i

Application

• FRENIC-Eco is designed to drive a three-phase induction motor. Do not use it for single-phase motors
or for other purposes.

Fire or an accident could occur.

• FRENIC-Eco may not be used for a life-support system or other purposes directly related to the human
safety.

• Though FRENIC-Eco is manufactured under strict quality control, install safety devices for applications
where serious accidents or material losses are foreseen in relation to the failure of it.

An accident could occur.

Installation

• Install the inverter on a nonflammable material such as metal.

Otherwise fire could occur.

• Do not place flammable matter nearby.

Doing so could cause fire.

• Do not support the inverter by its terminal block cover during transportation.

Doing so could cause a drop of the inverter and injuries.

• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter or from accumulating on the heat sink.

Otherwise, a fire or an accident might result.

• Do not install or operate an inverter that is damaged or lacking parts.

Doing so could cause fire, an accident or injuries.

• Do not get on a shipping box.

• Do not stack shipping boxes higher than the indicated information printed on those boxes.

Doing so could cause injuries.

ii

Wiring

• When wiring the inverter to the power source, insert a recommended molded case circuit breaker
(MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)
(with overcurrent protection) in the path of power lines. Use the devices within the recommended
current range.

• Use wires in the specified size.

Otherwise, fire could occur.

• Do not use one multicore cable in order to connect several inverters with motors.

• Do not connect a surge killer to the inverter's output (secondary) circuit.

Doing so could cause fire.

• Ground the inverter in compliance with the national or local electric code.

Otherwise, electric shock could occur.

• Qualified electricians should carry out wiring.

• Be sure to perform wiring after turning the power OFF.

Otherwise, electric shock could occur.

• Be sure to perform wiring after installing the inverter body.

Otherwise, electric shock or injuries could occur.

• Ensure that the number of input phases and the rated voltage of the product match the number of
phases and the voltage of the AC power supply to which the product is to be connected.

Otherwise fire or an accident could occur.

• Do not connect the power source wires to output terminals (U, V, and W).

Doing so could cause fire or an accident.

• Generally, control signal wires are not enforced- insulated. If they accidentally touch any of live parts in
the main circuit, their insulation coat may break for any reasons. In such a case, an extremely high
voltage may be applied to the signal lines. Make a complete remedy to protect the signal line from
contacting any hot high voltage lines.

Otherwise, an accident or electric shock could occur.

• Wire the three-phase motor to terminals U, V, and W of the inverter, aligning phases each other.

Otherwise injuries could occur.

• The inverter, motor and wiring generate electric noise. Take care of malfunction of the nearby sensors
and devices. To prevent the motor from malfunctioning, implement noise control measures.

Otherwise an accident could occur.

iii

Operation

• Be sure to install the terminal block cover and the front cover before turning the power ON. Do not
remove the covers while power is applied.

Otherwise electric shock could occur.

• Do not operate switches with wet hands.

Doing so could cause electric shock.

• If the retry function has been selected, the inverter may automatically restart and drive the motor
depending on the cause of tripping.

(Design the machinery or equipment so that human safety is ensured after restarting.)

• If the stall prevention function (current limiter), automatic deceleration, and overload prevention control
have been selected, the inverter may operate at an acceleration/deceleration time or frequency
different from the commanded ones. Design the machine so that safety is ensured even in such cases.

Otherwise an accident could occur.

• The
F02 (= 0, 2 or 3). When the keypad operation is disabled, prepare an emergency stop switch separately
for safe operations.

Switching the run command source from keypad (local) to external equipment (remote) by turning ON

the "Enable communications link" command (LE) or "Switch run command 2/1" command (FR2/FR1),
disables the
function code H96 (= 1 or 3).

• If an alarm reset is made with the Run command signal turned ON, a sudden start will occur. Ensure that
the Run command signal is turned OFF in advance.

Otherwise an accident could occur.

• If you enable the "Restart mode after momentary power failure" (Function code F14 = 3, 4, or 5), then
the inverter automatically restarts running the motor when the power is recovered.

(Design the machinery or equipment so that human safety is ensured after restarting.)

• If you set the function codes wrongly or without completely understanding this instruction manual and
the FRENIC-Eco User's Manual (MEH456), the motor may rotate with a torque or at a speed not
permitted for the machine.

An accident or injuries could occur.

• Do not touch the inverter terminals while the power is applied to the inverter even if the inverter stops.

Doing so could cause electric shock.

iv

• Do not turn the main circuit power (circuit breaker) ON or OFF in order to start or stop inverter operation.
Doing so could cause failure.

• Do not touch the heat sink because they become very hot.
Doing so could cause burns.

• Setting the inverter to high speeds is easy. Before changing the frequency (speed) setting, check the
specifications of the motor and machinery.

• The brake function of the inverter does not provide mechanical holding means.

Injuries could occur.

Setting control switches

• Before setting up any internal control switches, turn OFF the power and wait more than five minutes for
models of 30 kW or below, or ten minutes for models of 37 kW or above. Make sure that the LED
monitor and charging lamp (on models of 37 kW or above) are turned OFF. Further, make sure, using a
multimeter or a similar instrument, that the DC link bus voltage between the terminals P (+) and N (-) has
dropped below the safe voltage (+25 VDC).

Otherwise electric shock could occur.

Maintenance and inspection, and parts replacement

• Turn the power OFF and wait for at least five minutes for models of 30 kW or below, or ten minutes for
models of 37 kW or above, before starting inspection. Further, check that the LED monitor and charging
lamp (on models of 37 kW or above) are unlit and that the DC link bus voltage between the P (+) and N
(-) terminals is lower than 25 VDC.

Otherwise, electric shock could occur.

• Maintenance, inspection, and parts replacement should be made only by qualified persons.

GENERAL PRECAUTIONS

v

Conformity with Low Voltage Directive in the EU

If installed according to the guidelines given below, inverters marked with CE can be considered to be compliant
with the Low Voltage Directive 73/23/EEC.

