*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.
If you use an SGD7S-120A008 SERVOPACK and SGM7D Servomotor together, use the ratios given on the bot-
tom line.
*3.
The thrust loads and moment loads that are applied while a Servomotor is operating are roughly classified into
the following patterns. Design the machine so that the thrust loads or moment loads will not exceed the values
given in the table.
The allowable load is for a static load in one direction.
When designing the system, multiply the allowable load by the following safety coefficient depending on the
type of load.
• Smooth load with no shock: 1/3
• Light repetitive load: 1/5
• Shock load: 1/10
