3. Product Features

1. Medium-inertia rotor: Balances dynamic response and load stability; suitable for varied inertia loads.

2. High-resolution αA64 encoder: Provides precise closed-loop positioning and speed feedback.

3. Straight keyed shaft: Ensures secure, slip-free connection to couplings/gears.

4. Compact rugged construction: High rigidity housing and bearings for long life in harsh environments.

5. Low cogging torque: Smooth low-speed performance, no crawling or jitter.

6. High efficiency: Optimized magnetic design reduces heat generation and energy consumption.

7. Standard interface: Compatible with FANUC αi-B series servo amplifiers for plug-and-play replacement.

4. Installation Instructions

1. Power safety: Disconnect all system power before installation or maintenance.

2. Inspection: Check motor housing, flange, shaft, and keyway for damage, deformation, or rust.

3. Mounting: Align motor flange with mechanical mounting surface; tighten bolts evenly to ensure flatness and concentricity.

4. Shaft connection: Install coupling/transmission components; maintain strict coaxiality to avoid vibration and premature wear.

5. Wiring: Connect 3-phase power cable and encoder cable per FANUC wiring diagrams; ensure correct pin assignment and tight connections.

6. Cable routing: Avoid sharp bends, heavy compression, or crossing with high-voltage lines; secure cables to prevent strain.

7. Grounding: Connect motor frame to system ground for electrical safety and EMC compliance.

8. Pre-operation check: Verify all fasteners and connections; perform servo initialization, homing, and no-load test run.

5. Operation Precautions

1. Do not exceed ratings: Avoid operation beyond rated voltage, speed, or torque to prevent overheating, demagnetization, or burnout.

2. Avoid frequent reversals: Minimize prolonged rapid forward/reverse jogging to reduce overcurrent and thermal stress.

3. Environment: Do not use in heavy dust, oil mist, corrosive gas, or direct water splash; maintain IP54 protection.

4. No disassembly: Do not open motor housing or tamper with encoder/rotor; this voids warranty and risks damage.

5. Abnormal conditions: Stop operation and cut power immediately if abnormal noise, vibration, overheating, or servo alarms occur.

6. Shaft protection: Do not apply heavy impact or axial load to the shaft to prevent deformation or encoder damage.

6. Maintenance and Storage

1. Regular cleaning: Wipe dust/oil from motor surface; keep cooling areas unobstructed.

2. Periodic checks: Inspect mounting bolts, couplings, and cable terminals for looseness; tighten as needed.

3. Storage: Store in dry, ventilated, dust-free indoor space (5°C–35°C, ≤85% RH, non-condensing).

4. Handling: Avoid collision, dropping, or long-term axial pressure during transport/storage.

5. Shelf life: 12 months in original sealed packaging under standard storage conditions.

7. Quality Statement

1. Compliance: This motor meets FANUC industrial manufacturing and safety standards.

2. Testing: All units undergo dynamic balance, performance, and aging tests before shipment.

3. Compatibility: This specification applies to original and compatible replacement motors of the same part number.
