Danfoss 134F2976 FC-360H3K0T4E20H2BXCDXXSXXXXAXBX VLT AutomationDrive

Product Overview

The Danfoss 134F2976 (FC-360H3K0T4E20H3K0T4E20H2BXCDXXSXXXXAXBX) VLT AutomationDrive is a high-performance frequency converter designed for demanding industrial process control. Optimized for applications such as pump systems, centrifuges, and automated conveyor lines, this drive minimizes system downtime by providing precise motor torque and speed regulation. Built with a robust IP20 chassis and conformal-coated PCB, it ensures reliable operation in manufacturing environments where environmental contaminants are present. The unit supports critical industrial infrastructure by facilitating energy-efficient operation and reducing mechanical stress on motor-driven systems during start-up and transient load conditions.

Technical Configuration

The 134F2976 is configured for high-overload capability, specifically rated for a 3.0 kW (4.0 HP) power output within a 380-480 VAC three-phase network. It features an integrated RFI Class A2 filter for electromagnetic compatibility and a built-in brake chopper to handle regenerative energy during rapid deceleration. The hardware includes a DC load-sharing (Mains Option D) capability, allowing for energy management in multi-drive systems. Designed for flexible integration, this unit is supplied without a local display, utilizing a standard control card that supports the latest Danfoss standard software release, ensuring seamless integration into existing PLC-based automation architectures.

Technical Specifications

FAQs

What is the advantage of the load-sharing feature in this model?

The load-sharing option allows the DC bus of the drive to be connected to other drives in the system, enabling the redistribution of energy during braking cycles and improving overall energy efficiency across the factory floor.

Can this drive be used in high-vibration areas?

Yes, the VLT AutomationDrive FC-360 is built to handle standard industrial vibration levels; however, ensure the chassis is mounted to a rigid, grounded steel backplane to prevent resonance.

Is a display required for troubleshooting or parameter adjustment?

This model is supplied without an LCP (Local Control Panel). While operational control is managed via the terminal inputs, an external LCP or PC-based connection is required for monitoring, diagnostics, and parameter setting.

Is the conformal coating sufficient for chemical exposure?

The "C" code indicates the internal circuitry is coated to meet class 3C3 requirements (IEC 60721-3-3), offering significant protection against corrosive gases and humidity, common in process industries like chemical production or food processing.

Installation and Operational Guidelines

• Loadsharing Safety: When utilizing the Loadsharing (Mains Option D) functionality, ensure all connected drives share a common DC bus potential. Always perform a ground integrity check on the entire DC bus circuit before applying power to prevent catastrophic short-circuit failures.
• Thermal Management: The 134F2976 generates heat during operation. Ensure the control cabinet is equipped with filtered forced-air cooling. Maintain a minimum clearance of 100 mm at the top and bottom of the drive to ensure the internal airflow paths are unobstructed.
• Shielding for EMC: To maintain the efficacy of the integrated Class A2 RFI filter, connect the motor cable screen to the metal mounting plate using a 360-degree conductive clamp. This is critical for preventing high-frequency noise from affecting nearby instrumentation and PLC signals.
