Japanese Guideline for Suppressing Harmonics in Home Electric and Gen­eral-purpose Appliances

Fuji three-phase 200 V class series of inv erters with a capacity of 3.7 (4.0) kW or less, single-phase
200 V class series with 2.2 kW or less, and single-phase 100 V class series with 0.75 kW or less
were once subject to the "Japanese Guideline for Suppressing Harmonics in Home Electric and
General-purpose Appliances" (established in September 1994 and revised in October 1999), pub­lished by the Ministry of International Trade and Industry (currently the Ministry of Economy, Trade
and Industry (METI)).

Since the revision of the guideline in January 2004, however, these inverters have no longer been
subject to the guideline. The individual inverter manu factur ers hav e v olunt arily employ ed harmoni cs
suppression measures.

As our measure, it is recommended that DC reactors (DCRs) authorized in this manual be con­nected to the FRENIC-Mini series of inverters.

When using DCRs not authorized in this manual, however, consult your Fuji Electric representative
for the detailed specifications.

Japanese Guideline for Suppressing Harmonics by Customers Receiving
High Voltage or Special High Voltage

 Safety precautions

Read this manual thoroughly before proceeding with installation, connections (wiring), operation, or
maintenance and inspection. Ensure you have sound knowledge of the device and familiarize
yourself with all safety information and precautions before proceeding to operate the inverter.

Safety precautions are classified into the following two categories in this manual.

Failure to heed the information indicated by this symbol may
lead to dangerous conditions, possibly resulting in death or
serious bodily injuries.

Failure to heed the information indicated by this symbol may
lead to dangerous conditions, possibly resulting in minor or
light bodily injuries and/or substantial property damage.

Failure to heed the information contained under the CAUTION title can also result in serious con­sequences. These safety precautions are of utmost importance and must be observed at all times.

Application

• FRENIC-Mini is designed to drive a three-phase induction motor and three-phase per­manent magnet synchronous motor (PMSM). Do not use it for single-pha se motors or for
other purposes.

Fire or an accident could occur.

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

• Though FRENIC-Mini 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.

iv

• 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 box es.

Doing so could cause injuries.

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.

• When wiring the inverter to the power supply of 500 kVA or more, be sure to connect an
optional DC reactor (DCR).

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.

• Be sure to connect the grounding wires without fail.

Otherwise, electric shock or fire could occur.

• Qualified electricians should carry out wiring.

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

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

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).

• Do not insert a braking resistor between terminals P (+) and N (-), P1 and N (-), P (+) and
P1, DB and N (-), or P1 and DB.

Doing so could cause fire or an accident.

v

• Generally, control signal wires are not reinforced insulation. 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.

Doing so could cause an accident or electric shock.

• 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.

Operation

• Be sure to install the terminal block cover before turning the pow er on . Do not r emov e the
cover 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 restar t 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 diff erent from the set o nes. Design the machine so that
safety is ensured even in such cases.

Otherwise an accident could occur.

• The STOP key is only effective when function setting (Function code F02) has been es­tablished to enable the STOP key. Prepare an emergency stop switch separately. If you
disable the STOP key priority function and enable operation by external commands, you
cannot emergency-stop the inverter using the STOP key on the built-in keypad.

• If an alarm reset is made with the operation signal turned on, a sudden start will occur.
Ensure that the operation signal is turned off in advance.

Otherwise an accident could occur.

vi

• If you enable the "restart mode after momentary power failure" (Function code F14 = 4 or

5), then the inverter automatically rest arts running the motor w hen 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-Mini User's Manual, 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.

• Do not turn the main circuit power on or off in order to start or stop inverter operation.

Doing so could cause failure.

• Do not touch the heat sink or braking resistor because they become very hot.

Doing so could cause burns.

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

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

Injuries could occur.

Maintenance and inspection, and parts replacement

• Turn the power off and wait for at least five minutes before starting inspection. Further,
check that the LED monitor is unlit, and check the DC link bus voltage between the P (+)
and N (-) terminals to be lower than 25 VDC.

Otherwise, electric shock could occur.

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

• Take off the watch, rings and other metallic matter before starting work.

• Use insulated tools.

