Lenze I55AE137B10V10000S i550 Series AC Inverter Drive

Engineered for space-restricted control cabinets, the Lenze I55AE137B10V10000S frequency inverter delivers precise speed and torque regulation for low-power motor systems. This compact drive converts single-phase 230V mains power into a variable-frequency three-phase output, making it highly suitable for running small three-phase AC motors from standard single-phase utility grids. As part of the reliable Lenze i550 series, this unit features a slim profile and high energy efficiency, minimizing thermal load inside industrial enclosures.

Key Features

• Phase Conversion: Efficiently converts 1-phase 230 VAC input to 3-phase 230 VAC output for standard industrial motors.
• Compact Footprint: Slim design allows side-by-side mounting in control panels, optimizing cabinet space.
• IP20 Protection: Designed for clean, dry industrial environments with standard finger-safe terminal connections.
• Scalable Integration: Fully compatible with the modular Lenze i500 range of communication and interface options.

Applications

• Conveyor Systems: Precise speed control for small-scale material handling and packaging lines.
• Pumps and Fans: Energy-efficient flow regulation in commercial HVAC and fluid transfer systems.
• Machine Tooling: Spindle and auxiliary axis control in light-duty manufacturing machinery.

Alternative Models & Compatibility

The i550 series serves as the modern, high-efficiency replacement for legacy Lenze 8200 vector series drives. When migrating older systems to the i550 platform, parameter sets must be converted using the Lenze Easy Starter software tool, as direct parameter file transfers are not supported due to differences in firmware architecture.

Application Pitfalls & Engineering Notes

Because this unit is IP20 rated, it relies heavily on convective airflow for cooling. In enclosed control panels, maintain a minimum clearance of 50 mm above and below the drive. Failure to provide adequate clearance under continuous 0.37 kW loads can lead to premature thermal tripping or overtemperature faults (Fault Code 0x2310).

Commissioning & Wiring Tips

Always ground the motor cable shield directly to the metal mounting plate using low-impedance EMC shield clamps. This prevents high-frequency common-mode currents from leaking into nearby sensor wiring, which can cause intermittent signal corruption on analog feedback loops.
