powered ON as it is dangerous.
Do not touch the printed circuit board or handle the cables with
wet hands. Doing so may cause an electric shock.
Fire prevention
CAUTION
The inverter/converter must be installed on a nonflammable wall
without holes. Installing it to or near flammable material can
cause a fire.
If the inverter/converter has become faulty, its power must be
switched OFF. A continuous flow of large current may cause a
fire.
Be sure to perform daily and periodic inspections as specified in
the Instruction Manual. If the inverter/converter is used without
any inspection, a burst, breakage, or a fire may occur.
CAUTION
The voltage applied to each terminal must be as specified in the
Instruction Manual. Otherwise a burst, damage, etc. may occur.
The cables must be connected to the correct terminals.

3.4Installation of the converter and enclosure
design
When designing or manufacturing an enclosure, determine the structure, size, and device layout by fully considering the
conditions such as heat generation of the contained devices and the operating environment. The converter uses many
semiconductor devices. To increase reliability and prolong the life of the product, operate the converter in an environment that
sufficiently satisfies the standard environmental specifications.
3.4.1Converter installation environment
The following table lists the standard specifications of the converter installation environment. Using the converter in an
environment that does not satisfy the conditions deteriorates the performance, shortens the life, and causes a failure. Refer to
the following points, and take adequate measures.

Temperat ure
The permissible surrounding air temperature of the converter is between -10 and +50°C. Always operate the converter within
this temperature range. Operation outside this range will considerably shorten the service lives of the semiconductors, parts,
capacitors and others. Take the following measures to keep the surrounding air temperature of the converter within the
specified range.
(a) Measures against high temperature
• Use a forced ventilation system or similar cooling system. (Refer to page 26.)
• Install the enclosure in an air-conditioned electric chamber.
• Block direct sunlight.
• Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.
• Ventilate the area around the enclosure well.
(b) Measures against low temperature
• Provide a space heater in the enclosure.
• Do not power OFF the converter. (Keep the start signal of the inverter OFF.)
(c) Sudden temperature changes
• Select an installation place where temperature does not change suddenly.
• Avoid installing the converter near the air outlet of an air conditioner.
• If temperature changes are caused by opening/closing of a door, install the converter away from the door.
Humidity
Operate the converter within the ambient air humidity range of 45 to 90% (up to 95% with circuit board coating). Too high
humidity will pose problems of reduced insulation and metal corrosion. On the other hand, too low humidity may cause a
spatial electrical breakdown. The humidity conditions for the insulation distance defined in JEM 1103 standard "Insulation
Distance from Control Equipment" is 45 to 85%.
24
INSTALLATION AND WIRING
Page 26
Installation of the converter and enclosure design
(a) Measures against high humidity
• Make the enclosure enclosed, and provide it with a hygroscopic agent.
• Provide dry air into the enclosure from outside.
• Provide a space heater in the enclosure.
(b) Measures against low humidity
Air with proper humidity can be blown into the enclosure from outside. Also when installing or inspecting the unit, discharge
your body (static electricity) beforehand, and keep your body away from the parts and patterns.
(c) Measures against condensation
Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside air
temperature changes suddenly.
Condensation causes such faults as reduced insulation and corrosion.
• Take the measures against high humidity in (a).
• Do not power OFF the converter. (Keep the start signal of the inverter OFF.)
Dust, dirt, oil mist
Dust and dirt will cause such faults as poor contacts, reduced insulation and cooling effect due to the moisture-absorbed
accumulated dust and dirt, and in-enclosure temperature rise due to a clogged filter. In an atmosphere where conductive
powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time.
Since oil mist will cause similar conditions, it is necessary to take adequate measures.
Countermeasure
• Place the converter in a totally enclosed enclosure.
Take measures if the in-enclosure temperature rises. (Refer to page 26.)
• Purge air.
Pump clean air from outside to make the in-enclosure air pressure higher than the outside air pressure.
Corrosive gas, salt damage
If the converter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the
relays and switches will result in poor contact.
In such places, take the measures given in the previous paragraph.
Explosive, flammable gases
As the converter is non-explosion proof, it must be contained in an explosion-proof enclosure. In places where explosion may
be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and
has passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to
avoid installation in such places and install the converter in a non-hazardous place.
High altitude
Use the converter at an altitude of within 2500 m. For use at an altitude above 1000 m, consider a 3% reduction in the rated
current per 500 m increase in altitude.
If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric
strength.
3
Vibration, impact
The vibration resistance of the converter is up to 2.9 m/s2 at 10 to 55 Hz frequency and 1 mm amplitude for the directions of
X, Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors,
even if those vibration and impacts are within the specified values.
Especially when impacts are applied repeatedly, caution must be taken because such impacts may break the installation feet.
Countermeasure
• Provide the enclosure with rubber vibration isolators.
• Strengthen the structure to prevent the enclosure from resonance.
• Install the enclosure away from the sources of the vibration.

