13.9 Multiple-Spindle Control II
Operation when the spindle function (S) command and miscellaneous function (M) command are issued
in the same block
When a spindle function (S) command is given in the same block as an M code for spindle selection (SWS: Y18A8) or for
spindle command selection (SLSP: R7002), you can select the spindle to update the spindle command rotation speed input
(R6500/R6501) with the parameter "#1300 ext36/bit3 (Spindle command rotation speed input timing selection)".
 Spindle command rotation speed input timing selection: Invalid (parameter #1300 ext36/bit3 = 0)
The spindle command rotation speed input (R6500/R6501) is updated for the spindle (the currently selected spindle) before
selected in the same block.
 Spindle command rotation speed input timing selection: Valid (parameter #1300 ext36/bit3 = 1)
The spindle command rotation speed input (R6500/R6501) is updated for the spindle after selected in the same block.
Shown below is a timing chart of the 1st spindle command rotation speed when the spindle is used in two different part
systems.
M3 command selects the 1st spindle and runs it forward.

(1) M3 command, given in the same block as the spindle function (S) command, selects the spindle.
When the spindle command rotation speed input timing selection is invalid, the part system selected for the 1st spindle is
switched to the 1st part system, but the 1st spindle remains at a standstill. (*1)
When the spindle command rotation speed input timing selection is valid, the part system selected for the 1st spindle is
switched to the 1st part system, and the 1st spindle rotates at the commanded speed of 100r/min at the same time.
(2) When the spindle function (S) command is given in the 1st part system, the rotation speed of the selected spindle (1st
spindle) becomes 100r/min.
(3) M3 command, given in the same block as the spindle function (S) command selects the spindle.
When the spindle command rotation speed input timing selection is invalid, the part system selected for the 1st spindle is
switched to the 2nd part system, but the 1st spindle remains at the present speed (100r/min). (*1)
When the spindle command rotation speed input timing selection is valid, the part system selected for the 2nd spindle is
switched to the 2nd part system, and the 1st spindle rotates at 50r/min at the same time.
(4) When the spindle function (S) command is given in the 2nd part system, the rotation speed of the selected spindle (1st
spindle) becomes 80r/min.
(*1) The spindle function (S) command updates the spindle command rotation speed input for the spindle selected before the
block.
