Harmonic Suppression Guideline

The "harmonic suppression guideline for household appliances and general-purpose products" was issued by the Ministry of Economy , T rade and Industry (formerly Ministry of International T r ade 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 page 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.(Refer 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 e ffective 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 the no ises i n th e AM radi o f reque ncy b and. D edica ted filter f or the input side.

Power factor improvement reactor

Reactors must be us ed when the power factor is to be improved or whe n the inverter is installed near a large power sup ply syst em ( 1000k VA or more and wiring dista nce is within 10m). The inverter may be damaged if you do not use reactors. Make selection carefu 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 reacto r.

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 must 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 selection".

•Set "10%" in Pr. 70 "special regenerative brake duty".

Brake unit

(Refer to the instruction manual of each option for details) (Caution) Remove the ju m pers across terminals PR-PX to connect to th e i nverter.

Power regeneration common converter (FR-CV)

• (Refer to the ins truc t io n m anual 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. 1 80 t o Pr. 183 and Pr. 187(input ter m i nal function selection).

•Set "2" in Pr. 30 "regenerative function selection".

•Select the converter 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 inverter.

Earth (Ground)

To prevent an electric shock, always earth (ground) the motor and inverter. For reduction of induction noise from the pow er line of the inverter, it is recommended to wire the earth (ground) cable by return ing it to th e ear t h (g ro und) terminal of the inverter.

( For details of noise reducti on t echniques, refer to the Instruction Manual (det ai led) .

OUTLINE

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) or surge suppressor to the output side of the inverter. This will cause the inverter to trip or power factor correction capacitor and surge suppressor to be damaged. If any of the above devices are connected, imme diately remove them. If 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 on the primary side of the magnetic contactor.

• Electromagnetic wave interference The input/output (main circuit) of t he inverter includes h armonic co mponent s, which may in terfere with 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.

• The crimping terminals recommended for use to wire the po wer supply and mo tor are those pr ovided 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.

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

or more, the front cover may be lifted when there are many cables running or the

(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 fitted in o nly on e of those p ositio ns. If it is fitted in both positions at the same time, the inverte r may be damaged.

INSTALLATION AND WIRING

Offline auto tuning

The inverter measures necessary motor circuit constant and stores it to improve low speed torque.

Online auto tuning

High torque accuracy corresponding to the motor temperature variation is available.

Precautions for use of the vector inverter

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 current 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 adios ) used nea r t he inverte r. In this case, install th e op tion al FR- BIF r adio n oise f ilter (for use in the input side o nly) or FR- BSF01 or FR- BLF li ne noi se fi lter t o mi nimi ze inte rfer en 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-phas e insulation of th e 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.

Speed control operation

4CONTROL

This inverter can control a motor und er speed, torque or p osition control. (As required, set "1" (extended function parameters valid) in Pr. 160 "extended function selection".) Refer to page 28 for the setting method of Pr. 160 "extended function selection" and to page 54 for details. (Since the factory setting of Pr. 77 is "0", perform parameter write in the PU mode or during a stop.)

4.1 Speed control operation

4.1.1 Speed control

Speed control is exercised to match the speed command and actual motor speed.

Speed response........ Maximum 800rad/s by internal processing and maximum 300rad/s (without adaptive

magnetic flux observer) by analog input signal are available (motor speed response to the speed command).

4.1.2 Opera ti on tr a n sit i o n

Turning on the start signal increases the

speed up to the preset speed according to the acceleration time. Turning off the start signal decreases the

speed according to the deceleration time. When the speed has decreased down to the DC brake operation speed, operation changes to 0 speed control or servo lock. (Refer to page 66.)

Torque control 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 speed 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 ti on tr a n sit i o n

(1) When Pr. 807 = 0

The speed command value during speed restriction acts as a speed restriction level. At this time, according to the acceleration/deceleration time set in Pr. 7 "acceleration time" and Pr. 8 "deceleration time", the restriction level is increased from 0r/min upon start, and when the start signal turns off, the speed restriction level is decreased from the then speed restriction level to the DC injection brake operation speed in Pr. 10 to a stop. The speed restriction level at this time is shown below.

1)External analog speed restriction (terminal 1, 2) The analog signal (0 to +10V (±10V)) input to terminal 2 (or terminal 1) is used to give a speed restriction command.

REMARKS

• Set Pr. 73 "speed setting signal" to change between the main speed and override of term in al 2. ( Refer to the Instruction M anual (detailed).)

• If the above speed r estrictio n comma nd is g reater t han Pr. 1 "maximum s peed", t he spee d restri ction va lue is re garded as the Pr. 1 "maximum speed" value. If the speed restriction command is smaller than Pr. 2 "minimum speed", the speed restriction value is regarded as the Pr. 2 "minimum speed". Similarly when the speed restriction command is smaller than Pr. 13 "starting speed", the s peed restriction value is 0r/min.

