4. KEY FEATURES

• High torque density: Long stack (44E) delivers high continuous torque in a compact 84 mm flange.

• E‑winding: Optimized for 400/480 VAC mains and 320–640 VDC bus systems.

• Integrated 24 VDC brake: Ideal for vertical axes, holding torque ≥8 Nm.

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

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

• Brushless design: Low maintenance, long service life, high efficiency.

• PTC thermal protection: Prevents overheating in stator windings.

5. APPLICATIONS

• High‑torque positioning systems

• Vertical motion axes (with brake)

• CNC machines, milling/turning centers

• Packaging, material handling, robotics

• 400/480 VAC industrial automation systems

6. COMPATIBLE DRIVES

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

7. INSTALLATION & WIRING (SUMMARY)

Mounting

• Use a clean, flat, rigid mounting surface.

• Secure with 4×M8 screws; torque to 12–14 Nm.

• Align shaft coupling carefully to avoid radial/axial overloads.

• Ensure adequate cooling airflow around the motor.

Wiring

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

• Brake: Separate 24 VDC supply; brake engages when power is removed.

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

8. MAINTENANCE

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

• Seals: Inspect periodically to maintain IP65 rating.

• Connectors: Check for tightness, corrosion, or moisture; keep connectors dry.

• Brake: Test holding torque annually; adjust or replace if necessary.

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

9. SAFETY NOTES

• Disconnect all power (motor, brake, control) before installation or maintenance; motor remains live briefly after stop.

• Ground motor housing properly to avoid electric shock.

• Do not exceed max speed (5,000 rpm) or peak torque (~20 Nm); risk of damage or injury.

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

• For vertical axes, ensure brake power is fail‑safe (brake engages on power loss).