1. Be sure to earth the grounding terminal zG. Use an earth wire sized more than that of the power wires

used in the power dispatch system. Do not use a residual-current-operated protective device (RCD)* or
an earth leakage circuit breaker (ELCB)* as a sole mechanism of electric shock protection.

*With overcurrent protection.

2. Use an MCCB, RCD/ELCB or MC in conformity with EN or IEC standards.

3. When an RCD/ELCB is used for protection of electric shock caused by a direct or indirect contact to the
live parts, insert a type B RCD/ELCB in input lines (primary) of the inverter for the 3-phase 200 V or 400
V power source.

4. Use inverters in an environment that does not exceed pollution degree 2. If inverters are to be used in an
environment with pollution degree 3 or 4, place them in an enclosure of IP54 or above.

5. To protect human body from an electric shock caused by a contact to live parts, install inverters, AC
reactor and input /output filter in the enclosure of IP2X. In the case where human body easily contacts to
live parts, a top panel of the enclosure should be IP4X or higher.

6. Do not directly connect a copper wire to the grounding terminal. Use a crimp terminal with tin or equivalent
plating to connect the earth wire.

7. When using inverters at an altitude of more than 2000 m, note that the basic insulation applies to the
insulation degree of the control circuitry. At an altitude of more than 3000 m, inverters cannot be used.

vi

Conformity with Low Voltage Directive in the EU (continued)

8. Use the wires listed in EN60204 Appendix C.

Vibration

Noise

Explosion-proof
motors

When driving a 400V general-purpose motor with an inverter using
extremely long wires, damage to the insulation of the motor may occur.
Use an output circuit filter (OFL) if necessary after checking with the motor
manufacturer. Fuji motors do not require the use of output circuit filters
because of their reinforced insulation.

When the inverter is used to run a general-purpose motor, the temperature
of the motor becomes higher than when it is operated using a commercial
power supply. In the low-speed range, the cooling effect will be weakened,
so decrease the output torque of the motor.

When an inverter-driven motor is mounted to a machine, resonance may
be caused by the natural frequencies of the machine system.

Note that operation of a 2-pole motor at 60 Hz or higher may cause
abnormal vibration.

* The use of a rubber coupling or vibration dampening rubber is

recommended.

* Use the inverter's jump frequency control feature to skip the resonance

frequency zone(s).

When an inverter is used with a general-purpose motor, the motor noise
level is higher than that with a commercial power supply. To reduce noise,
raise carrier frequency of the inverter. Operation at 60 Hz or higher can
also result in higher noise level.

When driving an explosion-proof motor with an inverter, use a combination
of a motor and an inverter that has been approved in advance.

These motors have a larger rated current than general-purpose motors.
Select an inverter whose rated output current is greater than that of the
motor.

These motors differ from general-purpose motors in thermal
characteristics. Set a low value in the thermal time constant of the motor
when setting the electronic thermal function.

For motors equipped with parallel-connected brakes, their braking power
must be supplied from the primary circuit. If the brake power is connected
to the inverter's output circuit by mistake, the brake will not work.

Do not use inverters for driving motors equipped with series-connected
brakes.

If the power transmission mechanism uses an oil-lubricated gearbox or
speed changer/reducer, then continuous motor operation at low speed
may cause poor lubrication. Avoid such operation.

It is necessary to take special measures suitable for this motor type.
Contact your Fuji Electric representative for details.

Single-phase motors are not suitable for inverter-driven variable speed
operation. Use three-phase motors.

Use the inverter within the ambient temperature range from -10 to +50°C.

The heat sink of the inverter may become hot under certain operating
conditions, so install the inverter on nonflammable material such as metal.

Ensure that the installation location meets the environmental conditions
specified in Chapter 2, Section 2.1 "Operating Environment."

Do not turn the magnetic contactor (MC) in the primary circuit ON or OFF
more than once an hour as an inverter failure may result.

If frequent starts or stops are required during motor operation, use
(FWD)/(REV) signals or the RUN/STOP key.

The electronic thermal function of the inverter can protect the motor. The
operation level and the motor type (general-purpose motor, inverter motor)
should be set. For high-speed motors or water-cooled motors, set a small
value for the thermal time constant and protect the motor.

If you connect the motor thermal relay to the motor with a long wire, a
high-frequency current may flow into the wiring stray capacitance. This
may cause the relay to trip at a current lower than the set value for the
thermal relay. If this happens, lower the carrier frequency or use the output
circuit filter (OFL).

Do not mount power-factor correcting capacitors in the inverter’s primary
circuit. (Use the DC reactor to improve the inverter power factor.) Do not
use power-factor correcting capacitors in the inverter’s output (secondary)
circuit. An overcurrent trip will occur, disabling motor operation.

Do not connect a surge killer to the inverter's output (secondary) circuit.

Use of a filter and shielded wires is typically recommended to satisfy EMC
Directives.

If an overvoltage trip occurs while the inverter is stopped or operated under
a light load, it is assumed that the surge current is generated by open/close
of the power-factor correcting capacitor in the power system.

* Connect a DC reactor to the inverter.

Grounding Securely ground the inverter using the grounding terminal.

When checking the insulation resistance of the inverter, use a 500 V
megger and follow the instructions contained in Chapter 7, Section 7.5
"Insulation Test."

When using remote control, limit the wiring length between the inverter and
operator box to 20 m or less and use twisted pair or shielded wire.

If long wiring is used between the inverter and the motor, the inverter will
overheat or trip as a result of overcurrent (high-frequency current flowing
into the stray capacitance) in the wires connected to the phases. Ensure
that the wiring is shorter than 50 m. If this length must be exceeded, lower
the carrier frequency or mount an output circuit filter (OFL).

Select wires with a sufficient capacity by referring to the current value or
recommended wire size.

When several inverters drive motors, do not use one multicore cable in
order to connect several inverters with motors.

1.3 Transportation

• When carrying an inverter, always support its bottom at the front and rear sides with both hands. Do not hold
covers or individual parts only. You may drop the inverter or break it.

• When hoisting an inverter with hoisting holes, hook or rope the 4 holes evenly.

