INSTALLATION AND WIRING

2.1.1 Instructions for installation

1) Handle the unit carefully. The inverter uses plastic parts. Handle it gently to protect it from damage. Also, hold the unit with even strength and do not apply too much strength to the front cover alone.

2) Install the inverter where it is not subjected to vibration. Note the vibration of a cart, press, etc.

3) Note on ambient temperature The inverter life is under great influence of ambient temperature. In the place of installation, ambient temperature must be within the permissible range (-10°C to +40°C (14°F to 104°F) ). Check that the ambient temperature is within that range in the positions shown in figure 3). *For FR-A560L-375, 450K at constant torque (CT) rating maximum ambient temperature can be 50°C (122°F).

4) Install the inverter on a non-combustible surface. The inverter will be very hot (maximum. about 150°C (302°F) ). Install it on a non-combustible surface (e.g. metal). Also leave sufficient clearances around the inverter.

5) Avoid high temperature and high humidity. Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity.

Note: The cooling section outside the enclosure has the cooling fan. Do not use the inverter in any environment

where it is exposed to waterdrops, oil mist, dust, etc.

6) Avoid places where the inverter is exposed to oil mist, flammable gases, fluff, dust, dirt, etc. Install the inverter in a clean place or inside a "totally enclosed" panel which does not accept any suspended matter.

7) Note the cooling method when the inverter is installed in an enclosure. When an inverter is mounted in an enclosure, the ventilation fans of the inverter and enclosure must be carefully positioned to keep the ambient temperature of the inverter below the permissible value. If they are installed in improper positions, the rise in ambient temperature will result in reduced performance of the inverter.

8) Secure the inverter vertically, with bolts. Install the inverter on an installation surface securely and vertically with screws or bolts.

3) Note on ambient temperatures

INSTALLATION AND WIRING

2.2.2 Wiring of the main circuit

(1)

Wiring instructions

1) Power must not be applied to the output terminals (U, V, W) of the inverter. Otherwise the inverter will be damaged.

2) After wiring, wire off-cuts must not be left in the inverter. Wire off-cuts can cause an alarm, failure or malfunction. Always keep the inverter clean.

3) Use thick cables 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.

4) Electromagnetic wave interference The input/output (main circuit) of the inverter includes harmonic components, which may interfere with the communication devices (such as AM radios) used near the inverter. In this case, use shielded wire cables as the power cable.

5) Do not install a power 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 are installed, immediately remove them.

6) When rewiring after operation, make sure that the POWER lamp has gone off, and when more than 10minutes have elapsed after power-off, check with a tester that the DC bus voltage is zero. After that, start rewiring work. For some time after power-off, there is a dangerous voltage in the capacitor.

7) Top attachments should be removed before operating because of Air exhaust. Side attachments can be used for fixing the unit. (See page 44)

Notes on Grounding

• Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be grounded (grounding resistance: 10Ω or less.)

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

• The ground cable should have a thickness of 38mm2, or more, and be as short as possible. The grounding

point should be as close to the inverter as possible.

INSTALLATION AND WIRING

2.2.3 Wiring of the control circuit

(1)

Wiring instructions

1) Terminals SD, SE and 5 are common to the I/O signals and isolated from each other. These common terminals must not be connected to each other or earthed.

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) The frequency input signals to the control circuit are micro currents. When contacts are required, use two or more parallel micro signal contacts or a twin contact to prevent a contact fault.

4) It is recommended to use the cables of 0.75mm2 gauge for connection to the control circuit terminals. If the cable gauge used is 1.25mm2 or more, the front cover may be lifted when there are many cables running or the cables are run improperly, resulting in an operation panel or parameter unit contact fault.

(2)

Terminal block layout

NA version（OR Version

In the control circuit of the inverter, the terminals are arranged as shown below:

Terminal screw size: M3.5

）

B C PC AM 10 E 1 0 2 5 4 1

RM RH RT AU STOP MRS RES SD FM

SE RUN SU IPF OL FU SD STF STR JOG CS

EC version

Terminal screw size : M3

A B C SD AM 10E 10 2 5 4 1 RL RM RH RT AU

SE RUN SU LPF OL FU STOP MRS RES PC STF STR JOG CS FM SD

1) For the wiring of the control circuit, strip the sheaths of the cables and use them as they are. Strip the sheath to the following dimension. If too much is stripped this may cause a short circuit with the neighboring cable. If too little stripped this may cause cable disconnection.

6mm ± 1mm

2) Loosen the terminal screw and insert the cable into the terminal.

3) Tighten the screw to the specified torque.

