Danfoss 134F2980 FC-360H11KT4E20H2BXCDXXSXXXXAXBX VLT AutomationDrive

Product Overview

The Danfoss 134F2980 (FC-360H11KT4E20H2BXCDXXSXXXXAXBX) is a robust VLT AutomationDrive designed to provide high-performance motor control in demanding industrial environments. This drive is specifically engineered for high-overload applications, making it an ideal choice for heavy-duty processes such as extruders, mixers, and conveyor systems that experience significant torque fluctuations. By optimizing motor performance and energy efficiency, the 134F2980 plays a vital role in reducing operational overhead and preventing mechanical failure, ensuring consistent uptime in critical manufacturing and process control settings.

Technical Configuration

The 134F2980 is part of the FC-360 series, a platform built for reliability and flexibility in standard-to-demanding automation tasks.

• Hardware Architecture: Configured for 11 kW (15 HP) motor loads, the unit operates on a three-phase 380 - 480 VAC supply. It features an IP20-rated chassis designed for integration into standard electrical cabinets.
• Operational Control: This model includes an integrated brake chopper (B), allowing for the dissipation of regenerative energy—essential for high-inertia loads. It also supports load-sharing (D), which enables energy distribution across multiple drives in a single DC bus system.
• Environmental Hardening: The internal electronics utilize coated PCBs (C), providing enhanced protection against dust, humidity, and corrosive chemical vapors, ensuring longevity in harsh industrial conditions.
• EMC Compliance: The unit is equipped with a Class A2 RFI filter (H2), ensuring compliance with electromagnetic compatibility standards in industrial network environments.

Technical Specifications

FAQs

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

The loadsharing option allows the drive to be connected to a shared DC bus with other drives. This enables energy transfer from a decelerating motor to one that is motoring, significantly increasing overall system energy efficiency and reducing heat generation.

Does this drive come with a display unit?

No, this specific configuration (X) is supplied without a Local Control Panel (LCP) or blind cover. If local programming and status monitoring are required, an external LCP must be purchased and mounted.

Is this drive suitable for heavy-duty start-up applications?

Yes, the "H" prefix in the series designation confirms it is rated for High Overload. It is specifically designed to handle the increased current demand during the starting phase of high-inertia loads without triggering nuisance trips.

Engineering Guidelines and Best Practices

• Thermal Management: To ensure a long service life, provide at least 100 mm of clearance around the top and bottom of the drive for effective air circulation. Avoid placing the unit near heat-sensitive components or in areas with poor ambient airflow.
• Braking Resistor Selection: Since an internal brake chopper is included, an external braking resistor must be sized correctly based on the application's duty cycle. Ensure that the resistor is mounted in a well-ventilated area to dissipate heat safely away from the drive and control panel.
• Signal Integrity: Always use shielded cables for motor connections. The shield should be terminated using 360-degree clamps at both the motor terminal box and the drive chassis to ensure the RFI protection is effective and to minimize electromagnetic noise impact on neighboring sensors and control lines.