1.4 Storage Environment

1.4.1 Temporary storage

Store the inverter in an environment that satisfies the requirements listed in Table 1.1.

Table 1.1 Environmental Requirements for Storage and Transportation

Item Requirements

Storage temperature *1 -25 to +70°C
Relative humidity 5 to 95% *2

Atmosphere

1

*

Assuming a comparatively short storage period (e.g., during transportation or the like).

2

Even if the humidity is within the specified requirements, avoid such places where the inverter will be subjected to

*

sudden changes in temperature that will cause condensation to form.

The inverter must not be exposed to dust, direct sunlight, corrosive or flammable gases,
oil mist, vapor, water drops or vibration. The atmosphere must contain only a low level of
salt. (0.01 mg/cm

86 to 106 kPa (in storage) Atmospheric pressure

Precautions for temporary storage

A location where the inverter is not subject to abrupt changes in
temperature that would result in the formation of condensation or ice.

2

or less per year)

(1) Do not leave the inverter directly on the floor.

(2) If the environment does not satisfy the specified requirements, wrap the inverter in an airtight vinyl sheet or

the like for storage.

(3) If the inverter is to be stored in an environment with a high level of humidity, put a drying agent (such as silica

gel) in the airtight package described in item (2).

1.4.2 Long-term storage

The long-term storage methods for the inverter vary largely according to the environment of the storage site.
General storage methods are described below.

(1) The storage site must satisfy the requirements specified for temporary storage.
However, for storage exceeding three months, the ambient temperature should be within the range from -10

to +30 °C. This is to prevent the electrolytic capacitors in the inverter from deteriorating.

(2) The inverter must be stored in a package that is airtight to protect it from moisture. Include a drying agent

inside the package to maintain the relative humidity inside the package to within 70%.

(3) If the inverter has been installed in the equipment or control board at a construction site where it may be

subjected to humidity, dust or dirt, then remove the inverter and store it in a suitable environment specified in
Table 1.1.

Precautions for storage over 1 year

If the inverter will not be powered on for a long time, the property of the electrolytic capacitors may deteriorate.
Power the inverters on once a year and keep them on for 30 to 60 minutes. Do not connect the inverters to motors
or run the motor.

(Note 1) When inverters are mounted
side-by-side without any gap between them
(5.5 kW or less), the ambient temperature
should be within the range from -10 to
+40°C.

(Note 2) Do not install the inverter in an
environment where it may be exposed to
cotton waste or moist dust or dirt which will
clog the heat sink in the inverter. If the
inverter is to be used in such an
environment, install it in the enclosure of
your system or other dustproof containers.

(Note 3) If you use the inverter in an
altitude above 1000 m, you should apply an
output current derating factor as listed in
Table 2.2.

2.2 Installing the Inverter

(1) Mounting base

The temperature of the heat sink will rise up to approx. 90°C during
operation of the inverter, so the inverter should be mounted on a
base made of material that can withstand temperatures of this level.

Install the inverter on a base constructed from metal or other
non-flammable material.

A fire may result with other material.

(2) Clearances

Ensure that the minimum clearances indicated in Figure 2.1 are
maintained at all times. When installing the inverter in the enclosure
of your system, take extra care with ventilation inside the enclosure
as the temperature around the inverter will tend to increase. Do not
install the inverter in a small enclosure with poor ventilation.

 When mounting two or more inverters

Horizontal layout is recommended when two or more inverters are
to be installed in the same unit or enclosure. If it is necessary to
mount the inverters vertically, install a partition plate or the like
between the inverters so that any heat radiating from an inverter will
not affect the one/s above. As long as the ambient temperature is
40°C or lower, inverters can be mounted side-by-side without any
gap between them (only for inverters with a capacity of 5.5 kW o
below).

 When employing external cooling

At the shipment time, the inverter is set up for mount inside your
equipment or enclosure so that cooling is done all internally.

To improve cooling efficiently, you can take the heat sink out of
the equipment or the enclosure (as shown on the right) so that
cooling is done both internally and externally (this is called
"external cooling").

In external cooling, the heat sink, which dissipates about 70% of
the total heat (total loss) generated into air, is situated outside the
equipment or the enclosure. As a result, much less heat is
radiated inside the equipment or the enclosure.

To take advantage of external cooling, you need to use the
external cooling attachment option for inverters with a capacity of
30 kW or below, or simply re-position the mounting bases for the
cooling unit for inverters with a capacity of 37 kW or above.

In an environment with high humidity or a lot of fibrous dust,
however, do not use external cooling in an environment with high
humidity or a lot of fibrous dust, which tends to clog the heat sink.

 For details, refer to the Mounting Adapter for External

Cooling "PB-F1" Installation Manual (INR-SI47-0880) and
FRENIC-Eco User’s Manual (MEH456).

Figure 2.2 External Cooling

Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter or from accumulating on the heat sink.

This may result in a fire or accident.

2-2

To utilize external cooling for inverters with a capacity of 37 kW or above, change the position of the top and
bottom mounting bases from the edge to the center of the inverter as illustrated in Figure 2.3.

Screws differ in size, length and count for each inverter. Be sure to refer to the table below.

(3) Mounting direction

Mount the inverter vertically to the mounting surface and fix it securely with four screws or bolts so that the logo
"FRENIC-Eco" can be seen from the front.

Do not mount the inverter upside down or horizontally. Doing so will reduce the heat dissipation
efficiency of the inverter and cause the overheat protection function to operate, so the inverter will not
run.

(4) Solving abnormal vibration after installation

If any vibration in the surroundings reaches the inverter and causes abnormal vibration to the cooling fan(s) or
the keypad, fix them firmly using the fixing screws provided as accessories.

2.3.5 Wiring precautions

Follow the rules below when performing wiring for the inverter.

(1) Make sure that the source voltage is within the rated voltage range specified on the nameplate.
(2) Be sure to connect the three-phase power wires to the main circuit power input terminals L1/R, L2/S and

L3/T of the inverter. If the power wires are connected to other terminals, the inverter will be damaged when
the power is turned on.

