Long Life Components And Life Check Function; Network Connection As You Design; Free Of Environmental Worries; Simple Operation And Easy Maintenance - Mitsubishi Electric FR-A700 Manual

•
The life of a newly developed cooling fan has been extended
1
to 10 years of design life* . The life of the cooling fan is further
extended with ON/OFF control of the cooling fan.
•
Longevity of capacitor was achieved with the adoption of a
design life of 10 years* 1 * 2 .
(A capacitor with specification of 5000 hours at 105 C ambient
temperature is adapted.)
*1 Ambient temperature : annual average 40 C (free from corrosive gas, flammable
gas, oil mist, dust and dirt).
Since the design life is a calculated value, it is not a guaranteed value.
*2 Output current: equivalent to rating current of the Mitsubishi standard motor (4 poles).
•
Life indication of life components
Cooling fan 10 years 2 to 3 years
Main circuit smoothing capacitor 10 years 5 years
Printed board smoothing capacitor 10 years 5 years
*3 Excerpts from "Periodic check of the transistorized inverter" of JEMA (Japan Electrical
Manufacturer's Association).
The inverter can be connected to the Mitsubishi PLC (Q, QnA, A
series, etc.) through the CC-Link. It is compatible with the CC-
Link Ver.1.1 and Ver.2.0. The inverter operation, monitoring and
parameter setting change can be done from the PLC.

The inverter can be connected to Mitsubishi motion controller
through the SSCNETIII. The SSCNETIII employs a high-speed
synchronous serial communication system and is appropriate for
the synchronous operation.

•
Degrees of deterioration of main circuit capacitor, control circuit
capacitor or inrush current limit circuit can be monitored.
•
Since a parts life alarm can be output* 4 by self-diagnosis,
troubles can be avoided.
*4 Any one of main circuit capacitor, control circuit capacitor, inrush current limit
circuit and cooling fan reaches the output level, an alarm is output.
For the main circuit capacitor, the capacitor capacity needs to be measured during
a stop by setting parameter.
•
The RS-485 terminals are equipped as standard in addition to
the PU connector.
You can make RS-485 communication with the operation panel
or parameter unit connected to the PU connector.
•
Since the inverter can be connected to the network with terminals,
multi-drop connection is also easily done.
•
Modbus-RTU (Binary) protocol has been added for
communications in addition to the conventional Mitsubishi
inverter protocol (computer link).
•
As a USB connector (USB1.1B connector) is standard equipped,
communication with a personnel computer can be made with a
USB cable only.
•
Using the RS-485 terminal or USB connector, you can make
communication by the FR-Configurator (setup S/W).
The inverter can be connected with networks such as Device-
NET™, PROFIBUS-DP, L W , EtherNet (available soon)
ON ORKS
and CANopen (available soon) when communication options
are used.

•
Reduction of noise generated from the inverter was achieved
with adoption of a new technology (low-noise of
switching power, low noise of inverter element).
•
Because of the newly developed built-in noise
filter (EMC filter), the inverter itself can comply
3
with the EMC Directive (2nd Environment* ).
1
(To make the EMC filter of the inverter valid* ,
set ON/OFF connector* 2 to ON.)
*1 Leakage current will increase when the EMC filter is selected.
*2 Since the leakage current when using the EMC filter for the 200V class 0.4K and
0.75K is small, the filter is always valid (setting connector is not provided).
*3 Refer to the EMC installation manual for compliance conditions.

•
Parameter management (parameter setting, file storage, printing) is easy.
•
Maintenance and setup of the inverter can be done from a
personal computer connected with USB.
•
Mechanical resonance is easily avoided with machine analyzer function.
•
Parameter setting after
replacement of the FR-
A500 series can be made
with a parameter automatic
conversion function.
•
Possible to copy parameters with operation panel.
Parameter setting values are stored in the operation panel
and optional parameter unit (FR-PU07).
•
Operation is easy with the setting dial.
•
Operation panel is detachable and can
be installed on the enclosure surface.
(cable connector option is required)
•
PU/EXT (operation mode) can be
switched with a single touch.
•
A dial/key operation lock function
prevents operational errors.
•
A compact AC reactor (FR-HAL) and a DC reactor (FR-HEL),
which limit harmonics current flowing into the power supply
and improve the power factor, are available as options. (For
the 75K or more, a DC reactor is supplied as standard.)
•
A high power factor converter (FR-HC, MT-HC) for effective
suppressions of power-supply harmonics (conversion
coefficient: K5=0) can be connected.
Because of the built-in inrush current limit circuit, the current at
power on can be restricted.
•
An operation panel can be removed and a parameter unit
can be connected.
•
Setting such as direct input method with a numeric keypad,
operation status indication, and help function are usable.
Eight languages can be displayed.
•
Parameter setting values of a maximum
of three inverters can be stored.
•
Since a battery pack type (available soon)
is connectable, parameter setting and
parameter copy can be performed without
powering on the inverter.
Cooling fans are provided on top of the
inverter.
Cooling fans can be replaced without
disconnecting main circuit wires.
A removable terminal block was adapted.
(The terminal block of the FR-A700 series
is compatible with that of the FR-A500
series. Note that some functions of the
FR-A700 series are restricted when using
the terminal block of the FR-A500 series.
Note that the wiring cover is not compatible.)
Since a wiring cover can be mounted after wiring, wiring work
is easily done.
