*2.
The rated torque s are the continuou s allowable torque value s at a s urrounding air temperature of 40

C with a s teel heat

*3.
To externally connect dynamic brake re s i s tor, s elect hardware option s pecification 020 for the SERVOPACK. However, you
cannot externally connect dynamic brake re s i s tor if you u s e the following SERVOPACK s (maximum applicable motor capacity:
400 W).

The thru s t load s and moment load s that are applied while a Servomotor i s operating are roughly cla ss ified into the follow-
ing pattern s . De s ign the machine s o that the thru s t load s or moment load s will not exceed the value s given in the table.

If you u s e an SGD7S-7R6A SERVOPACK and SGM7F-35D Servomotor together, u s e thi s value (a derated value).
Note: For the bearing s u s ed in the s e Servomotor s , the lo ss depend s on the bearing temperature. The amount of heat lo ss i s
higher at low temperature s .
