4. KEY FEATURES

• Medium inertia, high dynamic response: Balanced for acceleration and smoothness.

• High torque density: Compact 58 mm flange with 0.68 Nm continuous torque.

• ComCoder encoder: 2000 ppr + Hall signals; no battery, high noise immunity.

• Integrated 24 VDC brake: Safe holding for vertical axes (spring‑applied).

• IP65 protection: Suitable for dust/wet industrial environments.

• Brushless design: Low maintenance, long service life.

• Thermistor protection: PTC thermistors in stator windings for overheat protection.

5. APPLICATIONS

• High‑dynamic positioning systems

• Packaging, printing, textile machinery

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

• Vertical motion axes requiring holding brake

• 230 VAC / 320–640 VDC industrial automation systems

6. COMPATIBLE DRIVES

• Kollmorgen AKD / AKD2G series servo drives (230 VAC / 640 VDC variants).

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

• Feedback: ComCoder cable to M23 encoder connector; no battery required.

• Brake: 24 VDC ±10%; apply voltage to release brake; wire for safe vertical loads.

• EMC: Separate power/feedback 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 stall torque (0.84 Nm); risk of damage/injury.

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

• For vertical axes, add external mechanical brake for functional safety.
