4. KEY FEATURES

• 400/480 VAC high‑voltage winding: Optimized for 640 VDC bus systems.

• SFD single‑cable feedback: Combines power + encoder in one cable; simplifies wiring.

• Low inertia, high dynamic response: Ideal for fast cycling and precise positioning.

• IP65 protection: Suitable for industrial environments (dust, moisture).

• Brushless design: Low maintenance, long service life.

• PTC thermistor protection: Over‑temperature monitoring in stator windings.

• No brake: Reduces cost and length for horizontal‑axis applications.

5. APPLICATIONS

• High‑dynamic positioning systems

• Packaging, printing, textile machinery

• Small CNC machines, robotics, pick‑and‑place units

• Horizontal motion axes (no brake required)

• 400/480 VAC industrial automation systems

6. COMPATIBLE DRIVES

• Kollmorgen AKD / AKD2G series 400/480 VAC servo drives.

7. INSTALLATION & WIRING (SUMMARY)

Mounting

• Use a clean, flat, rigid surface.

• Secure with 4×M5 screws; torque to 4.5–5 Nm.

• Align shaft coupling to avoid radial/axial overloads.

Wiring

• Power + Feedback: SFD single cable to M23 connector; ground shield at drive end.

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

8. MAINTENANCE

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

• Seals: Inspect periodically to maintain IP65 rating.

• Connections: Check for tightness/corrosion; keep connectors dry.

• Diagnostics: Use Kollmorgen WorkBench software for fault monitoring and tuning.

9. SAFETY NOTES

• Disconnect power before installation/maintenance; motor remains live briefly after stop.

• Ground motor housing properly to avoid electric shock.

• Do not exceed max speed (8,000 rpm) or peak torque (3.84 Nm); risk of damage/injury.

• No internal brake; for vertical axes, add external brake or counterbalance.
