4-3-1 Environmental conditions 
4-3-2 Shaft characteristics
There is a limit to the load that can be applied on the motor shaft. Make sure that the load applied on the 
radial direction and thrust direction, when mounted on the machine, is below the tolerable values given 
below. These loads may affect the motor output torque, so consider them when designing the machine.
(Note 1) The tolerable radial load and thrust load in the above table are values applied when each motor is 
used independently.
(Note 2) The symbol L in the table refers to the value of L below.
L: Length from flange installation surface to center of load mass [mm]
