This combination translates to higher equipment reliability, improved energy efficiency, and lower total cost of ownership in demanding automation tasks.
Product Information
Extended Description
3AUA0000234217 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 minimizes field wiring errors, speeding up deployment on conveyors and pumps. The drive supports V/Hz control and sensorless vector control, delivering precise torque and speed profiles that improve process stability while reducing energy consumption. Rugged housing with UL Type 4X / IP66 protection and corrosion‑resistant materials ensures uptime in washdown environments and outdoor installations, extending equipment life. Embedded Modbus-RTU enables seamless PLC communication and real‑time data exchange for tight process control and monitoring. Enhanced short‑circuit protection and fault handling lower the risk of motor damage, translating to fewer maintenance events and lower repair costs. The option of variable torque and constant torque V/Hz profiles provides energy savings and better control for pumps, fans, and conveyors under varying load conditions. Multiple variants support easy integration into existing machinery, minimizing redesign and installation effort.

FAQs
Install ACS255 by mounting in a protective enclosure suitable for washdown, connect to a 480 V 3-phase supply, and wire the motor as per the user manual. Use the built‑in keypad for initial configuration and connect the Modbus-RTU interface to the PLC for real-time control and monitoring. Ensure proper grounding and confirm that the motor type (AC induction or PM) is compatible with sensorless vector control for optimal torque response.
ACS255 supports both AC induction and permanent magnet (PM) motors with sensorless vector control, plus V/Hz profiles for basic speed control. This enables precise torque and speed management, improved startup behavior, and energy efficiency across varying load conditions, which is ideal for conveyors, augers, and mixers.
Yes. The drive features UL Type 4X / IP66 protection with corrosion‑resistant construction, making it well suited for washdown environments, wet, dirty, or outdoor installations, and reducing corrosion-related downtime in challenging facilities.
The ACS255 is designed with UL (NEMA) Type 4X / IP66 protection to withstand harsh environments. This helps ensure reliability in demanding industrial settings and supports safe operation in wet or washdown areas.
ROI is driven by reduced commissioning time thanks to the onboard keypad, energy savings from V/Hz and torque profiles, and lower maintenance due to enhanced protection and fault handling. Real-time monitoring via Modbus-RTU also enables proactive maintenance and tighter process control, delivering lower total cost of ownership over the equipment lifecycle.