Otherwise, electric shock or injuries could occur.

vii

Disposal

• Handle the inverter as an industrial waste when disposing of it.
Otherwise injuries could occur.

Others

• Never attempt to modify the inverter.

Doing so could cause electric shock or injuries.

GENERAL PRECAUTIONS

Drawings in this manual may be illustrated without covers or safety shields for explanation of
detail parts. Restore the covers and shields in the original state and observe the description in
the manual before starting operation.

Conformity to the Low Voltage Directive in the EU

If installed according to the guidelines given below, inverters marked with CE are considered as
compliant with the Low Voltage Directive 2006/95/EC.

1. The ground terminal G should always be connected to the ground. Do not use only a
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)* as
the sole method of electric shock protection. Be sure to use ground wires whose size is
greater than power supply lines.

* With overcurrent protection.

2. When used with the inverter, a molded case circuit breaker (MCCB), resid­ual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) or
magnetic contactor (MC) should conform to the EN or IEC standards.

3. When you use a residual-current-operated protective device (RCD)/earth leakage circuit
breaker (ELCB) for protection from electric shock in direct or indirect contact power lines or
nodes, be sure to install type B of RCD/ELCB on the input (primary) of the inverter if the
power source is three-phase 200/400 V. For single-phase 200 V power supplies, use type
A.

When you use no RCD/ELCB, take any other protective measure that isolates the electric

equipment from other equipment on the same power supply line using double or reinforced
insulation or that isolates the power supply lines connected to the electric equipment using
an isolation transformer.

4. The inverter should be used in an environment that does not exceed Pollution Degree 2
requirements. If the environment conforms to Pollution Degree 3 or 4, install the inverter in
an enclosure of IP54 or higher.

5. Install the inverter, AC or DC reactor, input or output filter in an enclosure with minimum
degree of protection of IP2X (Top surface of enclosure shall be minimum IP4X when it can
be easily accessed), to prevent human body from touching directly to live parts of these
equipment.

6. To make an inverter with no integrated EMC filter conform to the EMC directive, it is nec­essary to connect an external EMC filter to the inv erter and install them p roperl y so that the
entire equipment including the inverter conforms to the EMC directive.

7. Do not connect any copper wire directly to grounding terminals. Use crimp terminals with tin
or equivalent plating to connect them.

8. To connect the three-phase or single-phase 200 V class series of inverters to the power
supply in Overvoltage Category III or to connect the three-phase 400 V class series of in­verters to the power supply in Overvoltage Category II or III, a supplementary insulation is
required for the control circuitry.

9. 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.

10. The power supply mains neutral ha s to be earthed for the three-phase 400 V class inverter .

11. The inverter has been tested with IEC61800-5-1 2007 5.2.3.6.3 Short-circuit Current Test
under the following conditions.

Short-circuit current in the supply: 10 kA
Maximum 240 V

Maximum 480 V

Brake motors

When driving a 400 V general-purpose motor with an inv erter
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
good 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. If constant torque is required in
the low-speed range, use a Fuji inverter motor or a motor
equipped with an externally powered ventilating fan.

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 dampe ning 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.

If the reference frequency is set to 120 Hz or more to drive a
high-speed motor, test-run the combination of the inverter
and motor beforehand to check for safe operation.

When driving an explosion-proof motor with an inv erter , 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 input (primary)
circuit. If the brake power is connected to the inverter's output
(secondary) circuit by mistake, the brake will not work.

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

such operation.

It is necessary to take special measures suitable for this
motor type.

Section 5.3 "Notes in Driving PMSM."

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

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."

Install a recommended molded case circuit breaker (MCCB)
or residual-current-operated protective device (RCD)/earth
leakage circuit breaker (ELCB) (with overcurrent protection)
in the input (primary) circuit of the inverter to protect the
wiring. Do not use the circuit breaker capacity exceeding the
recommended rated current.

If a magnetic contactor (MC) is mounted in the inverter's
secondary circuit for switching the motor to commercial
power or for any other purpose, ensure that both the inverter
and the motor are completely stopped before you turn the MC
on or off.

Do not connect a magnet contactor united with a surge killer
to the inverter's secondary circuit.

Do not turn the magnetic conta ctor (MC) in the in put (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

/ keys.

