Connecting Servomotor To Machine; Protective Structure - YASKAWA E-V-MD Series User Manual

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.