(3) Always connect the grounding terminal to prevent electric shock, fire or other disasters and to reduce

electric noise.

(4) Use crimp terminals covered with insulated sleeves for the main circuit terminal wiring to ensure a reliable

connection.

(5) Keep the power supply wiring (primary circuit) and motor wiring (secondary circuit) of the main circuit, and

control circuit wiring as far away as possible from each other.

• When wiring the inverter to the power source, insert a recommended molded case circuit breaker
(MCCB) or earth leakage circuit breaker (ELCB) (with overcurrent protection) in the path of each pair
of power lines to inverters. Use the devices recommended ones within the related current range.

• Use wires in the specified size.

• Tighten terminals with specified torque.

Otherwise, fire could occur.

• Do not connect a surge killer to the inverter's output circuit.

• Do not use one multicore cable in order to connect several inverters with motors.

Doing so could cause fire.

• Ground the inverter in compliance with the national or local electric code.

Otherwise, electric shock or fire could occur.

• Qualified electricians should carry out wiring.

• Be sure to perform wiring after turning the power off.

Otherwise, electric shock could occur.

• Be sure to perform wiring after installing the inverter.

Otherwise, electric shock or injuries could occur.

• Ensure that the number of input phases and the rated voltage of the product match the number of
phases and the voltage of the AC power supply to which the product is to be connected.

• Do not connect the power source wires to output terminals (U, V, and W).

Doing so could cause fire or an accident.

Grounding terminals ( G)

Be sure to ground either of the two grounding terminals for safety and noise reduction. The inverter is designed
to use with a safety grounding to avoid electric shock, fire and other disasters.

Grounding terminals should be grounded as follows:

1) Ground the inverter in compliance with the national or local electric code.

2) Use a thick grounding wire with a large surface area and keep the wiring length as short as possible.

Inverter output terminals, U, V, W and grounding terminals ( G)

Inverter’s output terminals should be connected as follows:

1) Connect the three wires of the 3-phase motor to terminals U, V, and W, aligning phases each other.

2) Connect the secondary grounding wire to the grounding terminal (

• The wiring length between the inverter and motor should not exceed 50 m, when they are
connected directly. If the wiring length exceeds 50 m, an output circuit filter (option) should be
inserted. (E.g. total power cable length is 400 m as shown in the figure below.)

• Do not use one multicore cable to connect several inverters with motors even if some possible
combinations of inverters and motors are considered.

G).

• Do not connect a power factor correcting capacitor or surge absorber to the inverter’s output lines
(secondary circuit).

• If the wiring length is long, the stray capacitance between the wires will increase, resulting in an
outflow of the leakage current. It will activate the overcurrent protection, increase the leakage
current, or will not assure the accuracy of the current display. In the worst case, the inverter could
be damaged.

• If more than one motor is to be connected to a single inverter, the wiring length should be the sum
of the length of the wires to the motors.

• If an output circuit filter is installed in the inverter or the wires between the motor and the inverte
are too long, the actual voltage applied to the motor would drop measurably because of the voltage
drop over the filter or the wires. As a result, the output current may fluctuate because of an
insufficient voltage.
In such installations, set the voltage on the higher side, by setting the function code F37 (Load
Selection/Auto torque Boost/Auto energy Saving Operation) to "1: Variable torque load increasing
in proportion to square of speed" (Higher start-up torque required), or selecting a non-linear V/
pattern (using the function codes H50 and H51 (Non-linear V/f pattern (Frequency and Voltage)).

• Use an output circuit (secondary) filter of OFL-

Driving 400 V series motor

• If a thermal relay is installed in the path between the inverter and the motor to protect the motor
from overheating, the thermal relay may malfunction even with a wiring length shorter than 50 m.
In this situation, add an output circuit filter (option) or lower the carrier frequency (Function code
F26).

• If the motor is driven by a PWM-type inverter, surge voltage that is generated by switching the
inverter component may be superimposed on the output voltage and may be applied to the motor
terminals. Particularly if the wiring length is long, the surge voltage may deteriorate the insulation
resistance of the motor. Consider any of the following measures.

- Use a motor with insulation that withstands the surge voltage. (All Fuji standard motors feature

insulation that withstands the surge voltage.)

- Connect an output circuit filter (option) to the output terminals (secondary circuits) of the

inverter.

- Minimize the wiring length between the inverter and motor (10 to 20 m or less).

DC reactor terminals, P1 and P (+)

1) Remove the jumper bar from terminals P1 and P(+).

2) Connect a DC reactor (option) to terminals P1 and P(+).

• The wiring length should be 10 m or below.

• Do not remove the jumper bar if a DC reactor is not going to be used.

• An inverter with a capacity of 75 kW or above is equipped with a DC reactor as standard. Be sure
to connect the DC reactor except when an optional converter is connected to the inverter.

Switching connectors

 Power switching connectors (CN UX) (for the models of 400 V series 55 kW or above)

An inverter of 400 V series 55 kW or above is equipped with a set of switching connectors (male) which should
be configured according to the power source voltage and frequency. By factory default, a jumper (female
connector) is set at U1. If any of the conditions listed in Table 2.9 is met to the main power inputs (L1/R, L2/S,
L3/T), or to the auxiliary power input terminals (R1, T1) for the fans, re-install the jumper to U2; otherwise, leave
it at U1. For the procedure for re-installing a jumper, refer to Figures 2.14 to 2.16.

 Fan power supply switching connectors (CN R) and (CN W) (for models of 45 kW or above (200 V series) or

55 kW or above (400 V series))

The standard FRENIC-Eco series of inverters also accept DC-linked power input in combination with a power
regenerative PW M converter (RHC series). Even when you drive the inverter with a DC-linked power, however,
you also need to supply AC power for models of 45 kW or above (200 V series) or 55 kW or above (400 V
series), since it contains components such as AC fans that are driven by AC power. In this case, re-install the
connectors (CN R) and (CN W) to the NC and FAN positions respectively and supply the power to the
auxiliary power input terminals (R1, T1).

For the actual procedure, refer to Figures 2.14 to 2.16 below.

