Quoted from “Low Power AC Drive Worldwide Outlook” (2001) published by ARC(USA

)

Optimum performance for traversing conveyors

High starting torque, at 150% or more

Equipped with Fuji,s original simplified torque-vector control
system and the automatic torque boost function, the inverter
provides consistent powerful operation (when automatic torque
boost is ON, slip compensation control is ON, and when
running at 5Hz or more).

Braking resistor connectable to the inverter

Owing to a built-in braking transistor (1/2HP or larger), an optional
braking resistor can be connected to increase the regenerative
braking capacity for conveyance and transportation machinery that
require large braking power. For inverters of 2HP or larger, it is
possible to select the model that incorporates a braking resistor.

The ideal functions to serve a multiplicity of needs for small-capacity inverters

Compatible with a wide range of
frequency settings

The optimum frequency setting method can be selected to
match your machine or equipment. Setting can be done by
keypad panel ( keys, potentiometer), analog input (4 to
20mA, 0 to +10V, 0 to 5V, 1 to 5V), multistep speed settings (8
steps) etc.

A transistor output is provided.

This enables an overload early warning, lifetime forecast or
other information signals to be output during operation.

Compact

Side-by-side mounting is possible.

Multiple inverter units can be mounted side-by-side inside a
panel. This features helps to minimize the space used for
installation. (Ambient temperature: 40°C (104°F) or less)

The output frequency can be set to a
maximum of 400Hz.

The inverter can be used for equipment that requires a high
motor speed such as centrifugal separator. In this case, check
the operation in combination with the motor.

Two points can be set for a non-linear
V/f pattern.

One point for the non-linear V/f pattern, which can be set as
desired, has been added (making a total of 2 points), and so
the V/f pattern can be adjusted to match the application.

Size interchangeability with Fuji,s
FVR-C11S series is provided.

can also be checked.

It is possible to output lifetime forecast
signal to the transistor output.

This signal is output when the capacitors in the DC bus circuit,
the electrolytic capacitors on the PCB or the cooling fans are
nearing the end of their service life.

Input/output phase loss protective function

It is possible to detect output phase loss at all times during
starting and operation.

Sink/Source can be switched.

The input/output mode (Sink/Source) of the digital input terminals
can be switched by means of an internal jumper switch.

Run/Stop operation and frequency setting on the keypad

[Wiring method]

1. Connect the inverter main power circuit only.
[Operation method]

1. Run/Stop ... Press or key on the keypad.

2.

Setting frequency ... Turn the potentiometer on the keypad.

Note 1: To protect the circuit from overcurrent, install a

recommended molded-case circuit breaker (MCCB) or a
ground-fault circuit interrupter (GFCI) (equipped with
overcurrent protection function) on the inverter's input
side (primary circuit). Ensure that the circuit breaker
capacity does not exceed the recommended value.

Note 2: Besides the above MCCB or GFCI, install a

recommended magnetic contactor (MC) to the inverter if
it is necessary to disconnect the inverter from the power
supply.
When installing an MC or a solenoid coil near the
inverter, connect a surge suppressor in parallel with it.

[Operation method]
(1) Run/Stop ... Short-circuit the terminals FWD and CM to run, and

open the circuit to stop.

(2) Setting frequency ... Voltage input (0 to +10V DC); Current input (+4

to 20mA DC)

Note 1: Before connecting a DC REACTOR (option), remove the jumper

bar between the terminals [P1] and [P+]. For the single-phase
100V series, the reactor connection terminals are different. For
details, refer to the Instruction Manual.

Note 2: To protect the circuit from overcurrent, install a recommended

molded-case circuit breaker (MCCB) or
interrupter (GFCI)

function) on the inverter's input side (primary circuit). Ensure that
the circuit breaker capacity does not exceed the recommended
value.

Note 3: Besides the above MCCB or GFCI, install a recommended

magnetic contactor (MC) to the inverter if it is necessary to
disconnect the inverter from the power supply.
When installing an MC or a solenoid coil near the inverter,
connect a surge suppressor in parallel with it.

Note 4: Frequency can be set by connecting a frequency setting device

(external potentiometer) between the terminals 13, 12, and 11
instead of inputting voltage signal (0 to +10V DC or 0 to +5V DC)
between the terminals 12 and 11.

Note 5: Use shielded or twisted cables as the control signal wires, and

connect the shielded cables to the ground. To prevent
malfunction due to noise, keep the control signal wires away
from the main circuit wires as far as possible (10cm or more
recommended), and avoid storing them in the same wire duct.
When they need to cross with each other, lay them at right
angles.