3.4.2Cooling system types for converter enclosure
From the enclosure that contains the converter, the heat of the converter and other equipment (inverter, transformers,
reactors, lamps, resistors, etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure
temperature lower than the permissible temperatures of the in-enclosure equipment including the converter.
The cooling systems are classified as follows in terms of the cooling calculation method.
(a) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)
(b) Cooling by heatsink (aluminum fin, etc.)
(c) Cooling by ventilation (forced ventilation type, pipe ventilation type)
(d) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

This system is for relatively small capacities.
Being a totally enclosed type, this system is the most
appropriate for hostile environment having dust, dirt, oil mist,
etc. The enclosure size increases depending on the converter
capacity.
This system has restrictions on the heatsink mounting position
and area. This system is for relatively small capacities.
This system is for general indoor installation. This is
appropriate for enclosure downsizing and cost reduction, and
often used.
This system is a totally enclosed type, and is appropriate for

3.4.3Installation of the converter
Placement of the converter
• Install the converter on a strong surface securely with screws.
• Leave enough clearances and take cooling measures.
• Avoid places where the converter is subjected to direct sunlight, high temperature and high humidity.
• Install the converter on a nonflammable wall surface.
• When encasing multiple converters in an enclosure, install them in parallel as a cooling measure.
• For heat dissipation and maintenance, keep clearance between the converter and the other devices or enclosure surface.
The clearance below the converter is required as a wiring space, and the clearance above the converter is required as a
heat dissipation space.
• When designing or building an enclosure for the converter, carefully consider influencing factors such as heat generation of
the contained devices and the operating environment.

Arrangement of multiple inverters and converters
When multiple inverters and converters are placed in the
same enclosure, generally arrange them horizontally as
shown in the figure (a). When it is inevitable to arrange
them vertically to minimize space as shown in the figure
(b), take such measures as to provide guides since heat
generated in the units in bottom row can increase the
temperatures in the units in top row, causing the failure of
the units in top row.

L24, and T4/L34) (c) except for those specified in the connection diagram. Doing so disrupts proper operation.
Securely perform grounding (earthing) by using the grounding (earthing) terminal.
Install an MC for each phase.
Install the UL listed fuse (refer to page 194) on the input side of the converter to meet the UL/cUL standards.
Always connect terminal RYA on the FR-A8AVP (installed on the converter) and the inverter terminal to which the X10 signal is assigned, and
connect terminal SE2 on the FR-A8AVP and the inverter terminal SD (terminal PC in the source logic). Failure to do so may lead to damage of
the converter.
Select a terminal S/L2 according to the input voltage.

Wiring of main circuit
For inverters other than the separated converter type of the FR-A802/F802
inverters, installation of a fuse on each cable is recommended to prevent
the spread of damage caused by an inverter failure. Select a fuse
according to the motor capacity. When using a motor, of which the capacity
is smaller than the inverter capacity by two ranks or more, select the fuse
with the capacity that is one rank lower than the inverter capacity. Refer to
the fuse selection tables on page 21.
For connection of multiple inverters, use the same gauge cable as the
inverter's power cable for wiring between the inverter main circuit terminal
(P/+ or N/-) and a junction terminal. (Refer to the Instruction Manual of the
inverter.)
The function needs to be assigned to an inverter terminal to be connected
to terminal RYA of the FR-A8AVP.

