*1. The gear output torque is expressed by the following formula.
Gear output torque = Servomotor output torque ×
The gear efficiency depends on operating conditions such as the output torque, motor speed, and temperature.
The values in the table are typical values for the rated torque, rated motor speed, and a surrounding air tem-
perature of 25°C. They are reference values only.
*2. When using an SGM7A-A5A, SGM7A-01A, or SGM7A-C2A Servomotor with a gear ratio of 1/5 or an SGM7A-
C2A Servomotor with a gear ratio of 1/11, maintain an 85% maximum effective load ratio. For an SGM7A-C2A
Servomotor with a gear ratio of 1/21 or 1/33, maintain a 90% maximum effective load ratio. The values in the
table take the effective load ratio into consideration.
*3. The instantaneous maximum torque is 300% of the rated torque.
