the exposed high-voltage terminals or the charging part of the circuitry and get an
electric shock. Also, the inverter’s ability to withstand earthquakes will deteriorate.
zEven if power is off, do not remove the front cover except for wiring or periodic
inspection. You may access the charged inverter circuits and get an electric shock.
zBefore starting wiring or inspection, check to make sure that the 3-digit LED inverter
monitor is off, 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.
zThis inverter must be earthed (grounded). Earthing (grounding) must conform to
the requirements of national and local safety regulations and electrical codes.
(NEC section 250, IEC 536 class 1 and other applicable standards)
zAny person who is involved in the wiring or inspection of this equipment should be
fully competent to do the work.
zAlways install the inverter before wiring. Otherwise, you may get an electric shock
or be injured.
zPerform setting dial and key operations with dry hands to prevent an electric shock.
You may get an electric shock.
zDo not subject the cables to scratches, excessive stress, heavy loads or pinching.
Otherwise you may get an electric shock.
zDo not change the cooling fan while power is on. It is dangerous to change the
cooling fan while power is on.

CAUTION
zDo not fit capacitive equipment such as power factor correction capacitor, radio
noise filter (option FR-BIF(-H)) or surge suppressor to the output of the inverter.
zThe connection orientation of the output cables U, V, W to the motor will affect the
direction of rotation of the motor.
(3) Trial run
CAUTION
zCheck all parameters, and ensure that the machine will not be damaged by a
sudden start-up.
zWhen the load GD
output current may vary when the output frequency is in the 20Hz to 30Hz range.

CAUTION
zThe electronic thermal relay function does not guarantee protection of the motor
from overheating.
zDo not use a magnetic contactor on the inverter input for frequent starting/stopping
of the inverter.
zUse a noise filter to reduce the effect of electromagnetic interference. Otherwise
nearby electronic equipment may be affected.
zTake measures to suppress harmonics. Otherwise power supply harmonics from
the inverter may heat/damage the power capacitor and generator.
zWhen a 400V class motor is inverter-driven, please use an insulation-enhanced
motor or measures taken to suppress surge voltages. Surge voltages attributable to
the wiring constants may occur at the motor terminals, deteriorating the insulation of
the motor.
zWhen parameter clear or all clear is performed, reset the required parameters
before starting operations.
zThe inverter can be easily set for high-speed operation. Before changing its setting,
fully examine the performances of the motor and machine.
zIn addition to the inverter's holding function, install a holding device to ensure safety.
zBefore running an inverter which had been stored for a long period, always perform
inspection and test operation.
(5) Emergency stop
CAUTION
zProvide a safety backup such as an emergency brake which will prevent the
machine and equipment from hazardous conditions if the inverter fails.
zWhen the breaker on the inverter primary side trips, check for the wiring fault (short
circuit), damage of the inner parts of the inverter, etc. Identify the cause of the trip,
then remove the cause and power on the breaker.
zWhen any protective function is activated, take the appropriate corrective action,
then reset the inverter, and resume operation.

