Pre-Installation: Disconnect power; ensure mounting surface is flat, clean, and rigid
Mechanical Mounting: Secure motor with 4 bolts (torque: 8–10 Nm); align shaft with load to avoid misalignment
Electrical Connection:
Power cable: Connect L1, L2, L3 to 230 VAC
Encoder cable: Connect to servo drive for position feedback
Grounding: Connect motor ground to system ground for safety
Cable Management: Secure cables to avoid tension; keep away from moving parts
Commissioning: Power on; perform servo tuning; test motion in JOG mode; verify positioning accuracy
6. Maintenance & Troubleshooting
Maintenance
Regular Inspection: Check cables, connectors, and mounting bolts monthly
Cleaning: Wipe motor surface with dry cloth; avoid water or corrosive liquids
Lubrication: Shaft bearings are pre-lubricated; no maintenance required for 20,000 hours
Overheating Check: Ensure ventilation is unobstructed; ambient temperature ≤40°C
Troubleshooting
Motor Not Running: Check power supply (230 VAC); verify encoder connection; check drive alarms
Abnormal Noise: Inspect bearing wear; check for mechanical interference
Overheating: Reduce load; check ventilation; verify voltage balance
Positioning Error: Re-tune servo parameters; check encoder wiring; verify mechanical alignment
7. Safety Precautions
Only qualified personnel should install or service the motor
Disconnect power before maintenance to prevent electric shock
Do not touch motor surface during operation (high temperature)
Avoid overloading beyond rated torque to prevent damage
Ensure proper grounding to avoid electrical hazards
