Danfoss 132F0028 VLT Micro Drive FC 51 5.5 kW Frequency Inverter

Product Overview

The 132F0028 (FC-051P5K5T4E20H3BXCXXXSXXX) is a robust, high-efficiency frequency inverter from the Danfoss VLT Micro Drive FC 51 series. Rated for 5.5 kW (7.5 HP) and designed for three-phase 380–480 VAC operation, this drive is a versatile solution for industrial motor control in applications such as centrifugal pumps, material handling conveyors, and HVAC ventilation systems. Its compact IP20 chassis is engineered to maximize installation density within electrical cabinets, while the inclusion of coated PCBs ensures long-term operational reliability in environments where dust, moisture, or mild corrosive elements may be present.

Technical Configuration

This configuration is optimized for high-performance integration, featuring an integrated RFI filter (H3, Class A1/B) to meet stringent electromagnetic compatibility requirements in diverse industrial and commercial networks. It includes an integrated brake chopper, enabling efficient management of kinetic energy during deceleration cycles. For advanced control flexibility, the drive offers five programmable digital inputs, two analog inputs, and a pulse input frequency range up to 5000 Hz. The drive is provided without a Local Control Panel (X), making it an ideal choice for systems utilizing remote HMI or PLC-based control via fieldbus or hardwired I/O.

Technical Specifications

FAQs

What is the benefit of the H3 (Class A1/B) RFI filter?

The H3 filter provides advanced electromagnetic interference suppression. It is essential for ensuring that the drive complies with stringent EMC standards, preventing high-frequency noise from disrupting other sensitive electronic equipment on the same power grid.

Does this drive support dynamic braking?

Yes, this model features an integrated brake chopper (B). By connecting an external brake resistor, you can safely dissipate the energy generated by the motor during rapid deceleration or when managing high-inertia loads.

Can I monitor the drive locally without an LCP?

This specific unit (X) is configured without an integrated LCP. However, if local monitoring becomes necessary in the future, the FC 51 series supports the addition of external display panels or remote configuration via the standard RS-485 interface.

Are the inputs and outputs configurable?

Yes, the drive includes five programmable digital inputs and two analog inputs, allowing you to tailor the control logic (e.g., start/stop, multi-speed presets, or sensor feedback loops) to meet specific process requirements.

Installation and Operational Guidelines

• Airflow Requirements: The IP20 chassis relies on natural convection and forced-air cooling. Ensure there is at least 100 mm of clearance above and below the drive. For a 5.5 kW unit, verify that the cabinet's internal fans are adequately rated to dissipate the heat generated at full load.

• Shielding and Grounding: Always use shielded cable for the motor connection. Connect the shield to the drive’s designated ground point using a 360-degree conductive clamp to minimize electromagnetic emissions and comply with CE/EMC directives.

• Terminal Maintenance: Check all mains and motor terminals during initial commissioning. Due to the higher current (12 A) handled by this 5.5 kW model, terminal resistance is a critical factor; ensure all connections are torqued to the manufacturer’s specification to prevent localized overheating.
