Technical Specifications

Note: Parameters above are drawn from published Kollmorgen documentation. DriveKNMS does not fabricate or estimate electrical specifications. If your application requires confirmation of a specific firmware revision or hardware variant, contact us before ordering.

Solving the Discontinued Hardware Crisis

The ServoStar 600 series was Kollmorgen's flagship digital servo drive platform for over a decade, deployed extensively in packaging machinery, semiconductor handling, medical device manufacturing, and precision CNC applications. The SERVOSTAR 603 — the 3 A continuous variant — was the workhorse of low-to-mid torque single-axis and multi-axis gantry configurations.

Kollmorgen has since transitioned its product line to the AKD and AKD2 platforms. While technically superior, these replacements are not drop-in compatible with ServoStar 600 installations. Migrating a single axis from SERVOSTAR 603 to AKD requires: new drive hardware, motor feedback cable re-termination, Workbench software re-commissioning, and in most cases, PLC motion block rewriting. For a 10-axis system, this is a multi-week engineering project.

The practical consequence: every facility still operating ServoStar 600 hardware is one drive failure away from a forced, unplanned capital project. Maintaining a tested SERVOSTAR 603 spare on the shelf converts that risk from a production emergency into a two-hour maintenance event.

How to extend your ServoStar 600 system life by 5–10 years without a platform migration:

Condition & Reliability Assurance

DriveKNMS applies a 5-step verification protocol to all obsolete servo drive inventory before dispatch review:

1. Visual and mechanical inspection: Full external inspection for physical damage, connector pin condition, and enclosure integrity. Units with bent pins, cracked housings, or evidence of thermal events are rejected at this stage.
2. Electrolytic capacitor assessment: DC bus capacitors are tested for capacitance retention and ESR (equivalent series resistance). Capacitors showing >20% capacitance loss or elevated ESR are flagged for replacement before the unit is offered for sale.
3. Firmware version verification: The firmware revision is read and documented. This information is provided to the buyer to confirm compatibility with their existing installation.
4. Connector and pin corrosion inspection: All I/O, feedback, and power connectors are inspected under magnification. Corroded or oxidized contacts are cleaned or the unit is downgraded.
5. Functional power-up test: Where test fixtures permit, units are powered and basic drive enable/disable and fault response behavior is verified prior to shipment.

Units that pass all five stages are classified as Tested Surplus. Units that pass visual and firmware checks but cannot be fully powered are classified as Inspected Surplus and priced accordingly. Condition classification is disclosed on every order confirmation.

Key Features for System Maintenance

How do I confirm the unit is genuine Kollmorgen hardware and not a counterfeit?
All units sourced by DriveKNMS are inspected for authentic Kollmorgen labeling, correct PCB markings, and hardware revision consistency. We provide the unit's serial number and firmware revision prior to shipment so you can cross-reference against your existing installed base.