The electronic thermal function of the inv erter can prote ct 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).

Measures against
surge currents

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 output circuit. An overcurrent trip
will occur, disabling motor operation.

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

Use of a filter and shielded wires is typically recommend ed 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 phase-advancing
capacitor in the power system.

* Connect a DC reactor to the inverter.

Megger test

When checking the insulation resist ance of the inverter, use a
500 V Megger and follow the instructions contained in

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.

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

Grounding Securely ground the inverter using the grounding terminal.

motors

When exporting an inverter built in a panel or equipmen t, pack them in a previously
fumigated wooden crate. Do not fumigate them after packing since some parts
inside the inverter may be corroded by halogen compounds such as methyl bro-

listed in the standard specifications table for the inverter.
When high starting torque is required or quick accelera tion or

deceleration is required, select an inverter with a capacity
one size greater than the standard.

Select an inverter that meets the following condition:
Inverter rated current > Motor rated current

mide used in fumigation.
When packing an inverter alone for export, use a laminated veneer lumber (LVL).

Even if the humidity is within the specified requireme nts, avoid such places where the inverter will be
subjected to sudden changes in temperature that will cause condensation to form.

Precautions for temporary storage
(1) Do not leave the inverter directly on the floor.

(2) If the environment does not satisfy the specified requirements listed in Table 1.1, 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).

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

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 inst alled in the equipment or control bo ard at a constructi on 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.

2.2 Installing the Inverter

(1) Mounting base

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

Install the inverter on a base made of met al 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 panel of your system,
take extra care with ventilation in side the panel as
the temperature around the inverter tends to
increase.

2-1

1500 to 2000 m 0.95
2000 to 2500 m 0.91
2500 to 3000 m 0.88

(Note 1) When inverters are mounted
side-by-side without any gap between them,
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 panel 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.

When mounting two or more inverters
When mounting two or more inverters in the same unit or panel, basically lay them out side by side.

As long as the ambient temperature is 40°C or lower, inverters can be mounted side by side without
any clearance between them. When mounting the inverters necessarily, one above the other, be
sure to separate them with a partition plate or the like so that any heat radiating from an inverter will
not affect the one(s) above.

(3) Mounting direction

Secure the inverter to the mo unting bas e with four screws or bolt s (M4) so tha t the FRENIC-Mini logo
faces outwards. Tighten those screws or bolts perpendicular to the mounting base.

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.

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.

2.3 Wiring

Follow the procedure below. (In the following description, the inverter has already been installed.)

2.3.1 Removing and mounting the terminal block covers

(1) Loosen the screw securing the control circuit terminal block cover.
(2) Insert your finger in the cutout (near "PULL") in the bottom of the control circuit terminal block

cover, then pull the cover towards y ou.

(3) Hold both sides of the main circuit terminal block cover between thumb and forefinge r and slide

it towards you.

(4) After performing wiring, mount the main circuit terminal block cover and control circuit terminal

block cover in the reverse order of removal.

2.3.4 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 o n the nameplate .
(2) Be sure to connect the power wires to the main circuit power input terminals L1/R, L2/S and

L3/T (for three-phase voltage input) or L1/L and L2/N (for single-phase voltage input) of the
inverter. If the power wires are connected to other terminals, the inv erter w ill b e damag ed w hen
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 circui t 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 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 related 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.

• Be sure to connect the grounding wires without fail.

Otherwise, electric shock or fire could occur.

• Qualified electricians should carry out wiring.

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

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

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).

• Do not connect a braking resistor to between terminals P (+) and N (-), P1 and N (-), P (+)
and P1, DB and N (-), or P1 and DB.

Doing so could cause fire or an accident.

Figure 2.3 Wiring Procedure for Peripheral Equipment

2-7

The wiring procedure for the FRN0006C2S-2 is given below as an example. For other inverter
types, perform wiring in accordance with their individual terminal arrangement. (Refer to page 2-3.)

c Grounding terminal ( G)

Be sure to ground either of the two grounding terminals for safety and noise reduction. It is stipulated
by the Electric Facility Technical Standard that all metal frames of electrical equipment must be
grounded 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) Connect a thick grounding wire with a large surface area. Keep the wiring length as short as
possible.

d Inverter output termi nals, U, V, W and grounding terminal ( G)

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

2) Connect the grounding wire of terminals U, V, and W to the grounding terminal (

- The wiring length between the inverter and motor should not exceed 50 m. If it exceeds
50 m, it is recommended that an output circuit filter (option) be inserted.

