As compared with the combination of the conventional system
(inverter+power regeneration converter+AC reactor), total costreduction can be achieved. Since regeneration energy is returned
to the power supply, less heat is generated as compared to the
resistor driving method, and energy saving effect can be expected.

Description
Connect to the commercial power supply.
Connect a three-phase squirrel-cage motor.
Connected to the AC power supply terminals R/L1 and S/L2. To retain the fault display and
fault output, remove the jumpers from terminals R/L1-R1/L11 and S/L2-S1/L21 and apply
external power to these terminals.
Do not turn off the power supply for control circuit (R1/L11, S1/L21) with the main circuit
power (R/L1, S/L2, T/L3) on. Doing so may damage the inverter. The circuit should be
configured so that the main circuit power (R/L1, S/L2, T/L3) is also turned off when the
power supply for control circuit (R1/L11, S1/L21) is off.

Measures against leakage currents
Take the following measures to prevent a peripheral device malfunction or electric shock accident
from occurring due to a leakage current.
1. Ground (earth) the EMC filter before connecting the power supply.
In that case, make certain that grounding (earthing) is securely performed via the grounding
(earthing) part of the panel.
2. Select the earth leakage circuit breaker or earth leakage relay in consideration of the EMC filter's
leakage current *.
When the leakage current of the EMC filter is too large to use the earth leakage circuit breaker or
earth leakage relay, securely perform grounding (earthing) as described in 1.
* The leakage current indicated is equivalent to one-phase of three-phase three wire
connection power supply.
For a three-phase, three-wire, delta-connection power supply, the value is about three times
greater than the indicated.
Some noise filters available on the market have small leakage current, although they are not
European Directive compliant.

Although this product is manufactured under strict quality control,
safety devices should be installed when a serious accident or loss
is expected by a failure of this product.
The load used should be a three-phase induction motor only.
Operation
Setting
The inverter can be operated as fast as a maximum of 400Hz by
parameter setting. Therefore, incorrect setting can cause a danger.
Set the upper limit using the maximum frequency limit setting
function.
A magnetic contactor (MC) provided on the input side should not be

operation voltage or operation time can cause motor overheat
(electronic thermal relay trip).
At the inverter alarm occurrence, the protective function activates to
stop output. However, at this time, the motor cannot be brought to
a sudden stop. Hence, provide a mechanical stopping/holding
mechanism for the machine/equipment which requires an
emergency stop.
It will take time for the capacitor to discharge after shutoff of the
inverter power supply. When accessing the inverter for inspection,
wait for at least 10 minutes after the power supply has been
switched off, and check to make sure that there are no residual
voltage using a tester or the like.
Wiring
Application of power to the output terminals (U, V, W) of the inverter
will damage the inverter. Therefore, fully check the wiring and
sequence to ensure that wiring is correct, etc. before powering on.
Do not use P/+ and N/-. Do not short the frequency setting power
supply terminal 10 and common terminal 5 or the terminal PC and
terminal SD.
Power supply
This inverter has a built-in AC reactor (FR-HAL) and a circuit type
specified in Harmonic suppression guideline in Japan is threephase bridge (capacitor smoothed) and with reactor (AC side).
(Refer to page 36)
A DC reactor (FR-HEL) can not be connected to the inverter.

Real sensorless vector control
Make sure to perform offline auto tuning before performing real
sensorless vector control.
The carrier frequencies are selectable from among 2k, 6k, 10k,
14kHz for real sensorless vector control.
Torque control can not be performed in the low speed (approx.
10Hz or less) regeneration range and with light load at low speed
(approx. 20% or less of rated torque at approx. 5Hz or less).
Choose vector control.
Performing pre-excitation (LX signal and X13 signal) under torque
control may start the motor running at a low speed even when the
start command (STF or STR) is not input. The motor may run also
at a low speed when the speed limit value=0 with a start command
input. Perform pre-excitation after making sure that there will be no
problem in safety if the motor runs.
Do not switch between the STF (forward rotation command) and
STR (reverse rotation command) during operation under torque
control. Overcurrent shut-off error (E.OC ) or opposite rotation
deceleration error (E.11) occurs.
When the inverter is likely to start during motor coasting under real
sensorless vector control, set to make frequency search of
automatic restart after instantaneous power failure valid (Pr. 57 ≠
"9999", Pr. 162 = "10").
Enough torque may not be generated in the ultra-low speed range
less than approx. 2Hz when performing real sensorless vector
control.
The guideline of speed control range is as shown below.
Driving:
1:200 (2, 4, 6 poles)
Can be used at 0.3Hz or more at rated 60Hz
1:30 (8, 10 poles)