Undertigthening can cause cable disconnection or malfunction. Overtightening can cause a short circuit or malfunction due to the screw or unit damaged.

Tightening torque : 5 to 6 kgf･cm

Note : Wire the stripped cable by twisting it to prevent it from becoming loose. (Do not plate the cable with

solder.)

Note : 1. Use a NFB (No fuse breakers) or fuse on the inverter input (primary) side.

2. Make sure that the control circuit terminal wiring does not touch power circuit terminals (or screws) or conducting power circuit.

INSTALLATION AND WIRING

(3)

Changing the control logic

The input signals are set to sink logic for the NA version, and to source logic for the EC version. To change the control logic, the 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 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 connector in the sink logic position on the back surface of the control circuit terminal block and fit it to the source logic position.

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

Note: 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 connector must be fitted in only one of those positions. If it is fitted in both positions at the same time, the inverter may be damaged.

INSTALLATION AND WIRING

4) Sink logic type

• In this logic, a signal switches on when a current flows out of the corresponding signal input terminal. Terminal SD is common to the contact input signals. Terminal SE is common to the open collector output signals.

How to use terminals “STOP”, “CS” and “PC”

1) Using the “STOP” terminal A connection example (for sink logic) for self-holding the start signal (forward rotation, reverse rotation) is shown on the right.

2) Using the “CS” terminal This terminal is used to perform automatic restart after instantaneous power failure and commercial power supply-inverter switch-over operation.

<Example: Automatic restart after instantaneous power failure in sink logic>

Connect terminals CS-SD and set a value other than “9999” in Pr. 57 “coasting time for automatic restart after instantaneous power failure”.

3) Using the “PC” terminal This terminal can be used as 24VDC power output using SD as a common terminal. Specifications: 18V to 26VDC, 0.1A permissible current Note that the wiring length should be within 30m. Do not short terminals PC-SD. When terminal PC is used as a 24V power supply, leakage current from transistor output cannot be prevented.

INSTALLATION AND WIRING

2.2.5 Design information

1) For commercial power supply-inverter switch-over operation, provide electrical and mechanical interlocks for MC1 and MC2 designed for commercial power supply-inverter switch-over. When there is a commercial power supply-inverter switch-over circuit as shown below, the inverter will be damaged by leakage current from the power supply due to arcs generated at the time of switch-over or chattering caused by a sequence error.

2) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the inverter’s primary circuit 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.

3) When the power supply used with the control circuit is different from the one used with the main circuit, make up a circuit which will switch off the main circuit power supply terminals R, S, T<L power supply terminals , R1, S1<L

, L21> for the control circuit are switched off.

4) Since the input signals to the control circuit are on a low level, use two parallel micro signal contacts or a twin contact for contact inputs to prevent a contact fault.

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

6) Do not apply a voltage directly to the alarm output signal terminals (A, B, C). Always apply a voltage to these terminals via a relay coil, lamp, etc.

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

This may also be activated by a surge voltage generated in the power

supply system.

E.THM

Motor

The electronic overcurrent protection in the inverter detects motor

overheat due to overload or cooling capability reduced during constant-

speed operation. When 85% of the preset value is reached, pre-alarm

(TH indication) occurs. When the specified value is reached, the

protective circuit is activated to stop the inverter output. When a special

motor such as a multi-pole motor or more than one motor is run, the

motor cannot be protected by the electronic overcurrent protection.

If a current not less than 150% of the rated output current flows and

overcurrent shut-off (OC) does not occur (200% or less), inverse-time

characteristics cause the electronic overcurrent protection to be

activated to stop the inverter output. (Overload immunity: 150%, 60 sec)

At low-speed regions, the operation time may be short.

Instantaneous power failure

protection

If a power failure has occurred in excess of 15msec (this applies also

to inverter input shut-off), this function is activated to stop the inverter

output to prevent the control circuit from misoperation. At this time, the

alarm output contacts are opened (across B-C) and closed (across A-

C).

(Note 1) If a power failure persists for more than 100ms, the alarm

output is not provided, and if the start signal is on at the time of power

restoration, the inverter will restart. (If a power failure is instantaneous

within 15msec, the control circuit operates properly.)

E.UVT

Voltage

Undervoltage protection

If the inverter power supply voltage drops, the control circuit will not

operate properly. Furthermore, the motor torque could drop and the heat

generated may increase. The inverter output will be stopped if the

power supply voltage drops to 150V (approx. 300V for 400V class) or

less.

The undervoltage protection function will activate if the DC reactor

accessory is not used.

