Constant surface speed control is modified.
S command without address P
When parameter MPP is set to 1, CNC generates
the alarm 5305 if P code is not commanded at the same block
which commanded S code.
Example
S100 P1 ; OK
P1 ; Address P is used for the other function.
S100 ; Alarm 5305 occurs.
Plural address P
This function cannot command two or more spindle by one
block.
Example
S100 P1 P2 ; Not available
S100 P1 S200 P2 ; Not available
The other function
which uses address P
This function must not be used in the same block with any
command which uses address P.
If the following G codes are commaned with S_P_ at the same
block, alarm 5305 is occurs.
G codes which cannot be commanded with S_P_ :
G04,G26,G30,G31,G71-G76,G83-G89,G251
Prural S command from
multi-paths
In a multi path system, when speed is commanded from two or
more paths to the same spindle, the spindle is controlled by the
S code speed which commanded at the latest.
Example
(1) When S100 P11 is executed on path-1, the 1st spindle on
path-1 rotates at 100 rpm.
(2) When S200 P11 is executed on path-2, the 1st spindle on
path-1 accelerates to 200 rpm. (Refer to figure C-5.)
