Hyundai N700V Inverter Drive.


Hyundai N700V Inverter Drive.

The Hyundai N700 series Inverter can be applied to various loads requiring precision and powerful control thanks to its excellent durability, speed and torque response. Strong torque restriction function protects the machines from external torque changes. The N700 series is compliant with RoHS directive and international safety standards such as CE, UL and cUL.

Features

    Improved Control Performance

    Advanced Sensorless Vector Control at Ultra Low Speed

    Excellent control performance with all machines thanks to the improvement of torque characteristics at low speeds.

  • Sensorless vector control :200% or greater at 0.5Hz
  • Sensored vector control :150% or greater at 0Hz

    • Excellent Response Speeds and Toque Control Performance

  • Improvement of the torque response characteristic minimizes the speed deviation when the load is changed. (Quick response to a sudden load change is realized.)
  • Strong torque restriction function (adjustable 0~200%) can protect the machine from external unexpected load changes.
  • Minimize the response speed regarding the terminal command.

    • Improvement of Reduced Torque Characteristic

  • Reduced torque characteristic (VP2.0 power) is added for softer motor operation.
  • Optimization for energy saving by the characteristic of loads is achieved.

    • Expansion of Multi-speed Control Function

  • Besides the basic accel.-decel. time, a maximum of 7 individual accel.-decel. time settings are available. With terminal input only, you can change the accel-deceleration time, which gives more precise control.
  • Three step accel.-decel. time setting is possible.

    • Stable and Strong Torque Operation

  • As users may select either speed control or torque control at their convenience, they can apply N700 inverters to various applications (Vector Control).

    • Expansion in The Field Weakening Operation Range

  • The field weakening operation range where the maximum torque operation can be made is extended to 320Hz.

    • Advanced Online, Offline Auto-tuning

  • Online and offline auto-tuning for sensorless control
  • Even in case of offline auto-tuning, the characteristic of the torque and speed control is excellent. (Regardless of the load conditions, auto-tuning can be performed)
  • In case of online auto-tuning, precise operation can be realized through the automatic compensation for motor constant method even when the motor's temperature changes.

    • Improved DC Brake Function

  • Improved brake characteristic at stop command by upgrading the DC brake function.

    • External Brake Control Function for Elevator

  • By using the external brake for the elevator application, safe and detailed control on all the variables is realized. The operating speed can be changed according to the load.

    • High Quality Voltage and Current

  • Even if the incoming voltage fluctuates, the AVR function keeps the output voltage constant to the motor.
  • The 'Trip Avoidance Function' to control the over-current and over-voltage helps supply the high quality of power source to the motor.

    • Automatic Speed Search after Unexpected Interruption of Input Power

  • The inverter and motor can be safely restarted or protected by FRS and RETRY function.
  • Variable speed search restart mode can be selected for safe driving.
  • By using the frequency matching restart and speed search function, the inverter can match the motor�s speed after unexpected power failure.

    • IGBT Temperature Check

  • The temperature of IGBT (core part of inverter) is checked and displayed.

    • Easy Operation and Maintenance

    Various Inverter Display Functions

    All the data of the inverter are displayed on the monitor.

  • The trip data of each phase are displayed in case of input phase loss and output short
  • Temperature on the IGBT
  • Others (In-Out voltage, current, frequency, DC voltage, input power, RPM of motor, rotation direction, frequency change, PID Feedback, accumulated operating time (hour, minute), total power up time (hour, minute), error and trip count display)

    • RUN(0,1,2) Relay Control Terminal Added

  • Run output terminals (RN0,1,2) are added for user's convenience

    • 12 User Group Codes

  • Users can save the preferred codes (Max. 12) for fast and easy operation and set or adjust data in accordance with the characteristics of the loads.

    • Convenient Operation

    Operator

  • Large LED and convenient settings (code/parameter)
  • Noise resistant design (Max. 10m cable)

    • OPE-N7 (standard) has parameter copy function.

    Maintenance

  • Detachable cooling fan and independent DC bus capacitor make replacement and maintenance easy and simple
  • Adoption of detachable control circuit terminals
