In an FSSB--based system, a fiber optics cable is used to connect the CNC
to servo amplifiers and pulse modules. These amplifiers and pulse
modules 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 usable when the following parameter
specifications made:
Bit 0 of parameter No. 1902 = 0
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
connected to the amplifier nearest but one to the CNC.
