6. Installation and Maintenance

Installation

Confirm the fixed plane of the chassis and secure the motor with bolts.
Align the axial center and connect using a standard coupling.
Connect to the three-phase power supply according to the electrical wiring diagram, and ensure the terminal blocks are tightly fastened.
Check that the protective cover and sealing ring are intact to prevent dust from entering.

Commissioning

Perform auto-tuning via the Lenze inverter and record the starting current and torque.
Check whether the speed and torque meet the rated parameters.

Daily Maintenance

Inspect the bearing lubricating oil or grease every 6 months and replace if necessary.
Regularly clean the heat sinks and end covers to prevent dust accumulation.
Monitor the operating temperature and current, and stop the machine for inspection in case of abnormalities.

Troubleshooting

Overheating: Check if the air vents are blocked and if the bearing lubrication is insufficient.
Abnormal Noise: Check for bearing wear or rotor imbalance.
Abnormal Current: Verify the power supply voltage, correct wiring, and reasonable inverter parameter settings.
