Compact Design


 
Front-access Maintenance        Low-noise Fan
 
   
The rack-in type is constructed with a simplified cell,allowing users to
access the drive from the front for maintenance. This eliminates need for
additional space in the rear reducing the product installation footprint.
     M1000A product uses a fan that has a drastically reduced noise level,
     supporting 0~10V speed control through its built-in PID control.
 


 
Improved Input Power Quality and THD (Total Harmonic Distortion) by Adopting Multi-winding Phase-shift Transformer
 
Application of extended delta-type transformer and
separated-type 
multi-pulse rectifier drastically reduces
input power THD, hence complying with IEEE-519 standard.

Input current almost identical to sine waves eliminates
need for additional 
harmonic filters or active filters on the
input side.
                                                                                                          



 
Producing Multilevel PWM-type Sinusoidal Output
 
Compatible with conventional motors
and cables to ensure it fits in with
existing system design


Minimal impact of voltage reflection,
allowing longer cable length between
drive and motor


Medium voltage drives minimize
mechanical stress on motor,
eliminating need for additional sine
wave filters.                                                               
                                                                                                       
                                                                                                               

 



Energy saving

 
Achieving Energy Saving and Minimum Energy Loss through Optimized Speed Control
 
 


Example of Operating Conditions

(1) Motor in use: 3300V, 600kW, 6P (Motor efficiency: 95%)
(2) Operating at 60% of air flow volume (Motor efficiency of 90% at 100% of flow volume)

Fan According to Heat Release
MY System View(Option)


 
● MV System View is a PC (Windows XP and Window 7 -
  compatible)-based software that uses RS485/232
  communication links between MVD and PC to control/
  monitor MVD.
● Communication standards and a built-in system view
  enables flexible application in various systems.
  It facilitates remote operation and operating state monitoring
  by higher-level systems.

Function
Cell Bypass Function

Automatically bypass of failed cells if cells connected in series randomly fail during operation, allowing continuous operation.




Flying Start
   
Automatically estimates speed of the rotating
motor to reach the frequency without any system
failure(trip)
























 
 



 
Ride-through Capability
 
Mechanical energy of load is regenerated to continue operation for up to 5 cycles when power outage occurs. It allows
continuous operation without stopping the drive or system.



Anti-current Hunt Algorithm in Resonance Area
 
Continuous drive operation possible in the resonant area followed by application of the drive

 


Sensorless Vector Function

Improved Starting Torque and Accurate Torque Control
Powerful sensorless algorithm improves speed and torque control precision in low-speed area

 



Synchronous Transfer Function

•Switching motor power from medium voltage drive to commercial power (bypass mode) or vice versa (drive mode)
•Synchronous transfer function performs synchronization of the phases of two power sources while motor is running,
 enabling power transfer and prevention of ensuing over-current


Design
Power Cell

•Cell-specific keypad allows users to check individual cell details
•Additional R/S/T and P/N check PIN allows for safe cell state monitoring



Cascaded H-bridge Multi-level Drive

•Adopting multi-winding phase-shift transformer lowers input THD (Eliminating the need for input filters)
•Multiple voltage steps allow lower output THD (Eliminating the need for output filters)
•Reducing common mode voltage and leakage current (Effective to extend motor service life)
•Enabling complete modularization of power module circuits
•Modular design makes easy voltage increase
•Continuous operation possible through individual power cell failure
•Minimal impact of voltage reflection allows for longer cable distance between drive and motor
