134F2971

The Danfoss 134F2971 drive is a member of the reliable VLT FC 360 Automation Drives series, offering robust motor control for diverse industrial applications. Designed to handle precise speed and torque requirements, this model delivers Power Rating: 0.55 kW (0.75 HP) output power through advanced voltage vector control+ (VVC+) and flux basic control algorithms. Its compact Frame Size: J1 chassis weighs just 2.64 kg, simplifying installation in confined panels while meeting IP20 enclosure requirements for dust protection. The integrated Brake Chopper: Built-in and conformal coating on the PCB ensure safe stopping and enhanced durability under normal factory conditions. With support for three-phase input voltages from Input Voltage: 380-480 VAC and a frequency range of Frequency: 50/60 Hz, this unit adapts to standard power grids without requiring special transformers.

The technical specifications of the 134F2971 control drive align with stringent automation standards. It provides a Continuous Output Current: 1.7 A (380–440 V) rating and is capable of handling a Max Pre-fuse: 10 A upstream protection device. The drive includes an RFI Filter Class: A2 to minimize electromagnetic interference per EN 55011, and offers 6 Digital Inputs alongside 2 Analog Inputs (selectable 0–10 V or 0/4–20 mA) and 2 Analog Outputs for flexible signal interfacing. Additionally, it features 2 Relay Outputs: 2 × 3 A for switching external loads. The control firmware is updatable, ensuring ongoing access to the latest features and security patches. Conformal coating on the printed circuit board enhances moisture and dust resistance, contributing to long-term reliability in industrial environments.

Operational features of the 134F2971 emphasize performance under variable load conditions. The drive supports normal overload ratings of 110% for 1 minute and high overload capability up to 160% for short-term demands, ensuring stable operation during rapid acceleration or deceleration. Smart Logic Control (SLC) enables embedded programmable logic, reducing the need for external PLCs and simplifying machine design. Position control and PID-based process control functions optimize speed and pressure regulation, improving energy efficiency and response time. The built-in voltage vector control+ algorithm maintains motor torque even at low speeds, while the advanced brake chopper safely dissipates regenerative energy during deceleration, protecting both motor and drive electronics.

System integration is streamlined through standard RS485 serial communication and configurable I/O, allowing seamless connection to higher-level SCADA and PLC systems. The unit’s compatibility with common fieldbus protocols and its compact footprint make it ideal for conveyor systems, packaging machinery, material handling, and other automation tasks. As part of the Danfoss VLT FC 360 Automation Drives family, the 134F2971 benefits from consistent parameterization and diagnostics tools, reducing commissioning time and simplifying maintenance. The result is a versatile drive solution tailored for mid-range industrial automation projects where reliability, precision, and ease of integration are critical.
