Kollmorgen AKD Series: Comprehensive Module Range and Technical Overview

The Kollmorgen AKD series represents one of the most widely deployed servo drive platforms in global heavy industry. Installed across petrochemical refineries, nuclear power auxiliary systems, offshore drilling rigs, automotive body-in-white lines, and precision packaging machinery, the AKD platform has established a dominant position in motion control applications requiring deterministic torque response, high dynamic stiffness, and multi-protocol fieldbus integration. Its compact DIN-rail and panel-mount form factors, combined with a unified software environment (WorkBench), have made it the reference architecture for machine builders across North America, Europe, and Asia-Pacific since its commercial introduction in 2010.

The AKD series is engineered to operate with Kollmorgen's AKM, CDDR, and TBM motor families, and supports resolver, SFD (Smart Feedback Device), EnDat 2.2, BiSS-C, and incremental encoder feedback natively. Continuous output current ratings span from 3 A to 96 A (peak to 144 A), covering servo axes from sub-kilowatt positioning stages to multi-kilowatt industrial robots.

The Evolution of AKD Architecture

The AKD platform was introduced in 2010 as a successor to the Kollmorgen S700 and Servostar 600 series, consolidating analog, CANopen, EtherCAT, PROFINET, and EtherNet/IP variants under a single hardware chassis differentiated only by the communication option card installed at the factory. This modular communication architecture — encoded in the drive's part number at the 5th field (e.g., NBCC = EtherCAT, NAAN = Analog/RS232, NACC = CANopen) — allowed OEMs to standardize mechanical design while selecting fieldbus topology per end-user requirement.

Between 2012 and 2016, Kollmorgen introduced the AKD2G (second-generation) sub-family, adding dual-axis capability, functional safety (STO, SS1, SLS per IEC 62061 / ISO 13849), and expanded Safe Motion options. The original AKD (single-axis) line entered a mature/sustaining phase circa 2018, with Kollmorgen committing to spare parts availability through at least 2028 under its lifecycle policy. End-users operating legacy AKD installations in continuous-process industries (refineries, power generation) must plan for long-term spare parts inventory, as lead times for factory-new units have extended to 16–26 weeks in post-2022 supply conditions.

Compatibility note: AKD drives are not backward-compatible with Servostar 600 or S700 parameter files. WorkBench software version must match drive firmware generation; mixing firmware 1.x and 2.x parameter sets causes initialization faults (F501, F502).

Sourcing Hard-to-Find & Obsolete AKD Parts

DriveKNMS maintains a dedicated inventory program for AKD series units that have been discontinued, are subject to extended factory lead times, or are required as emergency replacements in continuous-process facilities where unplanned downtime carries significant financial and safety consequences.

Our sourcing protocol for AKD spare parts includes: verification of manufacture date code and firmware revision against the customer's installed base; cross-referencing of communication option card variant (NAAN / NACC / NBCC / NBEC / NBFC) to confirm drop-in compatibility; and inspection of the DC bus capacitor bank condition for units sourced from secondary market channels. For customers operating AKD drives installed prior to 2015, we recommend proactive replacement of the internal fan assembly (Kollmorgen service part 804-00-0001) and DC bus capacitors as part of a scheduled maintenance interval.

DriveKNMS stocks or can source the following AKD-adjacent components: AKD-PDMM (drive-based multi-axis motion controller), AKD-N (decentralized servo drive for direct motor mounting), external regenerative resistor assemblies, and WorkBench software license media for offline commissioning environments.

Quality Control for the AKD Range

Each AKD unit processed by DriveKNMS undergoes a structured inspection and functional test sequence designed around the specific failure modes documented in Kollmorgen's field service bulletins for this platform.

Stage 1 — Visual and Mechanical Inspection: examination of the power connector block (X8) for arc tracking or thermal discoloration; inspection of the feedback connector (X10) for bent pins; verification of the communication option card seating and locking tab integrity.

Stage 2 — Power-On and Firmware Verification: controlled energization at reduced DC bus voltage using a variac; confirmation of drive firmware version via WorkBench service connection; verification that the drive initializes to the correct operational mode (position, velocity, or torque) without fault codes F001–F999.

Stage 3 — Dynamic Load Test: the drive is connected to a matched AKM motor on a dynamometer test bench and commanded through a standardized velocity profile (0–3000 RPM ramp, hold, reverse) to verify current loop bandwidth, encoder feedback integrity, and thermal performance at rated continuous current.

Stage 4 — Communication Bus Test: for fieldbus variants (EtherCAT, EtherNet/IP, PROFINET), the drive is connected to the corresponding master controller and verified for correct PDO mapping, synchronization, and fault response behavior.

All test results are documented and available to the customer upon request.
