Technical Specifications

Note: Electrical parameters for this obsolete assembly are not published in current documentation. Specifications are confirmed against original Kollmorgen 620 Series technical manuals during our QA process. We do not publish unverified parameters.

Solving the Discontinued Hardware Crisis

The Kollmorgen 620 Series was a workhorse of precision motion control through the 1990s and 2000s. Many facilities running this platform have made a deliberate decision to maintain rather than replace — and for sound financial reasons. The 620-AS S62001 Analog Input Assembly sits at the interface between the control system and the drive's command processing. Without a functioning replacement, the entire servo axis becomes inoperable.

For plant managers facing pressure to retire aging automation assets, the math is straightforward: a verified replacement assembly at a fraction of the cost of system migration buys 5 to 10 additional years of productive asset life. That window is sufficient to plan a controlled, budgeted migration on your schedule — not one forced by an emergency breakdown at 2 AM on a production night.

Facilities running Kollmorgen 620 Series drives alongside legacy motion controllers — including systems integrated with older Siemens SIMODRIVE environments or standalone Kollmorgen motion networks — will find this assembly directly interchangeable with the original. No architectural changes. No requalification of the broader system.

Condition & Reliability Assurance

Every Kollmorgen 620-AS S62001 unit shipped by DriveKNMS passes a structured 5-step inspection protocol developed specifically for obsolete servo drive components:

Key Features for System Maintenance

Should I buy more than one unit?
For any facility with active 620 Series axes, holding at least one cold spare is strongly recommended. This part is no longer manufactured, and secondary market availability is finite. Procurement now, during a planned cycle, is materially lower risk than emergency sourcing during a production stoppage.

Can you source additional quantity if I need multiple units?
Contact us with your quantity requirement. DriveKNMS maintains sourcing relationships across industrial surplus networks globally and can often locate additional RFQ-reviewed sourcing status beyond what is listed.
