4. Mechanical Construction
The motor adopts a heavy-duty cast housing with flange mounting interface for rigid installation. The output shaft is a straight shaft without keyway, designed for direct coupling connection. An external cooling fan is mounted on the rear end cover to ensure stable temperature during continuous high-load operation. The motor structure is rugged to withstand vibration and shock in industrial environments.
5. Environmental Conditions
Operating Temperature: 0 °C to 40 °C
Storage Temperature: -20 °C to 60 °C
Relative Humidity: 40% to 80%, non-condensing
Altitude: Up to 1000 m above sea level; derating required for higher altitudes
Vibration: 0.5 g maximum during operation
Atmosphere: Clean air, free from corrosive gases and excessive dust
6. Safety Instructions
Only qualified electrical and mechanical technicians are allowed to perform installation, wiring, commissioning, and maintenance. Disconnect all power supplies before any work to avoid electric shock. The motor is heavy; use proper lifting equipment during handling and installation. Do not exceed rated voltage, current, speed, or torque. The cooling fan must operate normally during continuous running. Do not disassemble the motor or encoder without authorization.
7. Installation and Wiring
Install the motor on a flat, rigid mounting surface. Align the shaft accurately when installing couplings to avoid excessive radial or angular misalignment. Secure all mounting bolts with specified torque. Connect power cables, encoder cables, and fan power cables according to FANUC standard wiring diagrams. Separate encoder signal cables from high-power cables to reduce electromagnetic interference. Ensure reliable grounding for both motor and drive.
8. Operation and Commissioning
After installation and wiring, verify all connections before power-on. Set servo drive parameters corresponding to motor model A06B-0158-B075#7008. Perform low-speed test operation to check for abnormal noise, vibration, or temperature rise. Gradually increase speed up to rated 2000 rpm. Monitor current, temperature, and vibration during normal operation. The cooling fan must run continuously during high-duty operation.
9. Maintenance
Regularly check cable connections for tightness and signs of aging. Keep the motor surface and fan clean from dust and debris. Inspect fan operation periodically. Check bearing noise and temperature periodically. Do not lubricate bearings unless specified by FANUC. If the motor is stored for a long period, keep it in a dry, non-condensing environment. All internal repairs must be performed by FANUC-authorized service personnel.
