The slave is the generic name of a servo amplifier or separate detector
interface unit connected to the CNC via an FSSB optical cable. The
numbers from 1 to 10 are assigned to the slaves in ascending order; a
younger number is assigned to a slave that is closer to the CNC. A 2–axis
amplifier consists of two slaves, and a 3–axis amplifier consists of three
slaves. Set each of the parameters as described below according to which
of the three cases is applicable: the slave is an amplifier, the slave is a
separate detector interface unit, or there is no slave.
` When the slave is an amplifier:
Set a value obtained by subtracting 1 from the setting of parameter No.
1023 for the axis to which the amplifier is assigned.
` When the slave is a separate detector interface unit:
S For the first separate detector interface unit (closest to the CNC),
set 16.
S For the second separate detector interface unit (farthest from the
CNC), set 48.
` When there is no slave:
Set 40.
These parameters are automatically set by data input on the FSSB setting
screen when the FSSB setting mode is the automatic setting mode (when
bit 0 of parameter No. 1902 = 0). When the manual setting 2 mode is used
(when bit 0 of parameter No. 1902 = 1), be sure to enter necessary data
directly.