CAUTION
•If the wiring length of the FR-F540J-0.4K or 0.75K is 30m or more, use the
carrier frequency of 1kHz.
•When automatic torque boost is selected in Pr. 98 "automatic torque boost
selection (motor capacity)", the wiring length must be 30m maximum. (Refer
to page 133.)
•If the wiring distance between the inverter and motor is long, the motor torque
will decrease due to the voltage drop of the main circuit cable (especially at
low-frequency output).
Use thick cables so that a voltage drop is 2% or less.
8
Main circuit terminals
1.2.3Wiring instructions
1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
2) Application of power to the output terminals (U, V, W) of the inverter will damage the
inverter. Never perform such wiring.
3) After wiring, wire offcuts must not be left in the inverter (filter pack).
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter
clean.
When drilling mounting holes in an enclosure etc., take care not to allow chips and
other foreign matter to enter the inverter.
4) Use cables of the recommended size to make a voltage drop 2% maximum.
If the wiring distance is long between the inverter and motor, a main circuit cable
voltage drop will cause the motor torque to decrease especially at the output of a
low frequency.
5) For long distance wiring, the high response current limit function may be reduced or
the devices connected to the secondary side may malfunction or become faulty
under the influence of a charging current due to the stray capacity of wiring.
Therefore, note the maximum overall wiring length.
6) Electromagnetic wave interference
The input/output (main circuit) of the inverter includes high frequency components,
which may interfere with the communication devices (such as AM radios) used near
the inverter. When using the inverter without the filter pack, install a FR-BIF(-H)
optional radio noise filter (for use on the input side only) or FR-BSF01 or FR-BLF
line noise filter to minimize interference.
7) Do not install a power capacitor, surge suppressor or radio noise filter (FR-BIF(-H)
option) on the output side of the inverter.
This will cause the inverter to trip or the capacitor and surge suppressor to be
damaged. If any of the above devices are connected, remove them.
8) Before starting wiring or other work after the inverter is operated, wait for at least 10
minutes after the power supply has been switched off, and check that there are no
residual voltage using a tester or the like. The capacitor is charged with high
voltage for some time after power off and it is dangerous.

Main circuit terminals
1.2.4Selection of peripheral devices
Check the inverter type of the inverter you purchased. Appropriate peripheral devices
must be selected according to the capacity.
Refer to the following list and prepare appropriate peripheral devices:
*2. For installations in the United States or Canada, the
circuit breaker must be inverse time or instantaneous trip type.
*3. When the breaker on the inverter primary side trips, check for the wiring fault (short
circuit), damage to internal parts of the inverter, etc.
Identify the cause of the trip, then remove the cause and power on the breaker.
10
Main circuit terminals
1.2.5Leakage current and installation of earth (ground)
leakage circuit breaker
Due to static capacitances existing in the inverter I/O wiring and motor, leakage
currents flow through them. Since their values depend on the static capacitances,
carrier frequency, etc., take the following countermeasures.
(1) To-earth (ground) leakage currents
Leakage currents may flow not only into the inverter's own line but also into the
other line through the earth (ground) cable, etc.
These leakage currents may operate earth (ground) leakage circuit breakers and
earth (ground) leakage relays unnecessarily.
Countermeasures
• If the carrier frequency setting is high, decrease the carrier frequency (Pr. 72) of the
inverter.
Note that motor noise increases. Selection of Soft-PWM control (Pr. 70) will make it
unoffending. (Factory setting)
• By using earth leakage circuit breakers designed for harmonic and surge
suppression in the inverter's own line and other line, operation can be performed
with the carrier frequency kept high (with low noise).
REMARKS
When the filter pack is provided, leakage current can be reduced by removing the earth (ground)
cable for the capacitive filter and securing it with the supplied screw for leakage current
countermeasure (plastic) and spacer (plastic). However, the noise reduction effect of the
capacitive filter is lost.
(Pull out the earth (ground) cable for the capacitive filter a little to wire.)

Countermeasures
• Use the electronic thermal relay function of the inverter.
• Decrease the carrier frequency. Note that motor noise increases. Selection of
Soft-PWM (Pr. 70) makes it unoffending.
To ensure that the motor is protected against line-to-line leakage currents, it is
recommended to use a temperature sensor to directly detect motor temperature.
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 primary side. Select the MCCB according to the
power supply side power factor (which depends on the power supply voltage, output
frequency and load). Especially for a completely electromagnetic MCCB, one of a

designed for harmonics and surge suppression. (Refer to page 10 for the
recommended models.)

CAUTION
•Select the MCCB according to the inverter power supply capacity.
•Install one MCCB per inverter.
•The inverter has a protective function based on electronic overcurrent protection
(electronic thermal relay function) to protect the motor from overheating.
However, when running multiple motors with one inverter or operating a multipole motor, provide a thermal relay (OCR) between the inverter and motor. In this
case, set the electronic thermal relay function (electronic overcurrent protection)
of the inverter to 0A. And set the electronic overcurrent relay, add the line-to-line
leakage current to 1.0 times the current value at 50 Hz on the motor rating plate or
to 1.1 times the current value at 60 Hz.

