Part Number: 3AUA0000232559
Quick Summary
The ABB ACS255-03U-30A0-2+B068 LV AC micro drive is designed to deliver precise motor control for pumps, fans, augers, mixers, and conveyors. In harsh industrial environments, startup friction, washdown exposure, and inconsistent signals can erode uptime and energy efficiency. This drive carries UL-listed protection with UL (NEMA) Type 4X and IP66 enclosure ratings, delivering corrosion-resistant performance indoors or outdoors. With sensorless vector control for both AC induction and PM motors, V/Hz profiles for variable and constant torque, and Modbus-RTU for real-time monitoring, it supports fast machine integration and predictable ROI in modern automation projects. In practice, it translates to smoother starts, reduced energy use, and easier commissioning for engineering teams.
Product Information
Extended Description
3AUA0000232559 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.
Integrated keypad for on‑machine configuration reduces commissioning time and simplifies parameter tuning, enabling faster startup and less reliance on external programming. This feature translates into lower project labor costs and quicker time‑to‑production on conveyors and processing lines. Sensorless vector control provides refined torque response for both AC induction and PM motors, delivering higher startup reliability and improved overall energy efficiency in pumps and fans without additional sensor hardware. The V/Hz control with variable torque and constant torque profiles optimizes performance across load ranges, reducing mechanical stress and energy waste in right-sized drives for inline mixers and augers. An IP66 / UL Type 4X enclosure with corrosion‑resistant materials extends service life in washdown environments, lowering maintenance and replacement costs in food processing and beverage lines. Embedded Modbus-RTU enables real-time control and monitoring within SCADA/PLC workflows, simplifying network integration and reducing fault diagnosis time. Enhanced short‑circuit protection adds a robust safety margin, supporting safer NRTL‑compliant deployments in automated material handling. Together, these capabilities deliver measurable improvements in uptime, energy efficiency, and total cost of ownership for industrial automation projects.
