parameters. A failure to do so may cau se some machines

to make unexpected m otions.

(4) Usage

WARNIN

z When you have chosen the retry function, stay away from

the equipment as it will restart suddenly after trip.

z Since pressing key may not stop output dependi ng

on the function setting status, provide a circuit and switch

separately to make an emerg ency stop (power OFF,

mechanical brake o peration for emergen cy stop, etc).

z Make sure that the start signal is OFF befor e resetting the

inverter alarm. A failure to do so may restart the motor

suddenly.

The load used should be a three-phase induction motor only.

inverter output may damage the equipment.

z Do not modify the equipment.

Do not perform parts removal which is not i nstructed in this

manual. Doing so may lead to fault or damage of the product.

CAUTION

The electronic thermal relay function does not guarantee

protection of the motor from overheati ng. It is recommende d

to install both an external thermal and PTC thermistor for

overheat protection.

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

frequent starting/stopping of the inverter. Otherwise, the

life of the invert er decreases.

z Use a noise filter to re duce the effect of elec tromagnetic

interference. Oth erwise nearby electron ic equipment may

be affected.

z Take measures to suppress harmonics. Otherwise power

supply harmonics from the inverter may heat/damage the

power factor correction capacitor and generator.

z When a 400V clas s motor is inverter -driven, please use an

insulation-enhanced motor or measures taken to

suppress surge voltages. Surge v oltages attributable to

the wiring constants may occur at the motor terminals,

deteriorating the insulation of the motor.

z When parameter clear or all parameter clear i s performed,

reset the required parameters before starting operations.

(5) Emergency stop

CAUTION

z Provide a safety back up such as an emergen cy brake

which will prevent the machine and equipment from

hazardous conditions if the inverter fails.

z When the breaker on the inverter inp ut side trips, check

for the wiring fault (short circuit), damage to internal parts

of the inverter, etc. Identify the cause of the trip, then

remove the cause and power ON the breake r.

z When any protectiv e function is activated, take the

appropriate correct ive action, then re set the inverter, and

resume operation.

2 INSTALLATION AND WIRING

AC power supply

AC reactor (FR -HAL)

Use within the permissible power supply specifications of the inverter. To ensure safety, use a moulded case circuit breaker, earth leakage circuit breaker or magnetic contactor to switch power ON/OFF.

(Refer to page 304)

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 3)

Magnetic contactor (MC)

Install the magnetic contactor to ensure safety. Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter life to be shorten.

(Refer to page 3)

Reactor (FR-HAL, FR-HEL option)

Reactors (option) must be used when power harmonics measures are taken, the power factor is to be improved or the inverter is installed near a large power supply system (500kVA or more). The inverter may be damaged if you do not use reactors. Select the reactor according to the model. Remove the jumpers across terminals P/+ and P1 to connect the DC reactor.

Install a noise filter to reduce the electromagnetic noise generated from the inverter. Effective in the range from about 1MHz to 10MHz. When more wires are passed through, a more effective result can be obtained. A wire should be wound four turns or more.

Great braking capability is obtained. Install this as required.

P/+

Resistor unit (FR-BR) Discharging resistor (GZG, GRZG)

The regenerative braking capability of the inverter can be exhibited fully. Install this as required.

Devices connected to the output

Do not install a power factor correction capacitor, surge suppressor or capacitor type filter on the output side of the inverter. When installing a moulded case circuit breaker on the output side of the inverter, contact each manufacturer for selection of the moulded case circuit breaker.

Earth (Ground)

To prevent an electric shock, always earth (ground) the motor and inverter. For reduction of induction noise from the power line of the inverter, it is recommended to wire the earth (ground) cable by returning it to the earth (ground) terminal of the inverter.

NOTE

 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, immediate ly remove them.

 Electrom agnetic wave interf erence

The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the communication devic es (such as AM radio s) used near the inv erter. In this case, install the FR- BIF optional capacitor type filter (for use in the input side only) or FR-BSF01 or FR-BLF common mode filter to minimize interference.

( Refer to the chapter 3 of the Instr uction Manual (applied)).

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

INSTALLATION AND WIRING

Wiring

NOTE

 Tighten the terminal screw to the specified torque. A scre w that has been tighten too loosely can cause a short circuit

or malfunction. A screw that has been tighten too tightly can cause a short circuit or malfunction due to the unit

breakage.

 Use crimping terminals with insulation sleeve to wire the power supply and motor.

The line voltage drop can be calculated by the following formula:

line voltage drop [V]=

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque

reduction) in the low speed range.

(2) Earthing (Grounding) precautions

Leakage currents flow in the inverter. To prevent an electric shock, the inverter and motor must be earthed (grounded). This

inverter must be earthed (grounded). Earthing (Grounding) must conform to the requirements of national and local safety

regulations and electrical codes. (NEC section 250, IEC 536 class 1 and other applicable standards)

Use an neutral-point earthed (grounded) power supply for 400V class inverter in compliance with EN standard.

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

Use the thickest possible earth (ground) cable. Use the cable whose size is equal to or greater than that indicated on page

13 , and minimize the cable length. The earthing (grounding) point should be as near as possible to the inverter.

POINT

To be compliant with the European Directive (Low Voltage Directive), earth (ground) the inverter according to the

instructions on page 135.

NOTE

 Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray

capacitances of the wiring, leading to a malfunction of the overcurrent protective function, fast response current limit function, or stall prevention f unction or a malfunct ion or fault of the equi pment connected on t he inverter output side . If malfunction of fast-response current limit function occurs, disable this function. If malfunction of stall prevention

function occurs, i ncrease the stall level. ( Pr. 22 Stall prevention operation level and Pr. 156 Stall prevention operation

2.4.5 Changing the control logic

The input signals are set to sink logic (SINK) when shipped from

the factory.

To change the control logic, the jumper connector above the

control terminal must be moved to the other position.

 To change to source logic, change the jumper connector in

the sink logic (SINK) position to source logic (SOURCE)

position using tweezers , a pair of long-nose pliers etc.

Change the jumper connector position before switching power

ON.

NOTE

 Fully ma ke sure that the front c over has been rein stalled securely.

 The capacity pla te is placed on the front co ver and the rating plate is on the inverter. Since these plat es have the

same serial numbers, always reinstall the remove d cover onto the original inverter.

 The sink-source logic change-over jumper 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.
