Direction Of Servomotor Rotation; Impact Resistance; Vibration Resistance; Vibration Class - YASKAWA SGM H Series User Manual

3.8.3 Direction of Servomotor Rotation

Positive rotation of the servomotor is counterclockwise when viewed from the load. (Same as for servomotors
with gears.)
Positive direction

3.8.4 Impact Resistance

Mount the servomotor with the axis horizontal. The servomotor will withstand the following vertical impacts:
• Impact acceleration: 490 m/s
• Impact occurrences: 2
Vertical

3.8.5 Vibration Resistance

Mount the servomotor with the axis horizontal. The servomotor will withstand the following vibration accelera-
tion in three directions: Vertical, side to side, and front to back.
