*1. The rated torques are the continuous allowable torque values at a surrounding air temperature of 40°C with an
aluminum heat sink of the dimensions given in the table.
*2. The repetitive rated torque is the value for 60% ED.
*3. To externally connect dynamic brake resistance, select hardware option specification 020 for the SERVOPACK.
However, you cannot externally connect dynamic brake resistance if you use the following SERVOPACKs (max-
imum applicable motor capacity: 400 W).

• SGD7S-2R800A020F83
*4. If you use an SGD7S-120A008 SERVOPACK and SGM7D Servomotor together, use the ratios given on the bot-
tom line.
