1.2 Installation of Spindle Motor
1.2.1 Environmental Conditions
(Note) Refer to each spindle motor specifications for details on the spindle motor vibration class.
CAUTION
1. Do not hold the cables, axis or encoder when transporting the motor. Failure to observe this could lead to faults or
injuries.
2. Securely fix the motor to the machine. Insufficient fixing could lead to the motor deviating during operation. Failure to
observe this could lead to injuries.
3. When coupling to a servo motor shaft end, do not apply an impact by hammering, etc. The encoder could be damaged.
4. Never touch the rotary sections of the motor during operations. Install a cover, etc., on the shaft.
5. Do not apply a load exceeding the tolerable load onto the servo motor shaft. The shaft could break. Failure to observe
this could lead to injuries.
6. Do not connect or disconnect any of the connectors while the power is ON.
7. When coupling the motor directly with the spindle, perform the adequate centering and parallel correcting with the axis to
be coupled. The vibration of the motor should be 4.9m/s
2
(0.5G) or less after balancing the spindle unit.
8. Perform a running-in before operating the machine.
