Hyundai N300 Inverter Drive.


Hyundai N300 Inverter Drive.

Powerful high torque performance has been accomplished using advanced sensorless vector control. Powerful operation is possible for two motors at the same time. Auto-tuning to perform sensorless vector control can now be easily done both on-line and off-line. Versatile functions encompass more applications. Field replacement of cooling fans and DC bus capacitors can be accomplished in a fraction of the time.

Features

Powerful Operation with Advanced Sensorless Vector Control

Powerful high torque performance has been accomplished using HHI's advanced sensorless vector control.

  • High starting torque of 200% or greater at 0.5 Hz
  • Rotational fluctuation at low speed has been drastically reduced to enhance process stability and precision.
  • High torque of 150% at approximately 0 Hz

    • High torque of 150% at approximately 0 Hz is accomplished when N300 drives a smaller motor by one frame size. Brake ON/OFF sequence can be easily integrated with this feature.

  • High torque multi-motor operation

    • Powerful operation is possible for two motors at the same time. In the case of conventional sensorless vector control, only one motor can be controlled. (Note : The two motors must be the same model and capacity)

  • On-line/off-line auto-tuning

    • Auto-tuning to perform sensorless vector control can now be easily done both on-line and off-line. On-line auto-tuning makes it possible for the motor characteristics to be updated automatically under "real time" ambient conditions.

Versatile Functions Encompass More Applications

  • Input / output function

    • Intelligent terminal system is applied to both input and output terminals. Sink/source type logic selection is possible.

    In addition to the pulse output monitor, analog (current and voltage) output terminals-AM and AMI are added as standard.

    An auxiliary speed input or "trim" can be made by an additional analog signal.

  • Third motor constants setting

    • Constants for up to three motors can be set. This function is useful for controlling (multiaxis) motors via changeover.

  • Deceleration and stop at power failure

    • N300 decelerates and stops the motor using regenerative energy from the motor even though the power is not supplied. Especially critical in some textile processes.

  • Fan ON/OFF selection

    • The cooling fan operates while the inverter is running, and stops when the inverter stops. This feature provides longer cooling fan life, and eliminates fan noise while the inverter is idle.

  • UP/DOWN function

    • Up/down function fine-tunes output frequency. Convenient for a test-run.

  • PID operation

    • Helps simplify the system and save initial cost no need for external PID controller. Useful for such applications as droop control.

  • Frequency scaling conversion

    • Display the output frequency scaled by the conversion factor for "line"/process speed.

  • 3-Wire function

    • "Seal-in" start signal without an external device.

  • P.PI control selection

    • Provides stable control for carrier or trolley (material handling) operations.

Easy Maintenance

  • Easy-removable cooling fan and DC bus capacitor

    • Field replacement of cooling fan(s) and DC bus capacitors can be accomplished in a fraction of the time.

  • Removable control circuit terminals

    • Eliminates control rewiring when replacing the N300.

Environmental Friendliness

  • EMI filter

    • EMI filters to meet European EMC and low voltage directives are available options for system conformance.

  • Reduced noise from control power supply

    • Noise terminal voltage of the control power supply has been improved by 20dB, resulting in significant reductions of noise interference with sensors and other peripheral devices.

Easy Operation

  • Digital operator

    • Standard digital operator (OPE-N3) is removable for remote control, and has easy-to-see 4-digit display and LEDs to indicate the unit being monitored.

  • User selection of command functions ("Quick Menu")

    • Frequently used commands can be selected and stored for quick reference.

  • Built-in RS485

    • RS485 is provided as standard for ASCII serial communication.

  • Programming software

    • Optional PC drive configuration software which runs on Windows® operating system.

Protection for Various Installation Environments

  • Standard enclosure protection for N300 is IP20 (NEMA1) (IP00 : 75~ 132 kW).

    • Global Performance

  • Network compatibility

    • N300 can communicate with DeviceNet, PROFIBUS and LONWORKS as options.
