10.4 Multiple spindle control I

10.4.1 Multiple spindle control

Function and purpose
Spindle rotation command for up to 7 spindles is provided.
Although the S ∗∗∗∗∗ command is normally used to designate the spindle rotation speed, the
Sn= ∗∗∗∗∗ command is also used for multiple spindle control.
S commands can be issued from the machining program of any part systems.
Number of usable spindles differ the machine model, confirm the specifications of the model used.
Command format
Sn=∗∗∗∗∗ ;
n
∗∗∗∗∗
Detailed description
(1) Each spindle command is delimited by the details of n.
(Example)
S1 = 3500 ; 1st spindle 3500(r/min) command
S2 = 1500 : 2nd spindle 1500(r/min) command
S3 = 2000 ; 3rd spindle 2000(r/min) command
S4 = 2500 : 4th spindle 2500(r/min) command
S5 = 2000 ; 5th spindle 2000(r/min) command
S6 = 3000 : 6th spindle 3000(r/min) command
S7 = 3500 ; 7th spindle 3500(r/min) command
(2) Multiple spindles can be commanded in one block.
(3) If two or more commands are issued to the same spindle in a block, the command issued last
will be valid.
(Example) S1 = 3500 S1 = 3600 S1 = 3700 ;
(4) The S ∗∗∗∗∗ command and Sn= ∗∗∗∗∗ command can be used together.
The spindle targeted for the S ∗∗∗∗∗ command is normally the 1st spindle, however, the S ∗∗∗∗∗
command can be used for 2nd or following spindle according to the spindle selection command.
(5) The commands for each spindle can be commanded from the machining program of any part
systems.
The spindles will rotate with the speed commanded last.
If the S commands are issued from two or more part systems, the command from the part
system of largest No. will be valid.
(6) As for C6 T-type and L-type, C64 T-type, and C64T T-type, the multiple spindles control can
not be used in a part system. A program error (P33) will occur when the Sn= ∗∗∗∗∗ command is
issued. Refer to "10.4.2 Spindle selection command" for details.
S6-digit binary data.
Designate the spindle number with one numeric character.

10.4 Multiple spindle control I
S1 = 3700 will be valid.
