Kollmorgen S700 Series: Comprehensive Module Range and Technical Overview

The Kollmorgen S700 series is a high-performance digital servo drive platform deployed across global heavy industry sectors including chemical processing plants, nuclear power facilities, oil refineries, steel mills, and precision manufacturing lines. Rated for single- and three-phase AC input from 120V to 480V, the S700 family covers output current ranges from 3A to 700A continuous, making it one of the most scalable servo drive architectures in the motion control market. Its installed base spans OEM machine builders, process automation integrators, and long-cycle industrial facilities that require decades of operational continuity from a single drive platform.

The S700 is engineered around Kollmorgen's AKD-compatible motion kernel and supports SynqNet, CANopen, PROFIBUS-DP, EtherCAT, and DeviceNet fieldbus protocols, enabling direct integration into Siemens, Rockwell, Beckhoff, and Schneider DCS/PLC architectures without gateway hardware. The drive's modular I/O expansion and dual-port Ethernet topology make it a reference design for multi-axis coordinated motion in continuous process environments.

The Evolution of S700 Architecture

The S700 platform was introduced as the successor to Kollmorgen's S600 series, inheriting the same 24VDC logic supply architecture while transitioning from analog command interfaces to fully digital fieldbus control. Early S700 variants (circa 2000–2005) used a proprietary SynqNet ring topology for multi-axis synchronization, which remains in active use in legacy semiconductor and packaging machinery.

Between 2006 and 2012, Kollmorgen expanded the S700 with EtherCAT and CANopen variants, aligning the platform with IEC 61800-7 (CiA 402) motion profiles. This generation introduced the S71xxx and S72xxx model numbering convention, where the numeric suffix encodes the continuous output current rating and voltage class. The S71262-NANANA, for example, designates a 12A continuous / 24A peak, 230V class unit with no internal regeneration resistor and no safety option card.

From 2013 onward, Kollmorgen introduced the AKD2G as the strategic successor to the S700 for new machine designs, incorporating dual-axis capability and functional safety (STO, SS1, SLS) per IEC 62061 SIL 2. However, the S700 remains in active production and full spare parts support as of 2026, given its extensive installed base in facilities with 20+ year asset lifecycles. Compatibility between S700 and AKD2G is not direct — motor tuning files and SynqNet configurations require migration using Kollmorgen's WorkBench software.

Sourcing Hard-to-Find & Obsolete S700 Parts

DriveKNMS maintains a dedicated inventory program for the Kollmorgen S700 series, covering both current-production units and models that have transitioned to limited or end-of-life availability. For facilities operating S700 drives in long-cycle assets — refineries, power generation, chemical batch reactors — the inability to source a replacement unit within 48–72 hours can result in unplanned downtime costs that far exceed the component value.

DriveKNMS sources S700 units through a combination of authorized distributor channels, certified refurbishment pipelines, and decommissioned equipment recovery. All units sourced through recovery channels are subject to full electrical reconditioning before dispatch. For models where Kollmorgen has issued an end-of-life notice, DriveKNMS maintains buffer stock and can provide cross-reference guidance to AKD or AKD2G equivalents where a direct form-fit-function replacement is not available.

Customers requiring long-term supply agreements (LTA) for S700 spares — particularly for multi-site operations — can contact DriveKNMS to establish a managed inventory program with guaranteed lead times.

Quality Control for the S700 Range

The Kollmorgen S700 employs a high-density power stage with integrated IGBT modules, a DSP-based current control loop running at 16kHz, and a backplane-style I/O connector system that is sensitive to mechanical stress and contamination. DriveKNMS applies a structured test protocol to all S700 units prior to dispatch:

• Power Stage Verification: Full load current test at rated continuous and peak current, with thermal imaging of IGBT junction temperatures under load cycle.
• Fieldbus Communication Test: CANopen, EtherCAT, or SynqNet node enumeration and cyclic data exchange verification using protocol-specific test masters.
• Encoder Interface Test: Verification of resolver, EnDat 2.1/2.2, Hiperface, and incremental encoder feedback channels using calibrated signal sources.
• Safety Function Test: For units equipped with STO option cards, IEC 62061 STO response time measurement and diagnostic coverage verification.
• Firmware Integrity Check: Confirmation of factory firmware version and parameter set integrity using Kollmorgen WorkBench software.
• Mechanical Inspection: Connector pin condition, heatsink integrity, fan operation (where applicable), and enclosure seal assessment.

Test records are retained per unit serial number and are available to customers on request.