• Do not connect a phase-advancing capacitor or surge absorber to the inverter’s output
lines (secondary circuit).

400 m or less

• If the wiring length is long, the stray capacitance between the wires will increase,
resulting in an outflow of the lea kage current. It w ill activ ate the ov ercurrent prote ction,
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 i nv erter, the wiring length should
be the total length of the wires to the motors.

2-8

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: Motor sound (Carrier frequency)).

• 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 w iring length is long, the su rge
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 (secon dary cir cuits) of

the inverter.

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

e 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.

• If both a DC reactor and a braking resistor are to be connected to the inverter, secure
both wires of the DC reactor and braking resistor together to terminal P(+). (Refer to
item

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

When wiring the inverter to the pow er supply of 500 kVA or more, be sure to co nnect an optional
DC reactor (DCR).

Otherwise, fire could occur.

f Braking resistor terminals, P(+) and DB

1) Connect terminals P and DB of a braking resistor (option) to terminals P(+) and DB on the main
circuit terminal block.

2) Arrange the inverter and braking resistor to keep the wiring length to 5 m or less and tw ist the two
wires or route them together in parallel.

Do not connect a braking resistor to any inverter of FRN0002C2S-2/-7 or below. (Even
if connected, the braking resistor will not work.)

Never insert a braking resistor between terminals P(+) and N(-), P1 and N(-), P(+) and P1, DB
and N(-), or P1 and DB.

Doing so could cause fire.

When a DC reactor is not to be connected together with the braking resistor

1) Remove the screws from terminals P(+) and P1, together with the jumper bar.

2) Connect the wire from terminal P of the braking resistor to terminal P(+) of the inverter and put the
jumper bar back into place. Then secure the wire and jumper bar with the screw.

3) Tighten the screw of terminal P1 on the jumper bar.

4) Connect the wire from terminal DB of the braking resistor to the DB of the inverter.

When connecting a DC reactor together with the braking resistor

1) Remove the screw from terminal P(+).

2) Overlap the DC reactor wire and braking resistor wire (P) and then secure them to terminal P(+) o f
the inverter with the screw.

3) Connect the wire from terminal DB of the braking resistor to terminal DB of the inverter.

4) Do not use the jumper bar.

h Main circuit power input ter minals, L1/R, L2/S, and L3/T (for three-phase voltage input)

or L1/L and L2/N (for single-phase voltage input)

1) For safety, make sure that the molded case circuit breaker (M CCB) or magnetic conta ctor (MC) i s
turned off before wiring the main circuit power input terminals.

2) Connect the main circuit power supply wires (L1/R, L2/S and L3/T or L1/L and L2/N) to the input
terminals of the inverter via an MCCB or residual-current-operated protectiv e dev ice (RCD)/earth
leakage circuit breaker (ELCB)*, and MC if necessary.

It is not necessary to align phases of the power supply wires and the input term inals of the inverte r

with each other.

* With overcurrent protection

It is recommended that a magnetic contactor be inserted w hichcan be manually activated.
This is to allow you to disconnect the inv erter from the power supply in an emergency (e.g.,
when the protective function is activate d) so as to prev ent a failure or acciden t from causing
the secondary problems.

2.3.6 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 tha t the co ntro l signal ca bles and w ires w ill 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.
Implement appropriate measure to prevent the nearby sensors and device s from malfunctio ning

due to such noise.

An accident could occur.

Table 2.8 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.

Put back the main circuit terminal block cover and then connect wires to the control cir cuit terminals.
Route these wires correctly to reduce the influence of noise.

- These low level analog 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 2.5, ground
the single end of the shield to enhance the shield effect.

- Route the wiring of the control terminals as far from the wiring of the main circuit as
possible. Otherwise electric noise may cause malfunctions.

- Fix the control circuit wires inside the inverter to keep them away from the live parts of
the main circuit (such as the terminal block of the main circuit).