E.FIN

Fin overheat

If the cooling fin overheats, the temperature sensor is activated to stop

the inverter output.

If any fault has occurred in the inverter, the corresponding protective function is activated and the error (alarm) indication appears automatically on the PU display. When the protective function is activated, refer to "5.2 Troubleshooting" and clear up the cause by taking proper action. If an alarm stop has occurred, the inverter must be reset to restart it.

To know the operating status at the occurrence of alarm

When any alarm has occurred, the display automatically switches to the indication of the corresponding protective function (error). By pressing the [MODE] key at this point without resetting the inverter, the display shows the output frequency. In this way, it is possible to know the running frequency at the occurrence of the alarm. It is also possible to know the current in the same manner. However, these values are not stored in memory and are erased when the inverter is reset.

5.2.2 Faults and check points

POINT: Check the corresponding areas. If the cause is still unknown, it is recommended to initialize the

parameters (return to factory settings), re-set the required parameter values, and check again.

(1)

Motor remains stopped.

1) Check the main circuit Check that a proper power supply voltage is applied (operation panel display is provided).

Check that the motor is connected properly.

2) Check the input signals

Check that the start signal is input.

Check that both the forward and reverse rotation start signals are not input.

Check that the frequency setting signal is not zero.

Check that the AU signal is on when the frequency setting signal is 4 to 20mA.

Check that the output stop signal (MRS) or reset signal (RES) is not on.

Check that the CS signal is not off when automatic restart after instantaneous power failure is selected

(Pr. 57 = other than "9999").

3) Check the parameter settings

Make sure that the operation panel is connected securely with the inverter.

(10) POWER lamp is not lit.

Make sure that the wiring and installation are correct.

5.3 Precautions for Maintenance and Inspection

PROTECTIVE FUNCTIONS

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

5.3.1 Precautions for maintenance and inspect ion

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. When more than 10 minutes have elapsed, make sure that the voltage across the main circuit terminals P-N of the inverter is 30VDC or less using a tester, etc.

5.3.2 Check items

(1)

Daily inspections

• Check the following:

1) Motor operation fault

2) Improper installation environment

3) Cooling system fault

4) Unusual vibration and noise

5) Unusual overheating and discoloration

• During operation, check the inverter input voltages using a tester.

(2)

Cleaning

Always run the inverter in a clean state. When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral detergent or ethanol. Note: Do not use solvent, such as acetone, benzene, toluene and alcohol, as they will cause the inverter surface

paint to peel off. Do not use detergent or alcohol to clean the display and other sections of the operation panel (FR-DU04) or parameter unit (FR-PU04) as these sections will deform.

5.3.3 Periodic inspection

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

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

2) Screws and bolts: ･････････ These parts may become loose due to vibration, temperature changes, etc. Check that they are tightened securely and retighten as necessary.

3) Conductors and insulating materials: Check for corrosion and damage.

4) Insulation resistance: Measure.

5) Cooling fan, smoothing capacitor, relay: Check and change if necessary.

PROTECTIVE FUNCTIONS

5.3.4 Insulation resistance test using megger

1) Before performing the insulation resistance test using a megger 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 perform the test on the control circuit. (Use a 500VDC megger.)

5.3.6 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 failure of the inverter. For preventive maintenance, the parts must be changed periodically.

(1)

Cooling fan

The cooling fan cools heat-generating parts such as the main circuit semiconductor devices. The life of the cooling fan bearing is usually 10,000 to 35,000 hours. Hence, the cooling fan must be changed 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 changed immediately.

(2)

Smoothing capacitors

A large-capacity aluminum electrolytic capacitor is used for smoothing the DC in the main circuit, and an aluminum electrolytic capacitor is also used for stabilizing the control power in the control circuit. Their characteristics are adversely affected by ripple current, etc. When the inverter is operated in an ordinary, airconditioned environment, change the capacitors about every 5 years. When 5 years have elapsed, the capacitors will deteriorate more rapidly. Check the capacitors at least every year (less than six months if their life will be expired soon). Check the following:

1) Case (side faces and bottom face for expansion)

2) Sealing plate (for remarkable warping and extreme cracks)

3) Explosion-proof valve (for excessive valve expansion and operation)

4) Appearance, external cracks, discoloration, leakage. When the measured capacitance of the capacitor has reduced below 85% of the rating, change the capacitor.

(3)

Relays

To prevent a contact fault, etc., relays must be changed according to the number of accumulative switching times (switching life). See the following table for the inverter parts replacement guide. Lamps and other short-life parts must also be changed during periodic inspection.

Replacement Parts of the Inverter
