Note The values for torque and rotational speed characteristics, are the values at an armature winding tempera-
ture of 100
°
C, combined with the Servo Driver. Other values are at normal conditions (20
°
C, 65%).
The
maximum momentary torque is a reference value.

AC Servomotor Heat Radiation Conditions
When an AC Servomotor is continuously operated at the rated conditions, a heat radiation plate equiva-
lent to an rectangular aluminum plate of t6
×
250 mm is required at the Servomotor flange mounting
area. (This is for horizontal mounting, with nothing around the Servomotor and no interference from
heat convection currents.)
