Multi-spindle control (TYPE-B)
Select Type B control by setting parameter MSI No. 3709#2 to "1".
Each spindle has its own SIND, SSIN and SGN signals.
Each of these signals functions regardless of selection state of the
spindle selection signals (SWS1 to SWS4).
When either the spindle selection signals (SWS1 to SWS4) or the
SIND signal for the first, second, third, or fourth spindle is set to "1",
the polarity control signals SSIN, SGN will function.
The concept of Type B multi-spindle control outlined below.

Multi spindle control: when a spindle is selected by address P
If bit 3 (MPP) of parameter No. 3703 is set to 1, a spindle is selected
by address P. This control method is basically the same as TYPE-B.
The first, second, third, and fourth spindles each have their own SIND,
SSIN, and SGN signals. A spindle is selected by the P command
instead of the spindle selection signals (SWS1 to SWS4). The
relationship between the P code and the selected spindle is set in
parameter No. 3781.
Polarity (rotation direction) control signals SSIN and SGN for each
spindle are valid only for the spindle selected by the P command or
for the spindle of which SIND signal is 1.
The concept of multi spindle control (spindle selection by address P)
is outlined below.

P command
In case of multi-path control, the P code becomes valid in all paths.
For example, suppose that the P code to select the first spindle of path
2 is set to 21. When the following is specified in path 1:
S1000 P21;
Then, 1000 is specified for the first spindle in path 2. Therefore, the
same P code cannot be used even in different paths.
