These items and torque-motor speed characteristics quoted in combination with a DR2
Servopack at an armature winding temperature of 100
°
C. Other values quoted at 20
°
C. All
values typical at power voltage 200V.

Rated torques are continuous allowable torque values at 40
°
C with a 250 x 250 x 6 (mm)
(9.84 x 9.84 x 0.24 (in.)) heat sink attached.
NOTE
The ratings and specifications above refer to a standard Servomotor.
Add the numerical values below to the moment of inertia values in the table for a motor
fitted with
a holding brake
and/or a 12-bit absolute encoder.
Other specifications will also change slightly.
TERMS
Holding Brake
The holding brake is automatically applied to the
motor shaft to prevent the load falling in vertical axis
applications when the motor power supply is turned
off or fails. It is only to hold the load and cannot be
used for stopping motor.
