Product Overview

The FC-360H11KT4E20H2BXCDXXSXXXXA0BX (134F2999) is a heavy-duty 11 kW (15 HP) frequency converter from the Danfoss VLT® AutomationDrive FC 360 series. Engineered for high-overload industrial applications, this drive delivers exceptional reliability in demanding sectors such as textile manufacturing, food processing, and material handling. The FC-360H11KT4E20H2BXCDXXSXXXXA0BX is specifically designed to handle high-torque demands with a 160% overload capacity. Featuring coated PCBs for environmental resilience and a built-in Profibus-ready control card, this drive offers a cost-effective yet powerful solution for complex automation environments requiring precise speed control and robust fieldbus communication.

Suffix Breakdown

The technical capabilities of this FC 360 unit are defined by its comprehensive configuration string:

• H11K: High Overload (H) rating for 11 kW (15 HP) motors, ideal for high-inertia startups.

• T4: Three-phase mains voltage compatibility from 380 - 480 VAC.

• E20: IP20 enclosure rating, optimized for mounting within protected electrical cabinets.

• H2: Integrated RFI Class A2 filter, ensuring compliance with industrial electromagnetic interference standards.

• B: Integrated Brake Chopper, allowing for rapid motor deceleration when connected to a brake resistor.

• C: Coated Printed Circuit Boards (PCB), providing superior protection against humidity and conductive dust.

• D: Loadsharing option, enabling the connection of the DC bus between multiple drives for energy balancing.

• A0: Standard Control Card with Profibus DP communication capabilities.

Technical Specifications

Technical FAQs

How can I configure parameters if the unit has no display (Suffix X)?Since this model is supplied without a Local Control Panel (LCP), commissioning is typically performed via the Profibus network or through the Danfoss MCT 10 setup software using the RS485 port. Alternatively, a blind cover or an LCP 21/LCP 102 can be temporarily attached for local manual configuration.

What are the benefits of the Loadsharing (Suffix D) option?The Loadsharing option allows you to link the DC links of several drives. This is highly efficient in applications where one drive is braking (generating energy) while another is motoring; the energy can be shared across the DC bus, reducing overall power consumption and minimizing the need for large brake resistors.

Is this drive suitable for environments with textile fibers or high humidity?Yes. The "C" suffix indicates that the PCBs are coated with a conformal layer. This makes the 134F2999 highly resistant to the corrosive effects of moisture and the conductive nature of dust or fibers commonly found in textile and woodworking industries.

Engineering & Installation Guide

• Profibus Networking: Ensure the Profibus cable is properly shielded and that the termination resistors are set correctly at the first and last nodes of the segment. Keep the Profibus data lines separate from the 380-480V motor cables to prevent data packet corruption from electromagnetic interference.

• Thermal Management: The 11 kW FC 360 generates significant heat during high-overload operation. Maintain a minimum of 100 mm vertical clearance above and below the chassis. Although side-by-side mounting is supported, ensure the cabinet's internal ambient temperature remains within the specified operating limits (typically up to 45 deg C without derating).

• Brake Resistor Safety: If utilizing the integrated brake chopper for rapid stops, ensure the external brake resistor is mounted outside the main drive enclosure or in a well-ventilated area, as it will dissipate heat. Use heat-resistant cables for the B+ and B- connections.
