Product Instruction Manual Part Number: A06B-0115-B503#0100 English Version (No Images) 1. Product Overview 1.1 Product Type FANUC AC Servo Motor with Power-off Holding Brake 1.2 Part Number Code Explanation A06B: FANUC servo motor and spindle motor series code 0115: Basic motor model, defines frame size, power grade and low-inertia rotor structure B503: Built-in DC power-off brake, keyed shaft, flange mounting and encoder configuration #0100: Special factory customized version, dedicated voltage, speed and system matching parameter code 1.3 Product Description A06B-0115-B503#0100 is a low-inertia high-performance AC servo motor with integrated power-off brake, designed for FANUC CNC system and industrial automation equipment. It adopts high-efficiency magnetic circuit and low-inertia rotor design, featuring fast acceleration & deceleration, high torque density and smooth low-speed running. The internal power-off brake instantly locks the motor shaft when power is disconnected, effectively preventing vertical or inclined axis sliding, ensuring mechanical position holding and equipment safety. The #0100 version is factory optimized for specific voltage and speed parameters, fully compatible with matching FANUC drives for plug-and-play replacement. 1.4 Application Scope Suitable for CNC machining centers, vertical machine tools, CNC lathes, grinding machines, drilling and tapping machines, industrial robot joint axes and automated production lines. Especially ideal for vertical feed axes and mechanical structures requiring anti-drop holding brake function.

4. Installation Instructions

  1. Cut off the total power supply of machine tool and servo system before installation and maintenance.

  2. Inspect motor appearance, flange surface, shaft and keyway for damage, deformation or rust.

  3. Fix the motor on mechanical mounting surface with standard bolts, tighten evenly to ensure mounting flatness.

  4. Install the coupling strictly controlling coaxiality between motor shaft and load shaft to reduce vibration and abnormal wear.

  5. Connect motor power cable, encoder cable and brake cable strictly according to wiring specifications.

  6. Arrange cables reasonably, avoid sharp bending, heavy extrusion and crossing with high-voltage lines.

  7. After installation, recheck all mechanical fastening and wiring connections.

  8. Power on the system, complete servo initialization, origin calibration and no-load test operation.

5. Operation Precautions

  1. Do not operate beyond rated voltage, speed and load range to prevent motor overheating and burnout.

  2. Avoid frequent forward and reverse jogging in a short time to reduce overcurrent impact and thermal overload.

  3. Do not use in environments with heavy dust, oil mist, corrosive gas and water splash.

  4. Keep reliable equipment grounding to prevent electric leakage and electromagnetic interference.

  5. Do not disassemble motor, brake assembly and internal encoder without professional authorization.

  6. Stop operation and cut off power immediately if abnormal noise, vibration, overheating or shaft slipping occurs.

6. Maintenance and Storage

Clean motor surface dust and oil stains regularly, keep heat dissipation surface unobstructed.
Periodically check mounting bolts, coupling tightness and cable connector looseness.
Regularly test brake holding performance to confirm no slipping after power off.
Store in dry, ventilated, dust-free indoor environment without corrosive gas.
Storage temperature: 5℃ ~ 35℃, relative humidity ≤ 85%, keep non-condensing.