•In the connection neutral point earth (grounded) system, the sensitivity
current becomes worse for earth (ground) faults on the inverter secondary
side. Earthing (Grounding) must conform to the requirements of national and
local safety regulations and electrical codes. (NEC section 250, IEC 536 class

•When the breaker is installed on the secondary side of the inverter, it may be
unnecessarily operated by harmonics if the effective value is less than the

1.2.6Power-off and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter's input side, it is recommended to provide an MC for the following
purposes. (Refer to page 10 for selection)
1) To release the inverter from the power supply when the inverter protective function
is activated or the drive becomes faulty (e.g. emergency stop operation)
2) To prevent any accident due to an automatic restart at restoration of power after an
inverter stop made by a power failure
3) To rest the inverter for an extended period of time
The control power supply for inverter is always running and consumes a little power.
When stopping the inverter for an extended period of time, powering off the inverter
will save power slightly.
4) To separate the inverter from the power supply to ensure safe maintenance and
inspection work
The inverter's input side MC is used for the above purpose, select class JEM1038AC3 for the inverter input side current when making an emergency stop during
normal operation.
REMARKS
The MC may be switched on/off to start/stop the inverter. However, since repeated inrush
currents at power on will shorten the life of the converter circuit (switching life is about 100,000
times), frequent starts and stops must be avoided. Turn on/off the inverter start controlling
terminals (STF, STR) to run/stop the inverter.
As shown on the right,
always use the start signal

(2) Handling of output side magnetic contactor
In principle, do not provide a magnetic contactor between the inverter and motor and
switch it from off to on during operation. If it is switched on during inverter operation, a
large inrush current may flow, stopping the inverter due to overcurrent shut-off. When
an MC is provided for switching to the commercial power supply, for example, switch it
on/off after the inverter and motor have stopped.

1.2.7Regarding the installation of the reactor
When the inverter is installed near a large-capacity power transformer (500kVA or
more with the wiring length of 10m (32.81feet) or less) or the power capacitor is to be
switched, an excessive peak current will flow in the power supply input circuit,
damaging the converter circuit. In such a case, always install the reactor (FR-HEL(-H)
/FR-BEL(-H) or FR-HAL(-H)/FR-BAL(-H)). Since the filter pack includes a power factor
improving DC reactor, a reactor need not be installed separately.

REMARKS
*When connecting the FR-HEL(-H)/FR-BEL(-H) (filter pack), remove the jumper across

The wiring length between the FR-HEL(-H)/FR-BEL(-H) and the inverter should be 5m
maximum and as short as possible.
Use the cables which are equal in size to those of the main circuit. (Refer to page 8)
CAUTION
•The power factor improving capacitor and surge suppressor on the inverter
output side may be overheated or damaged by the high frequency
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. Use a power factor improving reactor for power factor
improvement.
•If a surge voltage occurs in the power supply system, this surge energy may
flow into the inverter, causing the inverter to display OV1, OV2 or OV3 and
come to an alarm stop. In such a case, also install the optional FR-HEL(-H)/FRBEL(-H) or FR-HAL(-H)/FR-BAL(-H) power factor improving reactor.

Regarding noise (EMI) and the installation of a noise filter
Some noise enters the inverter causing it to malfunction and others are generated by
the inverter causing the malfunction of peripheral devices. Though the inverter is
designed to have high immunity performance, it handles low-level signals, so it
requires the following general countermeasures to be taken.
(1) General countermeasures
• Do not run the power cables (I/O cables) and signal cables of the inverter in parallel
with each other and do not bundle them.
• Use twisted shield cables for the detector connecting and control signal cables and
connect the sheathes of the shield cables to terminal SD.
• Earth (Ground) the inverter, motor, etc. at one point.
• Capacitances exist between the inverter's I/O wiring, other cables, earth (ground)
and motor, through which leakage currents flow to cause the earth leakage circuit
breaker, earth (ground) leakage relay and external thermal relay to operate
unnecessarily. To prevent this, take appropriate measures, e.g. set the carrier
frequency in Pr. 72 to a low value, use an earth (ground) leakage circuit breaker
designed for suppression of harmonics and surges, and use the electronic thermal
relay function built in the inverter.
• The input and output of the inverter main circuit include high-degree harmonics,
which may disturb communication devices (AM radios) and sensors used near the
inverter.

