Compatible Replacement & Equivalent Models
When the original 64WKS-M240/50-RLG is unavailable or discontinued, the following models may serve as functional equivalents depending on your system configuration. Always verify electrical and mechanical compatibility before substitution.
- Kollmorgen 64WKS-M240/60-RLG — 60 Hz variant; verify input frequency compatibility
- Kollmorgen ServoStar 300 / 600 Series — Modern digital replacement with resolver support; requires parameter reconfiguration
- Kollmorgen AKD Series — Next-generation digital drive; supports resolver-to-encoder conversion modules
- Danaher Motion equivalent drives — Kollmorgen is a Danaher Motion brand; cross-reference via Danaher part catalog
- Third-party equivalents: Consult Konmask engineering team for validated cross-reference list
Why Choose the Original Model
- Drop-in compatibility: No firmware or wiring changes required for like-for-like replacement
- Resolver feedback native support: RLG suffix confirms built-in resolver loop — no external converter needed
- Proven field reliability: Widely deployed in semiconductor, packaging, and precision machining systems
- Reduced commissioning time: Original parameters and tuning values remain valid
- Spare parts availability: Konmask maintains tested surplus stock for rapid dispatch
Typical Applications
- CNC machine tool axis control (X/Y/Z servo loops)
- Semiconductor wafer handling and lithography stage drives
- Precision packaging line servo positioning
- Robotics joint actuation with resolver feedback
- Textile and printing machine web tension control
- Medical imaging equipment gantry drives
System Compatibility
- Motor compatibility: Kollmorgen Goldline, Platinum, and compatible resolver-feedback servo motors
- Controller interface: ±10 V analog command, step/direction, or serial interface (model-dependent)
- Feedback type: Resolver (RLG) — compatible with 2-pole and multi-pole resolvers
- Power supply: 240 VAC single or three-phase (verify per installation manual)
- Communication: RS-232 / RS-485 for parameter configuration
Selection Guide
Use the following criteria to confirm the 64WKS-M240/50-RLG is the correct drive for your application:
- Step 1 — Voltage & Frequency: Confirm your supply is 240 VAC / 50 Hz. For 60 Hz systems, select the -M240/60 variant.
- Step 2 — Feedback type: RLG suffix = resolver feedback. If your motor uses an encoder, select an encoder-compatible variant.
- Step 3 — Current rating: Match peak and continuous current to your motor’s nameplate data.
- Step 4 — Command interface: Verify analog ±10 V or digital command compatibility with your PLC/CNC controller.
- Step 5 — Enclosure & mounting: Confirm panel-mount dimensions and cooling requirements match your cabinet design.

Replacement & Compatibility FAQ
Q: Is the 64WKS-M240/50-RLG still in production?
A: This model is from Kollmorgen’s legacy 64WKS series. Konmask supplies tested surplus and refurbished units. Contact us for current stock status.
Q: Can I replace it with a Kollmorgen ServoStar 300?
A: The ServoStar 300 supports resolver feedback and is a common upgrade path, but requires parameter re-commissioning and possible wiring adaptation. Consult our technical team before substituting.
Q: What is the difference between the 50 Hz and 60 Hz variants?
A: The input rectifier and filter are optimized for the specified line frequency. Using a 50 Hz unit on a 60 Hz supply (or vice versa) may cause thermal or regulation issues. Always match the suffix to your supply frequency.
Q: Do you provide a test report with the unit?
A: Yes. All refurbished units ship with a functional test report. New units include OEM documentation.
Q: Can Konmask help identify the correct replacement if my original part is damaged?
A: Yes. Send us the nameplate data or photos and our engineers will recommend a validated equivalent.
