Installation
4.1.4
Connecting Servomotor to Machine
The end of the motor shaft is coated with anticorrosive paint. Thoroughly remove the paint prior to installa-
tion.
Align the shaft of the servomotor with the shaft of the machine, and then couple the shafts. Install the servo-
motor so that alignment accuracy falls within the following range. Vibration will damage the bearings or
encoders if the shafts are not properly aligned.
Do not allow direct impact to be applied to the shafts when installing the coupling as the encoder mounted on
the opposite end of the shaft may be damaged.

Except through shaft section.
Measure this distance at four
different positions on the
circumference. The difference
between the maximum and
minimum measurements must be
0.03 mm or less.
(Turn together with coupling.)
