134F2984 | Danfoss | Frequency Converter

Product Overview

The Danfoss 134F2984 (FC-360H30KT4E20H2XXCDXXSXXXXAXBX) VLT AutomationDrive is a high-capacity frequency converter engineered for heavy-duty industrial motor control. Capable of handling a 30 kW (40 HP) load, this unit is specifically designed for high-overload applications in sectors such as manufacturing, large-scale pumping, and material processing. By providing precise speed regulation and reducing mechanical stress during high-torque startup phases, the drive significantly mitigates equipment wear and prevents unplanned system downtime. Its chassis-based IP20 architecture and factory-applied conformal coating ensure reliability in demanding plant environments, making it a critical asset for maintaining continuous industrial production.

Technical Configuration

The 134F2984 is configured as a robust power conversion solution for 380-480 VAC three-phase grids. The unit features an integrated Class A2 RFI filter to minimize electromagnetic interference within the facility. Unlike smaller drives, this model incorporates a DC load-sharing (Mains Option D) interface, allowing for efficient energy distribution across multi-drive industrial architectures. The hardware is supplied without an internal brake chopper or local display, focusing on high-efficiency performance and seamless integration into automated PLC control systems via its standard control card. The PCB is conformal coated ("C") to protect internal components against oxidation and contaminants, ensuring a prolonged operational lifecycle.

Technical Specifications

FAQs

What is the purpose of the Loadsharing (Mains Option D) capability?

Loadsharing enables the DC bus of the drive to be linked with other compatible drives, allowing the system to share regenerated energy between units, which reduces power consumption and heat output.

Since this model has no brake chopper, how is regenerative energy managed?

Without an internal brake chopper, this drive is optimized for applications that do not require high-energy dynamic braking. If the process requires fast deceleration, an external brake module must be integrated via the DC bus.

Is a Local Control Panel (LCP) required for configuration?

This unit is supplied without an LCP or blind cover. Commissioning and parameter monitoring are intended to be performed using an external LCP or via serial communication through the control card.

How does the conformal coating improve durability in chemical processing plants?

The conformal coating creates a physical barrier against corrosive gases and airborne pollutants, preventing short circuits and trace oxidation on the circuit board that typically cause failures in aggressive industrial climates.

Installation and Operational Guidelines

• Heat Management and Clearance: Given the 30 kW capacity, this drive generates significant thermal energy. It is mandatory to install the unit in an enclosure with filtered forced-air cooling. Maintain at least 200 mm of clearance above and below the drive to ensure the internal cooling fans can circulate air effectively through the heatsink.
• Grounding Requirements: To ensure compliance with RFI Class A2 standards and protect the internal sensitive electronics, the drive chassis must be connected to a high-integrity industrial earth. Use a short, low-impedance ground cable and ensure the motor cable shield is terminated directly to the drive frame using a 360-degree conductive clamp.
• Safety and Discharge Time: Due to the large capacitance in the 30 kW frame size, always wait at least 15 minutes after disconnecting the mains power before performing any internal maintenance or terminal adjustments. Always verify that the DC bus voltage has dropped to a safe level (under 50 VDC) before proceeding.
