7.2.2 Servomotor Ratings of the SGM7G-03 to -20
7-4
*4.
Refer to the following section for information on derating rates for surrounding air temperatures.
7.2.9 Servomotor Derating Rates for Surrounding Air Temperatures
*5.
If the altitude will exceed 1,000 m, refer to the following section.
7.2.10 Applications Where the Altitude of the Servomotor Exceeds 1,000 m
*6.
If you use the Servomotor together with a
Σ
-7W or
Σ
-7C SERVOPACK, the control gain may not increase as
much as with a
Σ
-7S SERVOPACK and other performances may be lower than those achieved with a
Σ
-7S
SERVOPACK.
