modem socket or telephone con­nector. Doing so may damage the inverter due to electrical specification differences.

2.2.7 Notes on earthing (grounding)

Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed

!

(grounded).
Use the dedicated earth (ground) terminal to earth (ground) the inverter. (Do not use the screw in the case, chassis,
etc.)

Use the largest possible gauge for the earth (ground) cable. The gauge should be equal to or larger than those

!

indicated in the following table. The earthing (grounding) point should be as near as possible to the inverter to

minimize the earth (ground) cable length.

INSTALLATION AND WIRING

Precautio ns for use of th e vector in verter

2.4 Precautions for use of the vector inverter

The FR-V500 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 insulation-sleeved crimping terminals for the power supply and motor cables.
(2) Power must not be applied to th e output termina ls (U, V, W) of the inverter. Otherwise the inverter will be damaged.
(3) After wiring, wire off-cuts must not be left in the inverter.

Wire off-cuts can cause an alarm, fault or malfunction. Always keep the inverter clean.
When drilling mounting holes in a control box or the like, use care not to allow chips etc. to enter the inverter.

(4) Wire the cables of the recommended 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 high frequency.
Refer to page 11 for the recommended wire sizes.

(5) The overall wiring length should be 100m maximum.

Especially for long distance wiring, the fast-response current restriction function may be reduced or the equip­ment connected to the secondary side may malfunction or become faulty under the influe nce of a c harging c ur­rent due to the stray capacity of the wiring. Therefore, note the overall wiring length.

(6) Electromagnetic wave interference

The input/output (main circuit) of the inverter includes harmonic components, which may interfere with the communi­cation devices (such as AM r adio s) used nea r the inver te r. In this case, install the op tion al F R-BI F ra dio n oise f ilter
(for use in the input side o nly) or FR- BSF 01 or FR- BLF li ne no ise filt er to m inimi ze in terf eren ce.

(7) Do not install a power factor corr ection capacitor, surge suppressor or radio noise filter (FR-BIF option) in the

output side of the inverter.
This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices is
installed, immediately remove it. (When the FR-BIF radio noise filter is connected, switching power off during motor
operation may result in E. UVT. In this case, connect the radio noise filter in the primary side of the magnetic contactor.)

(8) When rewiring after operation, switch power off, wait for more than 10 minutes, and then make sure that the

voltage is zero using a tester, etc. For some time after power-off, there is a dangerous voltage in the capacitor.

(9) A short circuit or earth (ground) fault in 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) insulat ion and inter-p hase insulation of the inverter secon dary side before power-on.
Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance etc.

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

Always use the start signal (turn on/off terminals STF, STR-SD) to start/stop the inverter. (Refer to page 7.)

(11) Across the P and PR terminals, connect only an external regenerative brake discharge resistor.

Do not connect a mechanical brake.

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

Application (contact) of a voltage higher than the permissible voltage to the inverter I/O signal circuits or oppo­site polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiome­ter from being connected incorrectly to short terminals 10E-5.

(13) Use of single-phase power supply

Do not use single-phase power input.

(14) Precautions for use of any motor other than the dedicated motor (SF-V5R) or standard motor with PLG (SF-

JRwith PLG)
a)Vector control cannot be exercised without PLG.
b)Connect the PLG directly to the backlash-free motor shaft.

(15) Since the rated voltage differs from the commercial power supply voltage, the dedicated motor cannot perform

commercial power supply-inverter switchover operation.

By using the operation panel (FR-DU04-1), the parameter values can be copied to another inverter (only the FR­V500 series).

1) Operation procedure

After reading the parameter values from the copy source inverter, connect the operation panel to the copy des­tination inverter, and write the parameter values.
After writing the parameter values to the copy destination inverter, always reset the inverter, e.g. switch power
off once, before starting operation.

4.2 Torque control operation

4.2.1 Torque control

Torque control is exercised to develop torque as set in the torque command. The motor s peed becomes constant
when the motor output torque and load torque are balanced. For torque control, therefore, the speed is determined
by the load.
For torque control, the motor gains speed as the motor output torque becomes greater than the motor load. Here,
set the speed restriction value so that the motor speed does not increase too high. The speed restriction value is set
in the following method. When speed restriction is not set, the speed restriction value setting is regarded as 0r/min

to disable torque control.

(Toruque control is disabled under speed restriction. (Speed control is performed.))

4.2.2 Opera tion transition

Speed restriction value is
increased up to preset value
according to the Pr.7
"acceleration time" setting.

Speed restriction value

Speed restriction value is decreased
down to zero according to the Pr.8

control is stopped, and speed control (proportional control) starts.
The following shows the operations in response to the analog input command from the No. 3 terminal.

