Specifications and Ratings
4.2.1
Specifications
*1.
A vibration class of V15 indicates a vibration amplitude of 15
μ
m maximum on the Servomotor without a load at
the rated motor speed.
*2.
The hollow hole section, motor mounting surface, output shaft surface, and gap around the rotating part of the
shaft are excluded. Protective structure specifications apply only when the special cable is used. The protective
structure is IP40 for CE Marking.
*3.
Refer to the following figure for the relevant locations on the Servomotor. Refer to the dimensional drawings of
the individual Servomotors for more information on tolerances.
*4.
The given values are for when the Servomotor shaft is mounted horizontally and shock or vibration is applied in
the directions shown in the following figures.
The strength of the vibration that the Servomotor can withstand depends on the application. Check the vibration
acceleration rate.
