Features

Harmonic

mode

The FR-XC-(H)15K or lower does not have the harmonic suppression function.

FR-XC

FR-XCB

Harmonic suppression (K5 = 0) achieved• The FR-XC series converter is classified as the self-excitation three-phase bridge circuit under the "Harmonic Suppression Guidelines
for Specific Consumers" and achieves K5 = 0 (conversion factor for equivalent capacity) when its harmonic suppression function isenabled and in use with the dedicated box-type reactor FR-XCB. (It is assumed that the converter generates no harmonics.)
The total harmonic distortion of the input current (THDi) is 5% or less*1, which facilitates compliance with the overseas
standards related to harmonic suppression.
*1 When the input voltage is distorted, harmonic contents increase because power harmonics flow into the FR-XC series converter.

• The waveform with high peaks, which is typical of the input current to the inverter section from the converter section in
an inverter unit, is rounded to make a sine wave with a lower input current effective value.

Power supply capacity reduced by power factor improvement• With the reduced effective value of the input current to the inverter section, it is possible to install a power transformer,
MCCB, cables, etc. with smaller capacity on the converter input side to reduce the equipment cost.

Wire and space saving
The slim converter requires less space, and the FR-XCB
box-type reactor*2 enables wiring reduction as it contains
peripheral devices such as reactors.

Conventional model*2 Used for the FR-XC converter in harmonic suppression mode.

Space saving by increasing the current rating
When the 40°C rating of surrounding air temperature isselected within the temperature derating range, the current
rating and the current to be applied can be increased.
When the FR-XC series converter is intended for the use at
the surrounding air temperatures less than 40°C, a modelwith a smaller capacity is applicable. With smaller converter,
less space is required.

Power regeneration contributing to energy saving
Power regeneration
Regenerative energy

Power supply

One of the two regeneration modes can be selected depending on the application.

Regeneration
converter

Using regenerative power can increase power efficiency and reduce the CO2
emission (power consumption) of the equipment. This creates the new added
value of contributing to carbon neutrality.

Commonbus regeneration
mode

Features

While the motor rotates to drive the machine during power driving, the machinerotates the motor during regenerative driving, which results in energy saving since
the motor serves as a generator which returns the power to the power supply.
For example, when a power of 70 kW is required for power driving and a power of 30
kW is required for regenerative driving, the power consumption is reduced by 30%.

FR-XCBThe FR-XC series converter can connect to up to 10 inverters*3
together, though its predecessor FR-CV series converter is designed
to connect to up to 6 inverters.
The power returned from an inverter during regenerative driving can besupplied to another inverter, saving the overall energy.
None of the inverters requires a brake unit, which enables total spaceand cost reduction.

FR-XC

FR-XCGSpace saving achievable depending on the regenerative power
For power driving, the inverter supplies power. For regenerative
driving, the FR-XC series converter returns power to the power
supply. (In this mode, the FR-XC series converter cannot be
used as a common converter.)
The capacity of the FR-XC series converter is selectableaccording to the regenerative power of the system. Thus, thecompact converter is applicable for the regenerative powersmaller than the inverter capacity, which contributes to spacesaving. (Refer to page 64 for selection.)
For example, if you use the 30 kW inverter and the regenerative
power of your system is 5.5 kilowatts, you can choose the 7.5
kW converter instead of the 30 kW converter.
The converter with its harmonic suppression function disabled
can be used in the power regeneration mode.

Network compatibility

Large braking force

RS-485 communication is supported as standard. With
the FR-A8NC communication option, the converter also
supports CC-Link communication.
• As power can be monitored during both power driving
and regenerative driving, the energy saving effect can bechecked any time.
• Monitoring of faults and the voltage of each phase allows
you to analyze the fault cause easily.

The power regeneration function (enabled continuouslywith 100%*1 torque or for 60 seconds with the maximum
torque of 150%) offers a large braking force, eliminating
the need for brake units.

 Protruding the heat sink through a panel
When encasing the multifunction regeneration converter in an enclosure, the heat generated in the enclosure can be greatly reduced
by exposing the heat sink of the converter. (The 30K converters or lower are designed to be installed in an enclosure with its heat sinkprotruded through the panel of the enclosure.)
This installation method is recommended when installing the converter in a compact enclosure.

[30K converters or lower]
Refer to page 17 for instructions on cutting the panel of the enclosure.

NOTE• Use the FR-XCCP (converter installation attachment for enclosure) to install the 30K converter or lower in the enclosure.

To avoid interference with the cooling fan on top of the heat sink, thethickness of the panel of the enclosure should not exceed 10 mm andthe space around the fan should be cleared.

NOTE• As the heat sink section protruded through the panel includes a cooling fan, this type of installation is not suitable for environment inwhich the converter may be exposed to drops of water, oil mist, dust, etc.
• Make sure that screws, debris etc. do not get into the converter and cooling fan.

 Operating condition• To select the converter, refer to page 62 for the potential regenerative capacity and overload current rating of the converter. Ensurethat the selected converter is one with a larger regenerative power than that of the motor that will be used.
• Confirm that the converter is correctly selected, and select a dedicated stand-alone reactor (FR-XCG) by referring to "Combination
matrix of FR-XCG and FR-XC(-PWM)" on page 13.
Selection example:
For the 50°C rating
For a motor which can supply 10 kW regenerative power with an overload capacity of 120% (12 kW) for 60 seconds, the FR-XC15K (15 kW converter) should be selected.

