In a significant expansion of its motion control portfolio, Beckhoff Automation has unveiled the AF1000 variable frequency drive (VFD), a new solution specifically engineered to address the growing demand for cost-effective and highly integrated control in basic drive applications. This introduction marks a strategic move by Beckhoff to extend its renowned PC-based control philosophy and EtherCAT ecosystem to a broader spectrum of industrial tasks, offering a unified platform from high-performance servo control to fundamental motor regulation. The AF1000 is designed for applications such as conveyor systems, pumps, and fans, integrating seamlessly with the overarching TwinCAT automation system through EtherCAT, and crucially, incorporating the same advanced commissioning and diagnostic functions found in Beckhoff’s more sophisticated servo drive products.
A Unified Approach to Drive Technology: The AF1000’s Core Offering
The AF1000 represents Beckhoff’s commitment to providing scalable and holistic automation solutions. By integrating the new VFD into the TwinCAT environment via EtherCAT, the company ensures that users can manage diverse motion control needs—from complex multi-axis synchronization to simple speed and torque regulation—within a single, familiar software interface. This approach not only streamlines engineering workflows but also reduces the learning curve for operators already proficient in Beckhoff systems, fostering efficiency and consistency across an entire plant.
The drive’s design focuses on practical functionality and robust performance for its target applications. Variable frequency drives are essential components in modern industrial operations, primarily responsible for controlling the speed and torque of AC motors by varying the frequency and voltage of their power supply. This capability translates directly into significant energy savings, improved process control, reduced mechanical stress on equipment, and enhanced operational flexibility. For basic applications like those targeted by the AF1000, these benefits are paramount, contributing to lower operating costs and increased equipment longevity.
Technical Specifications and Versatility
The AF1000 is offered in two distinct versions, catering to different power supply configurations and application demands. The first version is designed for single-phase 240 V AC supply, providing a power range from 0.37 kW to 1.5 kW. This variant is particularly suitable for smaller-scale operations or regions where single-phase industrial power is more prevalent. The second, more powerful version, accommodates a three-phase supply up to 480 V AC, with a broader power range spanning from 0.37 kW up to 5.5 kW. This three-phase option is ideal for more demanding industrial environments and larger equipment where higher power output is required.
Both versions boast an impressive array of integrated components, signifying a compact and efficient design. These include an integrated control power supply, DC link capacitors, and a ballast circuit. The integrated control power supply is a crucial feature, eliminating the need for an external power source for the drive’s internal electronics. Instead, the control voltage is generated directly from the DC link, which is the rectified intermediate circuit voltage derived from the main power supply. DC link capacitors play a vital role in smoothing the DC voltage and storing energy, providing stability during transient load changes and enhancing the drive’s overall robustness. The inclusion of a ballast circuit, also known as a braking chopper or braking resistor, is particularly noteworthy. This component is designed to dissipate excess regenerative energy generated by the motor during deceleration, preventing overvoltage conditions in the DC link and allowing for controlled braking, thereby extending the life of the drive and connected machinery.
Further enhancing its versatility, the AF1000 is available as either a single-axis module or a two-axis module. The two-axis configuration offers a compact and cost-effective solution for controlling two independent motors from a single drive unit, which can be particularly advantageous in applications like multi-stage conveyor systems or synchronized pump operations. The drive supports a wide range of motor types without requiring feedback encoders, simplifying installation and reducing overall system cost. These include synchronous servomotors, asynchronous motors, and reluctance motors. The flexibility to operate these motors in either UF (Volts per Hertz) mode or with sensorless vector control allows users to choose the optimal control strategy based on their application’s precision and dynamic requirements. UF mode is typically simpler and suitable for applications where precise speed regulation under varying loads is not critical, while vector control offers better dynamic response and speed accuracy, even without a motor encoder.
The TwinCAT Advantage: Simplified Commissioning and Diagnostics
A cornerstone of Beckhoff’s automation philosophy is the TwinCAT software suite, which serves as the central engineering and runtime environment for all its control components. The AF1000 drive is commissioned using TwinCAT Drive Manager 2, the identical engineering tool utilized for Beckhoff’s high-performance servo drives. This commonality provides a significant advantage for users, as it eliminates the need to learn new software tools or adapt to different programming paradigms when integrating basic VFDs alongside more complex motion control solutions.
