Kollmorgen SERVOSTAR 600 Series: Comprehensive Module Range and Technical Overview

The Kollmorgen SERVOSTAR 600 series is a family of digital servo amplifiers deployed across global heavy industry sectors including chemical processing plants, nuclear power facilities, oil refineries, and precision manufacturing lines. The SERVOSTAR 601 is the 1 A continuous-output variant of this platform, designed for compact, high-precision axis control in multi-axis machine architectures. The series operates on a unified firmware and parameter base, enabling standardized commissioning across mixed-axis installations. Its installed base spans OEM machine builders in Europe, North America, and Asia-Pacific, with active units still running in facilities with 15+ year operational cycles.

The Evolution of SERVOSTAR 600 Architecture

The SERVOSTAR 600 platform succeeded the earlier SERVOSTAR 300 and SERVOSTAR CD analog-era amplifiers, introducing full digital closed-loop control via the proprietary SERCOS II and CANopen fieldbus interfaces. Early production units (pre-2005) used a discrete IGBT gate driver architecture with external EMC filters; post-2008 revisions integrated EMC filtering on-board and introduced the SynqNet motion bus option. The series supports resolver, SinCos encoder, EnDat 2.1/2.2, and Hiperface feedback devices, making it compatible with the full Kollmorgen AKM and RBE motor families as well as third-party servomotors. Firmware versions S600-V6.x introduced auto-tuning and advanced notch filter algorithms. The SERVOSTAR 600 series reached end-of-active-production status; Kollmorgen's current replacement platform is the AKD2G series, though direct drop-in replacement requires mechanical and electrical adaptation. Long-term spare parts and repair support for SERVOSTAR 600 units remains commercially active through specialist distributors.

Sourcing Hard-to-Find & Obsolete SERVOSTAR 600 Parts

DriveKNMS maintains a dedicated inventory program for end-of-life and hard-to-source SERVOSTAR 600 series units. As the series has entered its mature/declining lifecycle phase, OEM production of new units has ceased. DriveKNMS sources verified surplus stock, factory-refurbished units, and tested used modules from decommissioned installations globally. All units are cross-referenced against Kollmorgen part number databases to confirm series authenticity. For facilities operating legacy SERVOSTAR 600 installations where full system replacement is not economically viable, DriveKNMS provides a lifecycle extension service: sourcing specific current-rating variants, communication interface versions, and firmware-matched units to maintain operational continuity without full drive system redesign. Customers requiring multiple units for a multi-axis machine should submit a complete axis list for consolidated sourcing.

Quality Control for the SERVOSTAR 600 Range

Each SERVOSTAR 600 unit processed by DriveKNMS undergoes a structured inspection and functional test protocol. Visual inspection covers the power stage IGBT module, DC bus capacitor bank, gate driver PCB, and feedback interface connector integrity. Functional testing is performed on a dedicated servo drive test bench: the unit is powered at rated input voltage, loaded against a calibrated motor-load simulator, and exercised through velocity, torque, and position control modes. SERCOS and CANopen communication variants are tested for correct node addressing, PDO mapping, and cyclic data exchange. Firmware version is verified and documented. Units exhibiting parameter corruption are reflashed to the last stable firmware revision compatible with the hardware revision. A test report is issued with each unit shipped.
