on a straight line. Insert a liner for adjustment, if necessary.
• Install the servomotor so that alignment accuracy falls within the following range.
Vibration that will damage the bearings and encoders if the shafts are not properly
aligned.
• Do not allow any direct impact to the shafts when installing the couplings. Do not hit
the area near encoders with a hammer etc., as impacts may damage the encoders.
• Before installation, thoroughly remove the anticorrosive paint from the end of the
motor shaft. Only after removing the paint can motors be installed on the machines.
