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.
