Kollmorgen Servo System Product Guide

Kollmorgen servo system: leading integrated motion control with high precision and dynamic performance

In the fields of industrial automation and precision machinery, the performance of motion control systems directly determines the output quality, efficiency, and reliability of equipment. Kollmorgen, as a motion control expert under the Danaher Group, has built a complete, efficient, and highly integrated servo system product ecosystem with decades of technological accumulation and innovation. This article aims to provide an in-depth analysis of Colemorgen's core product line, including its iconic AKD series servo drives, AKM series servo motors, innovative direct drive technology, and diverse linear positioning and transmission solutions, demonstrating how it integrates technology to "clear design, procurement, and time barriers" for OEM manufacturers.

Core power: AKD series servo drive - high-performance control center based on Ethernet

The Kolmorgen AKD series servo drives represent the advanced level of servo drive technology today. It is not just a power amplifier, but also an intelligent control node that integrates advanced control algorithms, rich communication options, and programmable functions.

1. Excellent performance and technical features:

The core advantage of AKD drivers lies in their "second level optimization" performance. The performance servo tuner (PST) with pending patent has industry-leading automatic tuning capability, which can automatically adjust all gain parameters including the observer and respond in real-time to dynamic load changes. It can handle inertia mismatches of up to 1000:1 and accurately compensate for rigid and flexible transmission mechanisms, ensuring the system maintains optimal performance under a wide range of operating conditions.

The driver adopts a powerful dual processor system and runs leading servo algorithms, achieving extremely high bandwidth and extremely fast digital current loop response. It supports feedback devices with up to 27 bit resolution, providing unparalleled position accuracy and repeatability. Whether it is a single/multi turn absolute value encoder (such as EnDat2.2, BiSS, HIPERFACE) ®）， Whether it is a rotary transformer or an incremental encoder, AKD can be seamlessly compatible and achieve plug and play with Colmorgen motors through electronic motor nameplate function, greatly reducing debugging time.

2. Flexible architecture and scalability:

The AKD series provides a wide range of power coverage from 3A to 48A (peak current) with its compact packaging, and has extremely high power density. Its true flexibility is reflected in its scalable programmability and communication integration. From basic analog torque/speed control ("B" selection), to simple point-to-point indexing ("P" selection), to 1.5-axis drivers that support BASIC programming ("T" selection), to multi axis main control drivers with complete soft PLC functionality (such as AKD PDMM), AKD provides a smooth upgrade path.

At the communication level, AKD natively integrates multiple mainstream industrial Ethernet and fieldbus, including EtherCAT ®,  SynqNet ®,  Modbus/TCP, EtherNet/IP, PROFINET, And CANopen ®， No additional hardware tabs are required, simplifying system integration and reducing costs.

3. Humanized development and debugging tools:

The Kollmorgen WorkBench graphical user interface (GUI) greatly simplifies the process of setting up, debugging, and diagnosing drivers. Its built-in six channel real-time software oscilloscope, multifunctional Bode plot, and one click parameter sharing function enable engineers to quickly evaluate performance, diagnose problems, and collaborate for communication. This application-oriented design concept significantly reduces the threshold for use and improves development efficiency.

Accurate execution: AKM series servo motors - the source of power that combines breadth and depth

AKM frameless servo motors are the backbone of Kohlmorgen's product portfolio, renowned for their unparalleled flexibility, high power density, and outstanding performance.

1. Extensive configuration and optimized design:

The AKM series covers 8 machine base sizes from NEMA 17 (40mm) to NEMA 42 (180mm), offering up to 28 body stack combinations and nearly 120 standard windings. Its continuous locked rotor torque range extends from 0.16 Nm to 180 Nm, which can meet diverse needs from micro automation equipment to heavy industrial machinery. Through continuous optimization of the magnetic circuit and cooling system, the new generation AKM motor can provide up to 47% shaft power increase with the same base size when paired with AKD drives, while reducing the size of the drive and motor and lowering the overall system cost.

2. Support high-performance and high reliability applications:

AKM motors offer a wide range of feedback options, from high-resolution sine encoders to cost-effective intelligent feedback devices (SFDs), meeting different precision and cost requirements. The newly launched IP67 protection level option enables it to confidently be applied in harsh industrial environments such as humidity and dust. The motor itself has extremely low cogging torque, ensuring smooth low-speed operation, which is crucial for precision machining, printing, and inspection applications.
