EM600 High-Performance Vector Drive
Product Introduction
The EM600 series high-performance vector-type general-purpose inverter is a 
new product developed by Ouhua Drives. Based on customer suggestions and needs, 
it has improved the product's ease of use and stability, and is also superior in 
motor control performance.
1) Rich voltage levels
Supports six voltage levels: single-phase 220V, three-phase 220V, three-phase 
380V, three-phase 480V, three-phase 690V, and three-phase 1140V .
2 ) Supported motor types
Supports vector control of three-phase AC asynchronous motors.
3 ) Rich control methods
Torque control, speed sensorless vector control, V /F control.
4 ) Speed ​​sensorless vector control 
algorithm
Speed ​​sensorless vector control (SVC) 
brings better low-speed stability, stronger low-frequency load capacity, and 
supports SVC torque control.
5 ) The feature-rich EM600 series vector inverter has the following 
outstanding features:
EM600 Highlights  | describe    | 
Dual display  keyboard  |     The entire EM600   series supports  dual-line LED display, and users can    customize the function parameters to be displayed.  
  | 
Backup and restore  user parameters  |     This function  supports customers to save or  restore their own set    parameters
  | 
User customized parameter  display  |     Users can customize a single row of  LEDs to display multiple   parameters  of the inverter's running and shutdown status.  
  | 
    User -changed  parameter display
  |     Users can  view the modified function  parameters
  | 
High-speed pulse input and  output  |     Supports high-speed  pulse input and output of 0~50.00HZ .    
  | 
Over-torque detection  protection  | Users can set the  over-torque   detection protection time and protection  threshold.  | 
Control settings for  multiple   acceleration and deceleration times    | Four groups of  acceleration and   deceleration time control can be set through terminals and  keyboard.  | 
Switch input and output    corresponding delay  | The user can independently  set the   response delay time of the switch input and  output.  | 
Restore user  parameters  | This function allows  customers to   save or restore their own parameters.    | 
Stable and reliable  overvoltage   stall protection  |     During the deceleration  process, the inverter protects the machine from   tripping due to a fault caused  by excessive bus voltage.
  | 
    PID parameter switching  
  |     It has two sets of PID parameters, which can be switched through   terminals or  automatically according to deviation.
  | 
    Use the up and down keys on the keyboard to set  the PID given    value
  |     The up and down keys on the keyboard can be used to  quickly set the   PID given  value without entering the parameters.  
  | 
The inverter can be used  as a   communication host. Without the need for a  host   computer, Multiple inverters can be  linked  |     In some cases, multiple  inverters need to run synchronously. In this   case, the frequency source commands  of multiple inverters are set as   communication settings. This can be achieved by  simply setting the   first inverter as the master and the others as slaves. This  ensures   that the set frequencies of multiple inverters are completely consistent    or in the same ratio.
  | 
Accurate speed  tracking  | After adapting the  corresponding   speed detection card, accurate speed tracking can be  achieved.  | 
Instantaneous stop without  stopping   (applicable to gas stoves Fans and other important  occasions)  |     The inverter automatically operates  when the voltage returns to   normal after  a momentary power outage , a    sudden drop in voltage due to mains and  generator conversion,   etc.
  | 
Automatic energy-saving  operation  | Automatic energy-saving  operation   can be achieved when light loads such as fans are  used  | 
Fast current  limiting  |     Avoid  frequent overcurrent faults of the  inverter and have super   strong load capacity.
