    The 3G3MV is OMRON’s first compact Inverter incorporating an open-loop vector control function, which ensures a torque output that is 150% of the rated motor torque at an output frequency of 1 Hz. Ensures a more powerful revolution at low frequencies than any conventional inverter. Furthermore, the 3G3MV Inverter suppresses the revolution fluctuation caused by the load.

    • Multi-function analog output or pulse train output is selectable as monitor output H Suppression of Harmonics Connects to DC reactors, thus suppressing harmonics more effectively than conventional AC reactors. Further improvement in the suppression of harmonics is possible with the combined use of the DC and AC reactors.

    An Inverter overheating warning input has been added as a new function that can be set for multi-func- tion inputs 1 to 7 (n050 to n056). When this warning is input, an oH3 fault (nonfatal error) will be dis- played. This input can be used for functions such as thermal contact connections for peripheral over- heating detection.

  • Page 28

    Parameter n081 can be set so that operation will not restart after a power interruption until the RUN signal is ON for the time specified for the parameter (5 to 100 x 0.1 s). If the parameter is set to 2 (Inverter restarts when power is restored), operation will recover for all Inverters at the same time, meaning the power supply capacity must be sufficient for the maximum current.

    • Do not install the Inverter on inflammable material such as wood. • If a 5.5- to 7.5-kW Inverter or a C-type Inverter is to be installed inside of a control panel, it must have the top and bottom covers removed and be used as a panel-mounting model (conforming to IP00).

  • Page 35

    • To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature changes. • If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50°C.

    Design D Installing a Magnetic Contactor If the power supply of the main circuit is to be shut off because of the sequence, a magnetic contactor can be used instead of a molded-case circuit breaker. When a magnetic contactor is installed on the primary side of the main circuit to stop a load forcibly, however, the regenerative braking does not work and the load coasts to a stop.

    The Inverter’s outputs utilize high-speed switching, so noise may be transmitted from the Inverter to the power line and adversely affect other devices in the vicinity. It is recommended that a Noise Filter be installed at the Power Supply to minimize this noise transmission. Conversely, noise can also be re- duced from the power line to the Inverter.

If the cable must be longer than 100 meters, take measures to reduce the floating capacity by not wiring in metallic ducts, by using a separate cable for each phase, and so on.

    H Ground Wiring • Always use the ground terminal of the 200-V Inverter with a ground resistance of 100 Ω or less. Simi- larly, always use the ground terminal of the 400-V Inverter with a ground resistance of 10 Ω or less.

    Third harmonic (180 Hz) Problems Caused by Harmonics Generation The waveform of the commercial power supply will be distorted if the commercial power supply contains excessive harmonics. Machines with such a commercial power supply will malfunction or generate excessive heat.

  • Page 59

    The Inverter as well as normal electric machines has an input current containing harmonics because the Inverter converts AC into DC. The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine. Voltage...

    The DC reactor suppresses harmonics better than the AC reactor. The DC reactor used with the AC reactor suppresses harmonics more effectively. The input power factor of the Inverter is improved by suppressing the harmonics of the input current of the Inverter.

    Motor vibration may, however, become greater in the following cases. • Resonance with the natural frequency of the mechanical system Take special care when a machine that has been operated at a constant speed is to be operated in variable speed mode.

    The speed range for continuous operation differs according to the lubrication method and motor manufacturer. In particular, the continuous operation of an oil-lubricated motor in the low speed range may result in burning. If the motor is to be operated at a speed higher than 60 Hz, consult with the manufacturer.

  • Page 331

    Surge occurs among the phases of the motor when the output voltage is switched. If the dielectric strength of each phase of the motor is insufficient, the motor may burn out. The dielectric strength of each phase of the motor must be higher than the maximum surge voltage.