Earthing (Grounding) precautions
3.8Earthing (Grounding) precautions
Always earth (ground) the converter and the converter options.
Purpose of earthing (grounding)
Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use.
An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an
insulating material that can shut off a leakage current completely, and actually, a slight current flows into the case. The
purpose of earthing (grounding) the case of an electrical apparatus is to prevent operators from getting an electric shock from
this leakage current when touching it.
To avoid the influence of external noises, the earthing (grounding) is important to EMI-sensitive equipment that handle low-
level signals or operate very fast such as audio equipment, sensors, computers.
Earthing (grounding) system to be established
As described previously, the purpose of earthing (grounding) is roughly classified into the electrical shock prevention and the
prevention of malfunction due to the influence of electromagnetic noise. These two purposes should be clearly distinguished, and
the appropriate earth (ground) system must be established to prevent the leakage current having the converter's high frequency
components from reversing through another earth (ground) point for malfunction prevention by following these instructions:
• Make the separate earth (ground) connection for the converter and the converter options from any other devices and
equipment wherever possible.
Establishing adequate common (single-point) earth (ground) system (II) shown in the following figure is allowed only in
cases where the separate earth (ground) system (I) is not feasible. Do not make inadequate common (single-point) earth
(ground) connection (III).
As leakage currents containing many high frequency components flows into the earthing (grounding) cables of the
converter and the converter options, they must also be earthed (grounded) separately from the EMI-sensitive devices
described above.
In a high building, it may be effective to use its iron structure frames as earthing (grounding) electrode for EMI prevention in
order to separate from the earth (ground) system for electric shock prevention.
• Earthing (grounding) must conform to the requirements of national and local safety regulations and electrical codes (NEC
section 250, IEC 61140 class 1 and other applicable standards). A neutral-point earthed (grounded) power supply must be
used to be compliant with EN standard.
• Use the thickest possible earthing (grounding) cable. The earthing (grounding) cable should have the same or larger gauge
than the one indicated in the table on page 38.
• The earthing (grounding) point should be as close to the converter and the converter options as possible, and the earth
(ground) cable length should be as short as possible.
• Run the earthing (grounding) cable as far away as possible from the I/O wiring of the EMI-sensitive devices, and run them
3
in parallel in the minimum distance.

• The earthing (grounding) cable of the reactors should have the same gauge as the one for the earthing (grounding) cable of
the converter (refer to page 38).

reactors 1 and 2 are earthed (grounded) by being mounted on a panel of the enclosure).
If the inverter and the converter are installed far apart and the main circuit cables between them (P to P and N to N) are too

Common terminals of the control circuit (SD, PC, 5, SE)
• Terminals SD (sink logic), PC (source logic), 5, and SE are common terminals (0 V) for I/O signals. (All common terminals
are isolated from each other.) Do not earth (ground) these terminals. Avoid connecting terminal SD (sink logic) with terminal
5, terminal PC (source logic) with terminal 5, and terminal SE with terminal 5.
• In the sink logic, terminal SD is a common terminal for the contact input terminals (STF, STR, STP, RH, RM, RL, JOG, RT,
MRS, RES, AU, and CS) and the pulse train output terminal (FM
control circuit by photocoupler.
• In the source logic, terminal PC is a common terminal for the contact input terminals (STF, STR, STP, RH, RM, RL, JOG,
RT, MRS, RES, AU, CS). The open collector circuit is isolated from the internal control circuit by photocoupler.
• Terminal 5 is a common terminal for the analog output terminals AM and CA
using a shielded or twisted cable.
• Terminal SE is a common terminal for the open collector output terminals (OL, IPF, and FU). The contact input circuit is
isolated from the internal control circuit by photocoupler.
Terminal FM is provided in the FM-type converter.
Terminal CA is provided in the CA-type converter.

3.9.4Wiring precautions
• It is recommended to use a cable of 0.75 mm2 for connection to the control circuit terminals.
• The wiring length should be 30 m (200 m for terminal FM) at the maximum.
• Use two or more parallel micro-signal contacts or twin contacts to prevent
contact faults when using contact inputs since the control circuit input signals
are micro-currents.
• To suppress EMI, use shielded or twisted control cables, or install ferrite cores
to control cables, and run them away from the main and power circuits
(including the 200 V relay sequence circuit). For the cables connected to the control circuit terminals, connect their shields
to the common terminal of the connected control circuit terminal. When connecting an external power supply to terminal
PC, however, connect the shield of the power supply cable to the negative side of the external power supply. Do not directly
earth (ground) the shield to the enclosure, etc.
• Always apply a voltage to the fault output terminals (A2, B2, and C2) via a relay coil, lamp, etc.
• Separate the wiring of the control circuit away from the wiring of the main circuit.