Start and stop are the same as under speed
control. A stop is made when t he STF and
STR signals are both on.

2)Speed restriction on multi-speeds
The speed restriction command can also be set for the external signals (RH, RM, RL).
(The terminals are factory-set as follows. DI1 = RH, DI2 = RM, DI3 = RL)

REMARKS

The RH, RM and R L signals are assigned to terminals D I 1 t o D I 4 using Pr. 180 to Pr. 183 and Pr. 187 (input terminal f unction

CAUTION
When speed restriction is to be made using the analog command (terminal 2), turn off the external sig­nals (RH, RM, RL). If any of external signals (RH, RM, RL) is on, multi-speed restrictions are made valid.

REMARKS

• Changing the terminal assignment in Pr. 180 to Pr. 183 and Pr. 187 may affect the other functions. Make setting after check-

ing the func t i ons of the corresponding te rm inals.

• If the value set in Pr. 187 is other than "9999", the external command cannot be used to perform reverse rotation operation.

To start reverse rotation, set "9999" (factory setting) in Pr. 187 to make the STR signal of terminal STR valid.

REMARKS

When "1 or 2" is set in Pr. 819 "easy gain tuning selection" and then ret ur ned to "0", tuning results which are automatically set
in each parameter remain unchanged.

• Easy gain tuning is invalid.

• None of the load inertia ratio, posi tion control gain and speed control gain values ar e updated.

• Easy gain tuning is valid.

• Each control gain is automa tically set from the load inertia ratio estimated dur in g acceleration/

• Pr. 880 "load inertia ratio" is used as the initial value of the load inertia ratio for tuning. Estimated
value is set in Pr. 880 during tunin g.

• Used when the load inertia ratio cannot be estimated well due to load disturbance and such or when

the load inertia ratio is known in advance, for example. At this time, the load inertia ratio is not

• Time taken for acceleration/deceleration to reach 1500r/min is 5s or less.

• Speed is 150r/min or more.

• Acceleration/deceleration torque is 10% or more of the rated torque.

• Abrupt disturbance is not applied during acceleration/deceleration.

REMARKS

Operation when the first or second function is selected
Load inertia estimation and gain calculation are performed only when the RT ter minal is off. The gain calculated is also
reflected only on these parameters. When the RT terminal is on, both the inertia estimation value and gain remain unchanged
from the previous val ues.

When some adjustments are required after executing easy gain tuning due to dis turbance and such,

perform fine adjustment (adjustment of Pr. 820, Pr. 821) by manual input. (Set "0" (without gain tuning) in
Pr. 819 "easy gain tuning".)
If the fast responsiveness to the speed command is desired, consider exercising speed feed forward

Online auto tuning

4.6 Online auto tuning

Excellent torque accuracy is provided even if the secondary resistance value of the motor varies with the

!

rise of the motor temperature.

4.6.1 Parameters

• For the motor with PLG, set "2" in Pr. 95 "online auto tuning selection".

Parameter Name Factory Setting Setting Range Remarks

0: No online auto tuning

95 Online auto tuning selection 0 0, 1, 2

4.6.2 Pr. 95="1" (start-time tuning)

The current at a start is detected to compensate for the secondary resistance of the motor so that excellent
characteristics are provided regardless of the change in value of the secondary resistance of the motor with the rise
of the motor temperature.

CAUTION

1. Perform offline auto tuning in the mode with rotation before performing start-time tuning of the online
auto tuning.

1: Start-time tuning (at start-up)
2: Adaptive magnetic flux observer (normal)

4.6.3 Pr. 95 = "2" (normal tuning)/adaptive magnetic flux observer

This function is effective for torque accuracy improvement when using the motor with PLG.
The current flowing in the motor and the inverter output voltage are used to estimate/observe the magnetic flux in
the motor.
The magnetic flux of the motor is always detected with high accuracy so that excellent characteristics are provided
regardless of the change in the temperature of the secondary resistance.
Set "2" when exercising PLG vector control.

CAUTION

1. For the SF-V5R, SF-JR (with PLG) or SF-HRCA (with PLG), it is not necessary to perform offline auto
tuning to select adaptive magnetic flux observer. (Note that it is necessary to perform offline auto
tuning (hon-rotation mode) for th e wiring length resistance to be reflected on the control when the
wiring length is long (30m or longer as reference).)

2. For using start-time tuning in vertical lift applications, examine the utilization of a brake sequence for
the brake opening timing at a start. Though the tu ning ends in about a maximum of 500ms after a
start, torque is not provided fully during that period. Therefore, note that there may be a possibility of
gravity drop.

