FC-360H5K5T4E20H2BXCDXXSXXXXA0BX Danfoss VLT AutomationDrive FC 360

Product Overview

The FC-360H5K5T4E20H2BXCDXXSXXXXA0BX (134F2997) is a high-performance, cost-efficient frequency converter from the Danfoss VLT® AutomationDrive FC 360 series. Specifically rated for 5.5 kW (7.5 HP) under High Overload (HO) conditions, this drive is engineered to handle the rigorous torque demands of heavy-duty industrial machinery such as mixers, extruders, and palletizers. The FC-360H5K5T4E20H2BXCDXXSXXXXA0BX comes pre-configured with a Profibus DP control card, enabling seamless integration into Siemens-dominated automation architectures. Its compact IP20 chassis, combined with coated PCBs and an integrated brake chopper, provides a reliable power conversion solution that optimizes motor performance while ensuring high resistance to harsh industrial environments.

Suffix Breakdown

The technical capabilities of this FC 360 unit are defined by its specialized configuration string, tailored for high-demand networked environments:

• H5K5: High Overload (H) rating for 5.5 kW (7.5 HP) motors, allowing for superior starting torque.

• T4: Three-phase input range of 380-480 VAC, suitable for global industrial power grids.

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

• B: Built-in Brake Chopper, allowing the connection of an external resistor for rapid deceleration of high-inertia loads.

• C: Coated Printed Circuit Boards (PCB), providing essential protection against moisture and corrosive particles.

• D: Loadsharing option, enabling the DC bus to be linked with other drives for energy balancing.

• A0: Integrated Control Card with Profibus DP communication for high-speed fieldbus networking.

Technical FAQs

How do I commission the drive if it is supplied without a display (Suffix X)?

Since this model does not include a Local Control Panel (LCP), you can perform commissioning via the Profibus network using a GSD file in your PLC software. Alternatively, you can temporarily attach a VLT® Control Panel LCP 21 (Numerical) or LCP 102 (Graphical) to the front port or use the MCT 10 software through the built-in RS485 interface.

What is the advantage of the "High Overload" (H) rating for a 5.5 kW motor?

The High Overload rating allows the drive to provide up to 160 percent of its rated current for 60 seconds. This is critical for applications like heavy conveyors or positive displacement pumps that require significant torque to overcome static friction during startup.

Can this drive share energy with other units via the DC bus?

Yes, the "D" suffix indicates the Loadsharing option is present. This allows you to connect the DC terminals of multiple drives, allowing energy generated by a braking motor to be utilized by a motoring drive on the same bus, thereby increasing overall system energy efficiency.

Engineering & Installation Guide

• Profibus Termination: When installing the 134F2997 at the end of a Profibus segment, ensure the termination resistor on the Profibus connector is switched to the "ON" position. Use high-quality purple Profibus DP cable and maintain a minimum distance from high-voltage motor cables to prevent communication drops or telegram errors.

• Thermal and Space Management: The FC 360 supports side-by-side mounting, which is ideal for reducing the width of your control cabinet. However, because this is a High Overload 5.5 kW unit, ensure the vertical clearance (top and bottom) is at least 100 mm to allow the internal fans to maintain sufficient airflow through the heat sink.

• Brake Resistor Selection: To utilize the integrated brake chopper (Suffix B) for rapid stops, connect an appropriately sized external brake resistor to the B+ and B- terminals. Ensure the resistor's Ohmic value is not lower than the minimum specified in the Danfoss technical manual to avoid damaging the internal chopper transistor.
