*4.
The given values are for when the Servomotor shaft is mounted horizontally and shock or vibration is applied in
the directions shown in the following figures.
The strength of the vibration that the Servomotor can withstand depends on the application. Check the vibration
acceleration rate.

These values are for operation in combination with a SERVOPACK when the temperature of the armature wind-
ing is 20°C. These are typical values.
*2.
The rated torques are the continuous allowable torque values at a surrounding air temperature of 40°C with a
steel heat sink of the dimensions given in the table.
*3.
The thrust loads and moment loads that are applied while a Servomotor is operating are roughly classified into
the following patterns. Design the machine so that the thrust loads or moment loads will not exceed the values
given in the table.
Where F is the external force,
Thrust load = F + Load mass
Moment load = 0
Note: For the bearings used in these Servomotors, the loss depends on the bearing temperature. The amount of
heat loss is higher at low temperatures.
