ABB 3AUA0000234204 LV AC micro drive - IP66
Part Number: 3AUA0000234204
Quick Summary
ABB ACS255 LV AC micro drive provides precise speed control for washdown-ready machinery like pumps and conveyors. Many machines struggle with corrosion, water ingress, and downtime when drives aren’t rugged enough for harsh environments. This drive carries UL Type 4X/NEMA ratings and IP66 protection for indoor and outdoor washdown use, ensuring long life in wet or dirty surroundings. By integrating Modbus-RTU communication, an easy-to-use keypad, and advanced V/Hz and sensorless vector control, it reduces commissioning time, lowers maintenance costs, and delivers steady throughput in demanding automation lines.
Product Information
Extended Description
3AUA0000234204 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 → Business Impact → Application. The integrated keypad and compact enclosure simplify field configuration, dramatically reducing commissioning time and the need for external programming tools, which translates to lower startup costs on new packaging and assembly lines. This ease of setup pairs with 240 V operation to support common industrial power systems, enabling straightforward replacement of legacy drives in machines like augers and mixers, while minimizing downtime during upgrades. Feature → Sensorless vector control with V/Hz drive performance improves torque accuracy and starting reliability without extra sensors, delivering energy efficiency and smoother ramping for pumps and fans, especially where precise speed control matters for process stability. Feature → Modbus-RTU communication provides real-time monitoring and PLC integration, enabling centralized diagnostics, remote parameter updates, and reduced on-site maintenance for conveyors and material-handling systems. Feature → UL Type 4X / IP66-rated housing and corrosion-resistant construction address harsh environments, allowing outdoor or washdown installations without compromising reliability or safety. Feature → Variable torque and constant torque V/Hz profiles, along with enhanced short-circuit protection, support a broad range of loads—from centrifugal fans to high-start-load conveyors—while meeting compliance and safety expectations in industrial facilities.

FAQs
The ACS255 is designed with a rugged IP66/UL Type 4X enclosure, enabling installation in wet, dusty, and washdown areas. Plan for proper mounting, secure cable entry, and proper sealing to maintain protection. The integrated keypad simplifies commissioning, and Modbus-RTU wiring supports PLC integration without additional adapters.
Sensorless vector control provides accurate torque and smooth speed regulation without external sensors, improving startup torque, slow-speed stability, and energy efficiency for both AC induction and PM motors. This reduces wear, lowers energy consumption, and yields more reliable operation in pumps, fans, and conveyors.
Yes. The ACS255 is configured for 240 V systems and supports both AC induction and PM (permanent magnet) motors. This compatibility simplifies retrofits and replacements on existing equipment without major electrical rewiring or power system changes.
The drive features UL Type 4X and IP66 protection, offering ruggedness for harsh indoor and outdoor environments. This combination supports compliance for washdown areas and corrosive environments commonly found in industrial facilities.
Expect reduced downtime due to rugged IP66/4X protection, lower energy usage from V/Hz with torque profiling, and faster commissioning via the onboard keypad and Modbus-RTU integration. The result is improved throughput, longer motor life, and lower total cost of ownership over the system’s life cycle.