Main circuit terminals
1.2.9Earthing (Grounding) precautions
z Leakage currents flow in the inverter (filter pack). To prevent an electric shock, the
inverter (filter pack) and motor must be earthed (grounded). Earthing (Grounding)
must conform to the requirements of national and local safety regulations and
electrical codes.
(NEC section 250, IEC 536 class 1 and other applicable standards)
z Use the dedicated earth (ground) terminal to earth (ground) the inverter (filter pack).
(Do not use the screw in the casing, chassis, etc.)
Use a tinned* crimping terminal to connect the earth (ground) cable. When
tightening the screw, be careful not to damage the threads.
*Plating should not include zinc.
z Use the thickest possible earth (ground) cable. Use the cable whose size is equal to
or greater than that indicated in the following table, and minimize the cable length.
The earthing (grounding) point should be as near as possible to the inverter.
For use as a product compliant with the Low Voltage Directive, use PVC cable
whose size is indicated within parentheses.
)
z As a noise reduction technique, use one wire of the four-core cable with the earth
(ground) terminal of the motor, and earth (ground) at one point from the filter pack
side via the inverter. (Refer to page 2.)

1.2.10 Power supply harmonics
The inverter may generate power supply harmonics from its converter circuit to affect
the power generator, power capacitor etc. Power supply harmonics are different from
noise and leakage currents in source, frequency band and transmission path. Take the
following countermeasure suppression techniques.
The following table indicates differences between harmonics and noise:

Harmonic currents produced
on the power supply side by
the inverter change with such
conditions as whether there
are wiring impedances and a
DC reactor (FR-HEL(-H)/FRBEL(-H) or FR-HAL(-H)/FRBAL(-H)) and the magnitudes
of output frequency and
output current on the load
side.
For the output frequency and output current, we understand that they should be
calculated in the conditions under the rated load at the maximum operating frequency.
CAUTION
The power factor improving capacitor and surge suppressor on the inverter
output side may be overheated or damaged by the high frequency components
of the inverter output. Also, since an excessive current flows in the inverter to
activate overcurrent protection, do not provide a capacitor and surge
suppressor on the inverter output side when the motor is driven by the inverter.
To improve the power factor, insert a reactor on the inverter's primary side or
DC circuit. For full information, refer to page 16.

1.2.11 Harmonic suppression guideline
Harmonic currents flow from the inverter to a power receiving point via a power
transformer. The harmonic suppression guideline was established to protect other
consumers from these outgoing harmonic current.
The three-phase 200V input specifications 3.7kW or less are previously covered by
"Harmonic suppression guideline for household appliances and general-purpose
products" and other models are covered by "Harmonic suppression guideline for
consumers who receive high voltage or special high voltage". However, the generalpurpose inverter has been excluded from the target products covered by "Harmonic
suppression guideline for household appliances and general-purpose products" in
January 2004. Later, this guideline was repealed on September 6, 2004. All capacities
of all models are now target products of "Harmonic suppression guideline for
consumers who receive high voltage or special high voltage" (hereinafter referred to
as "Guideline for specific consumers").
"Guideline for specific consumers"
This guideline sets forth the maximum values of harmonic currents outgoing from a
high-voltage or especially high-voltage consumer who will install, add or renew
harmonic generating equipment. If any of the maximum values is exceeded, this
guideline requires that consumer to take certain suppression measures.

