Used in packaging machinery, electronic production assembly equipment, logistics handling automation line positioning axis. Matched for laser processing equipment, precision motion platform, testing instrument and special purpose automation machinery. Ideal for all kinds of light load, high speed, high precision and strong anti-interference required industrial motion control occasions. Installation Instructions Install the motor on a rigid and flat mounting base to avoid working resonance and shaft vibration. Keep the mounting surface clean, flat and free of sundries, deformation and burrs. Align the motor shaft center with the driven load equipment to ensure good coaxiality, and use standard flexible coupling to compensate small installation deviation. Tighten the mounting flange bolts evenly with standard torque to prevent motor shell deformation and internal component stress. Reserve enough space around the motor for natural air circulation heat dissipation and daily maintenance operation. Do not block the motor surface heat dissipation area to avoid poor heat dissipation and abnormal temperature rise. Wiring Requirements All wiring and connection operations must be carried out under complete power cut off condition. Use original FANUC matched power cable, encoder signal cable and grounding wire. Firmly connect the three-phase power line and protective grounding terminal to ensure reliable grounding performance. During wiring layout, separate encoder signal cable from main power cable to avoid electromagnetic interference affecting signal accuracy. All wiring terminals shall be fastened tightly with good insulation performance to prevent short circuit and poor contact. Strictly follow FANUC official standard wiring specifications for wiring connection, do not change the wiring sequence at will. Working Environment The allowable operating ambient temperature is from 0 degrees Celsius to 40 degrees Celsius. Storage ambient temperature ranges from minus 20 degrees Celsius to 60 degrees Celsius. Working relative humidity is 5% to 80%, and condensation phenomenon is not allowed inside and outside the motor. Working altitude shall not exceed 1000 meters above sea level. The surrounding atmosphere shall not contain corrosive gas, flammable explosive dust and excessive oil mist pollution. Avoid long-term exposure to strong mechanical vibration and impact environment. Operation Guidelines The motor must be operated strictly within the rated voltage, torque and speed range, and long-term overload operation is prohibited. After installation and wiring, perform no-load trial operation to check for abnormal noise, vibration and excessive temperature rise. Monitor the motor shell temperature during long-term operation to keep it within the allowable range. Avoid excessive frequent start and stop cycles to prevent motor overheating and mechanical wear and tear. Set the servo amplifier operation parameters reasonably according to the actual motor model and load working condition. Ensure the motor runs within the normal temperature and load range all the time. Maintenance Instructions Regularly cut off the power supply, clean the dust and oil dirt on the motor surface and shell. Periodically check the tightness of mounting bolts, coupling connection and encoder connector plug. Listen to the running sound regularly to judge the working state of internal bearings, and replace bearings in time if abnormal noise occurs. Use CNC system diagnostic function regularly to detect encoder signal quality and positioning stability. It is prohibited to disassemble the motor and encoder privately without authorization, otherwise the precision components will be damaged and the product warranty will be invalid. Keep the motor surface clean and heat dissipation channel unobstructed to ensure long-term stable operation. Safety Precautions Only professionally qualified technical personnel are allowed to carry out installation, wiring and maintenance work of the servo motor. Cut off all input power before maintenance and inspection, and wait for the internal capacitor to complete discharge before operation. It is strictly prohibited to touch the rotating shaft and live electrical parts during motor operation. Must do reliable grounding installation to prevent electric shock accident and reduce electromagnetic interference. Do not arbitrarily modify the internal structure, circuit and encoder configuration of the motor. Keep the motor and matching cables away from flammable materials and high temperature heat source environment.
