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.)

Specifications for Servomotors with Magnetic Brakes
The magnetic brakes installed in Servomotors with brakes are status-holding brakes
with non-magnetized operation. The magnetic brake is released when a magnetic cur-
rent (24 VDC) is applied. The magnetic brake is not meant to be used for braking. Using it
for braking will damage it. During Servomotor operation, be sure to release the magnetic
brake by applying a magnetic voltage. The specifications for Servomotors with brakes
are similar to those for Servomotors without brakes, so except for inertia and weight, the
various constants are all the same.
The inertia for magnetic brakes is the load inertia.
Use a separate power supply for the magnetic brake excitation power.
