Example of torque characteristic under real sensorless vector control
When the motor SF-JR 4P is used (at 220V input)
High accuracy/fast response speed operation by the vector control
can be performed with a general-purpose motor without encoder.
•Maximum of
200% high torque can be generated at an ultra low
speed of 0.3Hz (0.4K to 3.7K).
•Torque control operation can be performed also.*(Torque control
range 1:20, absolute torque accuracy +
_20%, repeated torque
accuracy +
_10%)
•Response level has been improved.
Speed control range 1:200 (0.3Hz to 60Hz driving only)
Speed response 120rad/s
*Since torque control can not be performed in the low speed regeneration region and
at a low speed with light load, use the vector control with encoder.
*1 A plug-in option for encoder feed back control (FR-A7AP) is necessary.
*2 Only a pulse train+code system is employed for pulse command system when
performing position control with an inverter and the FR-A7AP.
The maximum pulse input is 100kpps.
Example of torque limit characteristic
When the motor SF-JR 4P 3.7kW is used
Example of input command signal response characteristic
1. Torque limit function limits the maximum
motor torque during speed control
2. Improvement of input command signal response
The delay to the input command has been minimized. The response
time has been reduced to half as compared to the conventional model
(FR-A500). It is suitable for cycle-operation applications.
Torque limit function is effective to prevent machine from damage (prevention against
damage of grinding machine tools, etc.) against the sudden disturbance torque.
3. Quick response to the sudden load fluctuation
Torque response level to the sudden load fluctuation has been greatly improved as compared to the conventional model (FR-A500).
The motor speed variation is minimized to maintain a constant speed. It is suitable for a sawmill machine, etc.
The actual motor speed
decelerates instantly at the
moment when the load
torque increases and then
it immediately returns to
the set speed.
The actual motor speed
increases instantly at the

1. Easy gain tuning
Since the load inertia of the motor is automatically estimated online
to calculate the optimum speed control gain and position loop gain,
gain adjustment is easily done. By repeating acceleration and
deceleration, load inertia is automatically estimated.
Use of vector control dedicated motor realizes 100% of the
continuous operation torque even at a low speed. It is suitable
for winder and unwinder applications. Motors with speed ratio
of 1000/2000r/min, 1000/3000r/min and 500/2000r/min
specifications are available and they can support applications
whose winding diameter greatly changes. Decreasing the
rated speed will increase the rated torque, so you can select a
motor with a smaller capacity. (The inverter one rank higher
than the motor in capacity needs to be selected depending on
the motor capacity.)

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.
•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, LONWORKS, EtherNet (available soon)
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
with the EMC Directive (2nd Environment*3).
(To make the EMC filter of the inverter valid*1,
set ON/OFF connector*2to ON.)
•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.
•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.
•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.
Cooling fans are provided on top of the
inverter.
Cooling fans can be replaced without
disconnecting main circuit wires.
Since a wiring cover can be mounted after wiring, wiring work
is easily done.
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.)
•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.
•
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.

For the 75K or more, a
DC reactor is supplied.
Always install the reactor.
*The inverter may trip and the motor may coast depending on the load condition.
Tuning accuracy equivalent to that of the conventional tuning of
“with rotation mode” is realized with the auto tuning without
motor running. Even for the machine which disallows a motor to
run during tuning, the motor performance can be maximized.
The sophisticated auto tuning function which measures circuit constants
of the motor allows sensorless vector control with any kind of motor.
•The motor can be decelerated to a stop when a power failure
or undervoltage occurred to prevent the motor from coasting.
For fail-safe of machine tool, etc., it is effective to stop the
motor when a power failure has occurred.
•Since the original operation continuation at instantaneous
power failure function has been newly adopted, the motor
continues running without coasting even if an instantaneous
power failure occurs during operation.
For operations of such as a pressing machine, in which an
instantaneous regeneration occurs, overvoltage trip can be
made less likely to occur by increasing frequency during
regeneration.
Speed command by pulse train signal (single pulse) from the
controller etc. can be directly input to the inverter.
Since pulse can be output from the inverter at the same time,
synchronous speed operation of inverters can be performed.
(maximum pulse input 100kpps, output 50kpps)
•For the analog input terminal (two points), you can switch
between voltage (0 to 5V, 0 to 10V) and current (0 to 20mA).
•You can display the ON/OFF status of the I/O terminals on the
operation panel.
•Two points relay output is available.
Compliance with both 240V power supply (55K or less) and
480V power supply as standard.
In addition to the 0.4K to 7.5K, a brake transistor is built-in to the
11K, 15K, 18.5K and 22K. A brake resistor (option) can be also
connected to the 11K to 22K.

Install a noise filter to reduce
the electromagnetic noise
generated from the inverter.
Effective in the range from
about 1MHz to 10MHz. A wire
should be wound four turns at
a maximum.
Three-phase AC power supply
Use within the permissible power
supply specifications of the inverter.
Moulded case circuit breaker (MCCB)
or earth leakage breaker (ELB), fuse
The breaker must be selected
carefully since an in-rush current
flows in the inverter at power on.
Magnetic contactor (MC)
Install the magnetic contactor to
ensure safety. Do not use this
magnetic contactor to start and stop
the inverter. Doing so will cause the
inverter life to be shorten.
Reactor (FR-HAL, FR-HEL option)
Reactors (option) must be used when
power harmonics measures are
taken, the power factor is to be
improved or the inverter is installed
near a large power supply system
(1000kVA or more). The inverter may
be damaged if you do not use
reactors. Select the reactor according
to the model. Remove the jumpers
across terminals P-P1 to connect the
DC reactor to the 55K or less.
Do not install a power factor correction
capacitor, surge suppressor or radio noise
filter on the output side of the inverter. When
installing a moulded case circuit breaker on
the output side of the inverter, contact each
manufacturer for selection of the moulded
case circuit breaker.
To prevent an electric shock, always earth
(ground) the motor and inverter. For
reduction of induction noise from the power
line of the inverter, it is recommended to wire
the earth (ground) cable by returning it to the
earth (ground) terminal of the inverter.