• Terminal screw size: M4
• Cable gauge: 0.75 mm2 to 2 mm
• Tightening torque: 1.5 N·m
Connection method
When the protection circuit is activated, opening of the electromagnetic contactor (MC) on the input side of the converter
results in power loss in the control circuit of the converter, disabling the fault output signal retention. Terminals R1/L11 and S1/
L21 of the control circuit are provided to hold a fault signal. To use these terminals, add the node points joined to the control
circuit power supply terminals R1/L11 and S1/L21 on the MC power cable.
Terminals R1/L11 and S1/L21 are connected to terminals P/+ and N/- with a jumper respectively. Do not connect the power
cable to incorrect terminals. Doing so may damage the converter.

• The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than
the input side of the MC.
• When using a separate power supply connected to terminals R1/L11 and S1/L21, the necessary power capacity is 80 VA.
• If the main circuit power is switched OFF (for 0.1 seconds or more) then ON again, the converter is reset and a fault output
will not be held.

Starting and stopping the 24 V external power supply operation
• Supplying 24 V external power while the main circuit power is OFF starts the 24 V external power supply operation.
Likewise, turning OFF the main circuit power while supplying 24 V external power starts the 24 V external power supply
operation.
• Turning ON the main circuit power stops the 24 V external power supply operation and enables the normal operation.
NOTE
• When the 24 V external power is supplied while the main circuit power supply is OFF, the converter operation is disabled.
• In the initial setting, when the main power supply is turned ON during the 24 V external power supply operation, a reset is
performed in the converter, then the power supply changes to the main circuit power supply.
Confirming the 24 V external power supply input
• During the 24 V external power supply operation, "EV" blinks on the operation panel. The alarm lamp also blinks. Thus, the
24 V external power supply operation can be confirmed even when the operation panel is removed.

POWER ALARM
• During the 24 V external power supply operation, the 24 V external power supply operation (EV) signal is output. To use the
EV signal, set "68 (positive logic) or 168 (negative logic)" in any of Pr.192 to Pr.194 or Pr.196 (Output terminal function
selection) to assign the function to the output terminal.

Operation while the 24 V external power is supplied
• Fault history and parameters can be read and parameters can be written (when the parameter write from the operation
panel is enabled) using the operation panel keys.
• During the 24 V external power supply operation, monitoring function and signals related to the main circuit power supply
are not available (for example, monitoring the bus voltage or outputting the IPF signal is disabled).
• The alarms, which have occurred when the main circuit power supply is ON, continue to be output after the power supply is
changed to the 24 V external power supply. Perform the converter reset or turn OFF then ON the power to reset the faults.
NOTE
• Inrush current equal to or higher than the 24 V external power supply specification may flow at power-ON. Confirm that the
power supply and other devices are not affected by the inrush current and the voltage drop caused by it. Depending on the
power supply, the inrush current protection may be activated to disable the power supply. Select the power supply and
capacity carefully.
• When the wiring length between the external power supply and the converter is long, the voltage often drops. Select the
appropriate wiring size and length to keep the voltage in the rated input voltage range.
• In a serial connection of several inverters, the current increases when it flows through the inverter wiring near the power
supply. The increase of the current causes voltage to drop further. Use the converter and inverters after confirming that the
input voltage of each inverter is within the rated input voltage range. Depending on the power supply, the inrush current
protection may be activated to disable the power supply. Select the power supply and capacity carefully.
• "E.P24" may appear when the power supply start-up time is too long for the 24 V external power supply operation.
• "E.P24" may appear when the 24 V external power supply input voltage is low. Check the external power supply input.
• Do not touch the control circuit terminal block (circuit board) during the 24 V power supply operation (when conducted). Doing
so may cause an electric shock or burn.