1) Calculation of equivalent capacity (P0) of harmonic generating equipment
The "equivalent capacity" is the capacity of a 6-pulse converter converted from the
capacity of consumer's harmonic generating equipment and is calculated with the
following equation. If the sum of equivalent capacities is higher than the limit in
Table 3, harmonics must be calculated with the following procedure:
P0=Σ (Ki × Pi) [kVA]
Ki: Conversion factor (refer to Table 2)
Pi: Rated capacity of harmonic
generating equipment* [kVA]
i: Number indicating the conversion
circuit type
* Rated capacity: Determined by the
capacity of the applied motor and
found in Table 5. It should be noted
that the rated capacity used here is
used to calculate a generated
harmonic amount and is different
from the power supply capacity
required for actual inverter drive.
2) Calculation of outgoing harmonic current
Outgoing harmonic current = fundamental wave current (value converted from
received power voltage) × operation ratio × harmonic
content
• Operation ratio: Operation ratio = actual load factor × operation time ratio during
30 minutes
• Harmonic content: Found in Table 4.

1.2.12 Inverter-driven 400V class motor
In the PWM type inverter, a surge voltage attributable to wiring constants is generated
at the motor terminals. Especially for a 400V class motor, the surge voltage may
deteriorate the insulation. When the 400V class motor is driven by the inverter,
consider the following measures:
•Measures
It is recommended to take either of the following measures:
(1) Rectifying the motor insulation
For the 400V class motor, use an insulation-enhanced motor. Specifically
1) Specify the "400V class inverter-driven, insulation-enhanced motor".
2) For the dedicated motor such as the constant-torque motor and low-vibration
motor, use the "inverter-driven, dedicated motor".
CAUTION
When the wiring length between the motor and inverter is 40m or more, take
the above countermeasure and also set the long wiring mode in Pr. 70 "SoftPWM setting". (Refer to page 114 for Pr. 70.)
(2) Suppressing the surge voltage on the inverter side
On the secondary side of the inverter, connect the optional surge voltage
suppression filter (FR-ASF-H).

CAUTION
•Make sure that the front cover is installed securely.
•The front cover is fitted with the capacity plate and the inverter unit with the
rating plate. Since these plates have the same serial numbers, always replace
the removed cover onto the original inverter.
•The sink-source logic change-over jumper connector must be fitted in only
one of those positions. If it is fitted in both positions at the same time, the
inverter may be damaged.

operation, refer to page 32.)
3) After the start signal has been input, the inverter starts operating when the
frequency setting signal reaches or exceeds the "starting frequency" set in Pr. 13
(factory-set to 0.5Hz).
If the motor load torque is large or the "torque boost" set in Pr. 0 is small, operation
may not be started due to insufficient torque until the inverter output frequency
reaches about 3 to 6Hz.
If the "minimum frequency" set in Pr. 2 (factory setting = 0Hz) is 6Hz, for example,
merely entering the start signal causes the running frequency to reach the
minimum frequency of 6Hz according to the "acceleration time" set in Pr. 7.
4) To stop the motor, operate the DC injection brake for the period of "DC injection

To disable the DC injection brake function, set 0 in either of Pr. 11 "DC injection
brake operation time" or Pr. 12 "DC injection brake voltage".
In this case, the motor is coasted to a stop at not more than the frequency set in
Pr. 10 "DC injection brake operation frequency" (0 to 120Hz variable) or at not
more than 0.5Hz (when the DC injection brake is not operated).

signal is input during reverse rotation, the inverter is decelerated and then
switched to the opposite output without going through the stop mode.

is disabled and restart is made.
*3. The "DC injection brake operation time" in Pr. 11 (factory-set to 0.5s) may be set between
0 and 10s.
*4. The frequency at which the motor is coasted to a stop is not more than the "DC injection

