14.15 Related to the spindle speed
These variables are synchronous read/write (R/W).
They have generic names.
• Replace the "n" character with the channel number, maintaining the brackets. The first
channel is identified with the number 1, "0" is not a valid number.
• Replace the "Sn" character by the name, logic number or index in the channel of the spindle.
These variables only limit the spindle turning speed (rpm) when constant surface speed is active. The
maximum Constant Surface Speed may be set by program or by PLC; the one set by PLC has the
highest priority.
V.A.SREAL.Sn V.A.SREAL.S
TURNING SPEED
PRG PLC INT Exec
(V.)[n].A.SREAL.Sn
Real spindle speed R R R Yes
It takes the spindle speed override into account.
When the spindle is stopped, it returns a value of 0. When working in G96 and G97, the speed is in rpm
and when working with M19, in º/min.
SPINDLE SPEED IN G97
PRG PLC INT Exec
(V.)[n].A.SPEED.Sn
S active in rpm (G97) R R R Yes
(V.)[n].PLC.S.Sn
S by PLC in rpm R R/W R Yes
(V.)[n].A.PRGS.Sn
S by program in rpm R R R No
The speed may be set by program or by PLC; the one set by PLC has the highest priority.
SPINDLE SPEED IN CSS PRG PLC INT Exec
(V.)[n].A.CSS.Sn
Active CSS R R R Yes
(V.)[n].PLC.CSS.Sn
CSS by PLC R R/W R Yes
(V.)[n].A.PRGCSS.Sn
CSS by program R R R No
The speed may be set by program or by PLC; the one set by PLC has the highest priority.
MAXIMUM CONSTANT SURFACE SPEED
PRG PLC INT Exec
(V.)[n].A.SLIMIT.Sn
S limit active in Constant Surface Speed mode R R R Yes
(V.)[n].PLC.SL.Sn
S limit via PLC in Constant Surface Speed mode R R/W R Yes
(V.)[n].A.PRGSL.Sn
S limit via program in Constant Surface Speed mode R R R No
SPINDLE SPEED OVERRIDE
PRG PLC INT Exec
(V.)[n].A.SSO.Sn
% S active at the CNC R R R Yes
(V.)[n].A.PRGSSO.Sn
% S by program R/W R R No
(V.)[n].PLC.SSO.Sn
% S by PLC R R/W R Yes
(V.)[n].A.CNCSSO.Sn
% S at the switch R R R/W Yes
The spindle speed override may be set by program, by PLC or with the selector switch; the one set by
program has the highest priority and the one set with the selector switch has the lowest.
SPEED IN M19
PRG PLC INT Exec
(V.)[n].A.SPOS.Sn
Active speed in M19 R R R Yes
(V.)[n].PLC.SPOS.Sn
Speed in M19 set by PLC R R/W R Yes
(V.)[n].A.PRGSPOS.Sn
Speed in M19 by program R R R No
