loads or pinching. Doing so may cause an electric shock.
Do not change the cooling fan while the inverter/converter is
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.
Otherwise a burst, damage, etc. may occur.
The polarity (+ and -) must be correct. Otherwise a burst,
damage, etc. may occur.
While power is ON or for some time after power-OFF, do not
touch the inverter/converter, reactor 1, reactor 2, phase detection transformer box, filter capacitor, and inrush current limit resistor as they will be extremely hot. Doing so may cause a burn.
Additional instructions The following instructions must be also followed. If the inverter/
converter is handled incorrectly, it may cause an unexpected
fault, injury, or electric shock.

cover. Doing so may cause a fall or failure.
Do not stand or rest heavy objects on the inverter/converter.The installing orientation of the inverter/converter must be
correct.
Foreign conductive objects must be prevented from entering the
inverter/converter. That includes screws and metal fragments or other flammable substance such as oil.
As the inverter/converter is a precision instrument, do not drop
or subject it to impact.
The surrounding air temperature must be between 10 and +50°C
(non-freezing). Otherwise, the inverter/converter may be damaged.
The ambient humidity must be 95% RH or less (non-
condensing). Otherwise, the inverter/converter may be damaged. (For the details, refer to page 24.)
The temporary storage temperature (applicable to a short limited
time such as a transportation time) must be between -20 and +65°C. Otherwise, the inverter/converter may be damaged.
The inverter/converter must be used indoors (without corrosive
gas, flammable gas, oil mist, dust and dirt etc.) Otherwise, the inverter/converter may be damaged.
The inverter/converter must be used at an altitude of 2500 m or
less, with 2.9 m/s X, Y, Z axes). Otherwise, the inverter/converter may be damaged. (For the details, refer to page 24.)
If halogen-based materials (fluorine, chlorine, bromine, iodine,
etc.), included in fumigants to sterilize or disinfect wooden packages, infiltrate into this product, the product may be damaged. Prevent residual fumigant components from being infiltrated into the package, or use an alternative sterilization or disinfection method (heat disinfection, etc.). Note that sterilization or disinfection of wooden package should be performed before packing.

WARNING
Usage
Any person must stay away from the equipment when the retry
function is set as the inverter/converter will restart suddenly after its output shutoff.
Depending on the function settings, the inverter/converter does
not stop its output even when the STOP/RESET key on the operation panel is pressed. To prepare for it, provide a separate circuit and switch (to turn OFF the power or to take other actions) for an emergency stop.
Be sure to turn OFF the start (STF/STR) signal before clearing
the fault as the inverter/converter will restart the motor suddenly after a fault clear.
Use only the specified inverters for the connection with the
converter. Connection of any other electrical equipment to the output of the converter may damage the equipment.
Do not modify the inverter/converter.Do not remove any part which is not instructed to be removed in
the Instruction Manual. Doing so may lead to a failure or damage.
CAUTION
Usage
Do not start or stop the inverter/converter frequently with a
magnetic contactor on its input side. Doing so may shorten the life of the inverter/converter.
Use a noise filter or other means to minimize the
electromagnetic interference with other electronic equipment used nearby the inverter/converter.
As all parameters return to their initial values after the Parameter
clear or All parameter clear is performed, the parameters must be set again as required before the operation is started.
Before running an inverter/converter which have been stored
and not been operated for a long period, perform an inspection and a test operation.
To avoid damage due to static electricity, static electricity in your
body must be discharged before you touch the inverter/ converter.
Emergency stop
A safety backup such as an emergency brake must be provided
for devices or equipment in a system to prevent hazardous conditions in case of failure of the inverter/converter or its external controller.
If a breaker on the input side of the inverter/converter is tripped,
the wiring must be checked for a fault (such as short circuit), and internal parts of the inverter/converter for a damage, etc. The cause of the trip must be identified and removed before turning ON the power of the breaker.
When any fault occurs, take an appropriate corrective action,
then reset the inverter/converter, and resume the operation.
Maintenance, inspection and parts replacement
Do not carry out a megger (insulation resistance) test on the
control circuit of the inverter/converter.

Installation of the converter and enclosure design

3.4 Installation 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.

3.4.1 Converter 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.

3.4.2 Cooling 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 low in cost and generally used, but the enclosure size increases as the converter capacity increases. 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.

3.4.3 Installation 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.

Placement of the ventilation fan and converter
Heat generated in the converter is blown up from the bottom of
the unit as warm air by the cooling fan. When installing a
ventilation fan for that heat, determine the place of ventilation
fan installation after fully considering an air flow. (Air passes
through areas of low resistance. Make an airway and airflow
plates to expose the converter to cool air.)

3.4.4 Protruding the heatsink through a panel

When encasing the converter to an enclosure, the heat generated in the enclosure can be greatly reduced by protruding its
heatsink through the rear panel of the enclosure. To protrude the heatsink, refer to the FR-A802 Instruction Manual

 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.

NOTE
• To use inverters equipped with terminals R1/L11 and S1/L21 other than the separated converter type of the FR-A802 or FR-
F802 inverters, remove jumpers across main circuit terminals R/L1 and R1/L11 and across S/L2 and S1/L21 on the inverter
(refer to the Instruction Manual of the inverter).
• Terminals R1/L11 and S1/L21 on the inverter are control power input terminals. If the terminals are left open, the inverter
output may be shut off by an activation of a protective function, or the inverter may be damaged.
• If the FR-A842/F842 inverters are connected to the converter, and the inverter control power is supplied via terminals P/+ and
N/- (initial setting), a protective function (E.P24) may be activated in the inverter at the occurrence of a power shutoff.