will repeat due to a repeated flow of large current, shortening the
life from thermal fatigue. Since thermal fatigue is related to the
amount of current, the life can be increased by reducing current at
locked condition, starting current, etc. Decreasing current may
increase the life. However, decreasing current will result in
insufficient torque and the inverter may not start. Therefore, choose
the inverter which has enough allowance for current.
34
Precautions for Peripheral Device Selection
Installation and selection of moulded
case circuit breaker
Install a moulded case circuit breaker (MCCB) on the power
receiving side to protect the wiring of the inverter input side. For
MCCB selection, refer to page 31 since it depends on the inverter
power supply side power factor (which changes depending on the
power supply voltage, output frequency and load). Especially for a
completely electromagnetic MCCB, one of a slightly large capacity
must be selected since its operation characteristic varies with
harmonic currents. (Check it in the data of the corresponding
breaker.) As an earth leakage current breaker, use the Mitsubishi
earth leakage current breaker designed for harmonics and surge
sppression. (Refer to page 32.)
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.
Handling of primary side magnetic
contactor
For operation via external terminal (terminal STF or STR used),
provide an input side MC to prevent an accident caused by a natural
restart at power recovery after a power failure, such as an
instantaneous power failure, and to ensure safety for maintenance
work. Do not use this magnetic contactor to make frequent starts and
stops. (The switching life of the inverter input circuit is about
1,000,000 times. ) For parameter unit operation, an automatic restart
after power failure is not made and the MC cannot be used to make a
start. Note that the primary side MC may be used to make a stop but
the regenerative brake specific to the inverter does not operate and
the motor is coasted to a stop.
Handling of the secondary side
magnetic contactor
Switch the magnetic contactor between the inverter and motor only
when both the inverter and motor are at a stop. When the magnetic
contactor is turned on while the inverter is operating, overcurrent
protection of the inverter and such will activate. When an MC is
provided to switch to a commercial power supply, for example, it is
recommended to use bypass operation Pr.135 to Pr.139.
Thermal relay installation
The inverter has an electronic thermal relay function to protect the
motor from overheating. However, when running multiple motors
with one inverter or operating a multi-pole motor, provide a thermal
relay (OCR) between the inverter and motor. In this case, set the
electronic thermal relay function of the inverter to 0A. And for the
setting of the thermal relay, add the line-to line leakage current
(refer to page 36) to the current value on the motor rating plate.
For low-speed operation where the cooling capability of the motor
reduces, it is recommended to use a thermal protector or
thermistor-incorporated motor.
Measuring instrument on the output side
When the inverter-to-motor wiring length is large, especially in the
400V class, small-capacity models, the meters and CTs may
generate heat due to line-to-line leakage current. Therefore,
choose the equipment which has enough allowance for the current
rating.
To measure and display the output voltage and output current of the
inverter, it is recommended to use the terminal AM-5, FM-SD output
function of the inverter.
Disuse of power factor improving capacitor
(power capacitor)
The power factor improving capacitor and surge suppressor on the
inverter output side may be overheated or damaged by the
harmonic components of the inverter output. Also, since an
excessive current flows in the inverter to activate overcurrent
protection, do not install a capacitor or surge suppressor.
35
Wire thickness and wiring distance
When the wiring length between the inverter and motor is long, use
thick wires so that the voltage drop of the main circuit cable is 2% or
less especially at low frequency output. (A selection example for
the wiring distance of 20m is shown on page 31)
Especially at a long wiring distance, the maximum wiring length
should be within 500m since the overcurrent protection function
may be misactivated by the influence of a charging current due to
the stray capacitances of the wiring.
(The overall wiring length for connection of multiple motors should
be within 500m.)
The wiring length shold be 100m maximum for vector control.
Use the recommended connection cable when installing the
operation panel away from the inverter unit or when connecting the
parameter unit.
For remote operation via analog signal, wire the control cable
between the operation box or operation signal and inverter within
30m and away from the power circuits (main circuit and relay
sequence circuit) to prevent induction from other devices.
When using the external potentiometer instead of the parameter
unit to set the frequency, use a shielded or twisted cable, and do
not earth (ground) the shield, but connect it to terminal 5 as shown
below.

Earth (Ground)
When the inverter is run in the low acoustic noise mode, more
leakage currents occur than in the non-low acoustic noise mode
due to high-speed switching operation. Be sure to use the inverter
and motor after grounding (earthing) them. In addition, always use
the earth (ground) terminal of the inverter to earth (ground) the
inverter. (Do not use the case and chassis)
Noise
When performing low-noise operation at higher carrier frequency,
electromagnetic noise tends to increase. Therefore, refer to the
following measure example and consider taking the measures.
Depending on the installation condition, the inverter may be
affected by noise in a non-low noise (initial) status.
The noise level can be reduced by decreasing the carrier
frequency (Pr.72).
As measures against AM radio broadcasting noise and sensor
malfunction, common mode filter produces an effect.
As measures against induction noise from the power cable of
the inverter, providing a distance of 30cm (at least 10cm) or
more and using a twisted pair shielded cable as a signal cable
produces an effect. Do not earth (ground) shield but connect it
to signal common cable.
