271
J Vibration Resistance
Mount the servomotor with the axis horizontal.
The servomotor must withstand the following
vibration accelerations in three directions: verti-
cal, transverse, and longitudinal.
• Vibration Acceleration: 24.5 m/s 2
J Vibration Class
The SGMj servomotor meets the following
vibration class at rated speed.
• Vibration Class: 15µm or below
TERMS
Vibration Class
Vibration class 15µm or below indicates that the total amplitude of vibration of the motor
alone, running at rated speed, does not exceed 15µm.
