EI-Super N is a general-purpose inverter with flux vector control. It directly controls the current or torque in an AC induction motor. EI-Super N is suitable for a wide variety of applications.

EI-Super N provides smooth start-up at low speeds (1% of rated speed) and precise operation. Its auto-tuning function enables high performance tuning of all induction motors.

EI-Super N combines four control methods:

• open loop vector
• flux vector
• V/F control with PG feedback
• V/F control

From precision machinery to multiple motor drives, EI-Super N proves to be the ultimate drive for all applications.

• 32bit DSP microprocessor configuration
• magnetic field oriented flux vector control
• auto-tune ability
• available for speed-type servo controller while PG feedback added
• RS-232/RS-485 serial communication port
• RS232/TCP-IP interface card
• capacities from 1HP - 400 HP
• optional DC reactor available (for reducing harmonic interference from the power supply)
• multi-language large screen LCD displays the drive status in six languages and a parameter copy mode function.
  • English
  • Chinese
  • Russian
  • German
  • French
  • Spanish

EI-Super N features full-scale flux vectore current control that directly controls motor torque based on present control theory utilising a magnetic flux observer and neuro-control.

It features full torque control even at zero speed when PG option is added.

EI-Super N features highly precise operation throughout the motor's entire speed range, even under fluctuating load conditions.

Four control methods are included:

• Standard V/F control
• V/F control with PG feedback
• Sensorless flux vector control
• Flux vector current control with PG feedback

Simply select the parameters, EI-Super N can be applied to a wide range of applications from servo-like precision machinery to multiple motor drives.

Factory presets default to sensorless vector control type, but it can be configured to the V/F control mode for applications requiring multiple motors on one device, or set to flux vector current control mode (with PG) for hughly precise vector operation. (PG-B interface card is optional)

Note: at low speed, high torque and continuous operation, a forced cooling special motor must be used
