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 no 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 correctly, strictly control coaxiality between motor shaft and load shaft to reduce vibration and abnormal wear.

5. Connect motor power cable, encoder cable and brake control 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, perform 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.
