1. Installation
1 - 8
1-2 Installation of spindle motor
CAUTION
1. Do not hold the cables, axis or detector 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 servomotor shaft end, do not apply an impact by
hammering, etc. The detector 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 servomotor 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.

Refer to each spindle motor specifications for details on the spindle motor vibration conditions.
1-2-2 Tolerable load of axis
There is a limit to the load that can be applied on the motor shaft. Make sure that the load applied on the
radial direction, when mounted on the machine, is below the tolerable values given below. These loads
also affect the motor output torque, so consider them when designing the machine.
