IO1 A first FSSB I/O unit is:
0: Not used.
1: Used.
IO2 A second FSSB I/O unit is:
0: Not used.
1: Used.
CAUTION
1 The FSSB I/O unit and separate detector interface
unit (pulse module) are handled as units of the same
type on the FSSB. The term "first unit" or "second
unit" used in the following description means that the
unit is the first or second one when counted
disregarding the difference between the FSSB I/O
unit and separate detector interface unit. If one
FSSB I/O unit and one separate detector interface
unit are connected and if the separate detector
interface unit is closer to the CNC on the FSSB than
the FSSB I/O unit, for instance, the FSSB I/O unit is
referred to as the "second unit."
2 The FSSB I/O basic unit is controlled on the first
servo axis. Set IO1 (or IO2) to 1 for an axis for which
parameter No.1023 is set to 1 (to 9 for tool post 2
under 2-CPU 2-path control or 2-CPU 3-path
control). Set 0 in the parameter No. 1936 (or No.
1937) for the corresponding axis.
3 The FSSB I/O extension unit is controlled with 2nd
servo axis. With an axis for which parameter No.
1023 is set to 2 (for which parameter No. 1023 is set
to 10 when tool post 2 is used in 2-CPU 2-path
control or tool post 2 is used in 2-CPU 3-path
control), set IO1 (or IO2) = 1. Set 1 in parameter No.
1936 (or No. 1937) for the corresponding axis.
4 When using the 1st (9th) servo axis and FSSB I/O
extension unit, set IO1 = 0 and IO2 = 0 for those
axes other than the 2nd (10th) servo axis.
5 When using an FSSB I/O extension unit in a
configuration where the 2nd servo axis (axis for
which parameter No. 1023 is set to 2 or 10) is
missing, add an axis for which parameter No. 1023
is set to 2 or 10 as a dummy axis and set the serial
feedback dummy function (by setting bit 0 of
parameter No. 2009 to 1).
