FAQs
The drive features IP66/UL Type 4X protection and corrosion-resistant materials suitable for washdown and outdoor use. Plan for proper cable gland entries, heat dissipation, and compliant enclosure mounting. Ensure Modbus-RTU wiring is routed away from high-noise sources and allow space for cooling and keypad access for on-site parameter adjustments.
ACS255 provides sensorless vector control for both AC induction and PM motors, plus V/Hz control with variable and constant torque profiles. This delivers precise speed control, smoother starts, and reduced motor wear, resulting in energy savings and improved process stability across fans, conveyors, and pumps.
Yes. With 480 V operation, integrated keypad, and Modbus-RTU for real-time control, the ACS255 supports common applications like pumps and conveyors. Its torque profiles and robust protection help maintain throughput in harsh environments, while easy commissioning accelerates deployment on new lines or retrofits.
The drive is rated IP66 and UL Type 4X with a CE designation, ensuring protection against washdown, environmental exposure, and compliance with European and North American safety standards. This simplifies regulatory approvals for global installations and helps meet industry requirements for food, beverage, and packaging sectors.
ROI is enhanced through reduced downtime, faster commissioning with an integrated keypad, and real-time visibility via Modbus-RTU. Sensorless vector control minimizes motor wear, and rugged protection reduces maintenance frequency, delivering faster payback and improved overall equipment effectiveness (OEE) on critical lines.
