* 1 These items and torque-motor speed characteristics quoted in combination with an SGDB
SERVOPACK at an armature winding temperature of 100°C. Other values quoted at
20°C. All values typical.
* 2 Rated torques are continuous allowable torque values at 40°C with a 300¢300¢12 (mm)
(11.81¢11.81¢0.47 (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.
Other specifications will also change slightly.