Note 6: (THR) function can be used by assigning code " " (Trip

command) to any of the terminals X1 to X3, FWD or REV
(function code; to , , or ).

Note) A in the alarm output (30A,B,C) column indicates that there are cases where an alarm is not output in accordance with the function code.

Stops the inverter output to protect the inverter from an overcurrent resulting from overload.

•

Stops the inverter output to protect the inverter from an overcurrent due to a short-circuit in the output circuit.

•

Stops the inverter output to protect the inverter from an overcurrent due to a ground fault

in the output circuit. This protection is effective only when the inverter starts. If you turn

on the inverter without removing the ground fault, this protection may not work.

The inverter stops the inverter output upon detecting an overvoltage condition
(400V DC for three-phase 230 V, single-phase 230 V, and single-phase 115 V
class series; 800 V DC for three-phase 460 V class series) in the DC link bus.
This protection is not assured if excess AC line voltage is applied inadvertently.

Stops the inverter output when the DC link bus voltage drops below the undervoltage level (200 V
DC for three-phase 230 V, single-phase 230 V, and single-phase 115 V class series; 400 V DC for
three-phase 460 V class series).
However, if data "4 or 5" is selected for F14, no alarm is output even if the DC link bus voltage drops.

Detects input phase loss, stopping the inverter output. This function prevents the inverter from undergoing heavy stress

that may be caused by input phase loss or interphase voltage unbalance and may damage the inverter.

If connected load is light or a DC reactor is connected to the inverter, this funtion will not detect input phase loss if any.

In single-phase series of inverters, this function is disabled by factory default.

Detects breaks in inverter output wiring at the start of running and during running, stopping the inverter output.

Stops the inverter when it detects excess heat sink temperature in case of cooling fan failure or overload.

•

•

When the built-in or external braking resistor overheats, the inverter stops running.

It is necessary to set the function code corresponding to the braking resistor used (built-in or external).

*

Calculates the IGBT internal temperature from the output current and internal temperature detection, stopping the inverter.

The inverter stops running the motor to protect the motor in accordance with the electronic thermal

function setting.

• Protection of a standard motor over the entire frequency range.

• Protects the inverter motor over the entire frequency range.

* The operation level and thermal time constant can be set.

• A PTC thermistor input stops the inverter to protect the motor.

A PTC thermistor is connected between terminals C1 and 11, and a 1kΩ external resistor is

connected between terminals 13 and C1.

Outputs a preliminary alarm at a preset level before the inverter is stopped by the electronic thermal

function for the purpose of protecting the motor.

Operates when the instantaneous overcurrent hits the set limit.

Instantaneous overcurrent limit: Operates if the inverter output current exceeds the instantaneous overcurrent

limit to prevent the inverter from tripping (during acceleration or negative constant speed operation).

• Stops the inverter with an alarm through the digital input signal (THR).

• The inverter outputs a relay contact signal when the inverter issues an alarm and stopped.

<Alarm reset>

The alarm stop state is reset by pressing the key or by the digital input signal (RST).

<Saving the alarm history and detailed data>

The information on the previous 4 alarms can be saved and displayed.

The inverter checks memory data after power-on and when the data is written. If a memory error is detected, the inverter stops.

The inverter stops by detecting a communication error between the inverter and the remote keypad

(option) during operation from the remote keypad.

If the inverter detects a CPU error caused by noise or some other factor, the inverter stops.

Pressing key on the keypad forces the inverter to decelerate and stop the motor even

priority

Start check

function

On detecting an RS-485 communication error, the inverter displays the error code.

If the data could not be saved during activation of the undervoltage protection function, the inverter

displays the error code.

if the inverter is running by any run commands given via the terminals or communications

(link operation). After the motor stops, the inverter issues alarm " ."

Inverters prohibit any run operations and displays " " on the LED of keypad if

any run command is given when:

• Powering up

• Releasing an alarm (

Suppresses surges or noise invading from an external source, preventing malfunction from
magnetic contactors, control relays and timers, etc.

Suppresses induced lightning surges from power source, thus protecting all equipment
connected to the power source.

Absorbs surges or noise invading from an external source, preventing malfunction of electronic
equipment used in the switchboard.

Frequency setting potentiometer (mounted externally)

Displays the frequency in accordance with signals output from the inverter.

This is used in cases where a single-phase 115V power supply is used to feed a three-phase
230V inverter. (It can be applied to the inverter of 1HP or less.)

