4. KEY FEATURES

• Ultra‑high torque density: Size 6 + stack 5 delivers 25 Nm stall torque in a 138 mm flange.

• M‑winding: Optimized for 400/480 VAC and 640 VDC buses, 5.69 kW rated power.

• Heavy‑duty 24 VDC brake: 32 Nm holding torque for large vertical axes.

• Resolver feedback: No electronics, extreme EMI immunity, high shock/vibration resistance.

• IP65 protection: Withstands coolant, dust, and oil mist in harsh industrial environments.

• Brushless design: Zero maintenance, long life, high efficiency.

• PTC thermal protection: Prevents stator overheating.

5. APPLICATIONS

• Heavy‑duty high‑torque positioning

• Large vertical axes (cranes, elevators, gantries)

• CNC machine tools, milling/turning centers

• Extruders, mixers, conveyor systems

• 400/480 VAC high‑power automation

6. COMPATIBLE DRIVES

• Kollmorgen AKD / AKD2G series 400/480 VAC servo drives (resolver‑compatible).

7. INSTALLATION & WIRING (SUMMARY)

Mounting

• Use a rigid, flat mounting surface.

• Secure with 4×M12 screws; torque to 35–40 Nm.

• Align coupling precisely; avoid radial/axial overloads.

• Ensure unobstructed airflow for cooling.

Wiring

• Power: Shielded 3‑phase cable to M23 power connector; ground shield at drive end.

• Resolver: Shielded resolver cable to M23 feedback connector; separate from power cables.

• Brake: 24 VDC fail‑safe supply; brake engages on power loss.

• EMC: Separate motor/control cables; use shielded cables throughout.

8. MAINTENANCE

• Bearings: Lubricated for life; no re‑greasing.

• Seals: Inspect periodically to maintain IP65.

• Connectors: Check tightness and corrosion; keep dry.

• Brake: Test holding torque annually; replace if worn.

• Diagnostics: Use Kollmorgen WorkBench for monitoring and tuning.

9. SAFETY NOTES

• Disconnect all power before service; motor holds residual voltage.

• Ground motor housing properly to avoid shock.

• Do not exceed 3,000 rpm or 25 Nm stall torque.

• Brake is for holding only; do not use for dynamic stopping.

• For vertical axes, ensure brake power is fail‑safe.
