In an FSSB–based system, a fiber optics cable is used to connect the CNC
to servo amplifiers and separate detector interface units. These amplifiers
and separate detector interface units are called slaves. The two–axis
amplifier consists of two slaves, and the three–axis amplifier consists of
three slaves. The slaves are numbered 1, 2, ..., 10 (slave number)
sequentially, with that nearest to the CNC starting at number 1.

The manual setting 1 is valid when the following parameter have the
following values:
Bit 0 of parameter No. 1902 = 1
Bit 1 of parameter No. 1902 = 0
Parameter Nos. 1910 to 1919 = all 0s
By manual setting 1, the value set for parameter No. 1023 when the power
is switched on is regarded as a slave number. Specifically, an axis for
which parameter No. 1023 is set to 1 is connected to the amplifier nearest
to the CNC, while an axis for which parameter No. 1023 is set to 2 is the
second one from the CNC.