(2) Three-wire type connection (STF, STR, STOP)
A three-wire type connection is shown on
the right. Assign the start self-holding
signal (STOP) to any of the input terminals.
To make a reverse rotation start, set Pr. 63
Power
supply
to "- - -" (factory setting).
1) Turning the STOP signal on makes start
self-holding function valid. In this case,
the forward/reverse rotation signal
functions only as a start signal.
(Note) Assign the stop signal to any of
Pr. 60 to Pr. 62 (input terminal
function selection).
2) Even if the start signal STF (STR) is
turned on once then off, the start signal
is kept on and starts the inverter. When
changing the direction of rotation, turn
the start signal STR (STF) on once and
then off.
3) To stop the inverter, turning off the STOP
signal once decelerates it to a stop.For
the frequency setting signal and the
operation of DC injection brake at a stop
time, refer to paragraphs 2) to 4) in (1)
Two-wire type connection. The right
diagram shows 3-wire type connection.
4) When the JOG signal is on, the STOP signal is invalid and the JOG signal has
precedence.
5) When the output stop signal MRS is turned on, the inverter output is shutoff.
However, self-holding function is not deactivated and the start signal is held.

For the relationships between the frequency setting input voltages (currents) and
output frequencies, refer to the following diagram. The frequency setting input signals
are proportional to the output frequencies. Note that when the input signal is less than
the starting frequency, the output frequency of the inverter is 0Hz.

1.4.4Indicator connection and adjustment (FM)
The output frequency, etc. of the inverter can be indicated by a DC ammeter of 1mA
full-scale deflection and maximum 300Ω internal resistance or a commercially
available digital indicator which is connected across terminals FM-SD.
The indicator can be calibrated from the operation panel or parameter unit. Note that
the reading varies according to the wiring distance if the indicator is placed away from
the inverter. In this case, connect a calibration resistor in series with the indicator as
shown below and adjust until the reading matches the operation panel or parameter
unit indication (indicator monitoring mode).
Install the indicator within 200m (50m for the digital indicator) of the inverter and
connect them by at least 0.3mm

Terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM,
AU) and frequency output signal (FM).
Terminal 5 is a common terminal for the frequency setting analog input signals. It
should be protected from external noise using a shielded or twisted cable.
Terminal SE is a common terminal for the open collector output terminal (RUN).

1.5.8Reset signal: Pr. 60 to Pr. 63 setting "10"
Used to reset the alarm stop state established when the inverter's protective function
is activated. The reset signal immediately sets the control circuit to the initial (cold)
status, e.g. initializes the electronic thermal relay function protection circuit. It shuts off
the inverter output at the same time. During reset, the inverter output is kept shut off.
To give this reset input, short terminals RES-SD for more than 0.1s. When the shorting
time is long, the operation panel or parameter unit displays the initial screen, which is
not a fault.
After opening terminals RES-SD (about 1s), operation is enabled.
The reset terminal is used to reset the inverter alarm stop state. If the reset terminal is
shorted, then opened while the inverter is running, the motor may be restarted during
coasting (refer to the timing chart below) and the output may be shut off due to
overcurrent or overvoltage.
Setting either "1" or "15" in reset selection Pr. 75 allows the accidental input of the
reset signal during operation to be ignored.

1.8Design information
1) Provide electrical and mechanical interlocks for MC1 and MC2 which are used for
bypass operation.
When the wiring is incorrect and if there is a bypass operation circuit as shown
below, the inverter will be damaged by leakage current from the power supply due
to arcs generated at the time of switch-over or chattering caused by a sequence
error.
2) If the machine must not be restarted when power is restored after a power failure,
provide a magnetic contactor in the inverter's primary side and also make up a
sequence which will not switch on the start signal.
If the start signal (start switch) remains on after a power failure, the inverter will
automatically restart as soon as the power is restored.
3) Use two or more parallel micro-signal contacts or twin contacts to prevent a contact
fault when using contact inputs since the control circuit input signals are microcurrents.
4) Do not apply a large voltage to the contact input terminals (e.g. STF) to the control
circuit.
5) Always apply a voltage to the alarm output terminals (A, B, C) via a relay coil, lamp
etc.
6) Make sure that the specifications and rating match the system requirements.

