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, motor shaft and keyway for no damage, deformation or rust.

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

  4. Install the coupling correctly, strictly control coaxiality between motor shaft and load shaft to avoid eccentric vibration and abnormal wear.

  5. Connect power cable and encoder cable strictly according to wiring specifications, ensure firm contact and correct phase sequence.

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

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

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

5. Operation Precautions

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

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

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

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

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

  6. Stop operation and cut off power immediately once abnormal noise, vibration, overheating or servo alarm 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.
Observe motor running temperature, noise and vibration status during daily operation.
Store in dry, ventilated, dust-free indoor environment without corrosive gas.