• Set the speed restriction of terminal 1 using Pr. 868 "No. 1 terminal function selection". ( Refer to the Instruction M anual (detailed).)

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 s i gnals are assigned to terminals DI1 t o DI 4 using Pr. 180 to Pr. 183 and Pr. 187 (input terminal fu nct i on selection).

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.

Position control is exercised using the position feed amounts set in Pr. 465 to Pr. 494.

4.3.2 Position command from PLC

Position control is exercised by connecting the PLC, such as the MELSEC-Q series PLC positioning module (QD75), and the positioning control option (FR-V5AP) to the inverter.

The mode can be changed any time independently of whether the mo to r is at a st op or running or the DC brake (servo lock) is operating.

The mode can be changed when the speed is equal to or lower than the low speed detection level. When the speed is higher than the low speed detection level, changing the MC signal during rotation will not sw itch the control mode to the other, and as soon as the speed falls to or below Pr. 865 "low speed detection level", the control mode is changed according to the terminal status.

REMARKS

When "1 or 2" is set in Pr. 819 "easy gain tuning selection" and then retur 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, position control gain and speed control gain valu es ar e updated.

• Easy gain tuning is valid.

• Each control gain is automa tica l ly set from t he load inertia ratio estimated during accelerati on/

deceleration operat ion and the Pr. 818 "easy gain tuning response level setting" value.

• 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 tuning.

• 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 estimated and each cont ro l g ain is aut om atically set from the Pr. 880 "load inertia ratio" setting and Pr. 818 "easy gain tuning response level setting" value.

(2) Load inertia estimation restriction conditions

When "1" is set in Pr. 819 "easy gain tuning selection", the load inertia ratio may not be estimated well, e.g. it takes a long time for estimation, if the following conditions are not satisfied.

• 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.

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 values.

When some adjustments are required after executing easy gain tuning due to disturbance 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 control or model adaptive speed control. Refer to the Instruction Manual (detailed) for details.

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

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.

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

0: No online auto tuning 1: Start-time tuning (at start-up) 2: Adaptive magnetic flux obs er ver (normal)

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 the wi ring 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 tuning 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. O nline auto t uning of th e start-time tuning does not operate if the MRS i s inp ut, if the p r eset speed i s less than t he starting

speed (Pr. 13), or if the starting conditions of th e i nverter are not satisfied, e.g. inverter error.

2. Online auto tuning of the start-time tuning does not operate during deceleration or at a restar t dur i ng DC br ake operation.

3. Invalid for jog operation.

4. The RUN signal is not output during online auto tuning of the start-time tuning. The RUN signal turns on at a start.

5. If the period from an inverter stop to a restar t is within 4 seconds, online aut o tuning of th e start-tim e tuning is performe d

but the tuning results are not re flected.

6. Automatic restart after instanta neous po wer failure overrides when autom atic restart a fter instant aneous pow er failure is

selected.

7. Zero current detection and output curre nt det ection are valid during online auto tuning.

When power is restored after an instantaneo us power fai lure, you can start the invert er 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 will 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.

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 activ ated, the inverter output stop status i s held, and the inverter

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.

(1) Speed control

The motor hunts.

Is the speed setting varying?

PLG has not been set.

Is the speed gain too high compared to the machine?

Is there load variation?

Take proper action to stabilize

the speed setting. (Example: Enter the filter time constant (Pr. 822) to the analog terminal.)

Does the motor vibrate during acceleration/ deceleration?

Is the output torque non-linear in response to the torque command?

At the torque command of 0%, do large torque ripples occur at the instant the motor stops running?

Please contact your sales representative.

Is there no influence of noise?

Is the PWM carrier frequency low?

Set the torque setting filter (Pr. 826).

Take me asures to reduce noise.

Decrease the carrier frequency (Pr. 72).

Set the online auto tuning (Pr. 95). The torque accuracy improves. (Motor heat generation-based resistance compensation is made.)

Make torque command bias offset calibration (Pr. 904).

Since the speed restriction value increases or decreases during acceleration/deceleration, speed restriction is activated. Shorten the acceleration/deceleration time.

The excitation ratio (Pr. 854) is so low that torque is insufficient. Increase the excitation ratio (return it to the factory setting). Speed restriction is in progress. Increase the speed restriction level or decrease the torque command.

In an attempt to reduce the motor speed to 0r/min, the motor performs micro-rotation in the reverse rotation direction. At that time, speed restriction operation is performed and torque control is switched to speed control. At that time, since the factory setting of the torque restriction mode (Pr. 810) is 0 and the torque restriction command is as set in the parameter, the torque is restricted to 150%, and when an attempt is made to reduce the speed to 0r/min, torque is generated abruptly. Hence, the torque restriction level must be decreased. Set "1" in Pr.810 "torque restriction mode" to activate torque restriction.

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, benzene, t oluene and alcohol, as they will cau se 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 smoothin g capacitor 10 years Replace the board (as requ ired).

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.)

Fan cover

Fan

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

<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).
