Specifications and Ratings
3.2.1
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 shock resistance for shock in the vertical direction when the Servomotor is mounted with the shaft in a hor-
izontal position is given in the above table.
*3.
The vertical, side-to-side, and front-to-back vibration resistance for vibration in three directions when the Servo-
motor is mounted with the shaft in a horizontal position is given in the above table. The strength of the vibration
that the Servomotor can withstand depends on the application. Always check the vibration acceleration rate
that is applied to the Servomotor with the actual equipment.
*4.
If you use the Servomotor together with a
Σ
-7W or
Σ
-7C SERVOPACK, the control gain may not increase as
much as with a
Σ
-7S SERVOPACK and other performances may be lower than those achieved with a
Σ
-7S
SERVOPACK.
