4. Installation Instructions

  1. Cut off all power of machine tool and servo system before installation and maintenance.

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

  3. Align the motor flange with the mechanical mounting surface, fix with standard bolts and tighten evenly to ensure mounting flatness and concentricity.

  4. Install coupling or transmission components strictly ensuring coaxiality between motor shaft and load shaft to avoid eccentric vibration and abnormal wear.

  5. Connect motor power cable and encoder cable strictly according to official wiring specifications and pin definitions.

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

  7. Recheck all mechanical fastening bolts and wiring connections to ensure firm installation and correct connection.

  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, demagnetization and burnout.

  2. Avoid frequent rapid forward and reverse jogging for a long time to reduce overcurrent impact and thermal overload.

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

  4. Keep reliable grounding for motor and equipment to prevent electric leakage and electromagnetic interference affecting positioning accuracy.

  5. Do not disassemble motor shell, internal encoder and rotor structure without professional authorization.

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

  7. Do not apply external heavy impact or pressure on the motor shaft to prevent shaft deformation and internal encoder damage.

6. Maintenance and Storage

  1. Regularly clean dust and oil stains on the motor surface, keep heat dissipation area clean and unobstructed.

  2. Periodically check mounting bolts, mechanical connectors and cable terminals for looseness, tighten in time if loose.

  3. Store in dry, ventilated, dust-free indoor environment without corrosive gas.

  4. Storage temperature: 5℃ ~ 35℃, relative humidity ≤ 85%, keep non-condensing.

  5. Avoid collision, extrusion, dropping and long-term axial pressure during handling and storage.

  6. Shelf life: 12 months under original sealed packaging and standard storage conditions.
