Shock Applied to the Servomotor
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.

much as with a Σ-7S SERVOPACK and other performances may be lower than those achieved with a Σ-7S
SERVOPACK.
