Engineered for precision motion control applications, this drive functions as an intelligent amplifier, converting control signals from a motion controller or PLC into precisely modulated three-phase power to drive brushless servo motors. The 403M-P​ model represents a versatile and robust solution, commonly used in demanding industries like semiconductor manufacturing, electronics assembly (specifically Surface Mount Technology – SMT), packaging, and printing. It integrates a switching power supply, eliminating the need for a separate external DC bus power module in many applications, which simplifies system design and cabinet layout. The drive supports sinusoidal commutation, providing smooth, quiet, and efficient motor operation essential for high-speed, high-accuracy positioning. With its advanced digital signal processor (DSP), the Kollmorgen ServoStar 400 403M-P​ offers sophisticated control algorithms, extensive programmability, and a comprehensive suite of built-in protection features. It is designed for seamless integration with Kollmorgen’s AKM series of synchronous servo motors, creating a perfectly matched and optimized motion system. The ServoStar 400 403M-P​ is a cornerstone for machine builders who require reliable, dynamic, and precise servo control to achieve superior machine performance and throughput.

Technical Specifications

Main Features and Advantages

High performance in a compact package: The Kollmorgen ServoStar 400 403M-P​ delivers exceptional dynamic response and precision in a space-efficient design. Its integrated switching power supply allows it to connect directly to common three-phase AC mains, simplifying power distribution and reducing the component count in the control cabinet compared to drives requiring a separate DC bus supply. This integrated design, combined with a high-performance digital signal processor, enables very high switching frequencies and advanced control algorithms, resulting in exceptionally smooth motor rotation, minimal torque ripple, and superior velocity stability. This is critical for applications like precision dispensing, laser cutting, or high-speed pick-and-place where smooth motion is paramount for quality and speed.Advanced programmability and tuning: A key strength of the 403M-P​ drive is its deep programmability via Kollmorgen’s user-friendly WorkBench software. This allows for extensive customization of the drive’s behavior beyond basic tuning. Engineers can implement complex motion profiles, create custom error handling routines, and configure sophisticated sequencing logic directly within the drive, sometimes reducing the burden on the primary machine controller. The drive features advanced autotuning algorithms that quickly and accurately identify the connected motor’s and mechanical system’s parameters, automatically setting optimal PID gains for high performance and stability. The digital platform also provides extensive diagnostic and oscilloscope tools within WorkBench, enabling rapid troubleshooting and performance optimization.Seamless system integration and reliability: The ServoStar 400 403M-P​ is designed for easy integration into diverse control architectures. Its standard analog/digital I/O allows for straightforward connection to PLCs, while a wide array of optional plug-in communication modules (like SERCOS, PROFIBUS DP, or EtherCAT) enable seamless integration into high-speed networked motion control systems. The drive is built for industrial durability, featuring robust protection against electrical faults, overtemperature conditions, and supply voltage irregularities. This reliability, combined with Kollmorgen’s global support network, makes the Kollmorgen 403M-P​ a trusted choice for mission-critical automation equipment where uptime and consistent performance are essential.
