Kollmorgen AKD Series: Comprehensive Module Range and Technical Overview

The Kollmorgen AKD series represents one of the most widely deployed digital servo drive platforms in global heavy industry. Installed across petrochemical refineries, nuclear power generation facilities, offshore platforms, and large-scale chemical processing plants, the AKD platform has established a dominant position in precision motion control applications where reliability under continuous-duty cycles is non-negotiable. The series supports single-axis and multi-axis configurations and interfaces natively with all major industrial fieldbus protocols — EtherCAT, Profinet IO, CANopen, and analog/digital command — making it a standard specification in both greenfield installations and legacy system upgrades across North America, Europe, and Asia-Pacific.

The Evolution of AKD Architecture

The AKD platform was introduced by Kollmorgen as a direct successor to the S700 and SERVOSTAR 600 series, consolidating analog and digital servo control into a unified, fieldbus-agnostic architecture. Early AKD variants (circa 2009–2012) established the core hardware topology: a 24 VDC logic supply, STO (Safe Torque Off) safety function per IEC 61800-5-2, and a universal feedback interface supporting resolvers, EnDat 2.1/2.2, SinCos, and BiSS-C encoders without hardware modification.

The second-generation AKD-P (Profinet) and AKD-N (decentralized) sub-families extended the platform into distributed motion architectures, enabling direct integration with Siemens TIA Portal and Beckhoff TwinCAT environments. The AKD2G series (introduced ~2018) represents the current-generation successor, offering dual-axis control in a single housing and enhanced functional safety (SIL 2 / PLd). For installations still running first-generation AKD hardware, backward compatibility at the mechanical mounting and connector level is maintained, but firmware and parameter sets are not cross-compatible with AKD2G.

Key compatibility considerations: AKD drives require WorkBench PC software for commissioning. Drives manufactured before firmware v1.14 require a firmware update before integration with the newer AKM2G motor series. The 24 VDC auxiliary supply must remain live during E-stop sequences to preserve encoder position data.

Sourcing Hard-to-Find & Obsolete AKD Parts

The first-generation AKD series (pre-2018 manufacture dates) has entered the mature/end-of-production phase. Kollmorgen has transitioned primary development resources to the AKD2G platform. As a result, certain AKD variants — particularly low-current single-phase models and specialized communication variants — are no longer available through standard distribution channels.

DriveKNMS maintains a dedicated inventory of tested, pull-from-service, and new-surplus AKD units to support lifecycle extension for installed bases. Our sourcing network covers North America, EU, and Asia-Pacific secondary markets. For OEM-discontinued part numbers, we provide cross-reference analysis to identify functional equivalents within the AKD family or migration paths to AKD2G where applicable. All units are supplied with full traceability documentation. Lead times for hard-to-find variants are typically 3–10 business days depending on current stock position.

Quality Control for the AKD Range

AKD drives incorporate a multi-layer internal architecture: DSP-based current loop control, FPGA-managed feedback processing, and a dedicated safety controller for STO function. Each unit processed by DriveKNMS undergoes a structured test protocol prior to dispatch:

1. Visual inspection of power stage, gate driver board, and capacitor bank for physical damage or electrolytic degradation.
2. Auxiliary 24 VDC power-up sequence with firmware version verification via WorkBench software.
3. DC bus charge/discharge cycle test to validate pre-charge resistor and bus capacitor integrity.
4. STO channel functional test per IEC 61800-5-2 (both STO1 and STO2 channels independently verified).
5. Feedback interface test across resolver and EnDat channels using reference encoder simulator.
6. Fieldbus communication test (EtherCAT/Profinet) with live network frame exchange and node address verification.
7. Full load simulation at rated continuous current for thermal stability confirmation.

Test records are retained and available upon request for quality-critical applications in regulated industries.
