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.