- The pin assignment of the RJ-45 connector on the FRENIC-Mini series is different from
that of the RJ-45 connector on the FVR-E11S serieskeypad. Do not connect them with
each other; doing so may cause a short-circu iting or collisi on of signal line s, r esulting in
a broken inverter.

2.3.7 Setting up the jumper switches

Before changing the jumper switches, turn OFF the power and wait at least five minutes. Make
sure that the LED monitor is turned OFF. Further, make sure, using a multimeter or a similar
instrument, that the DC link bus voltage between terminals P (+) and N (-) has dropped to the
safe level (+25 VDC or below).

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

Switching the jumper switches (shown in Figure 2.11) allows you to customize the specificatio ns of
the digital I/O terminals and the RS-485 communication terminating resistor.

To access the jumper switches, remove the terminal block covers.

For details on how to remove the terminal block covers, refer to Section 2.3.1.

2.3.8 Cautions relating to harmonic component, noise, and leakage current (1) Harmonic component

Input current to an inverter includes a harmonic component that may affect other motors and
phase-advancing capacitors on the same pow er supply li ne. If the harmonic component cau ses any
problems, connect a DC reactor (option) to the inverter. In some cases, it is necessary to insert a
reactor in series with the phase-advancing 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 affect s othe r dev ices through pow er 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.

- Mount the inverter on 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.

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

(3) Leakage current

A high frequency current component generated by insulated gate bipolar transistors (IGBTs)
switching on/off inside the inverter becomes leakage current through stray capacitance of inverter
input and output wires or a motor. If any of the problems listed below occurs, take appropriate
measures against them.

Table 2.10 Leakage Current Countermeasures

Problem Measures

An earth leakage circuit
breaker* that is connected
to the input (primary) side

*With overcurrent protection

1) Decrease the carrier frequency.

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

3) Use an earth leakage circuit breaker (ELCB) with lower
sensitivity than the one currently used.

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

An external thermal relay

1) Decrease the carrier frequency.

2) Increase the settling current of the thermal relay.

4.1.1 Checking prior to powering on

Check the following prior to powering on the inverter.
(1) Check the wiring to the power input terminals (L1/R, L2/S and L3/T or L1/L and L2/N) and

inverter output terminals (U, V and W). Also check that the grounding wires are connected to the
grounding terminals correctly. See Figure 4.1.

• Do not connect power supply wires to the inverter output terminals U , V, and W. Otherw ise, 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 ele ctrodes.

Otherwise, electric shock may occur.

(2) Check the control circuit terminals and main circuit

terminals for short circuits or ground faults .

(3) Check for loose terminals, connectors and screws.
(4) Check that the motor is separated from

mechanical equipment.

(5) Make sure that all switches of devices connected

to the inverter are turned OFF. (Powering on the
inverter with any of those switches being ON may
cause an unexpected motor operation.)

(6) Check that safety measures are taken against

runaway of the equipment, e.g., a defense to
prevent people from access to the equipment.

< Tuning procedure >

1) Preparation
Check the rating plate on the motor and set the following function codes to their nominal

ratings:

• F04 and A02: Base frequency

• F05 and A03: Rated voltage at base frequency

• P02 and A16: Motor rated capacity

• P03 and A17: Motor rated current

2) Selection of tuning process
Check the situation of the machine system and select either "Tuning while the motor is

stopped (P04 or A18 = 1)" or "Tuning while the motor is running (P04 or A18 = 2)." In the
case of "Tuning while the motor is running (P04 or A18 = 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.

motor if rotated.

Even if the motor is rotated, it
is safe and no more than 50%
of the rated load would be
applied to the motor if rotated.
(Tuning with no load will
obtain the highest precision.)

Upon completion of the tuning, each motor parameter will be automatically saved into the
applicable function code.

3) Preparation of machine system
Perform appropriate preparations on the motor and its load, such as disengaging the

coupling and deactivating the safety device.
Switch to the motor 1 or motor 2, which the tuning is to be performed on.
Tuning results by P04 w ill be applied to P codes for the motor 1, and tuning results by A18

will be applied to A codes for the motor 2.

