Interface and Communication Configuration

• Power Interface: Top‑mounted junction box for U/V/W three‑phase power and PE protective ground.

• Feedback Interface: Dedicated resolver connector for position, commutation, and speed signals; no external electronics in the motor for enhanced durability.

• Mechanical Interface: IEC metric flange with keyway shaft (shaft diameter 31.75 mm) for direct load connection.

• Drive Compatibility: Fully compatible with Allen‑Bradley 1394, Ultra, and Kinetix series servo drives; all control and communication are processed via the matched drive, with no independent communication port on the motor.

• Anti‑Interference Design: Shielded cables and sealed connectors to withstand complex industrial electromagnetic environments.

Core Functions

• High Power and Torque Output: 9.6 kW continuous power and 39 N·m stall torque support heavy loads and frequent start‑stop cycles.

• IP67 Harsh Environment Protection: Sealed housing resists dust, water immersion, and moisture, suitable for wet or dirty workshops.

• Precise and Stable Feedback: Brushless resolver provides accurate, long‑term signal feedback with excellent vibration and temperature resistance.

• Smooth Low‑Speed Operation: Three‑phase sinusoidal winding minimizes torque ripple for consistent performance at low speeds.

• Overheating Protection: Built‑in normally closed thermal switch (115 VAC/24 VDC, 1 A) triggers automatic shutdown to protect windings from damage.

• Rugged Mechanical Structure: Precision‑balanced rotor (0.0127 mm peak‑peak displacement) reduces vibration and noise during operation.

Application Scenarios

• Heavy‑Duty CNC Machine Tools: Lathes, milling machines, grinders, and machining centers requiring high torque and precision.

• Metal Forming Equipment: Stamping, bending, and forging machines with high‑load and impact‑resistance requirements.

• Automated Production Lines: High‑speed material handling, assembly, and packaging machinery in dusty or humid environments.

• Automotive Manufacturing: Welding stations, painting lines, and conveyor systems needing reliable motion control.

• Legacy System Replacement: Ideal for renovating or maintaining older Allen‑Bradley servo systems, especially in harsh factories where IP67 protection is critical.

Usage and Maintenance Instructions

Usage

• Installation: Mount the motor on a rigid base with sufficient heat dissipation space; use flexible couplings to avoid shaft misalignment.

• Wiring: Connect power and feedback cables strictly per terminal definitions, ensuring reliable grounding; use shielded cables for feedback signals.

• Drive Setup: Configure parameters on the matched Allen‑Bradley drive per motor specifications.

• Commissioning: Perform a jog test to verify rotation direction before formal operation.

Maintenance

• Regular Inspection: Check housing, flange, cables, and connectors for damage every 3–6 months.

• Cleaning: Disconnect power before wiping the motor and junction box with a dry cloth; avoid water or chemical cleaners.

• Terminal Tightening: Retighten wiring terminals annually to prevent loose connections.

• Feedback Check: Inspect resolver connectors and signal lines regularly to ensure stable feedback.

• Bearing Maintenance: Sealed bearings require no regular lubrication; replace bearings if abnormal noise or vibration occurs.

• Storage: Keep spare motors in a cool, dry, dust‑free environment; do not disassemble without professional guidance.
