6 - 2
6-1  Installing the servomotor 
 
 
CAUTION
 
1.  Do not hold the cables, shaft or detector when transporting the motor.  Failure 
to observe this could result in breakage and injury. 
2.  Securely fix the motor onto the machine. Improper fixing could cause the 
motor to dislocate and result in injury. 
3.  Do not apply impact, such as by tapping with a hammer, when connecting the 
coupling to the servomotor's shaft end. The detector could break. 
4.  Never touch the motor's rotating sections during operation. Provide a cover, 
etc., on the shaft. 
5.  Do not apply a load exceeding the tolerable load on the servomotor shaft. 
Failure to observe this could result in shaft breakage and injury. 
6.  Do not connect or disconnect any connector while the power is ON.
