2.3 Load mounting/dismounting precautions
POINT
During assembling, the rotor must not be hammered. Otherwise, the encoder
may malfunction.
(1) The direction of the encoder on the direct drive motor cannot be changed.
(2) When mounting the direct drive motor, use spring washers, etc. and fully tighten the bolts so that they do
not become loose due to vibration.
2.4 Permissible load for the rotor
CAUTION
Because the rigid coupling may damage the rotor, make sure to align and center
the load on the rotor.
For the permissible rotor load specific to the direct drive motor, refer to section 7.3.
(1) When coupling a load to the direct drive motor, the load applied to the rotor must be within the
permissible load.
(2) The load, which exceeds the permissible load, can cause the bearing life to reduce and the rotor to
break.
(3) The load indicated in this section is static load in a single direction and does not include eccentric load.
Make eccentric load as small as possible. Not doing so can cause the direct drive motor to be damaged.
