Item Description
Alignment
 
u
 Use the shaft coupling for mechanical connection and align the axis 
of the servo motor with the axis of the equipment. When installing 
the servo motor, make sure that alignment accuracy satises the 
requirements as described in the gure to the left. If the axes are 
not properly aligned, vibration will be generated and may damage 
the bearings and encoder.
Measure the distance at four different 
positions on the circumference. The 
difference between the maximum and 
minimum measurements must be 0.03 mm 
or less.
Installation direction  
u
The servo motor can be installed horizontally or vertically.
Oil and moisture 
countermeasures
1) Do not immerse the servo motor and cables into oil or water during 
use.
2) Conrm the IP class of the servo motor when using it in a place with 
water drops (Except the shaft-through portion)
3) Mount the motor with the cable outlet facing downwards to prevent 
water/oil from owing into the motor (as shown in the following gure).
 
4) In the environment where the shaft-through portion is exposed to oil 
drops, use a servo motor with oil sealing.
5) Observe the following conditions when using the servo motor with oil 
sealing:
Make sure that the oil level is lower than the oil seal lip during use;
Avoid oil accumulation at the oil seal lip when the motor is installed 
vertically upward.
Stress of cables
 
u
 Do not bend or apply tension to the cables, especially the signal 
cables whose core wire is 0.2 or 0.3 mm in diameter. Do not exert 
too much tension on the cables during wiring.
