2.1.3 Installation Precautions
Table 2-2 Installation precautions
Item Description
Rust-proof
treatment
Wipe up the antirust agent at the motor shaft end before installing the servo motor,
and then take rust-proof treatment.
Encoder
•
Do not strike the shaft end during installation. Failure to comply will lead to
damage to the internal encoder.
•
Use the screw hole at the shaft end when mounting a pulley to the servo motor
shaft with a keyway. To îš¿t the pulley, insert a double-end screw into the screw hole
of the shaft, put a washer against the coupling end, and then use a nut to push
the pulley in.
•
For the servo motor shaft without a keyway, use friction coupling or the like.
•
When removing the pulley, use a pulley remover to protect the shaft from suffering
severe impact from load.
•
To ensure safety, install a protective cover or similar device on the rotary area
such as the pulley mounted on the shaft.

Alignment
Align the shaft of the servo motor with the shaft of the equipment and then couple
the shafts. When installing the servo motor, make sure that the alignment accuracy
satisîš¿es the requirement as described in the following îš¿gure. If the shafts 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
The servo motor can be installed horizontally or vertically.
