Greatly suppressed power supply harmonics

The HC2 converters, being the self-excitation three-phase bridge circuit under "the Harmonic Suppression Guidelines for

Specific Consumers", take the conversion coefficient of the equivalent capacity (K5 = 0).

PWM converter

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 smaller equipment saves the cost of equipment.

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.

Connectable to multiple inverters

Inverter

The common converter method enables the connection to up to

10 inverters.

The power returned during regenerative driving can be supplied to another inverter, saving the overall energy.

Compact 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).

Long life parts and life diagnosis function

(1) Longer life parts

The service life of the cooling fans is now 10 years

*1

and that can be even longer with the ON/OFF control of the cooling fan.

Capacitors with a design life of 10 years *1*2 are adapted.

(Using a surrounding air temperature of 105˚C for 5000 hours). With these capacitors, the service life of the converter is further extended.

*1 : Surrounding air temperature: Annual average of 40ºC (free from corrosive gas, flammable gas, oil mist, dust and dirt).

The design life is a calculated value and is not a guaranteed product life.

*2 : Input current: 80% of the high power factor converter rating

(2) The leading-edge life diagnosis function

The degree of deterioration of the main circuit capacitor, cooling fan, and inrush current limit circuit can be diagnosed on the monitor.

Using the self-diagnosis function, the part life warning can be output and the deterioration degree can be monitored. Thus, the self-diagnosis function prevents troubles from occurring.

*4 : A warning is output when any of the control circuit capacitor, inrush current limit circuit, and cooling fan reaches its output level.

Operation panel equipped with the setting dial

(FR-DU07-CNV)

7

Supporting more network protocols

Parameters can be copied using the operation panel

(FR-DU07-CNV).

The setting values of the parameters can be stored to the operation panel and the option parameter unit (FR-PU07).

Items such as input current, input voltage, input power (with the regenerative display), bus voltage, etc. can be monitored.

Operation can be easily performed with the setting dial.

HC2 supports RS-485 as a standard. With the option

FR-A7NC, HC2 also supports CC-Link.

•The power can be monitored during driving/regenerative driving, and this monitoring tells you the energy saving effect.

•Alarm functions and voltage monitors of each phase help you to spot the cause of the alarm.

: Available model −: Not available

Compatible with UL, cUL, EC Directives (CE marking) as standard.

Compliant with the RoHS Directive. Friendly to people and to the environment.

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.
