The FRENIC-Mini features a full range of functions, compact body, simple operation, wide model
variations, and global compatibility. It will meet your needs for higher performance in machines and
equipment such as conveyors, fans, pumps, centrifugal separators and food processing machines,
as well as the needs for system integration, energy saving, labor saving, and total cost reduction.

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.

Trip-free operation

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

The highly used functions for fans and pumps

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.

Energy saving rate varies with the motor characteristics.

PID control function

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

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.

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.

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.

Maintenance

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.

A menu mode is included in the keypad.

The menu items include the function menu for checking or
changing function codes, operation monitor , I/O check ,

The lifetime of the DC bus capacitor can
be estimated.

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

A long-life cooling fan is included.

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

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.

Interface for peripheral devices and comprehensive protective functions

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.

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
motor is protected by a PTC thermistor input.

Flexible through optionals

Function code copy function

The optional remote keypad panel includes a built-in copy
function, so function codes can be set easily in duplicate units.

Inverter support loader software is
available.

The inverter support loader program (Windows based), which
simplifies setting of function codes, is provided.
The optional RS-485 communications card, remote operation
extension cable and USB-RS-485 converter are necessary.

Mounting on DIN rail

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

Replacement of older models
with new ones is simple.

The latest models can be mounted without drilling additional
holes by use of the mouting adapter (option).

Remote operation is possible.

Remote operation can be done easily using the optional
RS-485 communications card, remote keypad and remote
operation extension cable.

*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.
