13.9.3 Relation with Other Functions

 Spindle clamp speed setting (G92)
This is valid only on the spindle selected with the spindle selection signal (SWS).
The spindle not selected with the spindle selection signal (SWS) maintains the speed at which it was rotating before being
canceled.
(The spindle clamp speed is maintained with the G92 command.)
 Constant surface speed control
Constant surface speed control can be applied on all spindles.
The spindle rotation speed is automatically controlled during constant surface speed control, so when machining with con-
stant surface speed, the spindle selection signal (SWS) for that spindle must be left ON.
The spindle not selected with the spindle selection signal (SWS) maintains the speed at which it was rotating before being
canceled.
 Thread cutting/synchronous feed
The threads are cut with the spindle selected with the spindle selection signal (SWS). The encoder feedback selected with
the encoder selection signal is used.
 Synchronous tapping
The synchronous tapping spindle is selected with the spindle selection signal (SWS).
Select the synchronous tapping spindle before issuing the synchronous tapping command. Do not change the synchronous
tapping spindle selection signal during the synchronous tapping mode.
If a C axis mode command is issued to the synchronous tapping spindle, the "M01 operation error 1026" will occur. When
the C axis command is canceled, the error will be canceled and machining will resume.
 Asynchronous tapping
The asynchronous tapping spindle is selected with the spindle selection signal (SWS).
Select the asynchronous tapping spindle before issuing the tapping command. Input a calculation request to change the
asynchronous tapping spindle selection. Do not change the asynchronous tapping spindle selection signal during the asyn-
chronous tapping mode.
 Tapping retract
The tapping retract spindle is selected with the spindle selection signal (SWS).
Select the spindle for which the tapping cycle execution is stopped before turning the tapping retract signal ON. If tapping
retract is executed when a different spindle is selected, the "M01 operation error 1032" will occur. Do not change the spin-
dle selection signal during tapping retract.
 Synchronous tapping with analog I/F spindle
When you command the synchronous tapping with analog I/F spindle with this function enabled, select the spindle to com-
mand the synchronous tapping with analog I/F spindle with the "Spindle selection" signal (SWS) before the block where the
tapping cycle is commanded, then turn the "Recalculation request" signal (CRQ: YC2B) ON.

13.9.4 Restrictions

 The S manual numerical value command is invalid when multiple-spindle control II is valid.
 Setup parameter "#1199 Sselect" is invalid when multiple-spindle control II is valid.
 The spindle control mode changeover G code cannot be used when multiple-spindle control II is valid. A program error
(P34) will occur.
 The "S1=***" and "S2=***" commands are invalid when multiple-spindle control II is valid. The program error (P33) will
occur.
 The spindle gear shift command output signal (GR1/GR2) is not output when multiple-spindle control II is valid.
