Power regeneration function for energy saving
The power regeneration function, which comes as a standard
feature, eliminates the need for brake units. The power
regeneration function gives a great breaking capability.
(Regeneration is available continuously with 100% torque,
and for 60s with the maximum of 150% torque.)
The regenerative power from the motor is returned to the
power source, and such a system significantly saves energy.
3Connectable to multiple inverters
The common converter method
enables the connection to up to
10 inverters.*1
The power returned during
regenerative driving can be
supplied to another inverter,
saving the overall energy.
*1 : Be sure to use a high power factor converter with
the capacity higher than the total capacity of the
inverters or the total capacity of the motors.
(Refer to page 12.)
4Compact design for space saving
The high power factor converters (excluding 15K) and input
reactors (75K or higher) have become much smaller than their
conventional models (FR-HC, MT-HC).

To obtain higher environmental resistance, the FR-HC2 has coated printed circuit boards
and copper plated conductors. Magnetic contactors also have anti-corrosive coatings on.
The coated printed circuit board model (FR-HC-K-60) of the conventional series is
replaceable with the standard model of this series.
[Note]
•These coating treatments do not guarantee an operation environment beyond the
range indicated in the product specification.
•Coating is applied to the printed circuit board areas excluding its LEDs, connectors,
terminal blocks and their peripherals, where coating cannot be applied.
•As for the anti-corrosive treatment of the magnetic contactor, plating is applied to
the copper areas where no surface treatment is applied.

The waveform with high peaks, which is typical of
inverter's input current, is reshaped to be a sine
wave with lower input current effective values.
The lowered effective value enables adoption of
smaller power-supply-side devices, such as a
power supply transformer, MCCB, and cables. Such

The required converter capacity differs by the multiple rating selection setting of the inverter.
Refer to the following table for the connectable inverter capacities when connecting one inverter to a high power factor
converter. (Other combinations are not applicable.)
: Compatible
—: The converter can be used as a common converter or a regenerative converter, but its harmonic suppression effect
reduces.
: Not compatible (Not applicable)
When the inverter capacity and the applicable motor capacity are equal (FR-A800 (ND rating), FR-F800
(LD rating), and 700 series inverters)
When the applicable motor capacity is higher than the inverter capacity (FR-A800 (LD rating), FR-A800
(SLD rating), and FR-F800 (SLD rating))
Compare the high power factor converter capacity chosen based on the table above and the applicable motor capacity. Then,
choose the high power factor converter according to the capacity whichever is higher.

Up to ten inverters can be connected to one converter. Be sure to use a high power factor 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 high power factor converter. (High power factor converter capacity × 1/2 ≤total
capacity of connected inverters or motors ≤high power factor converter capacity)
If the total inverter capacity is less than half the capacity of the high power factor converter, the converter can be used as a
common converter or a regenerative converter. However, its harmonic suppression effect is reduced.
(1) Junction terminals or cross wiring are used to connect several inverters, so carefully select the wire gauge. Start adding
the inverter capacities from the furthest inverter.
(2) When connecting several inverters, connect starting with the inverter with the highest capacity.
(3) Installation of a fuse, which corresponds with each motor capacity, is recommended for each inverter when connecting
several inverters to one converter. Select a fuse according to the motor capacity.
When using a motor, of which capacity is smaller than the inverter capacity by two ranks or more, select the converter
capacity according to the inverter capacity. (Refer to page 28)
(4) Keep the total wiring length within 50m.
Main circuit wiring example
The following diagram shows a connection example of the FR-HCL-55K to six inverters: the FR-A820-01540(30K),
00770(15K), 00340(5.5K), 00167(2.2K), 00105(1.5K), and 00070(0.75K) (54.95 kW capacity in total).

When installing a converter inside an enclosure, the heat generated in the enclosure can be greatly reduced by protruding the
heatsink of the converter.
This installation method is recommended when downsizing the enclosure and such.
When using a heatsink protrusion attachment (FR-A7CN)
For the FR-HC2-7.5K to 75K and FR-HC2-H7.5K to H110K, a heatsink can be protruded outside the enclosure using a
heatsink protrusion attachment (FR-A7CN). (For the 160K or higher, the attachment is not necessary when the heatsink is to
be protruded.)
Refer to the table below for the applicable heatsink protrusion attachments.
(For the details of FR-A7CN, refer to the Instruction Manual of the option FR-A7CN.)
(1) Heatsink protrusion attachments
For a combination other than above, please contact your sales representative.

 Do not insert MCCB between terminals P/+ and N/- (P and P, N and N).
 Always connect the terminal R, S, and T of the converter to the power supply. If the inverter is operated without connecting the terminals to the power supply,
the converter will be damaged.
 Do not insert MCCB or MC between (1) (terminal R/L1, S/L2, T/L3 input of the converter) and (2) (terminal R4/L14, S4/L24, T4/L34 input of the converter) of
the above diagram. It will not operate properly (except for the inrush current limit MC).
 Securely perform grounding (earthing) by using the grounding (earthing) terminal.
 Installation of a fuse is recommended. (Refer to page 28)
 The number of filter capacitors and filter capacitor alarm detectors differs by the capacity. Connect two sets of filter capacitors and filter capacitor alarm
detectors for H400K, and connect three sets for H560K.
NOTE
• When connecting the converter to the inverter, match the control logic (sink logic (initial setting)/source logic). The
converter does not operate properly if the control logic is different.
(Refer to the Instruction Manual for the switching of the control logic. Refer to the Inverter Instruction Manual for the
switching of the control logic of the inverter.)
• Keep the wiring length between terminals as short as possible.
• When sudden large distortion or depression of power supply occurs, reactor may generate abnormal acoustic noise.
This acoustic noise is caused by the power supply fault and not by the damage of the converter.
• Do not connect the DC reactor to the inverter when using a high power factor converter.
• When using a sine wave filter with FR-HC2 (75K or higher), select MT-BSL-HC as a reactor for the sine wave filter.