On the fan power supply switching connectors (CN R) and (CN W), the jumpers are installed
at FAN and NC positions respectively by factory default. Do not relocate the jumper unless you
drive the inverter with a DC-linked power supply.

If there is a mistake in the installation of the jumpers for the switching connectors, the cooling fan will
not run, causing a heat sink overheating alarm "

each other.

* With overcurrent protection

It is recommended that a magnetic contactor be inserted that can be manually activated. This is to
allow you to disconnect the inverter from the power supply in an emergency (e.g., when the protective
function is activated) so as to prevent a failure or accident from causing the secondary problems.

Auxiliary power input terminals R0 and T0 for the control circuit

In general, the inverter will run normally without power supplied to the auxiliary power input for the control circuit.
However, if you share the input power for the control circuit with that for the main circuit, you would be lost when,
in the event of an error or alarm, you turn OFF the magnetic contactor between the inverter and the commercial
power supply. If the magnetic contactor is turned OFF, the input power to the control circuit is shut OFF, causing
the alarm signals (30A/B/C) to be lost and the display on the keypad to disappear. To secure input power to the
control circuit at all times, supply the power from the primary side of the magnetic contactor to control power
auxiliary input terminals R0 and T0.

Auxiliary power input terminals R1 and T1 for the fan

Inverters, 200 V series 45 kW or above and 400 V series 55 kW or above are equipped with these terminals R1
and T1. Only if the inerter works with the DC linked power input whose source is a power regenerative PW M
converter (e.g. RHC series), these terminals are used to feed power to the fans while they are not used in any
power system of ordinary configuration. The fan power is:

Single phase 200 to 220 VAC/50 Hz, 200 to 230 VAC/60 Hz for 200 V series 45 kW or above
Single phase 380 to 440 VAC/50 Hz. 380 to 480 VAC/60 Hz for 400 V series 55 kW or above

2-21

2.3.7 Wiring for control circuit terminals

In general, sheaths and covers of the control signal cables and wires are not specifically designed to
withstand a high electric field (i.e., reinforced insulation is not applied). Therefore, if a control signal cable or
wire comes into direct contact with a live conductor of the main circuit, the insulation of the sheath or the
cover might break down, which would expose the signal wire to a high voltage of the main circuit. Make sure
that the control signal cables and wires will not come into contact with live conductors of the main circuit.

Failure to observe these precautions could cause electric shock and/or an accident.

Noise may be emitted from the inverter, motor and wires.

Take appropriate measure to prevent the nearby sensors and devices from malfunctioning due to such
noise.

An accident could occur.

Table 2.10 lists the symbols, names and functions of the control circuit terminals. The wiring to the control circuit
terminals differs depending upon the setting of the function codes, which reflects the use of the inverter. Route
wires properly to reduce the influence of noise, referring to the notes on the following pages.

- Since low level analog signals are handled, these signals are especially susceptible to the external
noise effects. Route the wiring as short as possible (within 20 m) and use shielded wires. In
principle, ground the shielded sheath of wires; if effects of external inductive noises are
considerable, connection to terminal [11] may be effective. As shown in Figure 2.18, ground the
single end of the shield to enhance the shielding effect.

- Use a twin contact relay for low level signals if the relay is used in the control circuit. Do not connect
the relay's contact to terminal [11].

- When the inverter is connected to an external device outputting the analog signal, a malfunction
may be caused by electric noise generated by the inverter. If this happens, according to the
circumstances, connect a ferrite core (a toroidal core or an equivalent) to the device outputting the
analog signal and/or connect a capacitor having the good cut-off characteristics for high frequency
between control signal wires as shown in Figure 2.19.

- Do not apply a voltage of +7.5 VDC or higher to terminal [C1]. Doing so could damage the internal

2.3.8 Setting up slide switches and handling control circuit terminal symbol plate

Before changing the switches or touching the control circuit terminal symbol plate, turn OFF the power and
wait more than five minutes for models of 30 kW or below, or ten minutes for models of 37 kW or above.
Make sure that the LED monitor and charging lamp (on models of 37 kW or above) are turned OFF. Further,
make sure, using a multimeter or a similar instrument, that the DC link bus voltage between the terminals P
(+) and N (-) has dropped below the safe voltage (+25 VDC).

An electric shock may result if this warning is not heeded as there may be some residual electric
charge in the DC bus capacitor even after the power has been turned off.

 Setting up the slide switches

Switching the slide switches located on the control PCB allows you to customize the operation mode of the
analog output terminals, digital I/O terminals, and communications ports. The locations of those switches are
shown in Figure 2.29.

To access the slide switches, remove the front and terminal block covers so that you can watch the control PCB.
For models of 37 kW or above, open also the keypad enclosure.

Close the control circuit terminal symbol plate since the plate being opened interferes with switching of some
switches.

 For details on how to remove the front cover, terminal block cover, and keypad enclosure, refer to Section

2.3.1, "Removing and mounting the terminal block (TB) cover and the front cover" and Chapter 1, Section

2.5 Cautions Relating to Harmonic Component, Noise, and Leakage Current

(1) Harmonic component

Input current to an inverter includes a harmonic component, which may affect other loads and power factor
correcting capacitors that are connected to the same power source as the inverter. If the harmonic component
causes any problems, connect a DC reactor (option) to the inverter. It may also be necessary to connect an AC
reactor to the power factor correcting capacitors.

(2) Noise

If noise generated from the inverter affects other devices, or that generated from peripheral equipment causes
the inverter to malfunction, follow the basic measures outlined below.

1) If noise generated from the inverter affects the other devices through power wires or grounding wires:

- Isolate the grounded metal frames of the inverter from those of the other devices.

- Connect a noise filter to the inverter power wires.

- Isolate the power system of the other devises from that of the inverter with an insulated transformer.

2) If induction or radio noise generated from the inverter affects other devices through power wires or
grounding wires:

- Isolate the main circuit wires from the control circuit wires and other device wires.

- Put the main circuit wires through a metal conduit and connect the pipe to the ground near the inverter.