REMARKS

1. Online auto tuning of the start-time tuning does not operate if the MRS is input, if the preset speed is less than the starting

speed (Pr. 13), or if the starting conditions of th e i nve rt er ar e not satisfied, e.g. inverter error.

2. Online auto tun in g of th e st ar t -ti m e tu ni ng does not operate during deceleration or at a rest ar t dur i ng D C br ake operation.

CAUTION
Torque command bias and gain can not be set by applying an external negative setting signal to the
torque command No. 3 or No. 1 terminal.

<Setting>

There are the following three methods to adjust the speed setting voltage bias and gain.

1) Method to adjust any point by application of a voltage to across terminals 2(1)(3) - 5

2) Method to adjust any point without application of a voltage to across terminals 2(1)(3) - 5

3) Method that does not adjust the bias voltage

(Example) Pr. 903 "speed setting No. 2 gain"

(Pr. 902 to Pr. 920 can be adjusted in the similar manner.)

<Adjustment procedure> Using the speed setting signal from the operation panel (FR-DU04-1) to make speed setting

auxiliary input) is added to the speed setting signal.

2. For the operation procedure using the parameter un it (FR-PU04V), refer t o the FR-PU04V in struction
manual.

3. When applying voltage for calibration, the difference of the set in put voltag e of bias and gain shou ld
be 5% or more. If the difference is 5% or less, a setting error will occur.

CAUTION

Take care when setting any value other than "0" as the bias speed at 0V. Even if a speed command is
not given, merely turning on the start signal will start the motor at the preset speed.

When power is restored after an instantaneo us pow er failure, you can start the inverter
without stopping the motor (in a coasting status). When this time (Pr. 57) elapses after
power was restored, the inverter begins to restart.
When you set "9999", the inverter wil l not restart. Generally, you may set "0", but you
can adjust the time (0, 0.1 to 5s, 9999) according to the load magnitude.
When the restart coasting time (Pr. 57) elapses, the output voltage is risen gradually.
Set this cushion time (Pr. 58) (0 to 60s).
Normally, you can perform operation with the factory settings, but you can adjust them
according to the load magnitude. Pr. 58 is valid only during V/F control.

You can make remote setting of the speed when the operation panel is located away
from the control box.
0: None

0 to 3600r/min, 9999

You can select to exercise Soft-PWM control and long wiring mode. When Soft-PWM
control is made valid, you can change the metallic tone of motor sound into an
unoffending complex tone. Surge voltage is surpressed in the long wiring mode
regardless of the wiring length between the inverter and motor. (When operating a
400V motor with wiring length of 40m or more, select long wiring mode.)
0: Soft-PWM control invalid, long wiring mode invalid
1: Soft-PWM control valid (when Pr. 72 = "1 or 2"), long wiring mode invalid
10: Soft-PWM control invalid, long wiring mode valid (carrier frequency is 2.25Hz *)
11: Soft-PWM control valid, long wiring mode valid (carrier frequency is 2.25Hz *)

You can control the operation of the cooling fan built in the inverter.
0: The fan is always operated at power-on of the inverter.
1: The fan is always on while the inverter is running . During a stop , the inverter statu s is

monitored and the fan switches on-off according to the temperature.

Set to allow the motor to be coasted to a stop by turning off the start command during
V/F or speed control.
0 to 100s: Coasting to stop
9999: Deceleration to stop

Errors (Alarms)

6 ERRORS AND PROTECTIVE FUNCTIONS

6.1 Errors (Alarms)

If any fault has occurred in the inverter, the corresponding protective function is activated to bring the inverter to an
alarm stop and automatically give the corresponding error (alarm) indication on the PU display.
If the fault does not correspond to any of the following errors or if you have any other problem, please contact your
sales representative or distributor.

When the alarm output signal holding protective function is activated, opening the magnetic contactor (MC)

!

provided on the inverter's power supply side will cause the control power of the inverter to be lost and the alarm
output not to be held.
When the alarm display protective function is activated, the operation panel display section is changed

!

automatically.
When the resetting method protective function is ac tivated, the inverter output stop status is held, and the inve rter

!

cannot restart unless it is reset. T o reset, switch power off once, then on again, or turn on the RES signal for more
than 0.1 seconds.
If the RES signal is kept on, "Err." appears (flickers) to indicate that the inverter is in a reset status.
When any protective function is activated, take the corresponding corrective action, then reset the inverter, and

!

resume operation.

6.1.1 Major faults

When the protective function is activated, the inverter output is shut off and an alarm is output.

