Motor Total Indicator Readings
The following figure shows tolerances for the servomotor’s output shaft and installation area. For more details
on tolerances, refer to the external dimensions of the individual servomotor.
3.2.8
Rotation Direction
Forward rotation of the servomotor is counterclockwise when viewed from the
load. The rotation direction can be reversed with parameter Pn000.0. For details,
refer to
8.4.1 Servomotor Rotation Direction
.
3.2.9
Shock Resistance
When the servomotor is mounted with the axis horizontal, the servomotor will
withstand the following vertical impacts:
• Impact Acceleration: 490 m/s
2
• Impact occurrences: 2
3.2.10
Vibration Resistance
The servomotor will withstand the following vibration acceleration in three
directions: Vertical, side to side, and front to back.
3.2.11
Vibration Class
The vibration class for the servomotors at rated motor speed is V15.
(A vibration class of V15 indicates a total vibration amplitude of 15
µ
m maximum on the servomotor during
rated rotation.)
