FAQs
The ACS550-02-368A-4 is designed to drive standard asynchronous AC motors within its 200 kW range and I2n 368 A current capability. It supports typical industrial loads such as pumps, fans, conveyors, and material-handling motors when paired with appropriate wiring, motor protection settings, and commissioning templates. Verify motor nameplate specs and may require matching voltage references and control wiring to ensure safe operation.
The drive enables precise speed control, soft-start and ramping, and optimized V/f curves, which minimize inrush and reduce wasted energy during acceleration and steady-state operation. By maintaining motor torque only as needed, it lowers overall energy consumption, lowers peak demand charges, and extends motor life, delivering a favorable return on investment in continuous-process and HVAC applications.
Yes. The IP21-rated enclosure is designed for indoor mounting in standard control cabinets and production line environments. Its compact footprint and simplified wiring support easy retrofits and clean integration into existing automation cabinets. When selecting mounting, ensure adequate ventilation and compliance with local electrical codes to maintain dependable operation.
The drive is CE certified, aligning with European safety, health, and environmental requirements. Its IP21 enclosure provides basic protection suitable for indoor environments. For facilities with additional compliance needs, verify any site-specific standards and consider complementary components or enclosures that meet local electrical and safety regulations.
ROI benefits come from energy savings, reduced motor wear, and improved uptime due to built-in diagnostics and protection. Maintenance is typically lower thanks to proactive fault detection and remote monitoring capabilities. Regular software updates, periodic parameter verification, and clean cooling paths help maximize reliability and extend the service life of the drive and connected motors.
