FAQs
Yes. The ACS355-03E-15A6-4 supports low-voltage, three-phase supplies and is suitable for AC induction and permanent magnet motors. Its built‑in safety features, like Safe Torque Off, simplify panel wiring and integration with common PLCs and fieldbus interfaces, reducing the need for additional controllers while preserving firm control over motor speed and torque.
Safe Torque Off provides a verifiable, instantaneous stop of motor torque without removing power. This reduces maintenance risk and simplifies safety compliance for conveyors, lifts, and handling lines. When combined with sequence programming, STO helps maintain deterministic shutdowns during faults or maintenance, improving overall plant safety and uptime.
Industries such as food and beverage, material handling, packaging, textiles, rubber and plastics, woodworking, and lifting equipment benefit from the ACS355. Its 7.5 kW rating and PM motor compatibility support mid‑scale automation projects, enabling precise speed control, energy efficiency, and safer operation in demanding manufacturing environments.
The ACS355 family aligns with common industrial safety expectations and CE machinery standards, supporting safe integration into regulated environments. While exact certifications can vary by region and configuration, the built‑in Safe Torque Off and programmable safety features help meet SIL‑based safety requirements and general machine protection guidelines observed in modern facilities.
Upgrading to the ACS355 reduces external control hardware needs, simplifies commissioning, and minimizes wiring, which lowers installation and maintenance costs. Energy‑efficient operation from precise speed control, coupled with reduced downtime thanks to STO and robust reliability, translates to a favorable total cost of ownership over the machine life cycle.