Assigning the SWM2 signal ("Switch to motor 2") to terminal [Y1] or [30A/B/C]
automatically switches the output status of SWM2 depending on the moto
selected for tuning.

4) Perform tuning
Set function code P04 or A18 to "1" or "2" and press the key . (The blinking of 1 or 2

on the LED monitor slows down.)

Enter a run command for the rotation direction selected. The factory default is " key

on the keypad for forward rotation." To switch to reverse rotation, change the data of

4-3

function code F02.

The display of 1 or 2 stays lit, and tuning starts with the motor stopped.

(Maximum tuning time: Approx. 40 s.)

If P04 or A18 = 2, the motor is accelerated to approximately 50% of the base frequency

and then tuning starts. Upon completion of measurements, the motor decelerates to a
stop.

(Estimated tuning time: Acceleration time + 20 s + Deceleration time)

Tuning continues with the motor stopped.

(Maximum tuning time: Approx. 10 s.)

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

appears upon completion of the measurements.

The run command is turned OFF. (The run command given through the keypad or the

communications link is automatically turned OFF).

The tuning completes and the next function code

p05

or

appears on the keypad.

 Tuning errors
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 tuning results or any error in the tuning process, it displays
discards the tuning data.

Listed below are possible causes that trigger tuning errors.

Other errors An undervoltage or any other alarm has occurred.

- An interphase voltage unbalance has been detected.

- Tuning has resulted in an abnormally high or low value of a parameter.
An abnormally high current has flown during tuning.
During tuning, a run command has been turned OFF, or BX ("Coast to a

stop") or other similar terminal command has been received.

- During tuning, any of the operation limiters has been activated.

- The maximum frequency or the frequency limiter (high) has limited tuning
operation.

Details

If any of these errors has occurred, remove the error cause and perform tuning again, or
consult your Fuji Electric representative.

If a filter other than the optional Fuji output filter (OFL--4A) is connected
to the inverter's output (secondary) circuit, the tuning re sult cannot be a ssured.
When replacing the inverter connected w ith such a fi lter, make a note of the old
inverter’s settings for the primary resistance %R1, leakage reactance %X,
no-load current, and rated slip frequency, and specify those values to the new
inverter’s function codes.

Chapter 5 FUNCTION CODES

5.1 Function Code Tables

Function codes enable the FRENIC-Mini 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 fol lowing tw o letters are numerals that identify each individual cod e in th e
group. The function codes are classified into eight groups: Fundamental Functions (F codes)
Extension Terminal Functions (E codes)
codes), High Performance Functions (H codes), Motor 2 Parameters (A codes), Application
Functions (J codes) and Link Functions (y codes). To determine the property of each function code,
set data to the function code.

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

Changing, validating, and saving function code data when the motor is running

 Using negative logic for programmable I/O terminals

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

T o se t the negativ e logic sy stem for an input or outp ut terminal, enter d ata of 1000s (by adding 1000
to the data for the normal logic) in the corresponding function code.

Example: "Coast to a stop" command BX assigned to any of digita l input te rminals [X1] to [X3] using
any of function codes E01 through E03.

Function code data BX

7 Turning BX ON causes the motor to coast to a stop. (Active ON)

1007 Turning BX OFF causes the motor to coast to a stop. (Active OFF)



Limitation of data displayed on the LED monitor

Only four digits can be displayed on the 4-digit LED monitor. If you enter more than 4 digits of data
valid for a function code, any digits after the 4th digit of the set data will not be displayed; however
they will be processed correctly.

The following tables list the function codes available for the FRENIC-Mini series of inverters.

In addition to the fr equency command sources desc ribed above, higher priorit
command sources including communications link and multistep frequency are
provided. For details, refer to the block diagram given in FRENIC-Mini User's
Manual (24A7-E-0023), Chapter 4, Section 4.2 "Drive Frequency Command
Generator."

• For frequency settings made by terminals [12] (voltage) and [C1] (current) and b
the built-in potentiometer, setting the gain and bias changes the relationship
between those fre quency settings and the drive frequency. Refer to function
code F18 for details.

The inverter can easily accept high-speed operation. When changing the speed setting, carefully
check the specifications of motors or equipment beforehand.

Otherwise injuries could occur.
