Kollmorgen MMC-SD-6.0-460-D
Product Introduction: The MMC Smart Drive family are compact, standalone digital AC servo/vector drives with onboard motion controller capability. The MMC-SD-6.0-460 delivers 6.0 kW continuous at 460 V AC input and is typically used with larger AKM5x/AKM6x motors or Goldline BH/MH series. The “–D” suffix commonly indicates DeviceNet communications or a specific I/O/feedback configuration in the MMC legacy range.

-
Weight: ≈ 16 lb (7.3 kg)
-
Recommended Input Fuse: ≤ 41 A time-delay
-
Recommended Line Reactor: Yes (per manual, for optimum performance and harmonic reduction)
-
-
Features: Non-volatile parameter storage; software oscilloscope; autotune; separate control & line power for diagnostics when line is off; supports up to multi-axis coordination via network or standalone program execution.
-
Applications: Large packaging machines, converting lines, coil winding, web handling — especially in legacy systems originally specified with MMC platform.
-
Installation & Cautions: Requires 3-phase supply with proper grounding; install line reactor per manual; connect shield at drive end; verify motor and feedback type in PicPro before enabling; this is a legacy product — Kollmorgen now recommends AKD or AKD2G for new designs. External shunt resistor may be required for high regeneration applications.