Connect between the inverter terminal P/+ and the converter terminal P4 and between the inverter terminal N/- and the converter terminal N/- for polarity consistency.
Connecting the opposite polarity of terminals P/+ and N/- will damage the converter and the inverter.
Confirm the correct phase sequence of three-phase current to connect between the reactor and the converter, and between the power supply andthe reactor.
Incorrect connection will damage the converter.
Always connect between the power supply and terminals R/L1, S/L2, and T/L3 of the converter. Operating the inverter without connecting them will
damage the converter. A branch point to each of these terminals must be placed between the power supply and the FR-HAL reactor.
Install the FR-XCG reactor between the power supply and the converter as shown in the figure. For information to select an appropriate model,
refer to page 13.
To connect a DC reactor, remove a jumper installed across terminals P1 and P/+ before installing the DC reactor.
When using a separate power supply for the control circuit, remove the jumpers connected to terminals R1/L11 and S1/L21.
For selection of an MCCB for the converter, refer to page 70.
Install the UL listed fuse (refer to the FR-XC Instruction Manual) on the input side of the FR-XCG reactor to meet the UL/cUL standards.
Do not install an MCCB or MC between the reactors and the converter. Doing so disrupts proper operation.

• Dedicated reactor installed between power supply and the FR-XC series converter:
The terminals R/L1, S/L2, and T/L3 on the converter are control terminals to detect power phases of the power supply. For wiring,
the voltage phase must be consistent between terminals R2/L12, S2/L22, and T2/L32 and terminals R/L1, S/L2, and T/L3. If theseterminals are not connected correctly, the converter does not operate properly.
If the inverter is operated while the converter terminals R/L1, S/L2, and T/L3 are not connected to the power supply, the converter
will be damaged.
• In the common bus regeneration mode, always connect between the converter terminal RYB and the inverter terminal to which theX10 (MRS) signal is assigned, and also connect between the converter terminal SE and the inverter terminal SD. If the terminals
are not connected, the converter may be damaged.
• For use of the FR-XC series converter in the common bus regeneration mode, the control logic (sink/source) of the converter andthe inverter must be matched. The converter does not operate properly if the control logic is not consistent with each other. (Referto the Instruction Manual of the converter/inverter for the switching of the control logic of the converter/inverter.)• For use of the FR-XC series converter in the common bus regeneration mode, keep the wiring length between terminals as short as
possible.

 Precautions for use• Since the FR-XC series converter in harmonic suppression mode achieves K5 (the conversion factor) = 0, it is assumed by the
Harmonic suppression guidelines that the converter generates no harmonics. However, it does not mean that harmoniccomponents completely disappear.
• To maintain the security (confidentiality, integrity, and availability) of the drive unit and the system against unauthorized access,
DoS attacks, computer viruses, and other cyberattacks from external devices via network, take appropriate measures such as
firewalls, virtual private networks (VPNs), and antivirus solutions.
We shall have no responsibility or liability for any problems involving drive unit trouble and system trouble by DoS attacks,
unauthorized access, computer viruses, and other cyberattacks.


DoS: A denial-of-service (DoS) attack disrupts services by overloading systems or exploiting vulnerabilities, resulting in a denial-of-service (DoS)
state.

Precautions on Selection and Operation

 Precautions when selecting the inverter and reactor• Applicable Inverter:
Prepare an inverter that is compatible with DC input.
For the MELTRAC series inverters and FR-A500L/F500L series inverters, make sure that an inverter to be applied is compatible
with the FR-XC series converter. Use of the FR-XC series converter with an incompatible inverter will damage the inverter and theconverter.
• Dedicated reactor:
Use the FR-XC series converter in combination with the dedicated stand-alone reactor (FR-XCL or FR-XCG) or the dedicated boxtype reactor (FR-XCB).
The combination depends on the connection mode.
Common bus regeneration mode: FR-XCL
Harmonic suppression mode: FR-XCB
Power regeneration mode 2: FR-XCG

 Precautions on peripheral device selection• Selection and installation of molded case circuit breaker
Install a molded case circuit breaker (MCCB) on the input side of the FR-XC series converter to protect the wiring on that side. For
selection of the MCCB, refer to the following pages: page 42 (common bus regeneration mode), page 56 (harmonic suppressionmode), page 70 (power regeneration mode 2). (Check the documents related to the applicable breaker.) As an earth leakage
current breaker, use the Mitsubishi Electric earth leakage current breaker designed for harmonics and surge suppression.
• EMI measures
The FR-XC series converter can generate electromagnetic noises. In a system including the converter in harmonic suppressionmode, 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.
The FR-BIF radio noise filter is useful for suppressing noise on AM radio broadcasting.
The FR-BSF01/FR-BLF line noise filter is useful for preventing malfunction of sensors, etc.
As precautions against the induced noise emitted from power cables of the converter and inverter, it is preferable to keep a distanceof 30 cm or more between the sensor circuit and noise sources such as the converter, the inverter, and their power cables.
However if this is not possible, keep a distance of at least 10 cm. Use shielded twisted pair cable for signal cables of the sensor. Do
not earth (ground) the shield, and connect the shield to the signal common terminal.

Decrease the carrier frequency.

Do not connect earthing (grounding) cables of the sensor directly to the enclosure.
Do not use control cables for earthing (grounding).

 Others• It is not a fault if noise comes from the dedicated reactor during regenerative driving of the converter (in other words, it is a fault if
noise comes despite the stop state of the converter by the Converter stop (SOF) signal).
If needed, devise methods of reducing noise by modifying the enclosure in which the reactor is installed.