This is a dedicated filter which complies with the European EMC (Emission) Directive.

Used for power factor improvement and power supply coordination. However, it is
recommended that a DC REACTOR with a higher efficiency and which is more compact and
lightweight be used. Use a DC REACTOR (DCR) as a countermeasure for harmonics. If it is
necessary to supply a stabilized power supply, such as a DC bus system and running from that
(PN connection operation), please use such a reactor.

Reduces radio frequency noise. If the wiring between motor and inverter is shorter than 66ft (20m),
use the ferrite ring in the power supply side. If longer than 66ft (20m), use it in the output side.

Reduces noise.
For frequencies in the AM radio frequency band of 1MHz or less, a noise reduction effect can be
obtained. Absolutely never connect this device to the inverter’s output side.

[Use the DCR to normalize the power supply in the
following cases.]

1. The power transformer capacity is 500kVA or over and
exceeds the inverter rated capacity by 10 times.

2.

The inverter and a thyristor converter are connected
with the same transformer.

*Check if the thyristor converter uses a

commutation reactor. If not, AC reactor must
be connected to the power supply side.

3.

Overvoltage trip occurs due to open/close of the
phase-advancing capacitor for the power supply lines.

4.

The voltage unbalance exceeds 2%.

Voltage unbalance (%) = x 67

[For improving input power-factor, reducing harmonics]

• Used to reduce input harmonic current (correcting power-factor)

Used to increase the braking capability when the motor needs to start and stop frequently or
when the moment of inertia is large.

This filter is connected to the output circuit of inverters, and has the following functions:

1.

Suppressing fluctuation of motor terminal voltage

Protects the motor insulation from being damaged by surge voltage.

2.

Suppressing leakage current from output side wiring

Reduces the leakage current caused when several motors are operated in parallel or
connected with long wiring.

3.

Suppressing radiation noise or inductive noise from output side wiring

Effective noise suppression device for long wiring applications such as plant

* There are two kinds of filters for 460V series. Choose a desired one according to the purpose of use.

This makes communication to a PLC or personal computer system easy.

Used to connect the RS-485 communications card with the remote keypad, USB-RS-485
converter, etc.

Used when performing inverter remote operations with the remote keypad.Remote keypad

Allows copying data to several inverters with easy connection to the inverter body.

Used for the connector replacement of the copy adaptor.

Inverter support loader software, Windows based, that makes setting of function codes easy.

Used to connect the RS-485 communications card with a USB port of your personal computer.

NEMA1 kit protects the inverter body with the structure that conforms to the NEMA1 standard
(approved as UL TYPE1).

Permit change of protective structure, replacement of Fuji's previous inverter model and
installation on the DIN rails, etc.

Prevents the motor insulation from being damaged by the surge current of the inverter.

Application to standard motors

• Driving a 460V standard motor

When driving a 460V standard motor by an inverter
with long cable lengths, damage may occur in the
insulation of motor. Use the output circuit filter
(OFL) if necessary after confirmation with the motor
manufacturer.The use of Fuji Electric Motor does
not require the output circuit filter because of its
reinforced insulation.

•

Torque characteristics and temperature rise

When the inverter is used to operate a standard
motor, the temperature rises higher than during
operation from a commercial power supply. The
cooling effect decreases in the low-speed range,
reducing the allowable output torque. (If a constant
torque is required in the low-speed range, use a
Fuji inverter motor or a motor equipped with a
separately ventilating fan.)

• Vibration

Use of an inverter does not increase vibration of a
standard motor, but when the motor is mounted to a
machine, resonance may be caused by the natural
frequencies including the natural frequency of the
machine system.
* We recommend that you use a rubber coupling or
anti-vibration rubber.
* We also recommend that you use the inverter
jump frequency control function to avoid resonance
point in the motor operation.
Note that operation of a 2-pole motor at 60Hz or
over may cause abnormal vibration.

• Noise

When an inverter drives a standard motor, the
motor noise level increases compared with driven
by commercial power. To reduce noise, set the
inverter carrier frequency at a high level. High­speed operation at 60Hz or over can result in more
noise.

Application to special motors

• Explosion-proof motors

When driving an explosion-proof motor with an
inverter, use a combination of a motor and an
inverter that has been approved in advance. Such
approved products are available in our special
product series. Contact Fuji for details.

• Submersible motors and pumps

These motors have a larger rated current than
standard motors. Select the inverter capacity so
that these motors can run within the inverter rated
current. These motors differ from standard motors
in thermal characteristics.
Set a small value according to the thermal time
constant of motor for setting electronic thermal relay
function.

