Variateur micro VLT FC 51 2.2kW Danfoss FC-051P2K2T4E20HXBXCXXXSXXX

Product Overview

The FC-051P2K2T4E20HXBXCXXXSXXX (136N8929) is a highly efficient and ultra-compact frequency converter from the Danfoss VLT Micro Drive series. Engineered for a power rating of 2.2 kW (3.0 HP), this drive is a premier choice for industrial motor control where panel space is at a premium. It is widely utilized in sectors such as food and beverage processing, packaging, and textile manufacturing to provide precise speed and torque control for three-phase AC motors. The FC-051P2K2T4E20HXBXCXXXSXXX is designed with durability in mind, featuring coated PCBs to resist harsh industrial environments, thereby significantly extending the service life of the drive and reducing total cost of ownership through energy savings and reduced mechanical wear.

Suffix Breakdown

The specific capabilities of this VLT Micro Drive are defined by its detailed configuration string, ensuring it meets exact application requirements:

• P2K2: Indicates a power rating of 2.2 kW (3.0 HP).

• T4: Designed for three-phase mains voltage input between 380 - 480 VAC.

• E20: IP20 enclosure rating (Chassis), optimized for mounting within a protected control cabinet.

• HX: No RFI Filter version, suitable for environments where external filtering is managed or in installations where high-frequency leakage current must be minimized.

• B: Integrated Brake Chopper, allowing the drive to connect to a brake resistor for fast deceleration and managing regenerative energy.

• C: Coated PCB, providing a protective layer against moisture, dust, and chemical contaminants.

• X (LCP): Standard unit supplied without a Local Control Panel; requires an external LCP or software interface for commissioning.

Technical Specifications

Technical FAQs

How do I program the FC 51 if it comes without a Local Control Panel (LCP)?

Since this model has the "X" suffix for the LCP, you can program it using a separate LCP 11 (without potentiometer) or LCP 12 (with potentiometer) module. Alternatively, you can use the Danfoss MCT 10 setup software via the built-in RS485 port for more complex parameter configurations.

What is the benefit of the Coated PCB for this 2.2 kW drive?

The "C" suffix denotes that the circuit boards are treated with a conformal coating. This protects the electronics from corrosion and short circuits in environments with high humidity or conductive dust, common in woodworking or chemical processing plants.

Does this drive require an external RFI filter for industrial use?

As an "HX" model, it does not have a built-in RFI filter. While it will function perfectly, you may need an external RFI filter to meet specific EMC (Electromagnetic Compatibility) standards if the drive is installed near sensitive electronic equipment or in residential/commercial zones.

Engineering & Installation Guide

• Compact Mounting Strategy: The VLT Micro Drive supports true side-by-side mounting. You can install multiple FC-051P2K2T4E20HXBXCXXXSXXX units directly next to each other without air gaps, significantly reducing the size of your electrical cabinet. Ensure at least 100 mm of free space above and below the drive for natural convection cooling.

• Braking Resistor Connection: To utilize the integrated brake chopper for high-inertia loads or rapid stops, connect an external brake resistor to terminals R+ and R-. Ensure the resistor is sized according to the 2.2 kW power rating and the duty cycle of your application to prevent overheating of the braking circuit.

• Cable Shielding and Grounding: For the "HX" version, proper grounding is essential. Use shielded motor cables and ensure the shield is clamped to the drive's decoupling plate with a 360 degree connection. This minimizes electromagnetic noise and ensures stable operation of the drive and nearby sensors.
