Kollmorgen MMC-S8 – 8-Axis SERCOS+ AC Servo Drive | S600 Platform
Engineering Background: The Kollmorgen MMC-S8 is a high-performance multi-axis motion controller built on the proven S600 servo platform. Designed for demanding CNC, robotics, and industrial automation environments, it leverages the SERCOS (Serial Real-time Communication System) fiber-optic ring bus to deliver deterministic, synchronized control across up to 8 servo axes.
Product Positioning: The MMC-S8 targets OEM machine builders and system integrators who require a centralized, high-throughput motion controller capable of coordinating complex multi-axis trajectories with microsecond-level synchronization. It is the preferred choice for retrofit and new-build CNC machining centers, packaging lines, and precision assembly systems.

- Scalable Architecture: Modular S600 drive modules can be added or reconfigured without replacing the MMC-S8 controller, protecting capital investment.
- Rich Feedback Compatibility: Native support for EnDat 2.2 and Hiperface DSL reduces wiring complexity and supports single-cable motor solutions.
- Proven Field Reliability: Kollmorgen S600 platform has accumulated millions of operating hours in production environments globally.
- Integrated Safety Ready: Compatible with STO (Safe Torque Off) and SS1 safety functions when paired with appropriate S600 drive modules.
System Architecture & Signal Flow
The MMC-S8 operates as the SERCOS ring master. The fiber-optic ring connects the MMC-S8 to each S600 series drive slave node in a daisy-chain topology. Each SERCOS telegram carries position commands, velocity feed-forwards, and status feedback within a single deterministic cycle. The host PLC or CNC communicates with the MMC-S8 via Ethernet (EtherNet/IP or Modbus TCP depending on firmware version) or a dedicated fieldbus interface card. Encoder feedback from each motor is processed locally at the S600 drive and reported back to the MMC-S8 via the SERCOS ring, minimizing latency and cable runs.

Technical FAQ
Q: Is the MMC-S8 compatible with SERCOS III?
A: No. The MMC-S8 uses SERCOS II / SERCOS+ (fiber-optic). SERCOS III uses Ethernet physical layer and requires a different controller. Verify your existing ring topology before ordering.
Q: Can the MMC-S8 control fewer than 8 axes?
A: Yes. The SERCOS ring can be populated with 1–8 S600 drive nodes. Unused axis slots do not require hardware.
Q: What software is required for commissioning?
A: Kollmorgen Automation Suite (KAS) or the legacy S600 WorkBench tool. Contact us for software access links included with purchase.
Q: Do you provide a test report?
A: Yes. A power-on functional test report is available upon request at time of order.
Q: What is the lead time for stock units?
A: In-stock units ship within 3–5 business days. Out-of-stock lead time is 4–8 weeks depending on sourcing channel.
