ABB ACS355-03U-01A2-4+B063 Motors & Drives - Safe Torque Off

Safe Torque Off is a core safety feature that helps you comply with machinery safety standards while reducing external hardware. By integrating STO and fault-safe protections into the drive, you minimize wiring, simplify safety circuits, and cut time to safe operation. In packaging lines and conveyors, that translates to faster start-ups, fewer nuisance trips, and safer maintenance windows. Built-in sequence programming lets you script simple automation routines inside the drive, reducing the need for a separate PLC for many tasks. The business impact is lower wiring complexity, faster commissioning, and easier troubleshooting because logic resides with the drive. Typical applications include material handling and lifting equipment where deterministic sequencing boosts throughput. ACS355 supports speed and torque control for AC induction and permanent magnet motors, enabling precise performance in mixed-mleet lines. This compatibility reduces spare parts and accelerators; energy efficiency improves with optimized ramping and closed-loop torque control. In food processing or textile machinery, smooth acceleration reduces product defects and extends motor life. Compact form factor, plug-and-play wiring, and a 0.5 HP, 1 A rating align with common OEM motor sizes and control cabinets. The drive tolerates standard low-voltage supplies and integrates with existing PLC ecosystems, easing retrofits on older lines. With ABB’s engineering, installation is quicker and serviceability is improved, minimizing downtime. Beyond basic functionality, the ACS355 contributes to regulatory and safety compliance, with CE safety considerations and documented performance. Its robustness supports continuous operation in demanding environments such as food & beverage, material handling, and woodworking. The result is a lower total cost of ownership through reduced hardware, lower energy use, and faster time-to-value.
