134F2972 Danfoss VLT AutomationDrive FC 360 0.75kW VFD

Product Overview

The 134F2972 (134F2972) is a high-performance variable frequency drive from the Danfoss VLT® AutomationDrive FC 360 series, specifically engineered for precision motor control in demanding industrial environments. Rated at 0.75 kW (1.0 hp), this drive is optimized for High Overload applications, providing the extra torque required for heavy-duty startup cycles. The 134F2972 features a robust internal architecture including Coated PCBs for protection against environmental contaminants and an integrated Brake Chopper for dynamic braking capabilities. Operating on a three-phase 380-480 VAC supply, this compact IP20 chassis-mount drive is the ideal solution for machine builders and OEMs requiring a cost-effective, reliable, and powerful motor controller for conveyor systems, packaging machines, and material handling equipment.

Technical FAQs

What are the benefits of the High Overload (H) rating for a 0.75 kW motor?

The "H" rating indicates that the 134F2972 can provide 150% to 160% of rated torque for 60 seconds. This is critical for applications like positive displacement pumps or heavily loaded conveyors that require significant breakaway torque to overcome static friction during startup.

How does the "Loadsharing" (D) option function in an industrial setup?

The Loadsharing option allows the DC-link of multiple drives to be connected. This enables energy to be shared between drives—for example, a motor that is braking can supply energy to a motor that is motoring—thereby reducing total energy consumption and heat dissipation within the control cabinet.

Can this drive be operated without a Local Control Panel (LCP)?

Yes. This specific unit is supplied without a display. It is designed to be commissioned via the Danfoss MCT 10 software through the built-in USB or RS485 port, or by utilizing a pluggable LCP 102 (Graphical) or LCP 21 (Numerical) panel which can be shared across multiple drives.

Engineering & Installation Guide

• Dynamic Braking Resistor Selection: To utilize the integrated Brake Chopper (B option), an external braking resistor must be connected to terminals R+ and R-. Ensure the resistor is sized to handle the calculated regenerative energy and is mounted in a well-ventilated area outside the drive cabinet, as it will generate significant heat during deceleration.

• Cabinet Thermal Management: Even at 0.75 kW, the drive generates heat. Maintain a minimum of 100 mm vertical clearance for the air-cooled chassis. The FC 360 supports side-by-side mounting without derating, provided the ambient cabinet temperature remains within the specified operating range (-10 to 50 deg C).

• EMC Compliance: The H2 RFI filter meets industrial Class A2 standards. To ensure compliance, use shielded motor cables and ensure the shield is grounded at the drive using the metal decoupling plate. This prevents high-frequency switching noise from interfering with nearby control sensors or PLC communication lines.
