Information About ACS355-03U-02A4-4BCM-MS/TP

The ACS355-03U-02A4-4 is a core automation component within ABB’s versatile ACS355 machinery drive portfolio. It is engineered with a modular, IP20-rated chassis that supports side-by-side DIN rail or panel mounting, making it highly advantageous for OEMs designing high-density electrical control cabinets. Automation technicians frequently deploy this drive in automated material handling, food and beverage processing, and packaging applications due to its built-in sequence programming functionality, which allows the drive to execute independent motion profiles without continuous PLC supervision. Additionally, the unit features an integrated dual-channel Safe Torque Off (STO) function, ensuring standard compliance with critical industrial safety regulations during mechanical maintenance.

Key Features:

● Precision Vector Control: Utilizes advanced sensorless vector algorithms to maintain strict motor speed and torque regulation across shifting mechanical loads.
● Built-In Safe Torque Off (STO): Integrates certified STO functionality (SIL 3 / PL e) to immediately remove motor generating power during emergency stops.
● Sequence Programming: Allows engineers to program independent logic and motion sequences directly into the drive, reducing the processing load on the central PLC.
● Compact Modular Design: Features a highly optimized, uniform physical frame that supports side-by-side mounting in space-constrained control panels.
● FlashDrop Compatibility: Supports the ABB FlashDrop tool for rapid, unpowered drive parameter configuration during high-volume OEM manufacturing.
● Integrated Brake Chopper: Includes a standard dynamic braking chopper to dissipate excess regenerative energy during rapid motor deceleration cycles.
The ACS355-03U-02A4-4 delivers the safety compliance and digital precision required for fast, highly coordinated machine automation.