- Install the inverter onto the metal switchboard and connect the whole board to the ground.

- Connect a noise filter to the inverter power wires.

3) When implementing measures against noise generated from peripheral equipment:

- For the control signal wires, use twisted or shielded-twisted wires. When using shielded-twisted wires,
connect the shield of the shielded wires to the common terminals of the control circuit or ground.

- Connect a surge absorber in parallel with a coil or solenoid of the magnetic contactor.

(3) Leakage current

Harmonic component current generated by insulated gate bipolar transistors (IGBTs) switching on/off inside the
inverter becomes leakage current through stray capacitors of inverter input and output wires or a motor. If any of
the problems listed below occur, take an appropriate measure against them.

Table 2.12 Leakage Current Countermeasures

Problem Measures

An earth leakage circuit
breaker* that is connected to
the input (primary) has tripped.

* With overcurrent protection

An external thermal relay was
activated.

1) Decrease the carrier frequency.

2) Make the wires between the inverter and motor shorter.

3) Use an earth leakage circuit breaker that has a longer sensitive current than
one currently being used.

4) Use an earth leakage circuit breaker that features measures against
harmonic component (Fuji SG and EG series).

1) Decrease the carrier frequency.

2) Increase the settling current of the thermal relay.

3) Use the electronic thermal relay built in the inverter, instead of an external
thermal relay.

3.3.2 Setting up frequency and PID process commands

You can set up the desired frequency and PID process commands by using the

and keys on the keypad. It
is also possible to set up the frequency command as load shaft speed, motor speed or speed (%) by setting
function code E48.

 Setting up a frequency command

Using the

/ key again. The new setting will be auto­matically saved into the inverter's internal memory and retained even when the power is off. When the power
is turned on next time, the setting will be used as an initial reference frequency.

• The frequency command can be saved either automatically as mentioned above or by pressing the
key. You can choose either way using function code E64.

• If you have set function code F01 to "0: Enable

/ keys on keypad" but have selected a fre­quency command other than frequency command 1 (i.e., frequency command 2, frequency command
via communication, or multistep frequency command), then the

/ keys are disabled to change
the current frequency command even in Running mode. Pressing either of these keys just displays
the current reference frequency.

• When you start specifying or changing the frequency command or any other parameter with the

/

key, the lowest digit on the display blinks and starts changing. As you are holding down the key,

blinking will gradually move to the upper digit places and the upper digits will be changeable.

• If you press the

/ key once and then hold down the key for more than 1 second after the
lowest digit starts blinking, blinking will move to the next upper digit place to allow you to change the
value of that digit (cursor movement). This way you can easily change the values of the higher digits.

• By setting function code C30 to "0: Enable
mand 2, you can also specify or change the frequency command in the same manner using the

key.

You can set up a frequency command not only with the frequency (Hz) but also with other menu items (Motor
speed, load shaft speed, and speed (%)) depending on the setting of function code E48 (= 3, 4, or 7) "Speed
monitor items" as shown in Table 3.3.

3-5

 Make setting under PID control

To enable PID control, you need to set function code J01 to 1 or 2.

Under the PID control, the items that can be set or checked with the

and keys are different from those
under regular frequency control, depending upon the current LED monitor setting. If the LED monitor is set to the
speed monitor (E43 = 0), you can access manual speed commands (Frequency command) with the

and

keys; if it is set to any other, you can access the PID process command with those keys.

Refer to the FRENIC-Eco User's Manual (MEH456), Chapter 4, Section 4.9, "PID Frequency Command

Generator" for details on the PID control.

Setting the PID process command with the

/ keys on keypad."

(2) Set the LED monitor to something other than the speed monitor (E43 = 0) when the inverter is in Running

mode. When the keypad is in Programming or Alarm mode, you cannot modify the PID process command
with the

/ key. To enable the PID process command to be modified with the

key, first switch to

/

Running mode.

(3) Press the

/ key to have the PID process command displayed. The lowest digit will blink on the LED

monitor.

(4) To change the PID process command, press the

/ key again. The PID process command you have
specified will be automatically saved into the inverter’s internal memory. It is kept there even if you temporarily
switch to another means of specifying the PID process command and then go back to the means of specifying
the PID process command via the keypad. Also, it is kept there even while the inverter is powered off, and will
be used as the initial PID process command next time the inverter is powered on.

• Even if multistep frequency is selected as the PID process command ((SS4) = ON), you still can set
the process command using the keypad.

• When function code J02 is set to any value other than 0, pressing the

/ key displays, on the

7-segment LED monitor, the PID command currently selected, while you cannot change the setting.

• On the 7-segment LED monitor, the decimal point of the lowest digit is used to characterize what is
displayed. The decimal point of the lowest digit blinks when a PID process command is displayed; the
decimal point lights when a PID feedback value is displayed.

 For the details on operations with function code F02, refer to Chapter 5 “FUNCTION CODES.”

When the keypad is in use for specifying the frequency settings or driving the motor, do not disconnect
the keypad from the inverter when the motor is running. Doing so may stop the inverter.

3-8

 Remote and local modes

The inverter can be operated either in remote or local mode. In remote mode that applies to ordinary operation, the
inverter is driven under the control of the data settings stored in the inverter, whereas in local mode that applies to
maintenance operation, it is separated from the control system and is driven manually under the control of the
keypad.

• Remote mode: The run and frequency commands are selected by source switching signals including function

codes, run command 2/1 signals, and communications link operation signal.

• Local mode: The command source is the keypad, regardless of the settings specified by function codes. The

keypad takes precedence over the settings specified by run command 2/1 signals or commu­nications link operation signal.

Run commands from the keypad in local mode

key stops the motor.

Switching between remote and local modes

The remote and local modes can be switched by a digital input signal provided from the outside of the inverter.

To enable the switching, you need to assign (LOC) as a digital input signal to any of terminals [X1] to [X5] by
setting "35" to any of E01 to E05, E98 and E99. By factory default, (LOC) is assigned to [X5].