Earthing (Grounding) precautions

3.8 Earthing (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.
Converter and converter options
(I) Separate earthing (grounding): Good

(II) Common (single-point) earthing (grounding): OK

Converter and converter options
(III) Inadequate common (single-point) earthing (grounding): Bad

Earthing (grounding) of the reactors
• Use the earth (ground) terminal for earthing (grounding) of the reactor 1 and reactor 2. (Refer to page 178 to check the
earth (ground) terminal position.)
• 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).

Connected in series with all the thermostat output terminals on the reactors 1 and 2.
The External thermal relay input (OH) signal is used when using the external thermal relay or the thermal protector built into the motor to protect the motor from overheating. When the thermal relay is activated, the inverter output is shut off by the external thermal relay operation (E.OHT) of the converter.
Use this signal to reset a fault output provided when a protective function is activated. Turn ON the RES signal for 0.1 second or longer, then turn it OFF. In the initial setting, reset is always enabled. By changing the Pr.75 setting, reset input is enabled only when a protective function of the converter is activated. The converter recovers about 1 second after the reset is released.
Connect auxiliary contacts of an inrush current limit resistor's MC (normally-open) and inrush current limit resistors (with thermostat) (normally­closed) to stop the converter operation when overheating of the resistor becomes a concern or when a filter capacitor is faulty.
No function is assigned in the initial setting. Use Pr.186 to assign a function to the terminal.

Wiring method
• Power supply connection
For the control circuit wiring, strip off the sheath of a cable, and use it with a blade terminal. For a single wire, strip off the
sheath of the wire and apply directly.
Insert the blade terminal or the single wire into a socket of the terminal.
(1) Strip off the sheath for the below length. If the length of the sheath peeled is too long, a short circuit may occur with
neighboring wires. If the length is too short, wires might come off.
Wire the stripped cable after twisting it to prevent it from becoming loose. In addition, do not solder it.

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

3.9.4 Wiring 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.
Make cuts in rubber bush of the converter side and lead wires.

• 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.

NOTE
• When using separate power supplies, always remove the jumpers connected to terminals R1/L11 and S1/L21. Failure to do
so may lead to damage of 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.

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.

Features of the converter

4.1 Features of the converter

Power supply harmonics generated from the converter part of an inverter may affect devices including a dynamo and a static
capacitor. Power supply harmonics are different from noise and leakage currents in source, frequency band and transmission
path. By using a high power factor converter, power supply harmonics may be suppressed, allowing the compliance with the
harmonic suppression guideline issued by the former Japanese Ministry of International Trade and Industry (currently the
Ministry of Economy, Trade and Industry). The converter is classified as the self-excitation three-phase bridge circuit, and
achieves K5 (the conversion factor) = 0. (It is assumed that the converter generates no harmonics.)
NOTE
• Inverter parameters must be set. The parameter settings differ by the inverter series. Refer to page 23.

NOTE
• It does not mean that any harmonic components completely disappear.
• When the load is light, harmonic suppression effect declines.
• When the power supply voltage is unstable, power harmonics flow in, making the harmonic current increase.
• The power factor decreases when the setting of Pr.84 or Pr.85 is changed from the initial setting. (Refer to page 107.)

Harmonic suppression guidelines in Japan

4.2 Harmonic suppression guidelines in Japan

Harmonic currents flow from the inverter to a power receiving point via a power transformer. The Harmonic Suppression
Guidelines was established to protect other consumers from these outgoing harmonic currents.
All capacity and all models of general-purpose inverter used by specific consumers are now covered by "the Harmonic
Suppression Guidelines for Consumers Who Receive High Voltage or Special High Voltage" (hereinafter referred to as "the
Specific Consumer Guidelines").
• "Specific Consumer Guidelines"
This guideline sets forth the maximum harmonic currents outgoing from a high-voltage or especially high-voltage receiving
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.

• 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.

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.

Techniques and measures for electromagnetic compatibility (EMC)

4.3 Techniques and measures for
electromagnetic compatibility (EMC)
4.3.1 Countermeasures 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.

To install the earth leakage circuit breaker on the inverter circuit, select its rated sensitivity current as follows.
• Breaker designed for harmonic and surge suppression
Rated sensitivity current I∆n ≥ 10 × (Ig1 + Ign + Ig2 + Ig3 + Igm)
• Standard breaker
Rated sensitivity current I∆n ≥ 10 × {Ig1 + Ign + Ig2 + 3 × (Ig3 + Igm)}

NOTE
• Install the earth leakage circuit breaker (ELB) on the input side of the converter.
• In the connection earthed-neutral system, the sensitivity current is blunt against a ground fault in the inverter output side.
78
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)
• Do not install the breaker on the output side of the inverter. Doing so may cause unnecessarily operations by harmonics even
PRECAUTIONS FOR USE OF THE CONVERTER
if the effective value is within the rating, since the eddy current and hysteresis loss will increase, leading to temperature rise.
• The following models are standard breakers: BV-C1, BC-V, NVB, NV-L, NV-G2N, NV-G3NA, and NV-2F earth leakage relay
(except NV-ZHA) and the NV class earth leakage circuit breaker with AA neutral wire open-phase protection.
The other models are designed for harmonic and surge suppression: NV-C/NV-S/MN series, NV30-FA, NV50-FA, BV-C2,
earth leakage alarm breaker (NF-Z), NV-ZHA, and NV-H.

Set the integral gain for the voltage control. Increasing the setting value shortens the recovery time from the DC voltage fluctuation caused by external disturbance.
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
and Pr.23.
• The OL signal is output when output currents are limited by the current limit level (when the current limit function is active).

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.

 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.
