9. SPINDLE SPEED FUNCTION
598
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 SWS3).
When either the spindle selection signals (SWS1 to SWS3) or the SIND
signal for the first, second, or third spindle is set to “1”, the polarity
control signals SSIN, SGN will function.
The concept of Type B multi-spindle control outlined below.

NOTE
When using an analog spindle, the third spindle is selected.
In this case, the second spindle cannot be used.
In multi-spindle control, the first spindle is the first serial spindle, the
second spindle is the second serial spindle, and the third spindle is an
analog spindle.
The second and third spindles cannot be connected at the same time.
