B-63530EN/03 4.DESCRIPTION OF PARAMETERS
- 271 -
PCS When two or three paths are used and multi-spindle control is
exercised on each path, the selection of the feedback signal of the
position coder in a selected path, regardless of the state of the
PC2SLC signal (G0028#7, G1028#7, G2028#7) of the selected path,
is:
0 : Impossible.
1 : Possible. (When three paths are used, the position coder of a path
is selected with signals below:
SLPCA
#1
<G0064#2>, SLPCA
#2
<G1064#2>,
SLPCA
#3
<G2064#2>, SLPCB
#1
<G0064#3>,
SLPCB
#2
<G1064#3>, SLPCB
#3
<G2064#3>)
On a 3-path lathe, a position coder feedback signal selection can be
made as indicated in the table below. (The "-" mark indicates
irrelevancy to PC selection on the path side.)
<1> When the bit 3 (PCS) of Parameter No.3706 is set to 1.
