If you combine a
Σ
-7-Series SERVOPACK with a
Σ
-V-Series Option Module, the surrounding air temperature
specification of the
Σ
-V-Series SERVOPACKs must be used, i.e., 0°C to 55°C. Also, the applicable surrounding
range cannot be increased by derating.
*2.
The coefficient of speed fluctuation for load fluctuation is defined as follows:
*3.
Usable only with SGD7S-210D, -260D, -280D, -370D SERVOPACKs.
*4.
The /DBON signal can be used as positive logic.
*5.
The SGD7S-210D, -260D, -280D, and -370D do not have a dynamic brake (DB). If a dynamic brake is neces-
sary, create an external dynamic brake circuit.
Refer to the following chapter for details on the dynamic brake.
