2.2.2 Servomotor Ratings
*1. These values are for operation in combination with a SERVOPACK when the temperature of the armature wind-
ing is 100°C. The values for other items are at 20°C. These are typical values.
*2. The rated torques are the continuous allowable torque values at 40°C with an aluminum heat sink of the dimen-
sions given in the table.
*3. This does not apply to the connectors or shaft opening. Protective structure specifications apply only when the
special cable is used.
*4. The allowable shaft loads are illustrated in the following figure. Design the mechanical system so that the thrust
and radial loads applied to the Servomotor shaft end during operation do not exceed the values given in the
table.
2.2.3 Torque-Motor Speed Characteristics
Note: 1. These values are for operation in combination with a SERVOPACK when the temperature of the armature
winding is 100°C. These are typical values.
2. The characteristics in the intermittent duty zone depend on the power supply voltage.
3. If the effective torque is within the allowable range for the rated torque, the Servomotor can be used within
the intermittent duty zone.
4. The Servomotor Power Supply Cable may cause a voltage drop, which may reduce the intermittent duty
zone of the torque-motor speed characteristics.
