Serial communications using optical fiber cable is used as the servo
interface.
For details on connections relating to the control motor amplifier ALPHA
series, refer to the FANUC SERVO AMPLIFIER ALPHA Series
Specifications (B–65162E).

All servo amplifiers
in this example are

– When servo HRV3 is used, an axis control card supporting servo
HRV is required. In addition, when servo HRV3 is used, the servo
amplifiers used must be amplifiers for high–speed HRV current con-
trol or servo HRV3 amplifiers.
– Up to eight axes in total can be connected to the FSSB line.
– The total number of axes and separate detectors connected to one
servo card must be 10 or less. (Nine in total in this example)
– Cards used for two to eight axes are all classified as TYPE A.
