9. SPINDLE SPEED FUNCTION
739
If the first spindle is a serial spindle, the second and third spindles can also
be used in a two--path lathe application. (See Section 9.2.)
In the following chart, all spindles are connected under two--spindle
control.
Under one--spindle control, any spindle (SP1

post 2 cannot be used.

Fig. 9.4 (e) Spindle configuration and flow of commands and feedback signals in an two --path lathe application
(with all spindles under two--spindle control)
The second and third spindles should be controlled using the PMC or be
under multi--spindle control. (See Section 15.4 or 9.10.)
If multi--spindle control is applied to both tool posts, the position coder
feedback signal for the second spindle of each tool post also becomes
usable.
See descriptions of bit 3 (PCS) of parameter No. 3706.
