FAQs
Installation begins with confirming low-voltage three-phase supply compatibility and motor type (AC induction or permanent magnet). Connect the drive to the motor, set basic parameters for power, rpm range, and direction, then enable Safe Torque Off as a safety feature. Use the built-in sequence programming to implement simple automation sequences, reducing external controllers. Ensure proper enclosure protection and grounding per site standards to minimize EMI and improve reliability.
Key specifications include 4 kW rated power and 17.6 A rated current, which define load capability for mid-size pumps and conveyors. The drive supports speed and torque control for precise motor response, and STO enhances safety. Consider motor type (AC induction or PM), required speed range, and efficiency targets when selecting this drive for a specific application.
Yes, its ACS355-based platform is suitable for solar pump drives and general-purpose conveyors due to its wide motor compatibility and robust control features. The integrated STO and sequencing capabilities help protect operators while enabling efficient pump sequencing in solar-irrigation setups and consistent conveyor performance in packaging or material handling lines.
When evaluating drives for regulated environments, verify CE compliance for European markets, appropriate IP protection for enclosure environments, and safety-related standards relevant to your risk assessment. While the drive includes built-in safety features like Safe Torque Off, confirm your system-level certifications and site requirements to ensure full compliance across your automation stack.
ROI is driven by reduced wiring, fewer external controllers, and faster commissioning, translating to lower installation and labor costs. The integrated motor control features improve uptime and product consistency, while uniform parts across multiple lines reduce spare-part inventories. Regular firmware updates and standard ABB service channels support ongoing maintenance and optimizations.
