Danfoss 134F2973 VLT AutomationDrive FC 360 Convertisseur de fréquence 1,1 kW

Product Overview

The 134F2973 (FC-360H1K1T4E20H2BXCDXXSXXXXAXBX) is a high-performance frequency converter from the VLT AutomationDrive FC 360 series, specifically optimized for high-overload industrial applications. Rated for 1.1 kW (1.5 HP), this drive provides precise torque and speed control for machinery requiring robust handling of high-starting loads, such as mixers, extruders, and conveyors. By leveraging advanced internal control loops, the unit enhances energy efficiency and protects mechanical drive trains from peak-load stress, significantly extending the service life of critical production assets in demanding manufacturing environments.

Technical Configuration

This drive is engineered for reliable operation on 380-480 VAC three-phase networks and is housed in a compact IP20/chassis enclosure, designed for integration into climate-controlled electrical panels. The unit includes an integrated brake chopper (B) for applications requiring dynamic deceleration and a load-sharing (D) option for energy-efficient multi-drive configurations. To ensure durability against industrial contaminants, the internal printed circuit boards (PCBs) feature a protective Class C coating. For network compliance, the integrated Class A2 RFI filter effectively suppresses electromagnetic emissions, allowing for seamless integration into industrial power grids.

Technical Specifications

FAQs

What are the primary benefits of the "High Overload" (H) rating?

The high-overload rating indicates that the drive is specifically built to handle heavy start-up currents and intermittent peak torques required by demanding applications like crushers or heavy-duty conveyors, without triggering thermal protection trips.

Does this model include a local display?

No, this specific configuration (X) is provided without a display or blind cover, designed for applications where the drive is controlled remotely via a fieldbus or an external HMI.

What is the purpose of the Loadsharing (D) option?

The loadsharing option allows multiple drives on a common DC bus to share energy, particularly beneficial in systems where one drive is generating power during braking while another requires power during acceleration, resulting in significant energy savings.

Is this drive suitable for corrosive environments?

Yes, the inclusion of coated PCBs (Class C) provides a vital layer of protection against corrosive gases and moisture, making this drive suitable for use in environments where standard unprotected electronics would otherwise degrade rapidly.

Mechanical Installation & Operational Guidelines

• Thermal Management: The FC 360 drive must be mounted vertically to facilitate convective cooling through the heatsink. Maintain a minimum clearance of 100 mm above and below the chassis. Avoid installing the drive in locations where it will be exposed to exhaust air from other high-heat components.

• EMC Integrity: To maintain compliance with EMC standards, ensure motor cables are shielded and terminated using 360-degree clamps at the drive's entry point. Keeping motor cables separated from control and signal wiring is essential to prevent electromagnetic interference.

• Torque Protocols: Always verify terminal screw tightness during commissioning. High-vibration environments can cause power and control connections to loosen over time; use a calibrated torque tool to ensure all cable connections meet the manufacturer's specified values to prevent resistive heating at the terminals.