Connection of the converter and multiple inverters
3.11 Connection of the converter and multiple
inverters
Up to 10 inverters are connectable to a single converter. Be sure to use the converter with the capacity equal to or higher than
the total capacity of inverters/motors. Additionally, the total capacity of the inverters or motors needs to be equal to or higher
than half the capacity of the converter. (Converter capacity × 1/2 ≤ total capacity of connected inverters or motors ≤ converter
capacity)
If the total inverter capacity or the total motor capacity is less than half the capacity of the converter, the converter can be used
as a common converter or a regenerative converter. However, its harmonic suppression effect reduces.
• Junction terminals and cross wiring may be required for the wiring of the multiple inverters. For the gauge of cable used
between the two junction terminals, refer to the descriptions in the following figure. Total capacity of higher-number axis
inverters must be considered for the cable selection.
• For the multiple inverter connection, place the higher capacity inverter in the lower number axis.
• It is recommended to install a fuse for each inverter according to the capacity of motor connected to the inverter as shown
in the following figure. Select a fuse according to the motor capacity.
When using a motor, of which the capacity is smaller than the inverter capacity by two ranks or more, select the fuse with
the capacity that is one rank lower than the inverter capacity. (Refer to page 21.)
• Keep the length of cables between the converter and the final axis inverter on each terminal within 50 m.

• Calculation of equivalent capacity P0 of harmonic generating equipment
"Equivalent capacity" is the capacity of a 6-pulse converter converted from the capacity of consumer's harmonic generating
equipment and is calculated by the following equation: If the sum of equivalent capacities is higher than the limit (refer to
page 70), harmonics must be calculated by the equation in next subheading.
Reference
capacity
P0 = Σ (Ki × Pi) [kVA]
Ki: Conversion factor (Refer to page 69.)
Pi: Rated capacity of harmonic generating
equipment[kVA]
Rated capacity: Determined by the capacity of the applied
motor and found in Table 5. The rated capacity used here
is used to calculate the generated harmonic amount and
is different from the power supply capacity required for
actual inverter drive.
i: Number indicating the conversion circuit type
• Calculation of outgoing harmonic current
Outgoing harmonic currents = fundamental wave current (value converted from received power voltage) × operation ratio ×
harmonic contents
• Operation ratio: actual load factor × operation time ratio during 30 minutes
• Harmonic content: Refer to page 70.
• Rated capacities and outgoing harmonic currents of inverter-driven motors

Install an AC reactor (FR-HAL) on the AC side of the inverter or a DC reactor (FR-HEL) on its DC side, or
install both to suppress outgoing harmonic currents.
The converter switches the converter section ON/OFF to reshape an input current waveform into a sine
wave, greatly suppressing harmonics. Use the converter with the dedicated options such as the phase
detection transformer box, AC reactor, and filter capacitor.
When used with a reactor connected in series, the power factor improving correction capacitor can
absorb harmonic currents.
Use two transformers with a phase angle difference of 30° in combinations of to ∆ and ∆ to ∆, to
provide an effect corresponding to 12 pulses, reducing low-degree harmonic currents.
A capacitor and a reactor are used together to reduce impedances at specific frequencies. Harmonic
currents are expected to be absorbed greatly by using this technique.
This filter detects the current in a circuit generating a harmonic current and generates a harmonic current
equivalent to a difference between that current and a fundamental wave current to suppress the
harmonic current at the detection point. Harmonic currents are expected to be absorbed greatly by using
this technique.

4.3Techniques and measures for
electromagnetic compatibility (EMC)
4.3.1Countermeasures against inverter-generated
EMI
In this section, electromagnetic noises refer to the high frequency (the 40th to 50th order harmonics) of irregular waveform in
a power distribution system.
Some electromagnetic noises enter the converter to cause the converter malfunction, and others are radiated by the
converter to cause the peripheral devices to malfunction. (The former is called EMS problem, the latter is called EMI problem,
and both is called EMC problem.) Though the high power factor converter is designed to be immune to noises, it requires the
following basic measures and EMS measures as it handles low-level signals. The high power factor converter chops output
voltage at high carrier frequency, it could generate noises. In a system including the converter, the noise created by the
system increases when both the converter and an inverter are operated. If these noises cause peripheral devices to
malfunction, EMI measures should be taken to suppress noises. Techniques differ slightly depending on EMI paths.
Basic techniques
• Do not run the power cables (I/O cables) and signal cables of the converter in parallel with each other and do not bundle
them.
• Use shielded twisted pair cables for the detector connecting and control signal cables and connect the sheathes of the
shielded cables to terminal SD.
• Ground (earth) devices such as the reactor 1, reactor 2, phase detection transformer box, and converter at one point.
(Refer to page 47.)
• Install the recommended noise filter on the converter (refer to page 76). The noise filter is effective against the noises that
enter the converter and the noises that are radiated from the converter.
• Do not earth (ground) the shields of the communication or control cables of the converter or inverter.
EMS measures to reduce electromagnetic noises that enter the
converter and cause it to malfunction
When devices that generate many electromagnetic noises (which use magnetic contactors, electromagnetic brakes, many
relays, for example) are installed near the converter and the converter may malfunction due to electromagnetic noises, the
following countermeasures must be taken.
• Provide surge suppressors for devices that generate many electromagnetic noises to suppress electromagnetic noises.
• Install data line filters to signal cables.
• Ground (Earth) the shields of the detector connection and control signal cables with cable clamp metal.

