EC700 Series

High-Performance Industry VFD

The EC700 Series is a high-performance industrial variable frequency drive designed for diverse load requirements and applications. Built for industrial OEMs that demand quality and performance, it combines advanced control algorithms, modular functions and dual expansion interfaces to support speed control and energy-efficient operation across a wide range of equipment. It works with both induction and permanent-magnet synchronous motors, supports multiple mounting options, and offers optional LED and LCD keypads. From simple machinery to precision automation systems, the EC700 Series delivers flexible, accurate motor control.

Key features

Engineered for diverse loads and a wide range of industrial applications, the EC700 Series is designed to meet the quality and performance requirements of industrial OEM customers.
Supports V/F, sensorless vector control (SVC) and flux vector control (FVC) 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.
The 0.4–400 kW range supports wall mounting, while 0.4–37 kW models also support through-wall mounting.
A detachable, hot-pluggable keypad supports parameter copying and RJ45 extension cables up to 30 m. Optional two-line LED and LCD keypads are available.
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. The drive supports parameter reading and writing, status monitoring and fault tracing, plus one-touch application macros for fans, water pumps and other equipment.
A standard RS485 port supports Modbus RTU. PN and TCP/IP communication options help connect the drive to industrial networks, PLCs and HMIs for remote monitoring and data exchange.
Two expansion interfaces support optional I/O and communication modules, ABZ-PG cards, constant-pressure water-supply cards and other expansion cards.
