3.5.5 Impact Resistance
Note Radial and thrust load limit value are the sum of the loads generated by the motor
torque and external loads applied to the shaft.
3.5.3 Mechanical Tolerances
Tolerances for AC Servomotor output shaft and installation are shown in
Table 3.2.

Note T.I.R. = Total Indicator Reading
3.5.4 Direction of Motor Rotation
AC Servomotor rotation when a positive direction instruction (and direction instruction) is input
is counterclockwise as viewed from the load end of the shaft.

3.5.5 Impact Resistance
Mount the servomotor with the axis horizontal. The servomotor must withstand the following
vertical impacts.
• Impact Acceleration: 490 m/s2 (50 G)
• Number of Impacts: 2
(SGMP-15A)
• Impact Acceleration: 98 m/s2 (10 G)
