- 188 -
# 3 PCS When a multi-path system is used, and multi-spindle control is
enabled with each path, as the position coder signals
(PC2SLC<Gn0028.7>, PC3SLC<Gn0026.0>, PC4SLC<Gn0026.1>)
for selecting the position coder of a spindle among the multiple
spindles that belong to a path selected by the inter-path spindle
feedback selection signals:
0: The signals of the path selected by the inter-path spindle feedback
selection signal are used.
1: The signals of the local path are used.
Suppose that path x is selected by the inter-path spindle feedback
selection signals (SLPCA<Gn063.2> to SLPCD<Gn063.5>). Then,
the following position coder is selected in path x by the position coder
selection signals:
n = m(path number)-1
y = x(path number selected by the spindle feedback selection
signals)-1
