*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.
Refer to the following section if the surrounding air temperature exceeds 40
°
C.
5.2.11 Applications Where the Surrounding Air Temperature of the Servomotor Exceeds 40
*5.
If the altitude will exceed 1,000 m, refer to the following section.
5.2.12 Applications Where the Altitude of the Servomotor Exceeds 1,000 m
*6.
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.
