FC-051P2K2S2E20HXBXCXXXSXXX Danfoss VLT Micro Drive FC 51 Variable Frequency Drive

Product Overview

The FC-051P2K2S2E20HXBXCXXXSXXX (FC051P2K2S2E20HXBXCXXXSXXX) represents a high-efficiency solution within the Danfoss VLT Micro Drive series, engineered for compact performance in demanding industrial environments. This 2.2 kW (3.0 HP) variable frequency drive (VFD) is specifically designed to optimize motor control in applications such as conveyor systems, pumping stations, and industrial fans. By integrating a built-in brake chopper and coated PCBs as standard, this unit ensures maximum uptime and reliability in harsh conditions characterized by moisture or dust. In critical sectors like food and beverage processing or warehouse automation, the FC 51 minimizes energy consumption while providing the precise torque control necessary to prevent mechanical wear and reduce unplanned downtime.

Technical Specifications

Technical FAQs

How do I configure this drive if it is supplied without a Local Control Panel (LCP)?

The unit can be programmed using an external LCP 11 or LCP 12 accessory. Alternatively, engineers can utilize the MCT 10 Setup Software via an RS485 interface to configure parameters, clone settings, and perform diagnostics from a PC.

What are the benefits of the 'C' suffix (Coated PCB) in this model?

The protective coating shields the internal electronics from aggressive gases, humidity, and airborne contaminants. This is critical for maintaining dielectric strength and preventing corrosion in environments like wastewater treatment or chemical processing.

Is an external braking resistor required for this specific unit?

Since this model features a built-in brake chopper (B suffix), it can dissipate regenerative energy. However, an external braking resistor must be connected to the terminals if the application involves high-inertia loads or rapid deceleration cycles.

Engineering & Installation Guide

• Thermal Management & Clearance: For IP20 chassis mounting, ensure a minimum of 100 mm clearance above and below the unit to allow for natural convection and forced air flow. These drives can be mounted side-by-side (bookstyle) without derating, significantly saving cabinet space.

• EMC Compliance & Shielding: Since this specific model (HX) does not include an internal RFI filter, you must use shielded motor cables and ensure 360-degree grounding at both the drive and motor ends to mitigate electromagnetic interference. Keep control wiring and power cables separated by at least 200 mm.

• Brake Chopper Protection: When connecting an external braking resistor, use twisted-pair cabling to reduce EMI. Ensure the resistor is mounted horizontally and away from heat-sensitive components, as surface temperatures can exceed 200 deg C during heavy braking cycles.
