6 Installation6.1.4 Coupling Motor and Machinery6-46.1.4 Coupling Motor and MachineryConsider the following conditions when coupling the motor with the machinery. For the servomotor, only thedirect coupling is available.(1) Direct CouplingCouple the motor with the machinery so that the center of the motor shaft and that of the machinery shaft areon 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 properlyaligned.• Do not allow any direct impact to the shafts when installing the couplings. Do not hitthe area near encoders with a hammer etc., as impacts may damage the encoders.• Before installation, thoroughly remove the anticorrosive paint from the end of themotor shaft. Only after removing the paint can motors be installed on the machines.Coupling*㧦Alignment AccuracyNote: Turn together with coupling.**LevelTolerance ASurface irregularity B0.03 mm max.0.03 mm max.Spindle MotorStandard0.01 mm max.0.01 mm max.0.03 mm max.0.03 mm max.High-speed type ServomotorABAnticorrosivepaint iscoated here.