Instant aneous power failure protection (*4)
If a power failure occurs for longer than 15ms (this also applies to inverter inp ut shut-off), the

instantaneous power failure protective function is activated to stop the inverter output in order to
prevent the control circuit from malfunctioning. At this time, the alarm warning output contacts open

Precautions for maintenance and

inspection

6.5 Precautions for maintenance and inspection

6.5.1 Precautions for maintenance and inspection

The inverter is a static unit mainly consisting of semiconductor devices. Daily inspection must be performed to
prevent any fault from occurring due to the adverse effects of the operating environment, such as temperature,
humidity, dust, dirt and vibration, changes in the parts with time, service life, and other factors.

Precautions for maintenance and inspection

!

For some short time after the power is switched off, a high voltage remains in the smoothing capacitor. When
accessing the inverter for inspection, switch power off, wait for more than 10 minutes, and then make sure that the
voltage across the main circuit terminals P-N of the inverter is not more than 30VDC using a tester, etc.

6.5.2 Check items

(1) Daily inspection

Basically, check for the following faults during operation.

1) Motor operation fault

2) Improper installation environment

3) Cooling system fault

4) Unusual vibration and noise

5) Unusual overheat and discoloration
During operation, check the inverter input voltages using a tester.

(2) Cleaning

Always run the inverter in a clean status.
When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral detergent or ethanol.

CAUTION

Do not use solvent, such as acetone, benz ene, toluene and alcohol, as th ey will cause the inverter sur­face paint to peel off.

6.5.3 Periodic inspection

Check the areas inaccessible during operation and requiring periodic inspection. For periodic inspection, consult us.

1) Cooling system fault : Clean the air filter, etc.

2) Tightening check and retightening : The screws and bolts may become loose due to vibration, temperature
changes, etc. Check and tighten them.
Tighten them according to the specified tightening torque. (Refer to
page 11.)

3) Check the conductors and insulating materials for corrosion and damage.

4) Measure insulation resistance.

5) Check and change the cooling fan and relay.

6.5.4 Insulation resistance test using megger

1) Before performing the insulation resistance test on the external circuit, disconnect the cables from all terminals

of the inverter so that the test voltage is not applied to the inverter.

2) For the continuity test of the control circuit, use a tester (high resistance range) and do not use the megger or buzzer.

3) For the inverter, conduct the insulation resistance test on the main circuit only as shown below and do not per-

form the test on the control circuit. (Use a 500VDC megger.)

6.5.7 Replacement of parts

The inverter consists of many electronic parts such as semiconductor devices.
The following parts may deteriorate with age because of their structures or physical characteristics, leading to
reduced performance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically.

Part Name Standard Replacement Interval Description

Cooling fan 2 to 3 years Replace (as required)

Main circuit smoothing capacitor 10 years Replace (as required)

On-board smooth in g capacitor 10 years Replace the board (as required).

Relays — Replace as required.

CAUTION

For parts replacement, consult the nearest Mitsubishi FA Center.

Precautions for maintenance and

inspection

(1) Cooling fan

The cooling fan is used to cool heat-generating parts such as the main circuit semiconductors. The life of the
cooling fan bearing is usually 10,000 to 35,000 hours. Hence, the cooling fan must be replaced every 2 to 3 years if
the inverter is run continuously. When unusual noise and/or vibration is noticed during inspection, the cooling fan
must be replaced immediately.

Removal

!

1) Remove the front cover and wiring cover. (Refer to page 4.)

2) Push the catches from above and remove the fan cover.

3) Disconnect the fan connectors.

4) Remove the fan.

Fan connectors

! Reinstallation

1) After confirming the orientation of the fan, reinstall the fan so that the
arrow on the left of "AIR FLOW" faces up.

AIR FLOW

<Fan side face>

<Example: FR-V520-5.5K>

CAUTION

Installing the fan in the opposite air flow direc­tion can cause the inverter life to be shorter.

2) Reconnect the fan connectors.
When wiring, use care to avoid the cables being caught by the fan.

3) Reinstall the fan cover.

(2) Smoothing capacitors

A large-capacity aluminum electrolytic capacitor is used for smoothing in the main circuit DC section, and an
aluminum electrolytic capacitor is used for stabilizing the control power in the control circuit. Their characteristics
are deteriorated by the adverse effects of ripple currents, etc. The replacement intervals greatly vary with the
ambient temperature and operating conditions. When the inverter is operated in air-conditioned, normal
environment conditions, replace the capacitors about every 10 years.
The appearance criteria for inspection are as follows:

1) Case: Check the side and bottom faces for expansion

2) Sealing plate: Check for remarkable warp and extreme crack.

3) Check for external crack, discoloration, fluid leakage, etc. Judge that the capacitor has reached its life when
the measured capacitance of the capacitor reduced below 80% of the rating.

(3) Relays

To prevent a contact fault, etc., relays must be replaced according to the cumulative number of switching times
(switching life).
