Modern automation has transformed industries by streamlining processes, enhancing productivity, and minimizing errors. At the heart of this automation are servo drives, the silent conductors orchestrating the symphony of machinery. These sophisticated devices marry the worlds of electronics and mechanics, translating digital intent into precise physical motion. This article looks at servo drives, such as Kollmorgen AKD servo drives, and the role they play in enabling smooth and accurate movement in automated systems.
How do Servo Drives Work?
Firstly, servo drives receive a command signal from a control system, typically representing a desired motion or position. This command is then compared to the system’s current position, as relayed by a feedback mechanism such as an encoder. The servo drive recognizes the disparity between the desired and actual position and generates a corrective output current or voltage to the motor to initiate the necessary movement. Throughout this process, continuous feedback ensures that the motor’s position, speed, or torque is adjusted in real-time, enabling the system to maintain the desired parameters.
Evolution of Servo Drives
Decades ago, servo drives were basic entities primarily tasked with managing basic motor functions. Their main role was to provide an interface between the motor and control signals, converting those signals into the necessary power to drive the motor. The earliest versions were largely analog systems, which—while effective for their time—were limited in terms of precision and adaptability. They relied heavily on manual tunings and calibrations, making them less versatile for more complex applications.
With the advent of digital technology and microprocessors in the latter half of the 20th century, servo drives were transformed. These newer digital drives offered superior accuracy, flexibility, and ease of integration. Enhanced by software-based algorithms, they could automatically adjust and tune motor performance to meet specific application needs. This shift to digital platforms also paved the way for advanced features like programmable limit switches and more sophisticated feedback mechanisms.

What sets the Kollmorgen AKD servo drives apart? For one, their unparalleled flexibility. AKD servo drives are feature-rich and can be easily customized to suit various applications, thanks to its modular design. They are available in power ranges to suit virtually any application requirement and offer plug-and-play commissioning for instant, seamless access to your motor control system.
Kollmorgen AKD drives have the highest bandwidth torque-and-velocity loops and the fastest digital current loop in the market. They also have full-frequency, wizard-based autotuning, which intuitively adjusts settings to ensure optimal performance. Furthermore, AKD servo drives are equipped with advanced motion control algorithms that enable precise positioning and velocity control.
In today’s space-constrained environments, the AKD’s compact design is one of its highlighted advantages. Paired with Kollmorgen’s high-quality servo components, AKD drives offer industry-leading performance in a smaller and more efficient footprint. With the Kollmorgen Automation Suite™ and WorkBench platform, users can easily monitor and configure AKD servo drives for optimal performance and safety.
Applications of AKD Servo Drives
Advanced Manufacturing: As industries progressively move towards automation, the need for high-speed and precision machinery becomes paramount. Whether it is 3D printing, CNC machines carving intricate designs, or robotic arms involved in nanomanufacturing, AKD servo drives ensure the movements are precise and consistent, significantly reducing errors and enhancing production quality.
Automated Guided Vehicles (AGVs): With the surge in e-commerce and smart warehousing, AGVs play a vital role in transporting goods seamlessly within vast logistics centers. Their ability to integrate with multiple feedback devices allows these vehicles to navigate complex terrains and carry varied loads efficiently. They can help AGVs move with a level of sophistication that minimizes human intervention, driving efficiency and safety in warehouse operations.
Packaging Machinery: The dynamics of modern consumerism demand packaging processes to be both rapid and precise. Be it filling bottles, wrapping products, or labeling them, any deviation can result in wasted resources or compromised product quality. The high bandwidth and quick response times of AKD servo drives ensure that packaging manufacturers can meet their production targets while maintaining stringent quality standards.
Looking to the Future
As the march of technology continues, the future of automation is shaping up to be even more interconnected, intelligent, and efficient. The emergence of concepts such as the Internet of Things (IoT), Industry 4.0, and smart manufacturing points towards an ecosystem where machines not only perform tasks but also communicate, adapt, and make decisions based on real-time data. Processes will be optimized continuously, and downtime minimized by predictive maintenance and real-time adjustments.
Servo drives will be central to this vision. They will serve as the bridges between the digital commands of the automation system and the physical actions of machinery. The role of advanced servo drives, like those in the AKD series from Kollmorgen, becomes even more crucial in ensuring that automation is both precise and adaptable. Their ability to swiftly process feedback and make instantaneous adjustments ensures that machinery operates at peak efficiency and utmost safety.
As automation systems become more complex and demanding, the responsiveness, adaptability, and efficiency of servo drives will dictate the overall performance, reliability, and success of these systems. For industries aiming to stay at the forefront, adopting or upgrading to state-of-the-art servo drives is a clever investment that will enable them to capitalize on the full potential of automation and emerging technologies.
