3.2.4 Rotating Direction
AC Servomotor rotates CCWviewed from the load side when connection shown _n Par. 3.3.1
is performed and forward command is given to Servopack with parameter 14, bO setting
: 0 (Fig. 3. 11).
3.2.5 Shock Resistance
Whenmounted horizontally and exposed to vertical shock impulses, the motor can withstand
up to two incidents with shock acceleration of 490 m/s2(5OG) (Fig. 3.12).
Note
A precision detector is mounted on the opposite drive end of AC servomotor. Care
should be taken to protect the shaft from impacts that could damagethe detector.
3.2.6 Vibration Resistance
Whenmounted horizontally, the motor can withstand vibration (vertical, lateral, axial)
of 24.5m/sZ(2.5G) (Fig. 3.13).
3.2.7 Vibration Class
Vibration of the motor running at rated speed is 15_m or below (Fig. 3. 14).