• Brake motors

For the motors with parallel-connected brakes,
connect the brake power cable to the inverter's
input side (primary circuit). If the brake power is
connected to the output side (secondary circuit), the
power may not be supplied to the brake, resulting in
non-actuation of the brake. Do not use inverters for
driving motors equipped with series-connected
brakes.

• Geared motors

When the power transmission mechanism uses an

NOTES

oil-lubricated gearbox or speed changer/reducer,
continuous motor operation at low speed may
cause poor lubrication.

• Synchronous motors

Synchronous motors cannot be driven by FRENIC­Mini inverter.

• Single-phase motors

Single-phase motors are not suitable for inverter­driven variable speed operation. Use three-phase
motors.
* Even if a single-phase power supply is available,
use a three-phase motor, because the inverter
provides three-phase output.

Combination with peripheral device

• Installation location

Use the inverter in an ambient temperature range
between -10 to 50°C (14 to 122°F).
The inverter and braking resistor surfaces become
hot under certain operating conditions. Install an
inverter on non-flammable material.

• Installing a circuit breaker

To protect the circuit from overcurrent, install a
recommended molded-case circuit breaker (MCCB)
or a ground-fault circuit interrupter (GFCI)
(equipped with overcurrent protection function) on
the inverter's input side (primary circuit). Ensure
that the circuit breaker capacity does not exceed
the recommended value.

•

Magnetic contactor on the output side (secondary circuit)

When a magnetic contactor is installed on the
inverter's output side (secondary circuit) for such a
purpose as switching the power to the commercial
power supply, ensure that both inverter and motor
are stopped before switching. Remove the surge
suppressor integrated with the magnetic contactor.

•

Magnetic contactor on the input side (primary circuit)

Avoid frequent open/close (more than once an
hour) of the circuit using the magnetic contactor on
the input side (primary circuit). It may cause
malfunction of the inverter. If frequent starts and
stops are required, use signals to the control
terminals FWD or REV.

• Protecting the motor

When you drive a motor with an inverter, the motor
can be protected with an electronic thermal relay
function of the inverter. In addition to the operation
level, set the motor type (standard motor, inverter
motor). For high-speed motors or water-cooled
motors, set a small value in the thermal time
constant to protect the motor in combination with
the “cooling system OFF” signal. When driving
several motors with an inverter, connect a thermal
relay to each motor and turn on the inverter’s
electronic thermal relay function. If you connect the
motor thermal relay to the motor with a long cable,
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).

• Power-factor correcting capacitor

Do not mount the power-factor correcting capacitor
in the inverter primary circuit. (Use the DC reactor
to improve the inverter power factor.) Do not use
the power-factor correcting capacitor in the inverter
secondary circuit. Overcurrent trip will occur,

disabling motor operation.

• Reducing noise

Use of filter and shielded wires are typical measures
against noise that meets EMC Directives. For
details, refer to the operation procedure manual.

• Measures against surge current

If OV 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 insulation resistance of the inverter,
use a 500V megger and follow the instructions
described in the instruction manual.

Wiring

• Control circuit wiring length

When using remote control, limit the wiring length
between the inverter and operator box to 65.6ft
(20m) or less and use twisted shielded cable.

• Wiring length between inverter and motor

If long wiring is used between the inverter and the
motor, the inverter will overheat or trip because of
overcurrent (under the influence of high-frequency
current flowing into the stray capacitance) in the
wires connected to the phases. Ensure that the
wiring is shorter than 164ft (50m) for models 5HP or
smaller, shorter than 328ft (100m) for 7.5HP or
larger. If these lengths must be exceeded, lower the
carrier frequency or mount an output circuit filter
(OFL).
When wiring is longer than 164ft (50m), and
Dynamic torque-vector control is selected, execute
off-line tuning.

• Wiring size

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

• Grounding

Securely ground the inverter using the grounding
terminal.

Selecting inverter capacity

• Driving standard motor

Select an inverter from the capacity range of
nominal applied motors shown in the inverter
standard specifications table. When large starting
torque is required or acceleration or deceleration is
required in a short time, select an inverter with a
capacity one size greater than the standard.

• Driving special motor

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

Transportation, storage

When transporting or storing inverters, select the
procedures and places that meet the environmental
conditions given in the inverter specifications.
Ensure that the above environmental conditions are
met also when transporting an inverter mounted to
a machine.
