Variables associated with the main spindle
13.10 Variables associated with the main spindle
Variables associated with the real speed
SREAL
It returns the actual (real) turning speed of the main spindle. Its value is given in 0.0001 rpm units.
FTEOS
It returns the theoretical turning speed of the main spindle.
Variables associated with spindle speed
PLCS is a read-write variable; the rest are read-only.
SPEED
It returns the turning speed of the main spindle currently selected at the CNC. Its value is given in
0.0001 rpm units.
This turning speed may be indicated by program, by PLC or by DNC; the CNC selects one of them,
the one indicated by DNC has the highest priority and the one indicated by program has the lowest
priority.
DNCS
It returns the spindle speed limit selected via DNC. If it has a value of 0 it means that it is not selected.
PLCS
It returns the spindle speed limit selected via PLC. If it has a value of 0 it means that it is not selected.
PRGS
It returns the spindle speed limit selected by programa. If it has a value of 0 it means that it is not
selected.
Variables associated with constant cutting speed (lathe model)
PLCCSS is a read-write variable, the rest are read-only.
CSS
It returns the constant surface speed selected at the CNC.
This constant surface speed may be indicated by program, by PLC or by DNC; the CNC selects one
of them, the one indicated by DNC has the highest priority and the one indicated by program has
the lowest priority.
The values are given in the units set by general parameter INCHES.
If INCHES = 0, in m/min (±999999999).
If INCHES = 1, in ft/min (±393700787).
DNCCSS
It returns the constant surface speed selected via DNC. Its value is given in m/min or ft/min and it
is 0 it means that it is not currently selected.
PLCCSS
It returns the constant surface speed selected by PLC. Its value is given in m/min or ft/min.
