Danfoss 134F2993 FC-360H15KT4E20H2BXCDXXSXXXXA0BX VLT AutomationDrive

Product Overview

The Danfoss 134F2993 (FC-360H15KT4E20H2BXCDXXSXXXXA0BX) is a high-performance VLT AutomationDrive engineered for demanding motor control applications. This model is specifically optimized for high-overload environments, providing the torque capacity necessary for machinery that undergoes frequent load fluctuations, such as industrial extruders, heavy-duty mixers, and conveyor systems. By utilizing advanced frequency regulation and load-sharing capabilities, the 134F2993 enhances operational efficiency and minimizes mechanical fatigue, ensuring superior reliability in mission-critical manufacturing workflows.

Technical Configuration

The 134F2993 belongs to the FC-360 series, a platform that balances high-end control functionality with industrial-grade durability.

• Hardware Architecture: Rated for 15 kW (20 HP) output, this drive operates on a three-phase 380 - 480 VAC supply. It features an IP20-rated chassis designed for integration into ventilated electrical control panels.
• Connectivity & Control: This specific unit includes a Control Card with Profibus (A0), enabling seamless integration into complex industrial fieldbus networks for real-time process monitoring and centralized control.
• Operational Versatility: The drive includes an integrated brake chopper (B) for rapid deceleration and a Loadsharing (D) option, allowing it to distribute energy efficiently across a shared DC bus—a key feature for reducing total energy consumption in multi-drive systems.
• Environmental Hardening: The PCBs are conformal coated (C), protecting internal logic components from humidity, conductive dust, and chemical vapors commonly found in industrial production halls.

FAQs

How does the integrated Profibus (A0) control card benefit my automation setup?

The Profibus A0 card allows the drive to act as a slave device on a Profibus-DP network. This provides high-speed communication with a master PLC, enabling precise speed control, parameter adjustment, and deep diagnostic feedback without the need for individual hard-wired control signals.

Can I operate this drive without an external control display?

Yes, this model (X) is configured without a factory-mounted Local Control Panel (LCP). It is designed to be commissioned and operated primarily through the Profibus network or via an optional snap-on LCP if local manual intervention is required.

What is the advantage of the "High Overload" rating?

High Overload drives are sized to handle a higher percentage of their nominal current for short durations compared to standard drives. This is vital for processes that require a high breakaway torque to start a machine under load.

Engineering Guidelines and Best Practices

• Thermal Management: The 15 kW rating necessitates effective cabinet ventilation. Maintain the recommended clearance distances (typically 100 - 150 mm) above and below the unit. Periodically inspect the heatsink fins to ensure they are free of dust buildup, which can significantly reduce cooling efficiency.
• Profibus Wiring: When connecting the Profibus A0 card, use specialized Profibus-rated cabling with the correct impedance characteristics. Ensure that the bus is correctly terminated at both physical ends of the network segment to prevent signal reflections that cause communication errors.
• EMI Mitigation: Even with the H2-rated internal RFI filter, you must use shielded motor cables. Terminate the shield at both ends using a 360-degree conductive clamp to the chassis or motor frame. This is crucial for maintaining the integrity of the Profibus communication against high-frequency noise generated by the drive.