Switching from remote to local mode automatically inherits the frequency settings used in remote mode. If the
motor is running at the time of the switching from remote to local, the run command is automatically turned on so
that all the necessary data settings will be carried over. If, however, there is a discrepancy between the settings
used in remote mode and ones made on the keypad (e.g., switching from the reverse rotation in remote mode to
the forward rotation only in local mode), the inverter automatically stops.

The transition paths between remote and local modes depend on the current mode and the value (on/off) of (LOC),
as shown in the status transition diagram given below. Also, refer to Table 3.7 " Run Commands from the Keypad
in Local Mode" for details.

3.4 Programming Mode

The Programming mode provides you with these functions--setting and checking function code data, monitoring
maintenance information and checking input/output (I/O) signal status. The functions can be easily selected with
the menu-driven system. Table 3.8 lists menus available in Programming mode. The leftmost digit (numerals) of
each letter string on the LED monitor indicates the corresponding menu number and the remaining three digits
indicate the menu contents.

When the inverter enters Programming mode from the second time on, the menu selected last in Programming
mode will be displayed.

With the FRENIC-Eco, digital input terminals [FWD] and [REV] are assigned to bit 0 and bit 1, respectively.
Terminals [X1] through [X5] are assigned to bits 2 through 6. The bit is set to "1" when the corresponding input
terminal is short-circuited (ON)*, and is set to "0" when it is open (OFF). For example, when [FWD] and [X1] are on
(short-circuited) and all the others are off (open),

Digital output terminal [Y1], [Y2] and [Y3] are assigned to bits 0 to 2. Each bit is set to "1" when the terminal is
short-circuited with [CMY], and to "0" when it is open. The status of the relay contact output terminal [30A/B/C] is
assigned to bit 8. It is set to "1" when the circuit between output terminals [30A] and [30C] is closed and to "0"
when the circuit between [30B] and [30C] is closed. The status of the relay contact output [Y5A/C] is assigned to

When the alarm code is displayed, you may check various running status information (output frequency and
output current, etc.) by pressing the

key. The item number and data for each running information will be

displayed alternately.

Further, you can view various pieces of information on the running status of the inverter using the

/ key. The
information displayed is the same as for Menu #6 "Alarm Information" in Programming mode. Refer to Table 3.19
in Section 3.4.7, "Reading alarm information."

Pressing the

key while the running status information is displayed returns the display to the alarm codes.

When the running status information is displayed after removal of the alarm cause, pressing the key
twice returns to the alarm code display and releases the inverter from the alarm state. This means that
the motor starts running if a run command has been received by this time.

 Switching to Programming mode

You can also switch to Programming mode by pressing

+ keys simultaneously with the alarm displayed,

and modify the function code data.

Chapter 4 RUNNING THE MOTOR

4.1 Running the Motor for a Test

4.1.1 Inspection and preparation prior to powering on

Check the following prior to starting powering on.

(1) Check if connection is correct.

Especially check if the power wires are connected to the inverter input terminals L1/R, L2/S and L3/T, and

output terminals U, V and W respectively and that the grounding wires are connected to the ground
electrodes correctly. Note that FRENIC-Eco series inverter is designed for three phase input and driving three
phase motors.

• Do not connect power supply wires to the inverter output terminals U, V, and W. Otherwise, the inverter may
be broken if you turn the power ON.

• Be sure to connect the grounding wires of the inverter and the motor to the ground electrodes.

Otherwise, electric shock may occur.

(2) Check for short circuits between terminals and exposed

live parts and ground faults.

(3) Check for loose terminals, connectors and screws.

(4) Check if the motor is separated from mechanical

equipment.

(5) Turn the switches OFF so that the inverter does not start o

operate erroneously at power-on.

(6) Check if safety measures are taken against runaway of the

system, e.g., a defense to protect people from
unexpectedly approaching your power system.

4.1.2 Turning ON power and checking

Figure 4.1 Connection of Main Circuit Terminals

• Be sure to install the covers for both the main circuit terminal block, control circuit terminal block and the front
cover if any before turning the power ON.

Do not remove any cover while powering on.

• Do not operate switches with wet hands.

Otherwise electric shock could occur.

Turn the power ON and check the following points. This is a case
when no function code data is changed from the factory setting.

(1) Check if the LED monitor displays

frequency command is 0 Hz) that is blinking. (See Figure 4.2.)

If the LED monitor displays numbers except

as the frequency command.

(2) Check if a built-in cooling fan rotates.

(When only the auxiliary power is fed while the main power
is turned OFF, the cooling fan does not rotate. For the
inverter of 1.5 kW or below no cooling fan is mounted.)

4.1.3 Preparation before running the motor for a test--Setting function code data

Before starting running the motor, set function code data specified in Table 4.1 to the motor ratings and your
system design values. For the motor, check the rated values printed on the nameplate of the motor. For your
system design values, ask system designers about them.

For details about how to change function code data, refer to Chapter 3, Section 3.4.1 "Setting up function



codes quickly." Refer to the function code H03 in Chapter 5 "FUNCTION CODES" for the factory default
setting of motor parameters. If any of them is different from the default setting, change the function code
data.

In any of the following cases, the default settings may not produce the best results for auto torque boost,
torque calculation monitoring, or auto energy saving, since the standard settings of motor parameters fo
Fuji motors are not applicable. Tune the motor parameters according to the procedure set forth below.

• The motor to be driven is not a Fuji product or is a non-standard product.

• The cabling between the motor and the inverter is long.

• A reactor is inserted between the motor and the inverter.

＜Tuning procedure＞

1) Preparation

Referring to the rating plate on the motor, set the following function codes to their nominal ratings:

• F04: Base frequency

• F05: Rated voltage (at Base frequency)

• P02: Rated capacity

• P03: Rated current

2) Selection of Tuning Process

Check the situation of the machine system and choose between "Tuning while the motor is stopped (P04
= 1)" and "Tuning while the motor is running (P04 = 2)." In the case of "Tuning while the motor is running
(P04 = 2)," also adjust the acceleration and deceleration times (F07 and F08) and set the rotation
direction properly so that it matches the actual rotation direction of the machine system.

