ABB ACS600 AC Drive (ACS60401705 / ACS60401704)

Overview

The ABB ACS600 is a landmark AC drive platform that introduced Direct Torque Control (DTC) to the industrial market. Models ACS60401705 and ACS60401704 represent specific configurations within this series, designed for medium-power applications requiring high dynamic performance and accuracy. The DTC technology enables precise control of motor speed and torque without the need for a pulse encoder, simplifying installation and increasing system reliability.

Direct Torque Control (DTC) Technology

DTC is ABB's proprietary motor control method that directly controls the motor flux and torque. Unlike traditional PWM drives, DTC operates without a fixed switching frequency, resulting in:

• High Torque Accuracy: Typically within ±1% of nominal torque.

• Fast Dynamic Response: Torque step rise time below 5 ms.

• Wide Speed Range: Accurate control from zero speed to field weakening range.

• Encoderless Operation: Reduces hardware cost and cabling.

Key Features

• Flux Braking: Improves deceleration times without additional hardware.

• Integrated EMC Filter: Meets EN 61800-3 standards for reduced electromagnetic emissions.

• Adaptive Programming: Allows custom logic and application-specific functions.

• Fieldbus Compatibility: Supports PROFIBUS, DeviceNet, CANopen, and Modbus via optional modules.

• User-Friendly Control Panel: Multilingual display with real-time parameter editing and fault logging.

Technical Specifications

Typical Applications

The ACS600 series is widely used in industries such as pulp and paper, metals, mining, chemicals, and utilities. Common applications include:

• Centrifugal pumps and fans for flow control

• Conveyors and extruders requiring constant torque

• Mixers and agitators with variable load profiles

• Winders and unwinders demanding precise tension control

Reliability and Standards

Built with ABB's industrial-grade components, the ACS600 drives are certified with CE, UL, cUL, CSA, and C-Tick marks. They incorporate protective features such as overvoltage, undervoltage, overtemperature, and short-circuit protection, ensuring safe operation in harsh environments.

The ACS600 series, including models ACS60401705 and ACS60401704, represents a mature and trusted solution for variable speed control, backed by ABB's global service network and extensive application knowledge.
