Refer to the following section for information on derating rates for surrounding air temperatures.
*4.
*5. If the altitude will exceed 1,000 m, refer to the following section.
If you use the Servomotor together with a Σ-7W or Σ-7C SERVOPACK, the control gain may not increase as
*6.
much as with a Σ-7S SERVOPACK and other performances may be lower than those achieved with a Σ-7S
SERVOPACK.
