EM Series Frequency Converter Overview

EM Series Frequency Converter Overview

Product Introduction

1) Comprehensive Voltage Ratings

Supports six voltage levels: single-phase 220V, three-phase 220V, three-phase 380V, three-phase 480V, three-phase 690V, and three-phase 1140V.

2) Extensive Motor Type Support

Supports vector control for three-phase AC induction motors and three-phase AC permanent magnet synchronous motors.

3) Diverse Control Modes

In addition to sensor-based vector control, sensorless vector control, and V/F control, it also supports V/F split control.

4) Wide Range of Encoder Types

Supports differential encoders, open-collector encoders, and more.

5) Sensorless Vector Control Algorithm

Sensorless Vector Control (SVC) delivers superior low-speed stability, enhanced low-frequency load capacity, and supports SVC torque control.

6) Powerful External Expansion Cards

Multi-function IO input card, RS485 communication card, injection molding machine card, feeder card, motor overheat card, water supply triple-drive expansion card, etc.

7) The feature-rich EM590 series vector inverters excel in the following functionalities:

8) Parameter upload/download: Keyboard-based parameter transfer enables effortless batch debugging.

9) User parameter backup/restore: Allows customers to independently save or restore custom settings.

10) Modified parameter display: Users can view altered functional parameters.

11) Custom parameter display: Users may configure required functional parameters for display.

12) Chinese Keyboard: The entire EM590 series supports Chinese keyboard operation, enabling use without a manual.

13) Intuitive PID Water Supply Pressure Setting: During PID water supply, the setpoint is no longer calculated as a percentage multiplied by the pressure gauge range. Instead, the target pressure is directly set in megapascals (MPa), eliminating calculations and enhancing intuitiveness.

14) Keypad Knob for Quick PID Setpoint Adjustment: After defining the keypad numeric knob for PID setpoint adjustment, users can directly set the PID setpoint via the knob without entering parameter menus. Resolution reaches 0.01 MPa.

15) Inverter as Communication Host: Enables multi-inverter synchronization without a host computer. When multiple inverters require synchronized operation, set their frequency source commands to communication mode. Designate one inverter as the host and others as slaves to ensure identical or proportionally consistent frequencies across all units.

16) Precise speed tracking: When equipped with the corresponding speed detection card, accurate speed tracking is achievable.

17) Instantaneous power loss recovery (essential for critical applications like gas furnace fans): Following an instantaneous power outage, utility-to-generator switching, or sudden voltage dip, the drive automatically resumes operation upon voltage restoration (requires corresponding expansion card).

18) Automatic Energy-Saving Operation: Enables automatic energy-saving operation when driving light loads such as fans.

19) Motor Overheat Protection: With the motor overheat expansion card, the V3 can receive motor temperature sensor inputs (PT100, PT1000) to implement motor overheat protection.

20) Rapid Current Limiting: Prevents frequent overcurrent faults in the inverter, delivering exceptional load-handling capability.
