-Multi-spindle control and commands from other paths
If a single path contains other spindles (such as servo motor as a live tool),
executing rotation commands requires the multi-spindle control function.
You can execute commands from other paths with the path spindle control
function. You can select the spindle of another path with spindle selection
with multi-spindle address P.
The following shows program command examples.
Example 1) (spindle selection with an address P)
MPP, bit 3 of parameter No. 3703 = 1: Allows spindle selection with
an address P.
Spindle configuration (S1: first spindle, S2: second spindle)
Path 1 Path 2
S1 (Spindle motor) S3 (Spindle motor)
S2 (Servo motor) S4 (Servo motor)
In a multi-spindle environment, address P settings to select a spindle (parameter No. 3781)
Path 1 Path 2

12(S2) 22(S4)

-Operation on a rotation axis with a servo motor (automatic/manual)
After performing a reference position return, you can perform the same
operation as that in the normal servo axis state and in spindle speed control
mode. You must perform manual operation can perform manual operation
on the servo motor rotation axis while SV speed control mode is OFF.
