134F2974 Danfoss VLT AutomationDrive FC 360 1.5 kW

Product Overview

The 134F2974 (134F2974) is a compact and efficient VLT AutomationDrive FC 360 frequency converter designed for versatile motor control in industrial automation. Rated at 1.5 kW (2.0 HP) with a high overload (H) capacity, this drive is specifically engineered to handle applications requiring high starting torque, such as small conveyors, mixers, and packaging machinery. The 134F2974 features coated PCBs for enhanced durability in harsh environments and an integrated brake chopper for managing regenerative energy during rapid deceleration. Its IP20 chassis design is optimized for space-saving installation within control cabinets, providing a reliable and cost-effective solution for precision speed and torque control.

Technical Specifications

Technical FAQs

Can the 134F2974 be used in high-vibration or corrosive environments?

Yes. The "C" suffix indicates that the printed circuit boards (PCBs) are coated according to Class 3C3 standards. This provides essential protection against moisture, dust, and corrosive gases, which is vital for the longevity of the drive in industrial process environments.

How does the integrated Brake Chopper function in this 1.5 kW drive?

The brake chopper (B suffix) allows the drive to be connected directly to an external braking resistor. This is critical for applications where the motor must stop quickly or holds a descending load, as it allows the drive to dissipate excess energy as heat rather than tripping on a DC-link overvoltage fault.

Is a control panel required for the initial setup of this drive?

The "X" suffix means this unit is shipped without a display. For commissioning, you will need to either plug in a temporary Local Control Panel (LCP) or connect the drive to a PC via the USB port using the Danfoss VLT Motion Control Tool MCT 10 software.

Engineering & Installation Guide

• Side-by-Side Mounting: The FC 360 series is designed for "true" side-by-side mounting. You can install multiple 134F2974 units directly next to each other without horizontal clearance, provided that the cabinet's forced ventilation is sufficient to handle the combined thermal load.

• Loadsharing and DC Bus Wiring: The "D" option allows for loadsharing. If connecting several drives via the DC bus, ensure that the cabling is sized correctly for the DC link current and that appropriate DC fuses are installed between the units to prevent damage during a hardware fault.

• EMI and Shielding: To comply with RFI Class A2 standards, use only shielded motor cables. The shield must be connected to the metal decoupling plate of the drive with 360-degree contact. Ensure that control wiring (RS485 or I/O) is physically separated from power and motor cables to prevent signal interference.
