EC590 Series

General-Purpose Vector VFD

The EC590 Series is a general-purpose variable frequency drive that brings together vector-control technology and high-performance current vector control to drive induction motors. Designed for performance, quality and power density, it improves versatility, ease of use, maintainability, environmental considerations and installation efficiency to support a better user experience.

Key features

The EC590 Series is a general-purpose variable frequency drive built on advanced vector-control technology.
Supports V/F and sensorless vector control (SVC) for both induction motors (IM) and permanent-magnet motors (PM), with application functions including torque and PID control.
Allows one-touch switching between control functions for induction and permanent-magnet motors.
Uses IGBT modules from major suppliers such as Fuji and Starpower, with customized options available. A 32-bit ARM processor, dedicated short-circuit protection chip, high-quality capacitors and modular PCB design support protection and real-time monitoring.
Features an adjustable-speed cooling fan with dual-ball-bearing NMB fans and hot-plug support, housed in an ABS flame-retardant enclosure.
All models support wall-mounted installation.
A detachable, hot-pluggable keypad supports RJ45 extension cables up to 30 m and a two-line LED display.
Built-in power and status indicators remain visible for on-site operation and monitoring when the keypad is removed.
Firmware can be upgraded through USB or a serial connection. One-touch application macros are available for fans, water pumps and other equipment.
A standard RS485 port supports Modbus RTU communication.
