Features
Smooth operation, precise control and powerful functionality

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.

Features

* 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.

Any type of machine starts smoothly at low speeds

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.

Precise control over a wide speed range

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

Four controls in one device; the ultimate device for all applications

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