Techniques and measures for electromagnetic compatibility (EMC)
EMI measures to reduce electromagnetic noises that are radiated by the
converter to cause the peripheral devices to malfunction
Converter-generated noises are largely classified into those radiated by the converter itself and by the cables (I/O) connected
to its main circuit, those electromagnetically and electrostatically induced to the signal cables of the peripheral devices close
to the power cable connected to the converter main circuit, and those transmitted through the power cables.

Measure
When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g.
instruments, receivers and sensors, are contained in the enclosure that contains the converter or when their signal
cables are run near the converter, the devices may malfunction due to by air-propagated electromagnetic noises.
The following measures must be taken:
• Install the easily affected devices as far away from the converter and the inverter as possible.
• Place the easily affected signal cables as far away from the converter and the inverter as possible.
• Do not run the signal cables and power cables (converter I/O cables) in parallel with each other and do not bundle
them.
• Install the recommended noise filters (refer to page 76) or the radio noise filters (FR-BIF) on the input side of the
converter, and install the line noise filters (FR-BLF, or non-Mitsubishi product RC5128
FT-3KL F
) on the output side of the inverter to suppress radiated noises from the cables.
or FINEMET
• Use shielded cables as signal cables and power cables and run them in individual metal conduits to produce
further effects.
When the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction
noises may be propagated to the signal cables to cause malfunction of the devices. The following measures must
be taken:
• Install the easily affected devices as far away from the converter and the inverter as possible.
• Place the easily affected signal cables as far away from the converter and the inverter as possible.
• Do not run the signal cables and power cables (I/O cables of the converter and inverter) in parallel with each other
and do not bundle them.
• Use shielded cables as signal cables and power cables and run them in individual metal conduits to produce
further effects.
When the power supplies of the peripheral devices are connected to the power supply of the converter in the same
line, converter-generated noises may flow back through the power supply cables to cause malfunction of the
devices. The following measures must be taken:
• Install the recommended noise filter on the power input cables of the converter.
• Install a line noise filter (FR-BLF, RC5128
, FINEMET
®
FT-3KM F / FT-3KL F series) to the power output
cables of the inverter.
When a closed loop circuit is formed by connecting the peripheral devices wiring to the converter, leakage currents
may flow through the earthing (grounding) cable of the converter to cause the devices to malfunction. In that case,
disconnecting the earthing (grounding) cables from the devices may stop the malfunction of the devices.

NOTE
• Observe the instructions given in the Instruction Manual of each component.
• The damping resistor (FR-ABR) requires 5 cm clearance or more around it for directions. Besides, the distance between the
damping resistors should be 1 cm or more.
• As a reference, the surface temperature increase of the damping resistor (FR-ABR) is about 30°C and the total resistance
loss is about 300 W (dependent on the environment).
• For the converters not shown in the table above, installing the recommended noise filter is not required.
If leakage current from the inverter and/or the converter flows along the path shown in the following figure, installing a line