1.9Failsafe of the system which uses the inverter
When a fault occurs, the inverter trips to output a fault signal. However, a fault output signal
may not be output at an inverter fault occurrence when the detection circuit or output circuit
fails, etc. Although Mitsubishi assures best quality products, provide an interlock which
uses inverter status output signals to prevent accidents such as damage to machine when
the inverter fails for some reason and at the same time consider the system configuration
where failsafe from outside the inverter, without using the inverter, is enabled even if the
inverter fails.
(1) Interlock method which uses the inverter status output signals
By combining the inverter status output signals to provide an interlock as shown
below, an inverter alarm can be detected.

The inverter running signal (RUN signal) is
output when the inverter is running (RUN signal is assigned to terminal RUN in the
initial setting).
Check if RUN signal is output when inputting the start signal to the inverter (forward
signal is STF signal and reverse signal is STR signal). For logic check, note that RUN
signal is output for the period from the inverter decelerates until output to the motor is
stopped, configure a sequence considering the inverter deceleration time.
4) Checking the motor operating status by the start signal input to the inverter and
inverter output current detection signal.
The output current detection signal (Y12 signal) is output when the inverter operates
and currents flows in the motor. Check if Y12 signal is output when inputting the start
signal to the inverter (forward signal is STF signal and reverse signal is STR signal).
Note that the current level at which Y12 signal is output is set to 120% of the inverter
rated current in the initial setting, it is necessary to adjust the level to around 20%
using no load current of the motor as reference with Pr.48 "Output current detection
level".
For logic check, as same as the inverter running signal (RUN signal), the inverter
outputs for the period from the inverter decelerates until output to the motor is
stopped, configure a sequence considering the inverter deceleration time.

Failsafe of the system which uses the inverter
(2) Backup method outside the inverter
Even if the interlock is provided by the inverter status signal, enough failsafe is not
ensured depending on the failure status of the inverter itself. For example, even if the
interlock is provided using the inverter fault output signal, start signal and RUN signal
output, there is a case where a fault output signal is not output and RUN signal is kept
output even if an inverter fault occurs.
Provide a speed detector to detect the motor speed and current detector to detect the
motor current and consider the backup system such as checking up as below
according to the level of importance of the system.
1) Start signal and actual operation check
Check the motor running and motor current while the start signal is input to the inverter
by comparing the start signal to the inverter and detected speed of the speed detector
or detected current of the current detector. Note that the motor current runs as the
motor is running for the period until the motor stops since the inverter starts
decelerating even if the start signal turns off. For the logic check, configure a
sequence considering the inverter deceleration time. In addition, it is recommended to
check the three-phase current when using the current detector.
2) Command speed and actual operation check
Check if there is no gap between the actual speed and commanded speed by
comparing the inverter speed command and detected speed of the speed detector.

<Setting>
•In Pr. 3 and Pr. 47, set the base frequency (motor's rated frequency).
Use the RT signal to switch between these two different base frequencies.
(Turn on the RT signal to make Pr. 47 valid.) (*)
When running the standard motor, generally set the "base frequency" to the rated
frequency of the motor. When running the motor using electronic bypass operation,
set the base frequency to the same value as the power supply frequency.
If only "50Hz" is given on the motor rating plate as the frequency, always set the
"base frequency" to "50Hz". If it remains at "60Hz", the voltage may become too low
and torque shortage occurs, resulting in an overload trip. Special care must be taken
when "1" is set in Pr. 14 "load pattern selection".
If "50Hz/60Hz" is given on the motor rating plate as the frequency, always set the
"base frequency" to "60Hz". When running the motor using commercial power
supply-inverter switch-over operation, set the base frequency to the same value as
the power supply frequency.

CAUTION
•When two or more motors are connected to the inverter, they cannot be
protected by the electronic thermal relay function. Install an external thermal
relay to each motor.
•When a difference between the inverter and motor capacities is large and the

The starting frequency at
which the start signal is
turned on can be set in the
range 0 to 60Hz.
Frequency which is output
by the inverter first at a start
and gives great influence to
the starting torque. About 1
to 3Hz for vertical lift
applications, or up to 5Hz to
the maximum. For other than
vertical lift applications,
factory setting of about
0.5Hz is recommended.

