100% output torque refers to
the rated torque of the motor
driven at 60 Hz.

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).

Trip-free operation

The remarkably improved current limiting function (stall
prevention) allows trip-free operation even for an impact load.

Stable operation even for a step load

The slip compensation function permits stable operation even
when the motor load fluctuates (step load).

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.

Reduced motor instability at low speed

Fuji,s unique control method improves voltage control
performance and reduces motor instability at low speed to about a
half or less (at 1Hz) compared with that of conventional inverters.

Automatic energy-saving provided
as a standard function

By controlling the motor loss to a minimum, FRENIC-Mini
further saves electric power when applied to fans or pumps.

Cooling fan ON/OFF control function

The inverter,s cooling fan can be turned off while the fan or
pump is stopped for noise reduction and energy savings.

PID control function

Permits motor operation while controlling temperature,
pressure, or flow rate without using an external device such as
temperature controller.

Safety Precautions

1. The contents of this catalog are provided to help you select the product model that is best for you. Before actual use, be sure
to read the Instruction Manual/User,s Manual thoroughly to assure correct operation.

2. This product is not designed and manufactured for use in machines or systems which human life is dependent upon. If you
are studying use of the products in this brochure for special purposes such as for control of nuclear power stations, in sea, air
or space craft, in medical or land transportation equipment, or any related systems, please contact the business office of Fuji
Electric. If these products are to be used in any equipment in which there is a risk to human life or the possibility of a major
loss in the event of failure, be sure to install the appropriate safety equipment.

The above graph shows an example of torque characteristics obtained when FRENIC-Mini is
combined one-to-one with Fuji,s standard three-phase motor (8-type series: 4 poles).

RS-485

communications card

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.

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.

Side-by-side mounting is possible.

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.

RS485 communications card (option)
can be installed internally.

This card can be installed inside the inverter,s body without
changing the dimensions. RS-485 communications are
available as option.

A model with built-in braking resistor is
available on order.

For inverters of 2HP or larger, a built-in braking resistor type
can be selected.
Since installation and wiring of a separate braking resistor is
not required, the total mounting space is reduced.

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

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)

Simple operation and wiring

Frequency setting potentiometer is
standard equipment.

The frequency can be adjusted easily by hand.

A menu mode is included in the keypad.

A long-life cooling fan is included.

Cumulative running time is recorded and displayed.

The inverter records and displays the cumulative running time
(lifetime) of the inverter itself, PCB, and cooling fan.

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.

The motor can be protected by a PTC thermistor.

In addition to the protection by an electronic thermal relay, the

All types of data can be displayed on
the keypad.

The output frequency, set frequency, load shaft speed, output
current, output voltage, alarm history, input power etc. can be
displayed.

The lifetime of the DC bus capacitor can
be estimated.

The capacitor,s condition compared with its initial state can be
confirmed.

All models are equipped with an inrush
current suppression circuit.

An inrush current suppression circuit is provided as standard
in all models, so the cost of peripheral devices such as input
magnetic contactors can be reduced.

A DC reactor (DCR) connection terminal
is provided as standard.

A terminal for connection of a DCR, necessary for suppressing
harmonics, is provided in all models.

The alarm history for the 4 latest
alarms is recorded.

Detailed information from back as far as the 4 latest alarms
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.

Use of a long-life cooling fan (design life: 7 years with an
ambient temperature: 40°C (104°F) reduces maintenance work.

The menu items include the function menu for checking or
changing function codes, operation monitor , I/O check ,
maintenance info. and alarm info. See the FRENIC-Mini
User,s Manual for details.

function, so function codes can be set easily in duplicate units.

Mounting on DIN rail

Using the rail mounting base (option), the inverter can be
easily mounted on a DIN rail (35mm wide).

*1) Standard 4-pole motor
*2) Rated capacity is calculated by regarding the output rated voltage as 220V for three-phase 230V
series, and as 440V for three-phase 460V series.
*3) Output voltage cannot exceed the power supply voltage.
*4) Use the inverter at the current given in ( ) or below when the carrier frequency setting is higher
than 4kHz ( : to ) or the ambient temperature is 40°C (104°F) or higher.
*5) Calculated under the standard overload conditions by JEMA committee (about 85% of overload

by the standard applicable motor.)

*6) Calculated under Fuji-specified conditions.

*7) Obtained when a DC reactor (DCR) is used.
*8) Average braking torque obtained with AVR control OFF (Varies with the efficiency of the motor.)
*9) Average braking torque obtained by use of external braking resistor (optional)

*10) Voltage unbalance [%] =

If this value is 2 to 3%, use AC reactor (option).

*11) NEMA1 kit (option) is required for the enclosure conforming to the UL standard TYPE1 (NEMA1).

Use the inverter in the ambient temperature range from -10 to +40°C (14 to 104°F).
