Product Information
Extended Description
3AUA0000234193 ABB: The ACS255 drive comes in several variants ensuring seamless integration into machines. The UL (NEMA) TYPE 4X / IP66 ACS255 is constructed with corrosion resistant materials for durability and increased survival in wet, dirty, or washdown applications indoors or outdoors. Common application includes augers, mixers, pumps, fans and conveyors. The key features include an integrated keypad for easy configuration, precise process control with V/Hz control and sensorless vector control for both AC induction and PM motors, enhanced short circuit protection, operating mode selection with variable torque and constant torque V/Hz profiles, and embedded Modbus-RTU communication interface for real time control and monitoring.
Feature integration with business impact and application patterns are woven throughout the ACS255 offering. Feature → Business Impact → Application: The integrated keypad enables quick on-site configuration, reducing commissioning time and field errors, which accelerates time-to-production on new lines and minimizes downtime during changeovers. This translates to lower labor costs and faster return on investment for packaging lines and material handling systems. Feature → Business Impact → Application: Sensorless vector control paired with V/Hz operation provides precise speed and torque control for both AC induction and PM motors, improving process stability and product quality on conveyors, augers, and mixers. Practical applications include maintaining consistent fill rates in mixers and accurate flow control in pumps, with reduced need for separate servo drives. Feature → Business Impact → Application: IP66/UL 4X protection and corrosion-resistant construction deliver washdown-ready reliability, reducing maintenance cycles and equipment replacement in food processing, beverage, and outdoor installations. This supports compliance with strict hygiene norms and lowers lifecycle costs by minimizing unplanned outages. Feature → Business Impact → Application: Embedded Modbus-RTU communication offers straightforward integration into existing automation networks, enabling centralized monitoring, remote diagnostics, and scalable control across multiple drives on a single line. Industry context includes batch processing and continuous manufacturing where real-time feedback lowers energy waste and improves throughput. Feature → Business Impact → Application: Short-circuit protection, selectable torque profiles (variable and constant torque), and robust safety features protect equipment and extend motor life, reducing repair costs and improving overall OEE in pumps, fans, and conveyors. Industry advantage includes longer motor life in high-load start-stop cycles and better protection against motor stalls. Feature → Business Impact → Application: The architecture supports seamless installation in new or retrofitted machines, easing integration with existing ABB ACS255 variants and reducing custom engineering needs for machine builders. This helps ensure consistent performance across product families and quicker certification for machine builders.