2.3.12 Stall prevention function and current limit function
(Pr. 21 )
You can make setting to prevent stall caused by overcurrent and/or to prevent the
inverter from resulting in an overcurrent trip (to disable fast-response current limit
that limits the current) when an excessive current flows due to sudden load
fluctuation or ON-OFF on the output side of a running inverter.
• Stall prevention
If the current exceeds the stall prevention operation level (Pr.22), the output
frequency of the inverter is automatically varied to reduce the current.
• High response current limit
If the current exceeds the limit value, the output of the inverter is shut off to
prevent an overcurrent.

FUNCTIONS
Explanation of functions (parameters)
CAUTION
•If the load is heavy or the acceleration/deceleration time is short, the stall
prevention may be activated and the motor not stopped in the preset
acceleration/deceleration time. Therefore, set optimum values to the Pr. 21
and stall prevention operation level.
•When the fast response current limit has been set in Pr. 21 (factory setting),
torque will not be provided at the Pr. 22 setting of 140% or higher. At this time,
make setting so that the fast response current limit is not activated.
•In vertical lift applications, make setting so that the fast response current limit
is not activated. Torque may not be produced, causing a drop due to gravity.
CAUTION
Always perform test operation.
Stall prevention operation performed during acceleration may increase the
acceleration time.
Stall prevention operation performed during constant speed may cause
sudden speed changes.
Stall prevention operation performed during deceleration may increase the
deceleration time, increasing the deceleration distance.

Explanation of functions (parameters)
2.3.13 Stall prevention (Pr. 22 , Pr. 23 , Pr. 28 )
Set the output current level (% value to the rated inverter output current) at
which the output frequency will be adjusted to prevent the inverter from stopping
due to overcurrent etc.
During high-speed operation above the rated motor frequency, acceleration
may not be made because the motor current does not increase. To improve
the operating characteristics of the motor in this case, the stall prevention
level can be reduced in the high frequency range. This function is effective for
performing operation up to the high speed range on a centrifugal separator
etc. Normally, set 60Hz in Pr. 28 "stall prevention operation reduction starting
frequency" and 100% in Pr. 23.

Explanation of functions (parameters)
REMARKS
When the fast response current limit is set in Pr. 21 "stall prevention function selection"
(factory setting), do not set any value above 140% in Pr. 22. The torque will not be developed
by doing so.
If the Pr. 22 value is set to higher than 140%, make setting in Pr. 21 to disable the high
response current limit.
In vertical lift applications, make setting so the fast response current limit is not activated.
Torque may not be produced, causing a drop due to gravity.
CAUTION
Do not set a small value as the stall prevention operation current. Otherwise,
torque generated will reduce.
Test operation must be performed.
Stall prevention operation during acceleration may increase the acceleration
time.
Stall prevention operation during constant speed may change the speed
suddenly.
Stall prevention operation during deceleration may increase the deceleration
time, increasing the deceleration distance.
* As the acceleration/deceleration time, set the time taken to reach the Pr. 3
"base frequency" value, not the Pr. 20 "acceleration/deceleration reference
frequency" value.

(Factory setting)
For machine tool spindle applications, etc.
Used when acceleration/deceleration must be made in a short
time to a high-speed range of not lower than the base
frequency. Acceleration/deceleration is made in a pattern
where fb (base frequency) acts as the inflection point of an S
shape, and you can set the acceleration/deceleration time
which matches the motor torque reduction in the constantoutput operation range of not lower than the base frequency.
For prevention of load shifting in conveyor and other
applications. Since acceleration/deceleration is always made in
an S shape from f2 (current frequency) to f1 (target frequency),
this function eases shock produced at acceleration/
deceleration and is effective for load collapse prevention, etc.
