Specifications and Ratings
Specifications (200 V Models)
*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 application. Always check the vibra-
tion 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 following section.
Applications Where the S urroun d ing Air Temperature
of the S ervo Motor Excee d s 40°C (page 74)
*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 75)