Adjusting DC voltage fluctuation (Pr.80 and Pr.81)
• Adjust the fluctuation range of the DC voltage by setting Pr.80.
Increasing the setting value reduces the DC voltage fluctuation caused by external disturbance.
• Adjust the recovery time to the commanded value at a fluctuation of DC voltage by setting Pr.81.
Increasing the setting value shortens the recovery time from the DC voltage fluctuation caused by external disturbance.
NOTE
• Setting Pr.80 too large makes the operation unstable.
• Setting only Pr.81 makes the operation unstable.
Setting the current limit level (Pr.22, Pr.23, Pr.157)
• Limit the output current not to exceed the specified value.
Set the current limit level by using Pr.22.
Current limit level at the regenerative operation can be individually set by setting a value other than "9999" to Pr.23.
Set the current limits as a percentage (set current limit ratios) with 100 being equal to the converter rated current in Pr.22

is available only on the FR-DU08. Negative values are displayed during regenerative driving regardless of the setting in Pr.290 Monitor
negative output selection.
Unsigned values are displayed on the FR-PU07 even during regenerative driving.
Parameter setting is not valid to set the item as the main monitor item on the parameter unit (FR-PU07). Use the monitor function of the FR-
PU07 for the setting.
The circle in this column indicates that the indication of negative signed numbers is available.

Monitoring I/O terminals on the operation panel (FR-DU08) (Pr.52)
• When Pr.52 = "55", the I/O terminal states can be monitored on the operation panel (FR-DU08).
• The I/O terminal monitor is displayed on the third screen.
• When a terminal is ON, the corresponding LED segment is ON. The center LED segments are always ON.
• On the I/O terminal monitoring screen (Pr.52 = "55"), the upper LEDs indicate the input terminal status, and the lower LEDs
indicate the output terminal status.

Cumulative energy monitoring and resetting (Pr.170, Pr.891)
• When the cumulative power is monitored (Pr.52 = "25"), the output power monitor value is added up and is updated in 100
ms increments. (The values are saved in EEPROM every hour.)
• The output power monitor value is added to the cumulative power monitor value during power driving, and is subtracted
from the cumulative power monitor value during regenerative driving.
• Increments and ranges of monitoring on the operation panel or parameter unit or via communication (RS-485
communication) are as follows.
On operation panel / parameter unitCommunication
RangeIncrement
0 to 999.99 kWh0.01 kWh
10000 to 99999 kWh1 kWh
Power is measured in the range of 0 to 99999.99 kWh, and the values are displayed in five digits. After the watt-hour meter (cumulative power
counter) reaches "999.99" (999.99 kWh), the meter displays values in 0.1 increments such as "1000.0" (1000.0 kWh).

• The decimal point position on the watt-hour meter can be shifted to left. The number of digits to be shifted is equal to the
setting of Pr.891 Cumulative power monitor digit shifted times.
For example, when the cumulative power is 1278.56 kWh and Pr.891 is set to "2", "12.78" is displayed (in 100's of units) on
the operation panel and the communication data is converted into "12".
• When Pr.891 = "0 to 4" and the cumulative value exceeds the upper limit, the decimal point position must be shifted. When
Pr.891 = "9999" and the cumulative value exceeds the upper limit, the meter returns to 0 and the counting starts again.
• Writing "0" in Pr.170 clears the cumulative power monitor.
NOTE
• When Pr.170 is read just after "0" has been written in Pr.170, the setting "9999" or "10" is displayed.
Monitoring cumulative energization time (Pr.563)
• Cumulative energization time monitoring (Pr.52 = "20") accumulates energization time of the converter every hour.
• When the cumulative energization time counter reaches 65535, it starts from 0 again. The number of times the cumulative
energization time counter reaches 65535 can be checked with Pr.563.

NOTE
• The cumulative energization time does not increase if the power is turned OFF after less than an hour.
• When the converter is used as an inverter before conversion, the total energization time for both before and after the
conversion is displayed.

Input power (with regenerative driving indication) (Pr.52 = "14")
• When input power is monitored and the regenerative driving indication is enabled (Pr.52 = "14"), values with a minus sign
are available for indication of the input power to the converter.
• The values of input power are displayed with unsigned numbers during power driving, and with signed numbers during
regenerative driving on the operation panel (FR-DU08).
[FR-DU08 indication for
regenerative driving]
The leftmost digit is used to indicate a minus sign.
• 999 kW is indicated when the input power value reaches 10000 kW for power driving, and -999 kW is indicated when the
value reaches -1000 kW for regenerative driving.
• Unsigned values are displayed on the FR-PU07 for both power driving and regenerative driving.
