Specifications and Ratings
Specifications
*1. A vibration class of V15 indicates a vibration amplitude of 15

m maximum on the Servo
Motor without a load at the rated motor speed.
*2. The shock resistance for shock in the vertical direction when the Servo Motor is mounted with
the shaft in a horizontal 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 Servo Motor can withstand depends on the appli-
cation. Always check the vibration acceleration rate that is applied to
the Servo Motor with the actual equipment.
*4. If the surrounding air temperature will exceed 40°C, refer to the follow-
ing section.
Applications Where the S urroun d ing Air Temperature of the S ervo Motor Excee d s 40°C (page 124)
*5. If the altitude will exceed 1,000 m, refer to the following section.
Applications Where the Altitu d e of the S ervo Motor Excee d s 1,000 m (page 125)
*6. If you use the Servo Motor together with a S-7W SERVOPACK, the control gain may not increase as much as with a S-7S
SERVOPACK and other performances may be lower than those achieved with a S-7S SERVOPACK.
