When connecting this product to the drive shaft of equipment, shaft misalignment,
shaft deflection, or thrust fluctuation of the drive shaft causes excess force on the
bearing, as a result causing reduced accuracy and serviceability of the encoder,
and damaging to the encoder.
Make sure the work load for each model is within the specified permissible load
when connecting the encoder to equipment.
・When the encoder is rigidly connected to equipment, the shaft misalignment
should be 2 µm or less and the thrust fluctuation should be 1 µm or less. When
precise shaft alignment is impossible, it is recommended to absorb the shaft
misalignment, shaft deflection, or thrust fluctuation by using a flexible coupling.
・A flexible coupling with enough torsional rigidity should be selected to obtain
precise transmission.
・When attaching the flexible coupling to the encoder shaft, be very careful not to
apply any unnecessary load to the encoder shaft. The flexible coupling can be
attached to the static encoder shaft even if the load caused by the deflection and
inclination of the drive shaft exceeds the maximum setting. In this case, however,
trouble may occur because undesired stress can be imposed on the encoder shaft
when it rotates.