Action Choose the process when:

Measure %R1 and %X while
the motor is stopped.

Measure %R1 and %X while
the motor is stopped, and
later no-load current while
the motor is running. (At
50% of the Base frequency).

The motor cannot be rotated, or
more than 50% of the rated load
would be applied on the motor if
rotated.

Even if the motor is rotated, it is
safe and the load applied on the
motor would be no more than 50%
of the rating. (If you do the tuning
with no load, you will get the
highest precision.)

Upon completion of the tuning, the primary resistance %R1 will be automatically saved into P07, the
leakage reactance %X into P08, and the no-load current into P06.

4-2

3) Preparation of Machine System

Perform appropriate preparations on the motor and its load, such as disengaging the coupling and
deactivating the safety device.

4) Perform tuning

Set function code P04 to "1" or "2" and press the key. (The blinking of 1 or 2 on the LED monitor

will slow down.)

Enter a Run command for the rotation direction you have chosen. The factory default setting is

"forward rotation upon pressing the

key on the keypad." To switch to reverse rotation, change

the setting of function code F02.

The display of 1 or 2 stays lit, and tuning takes place while the motor is stopped.

(Maximum tuning time: approximately 40 (s).)

If the function code P04 = 2, the motor is accelerated to approximately 50% of the base frequency

and then tuning takes place. Upon completion of measurements, the motor will coast-to-stop.

(Estimated tuning time: Acceleration time + 10 (s) + Deceleration time)

If the terminal signal (FWD) or (REV) is selected as the Run command (F02 = 1),

will appear

upon completion of the measurements.

The Run command is turned OFF and the tuning completes, with the next function code

p06

displayed on the keypad (the Run command given through the keypad or the communications link is
automatically turned OFF).

 Errors during tuning

Improper tuning would negatively affect the operation performance and, in the worst case, could even
cause hunting or deteriorate precision. Therefore, if the inverter finds any abnormality in the results of the

er7

tuning or any error in the process of the tuning, it will display

and discard the tuning data.

Listed below are the abnormal or error conditions that can be recognized during tuning.

Abnormal/error condition Description

Abnormal result of tuning

Abnormal output current

Sequence error

Limitation exceeded

Other alarm condition

An inter-phase imbalance has been detected;

Tuning has resulted in an abnormally high or low value of a parameter.

An abnormally high current has been caused during tuning.

During tuning, the Run command has been turned OFF, or forced STOP,
coast-to-stop command (BX), dew condensation protection (DWP), or a
similar abnormal command has been received.

During tuning, a certain limitation has been reached or exceeded;

The maximum output frequency or the peak limiter for output frequency has
been reached or exceeded.

An undervoltage or an alarm has been occurred.

If any of these conditions has occurred, either eliminate the abnormal or error factor(s) and perform
tuning again, or contact your Fuji Electric representative.

If a filter other than Fuji optional output filter (OFL--4A) is connected to the inverter's
output (secondary) circuit, the result of tuning can be unpredictable. When you replace an
inverter, take note of the old inverter’s settings for the primary resistance %R1, the leakage
reactance %X, and the no-load current, and set those values to the new inverter’s function
codes.

4.1.4 Test run

If the user set the function codes wrongly or without completely understanding this Instruction Manual and the
FRENIC-Eco User's Manual (MEH456), the motor may rotate with a torque or at a speed not permitted for the
machine.

Accident or injury may result.

Follow the descriptions of the previous Section 4.1.1, "Inspection and preparation prior to powering on" to Section

4.1.3, "Preparation before running the motor for a test," and begin test-driving of the motor.

If any abnormality is found to the inverter or motor, immediately stop operation and determine the cause
referring to Chapter 6, "TROUBLESHOOTING."

Chapter 5 FUNCTION CODES

5.1 Function Code Tables

Function codes enable the FRENIC-Eco series of inverters to be set up to match your system requirements.

Each function code consists of a 3-letter alphanumeric string. The first letter is an alphabet that identifies its group
and the following two letters are numerals that identify each individual code in the group. The function codes are
classified into eight groups: Fundamental Functions (F codes)
Functions of Frequency (C codes), Motor Parameters (P codes), High Performance Functions (H codes),
Application Functions (J codes)
of each function code, set data to the function code.

This manual does not contain the descriptions of Option Function (o codes). For Option Function (o codes), refer
to the instruction manual for each option.

The following descriptions supplement those given in the function code tables on page 5-3 and subsequent pages.

Copying data

The keypad is capable of copying of the function code data stored in the inverter's memory into the keypad's
memory (refer to Menu #7 "Data copying" in Programming mode). With this feature, you can easily transfer the
data saved in a source inverter to other destination inverters.

If the specifications of the source and destination inverters differ, some code data may not be copied to ensure
safe operation of your power system. Whether data will be copied or not is detailed with the following symbols in
the "Data copying" column of the function code tables given below.

Y: Will be copied unconditionally.
Y1: Will not be copied if the rated capacity differs from the source inverter.
Y2: Will not be copied if the rated input voltage differs from the source inverter.
N: Will not be copied. (The function code marked with "N" is not subject to the Verify operation, either.)

If necessary, set up uncopied code data manually and individually.

For details of how to set up or edit function codes, refer to Chapter 3 "OPERATION USING THE
KEYPAD."

 Using negative logic for programmable I/O terminals

The negative logic signaling system can be used for the digital input and output terminals by setting the function
code data specifying the properties for those terminals. Negative logic refers to the inverted ON/OFF (logical value
1 (true)/0 (false)) state of input or output signal. An ON-active signal (the function takes effect if the terminal is
short-circuited.) in the normal logic system is functionally equivalent to OFF-active signal (the function takes effect
if the terminal is opened.) in the negative logic system. An ON-active signal can be switched to OFF-active signal,
and vice verse, with the function code data setting.

To set the negative logic system for an I/O signal terminal, enter data of 1000s (by adding 1000 to the data for the
normal logic) in the corresponding function code and then press the

The table below shows that the coast-to-stop command (BX) is assigned to the terminal [X1] using the function
