Variables associated with the main spindle
PRGCSS
It returns the constant surface speed selected by program. Its value is given in m/min or ft/min.
Variables associated with the spindle override
The variable PLCSSO is a read-write variable, the rest are read-only.
SSO
It returns the turning speed override (%) of the main spindle currently selected at the CNC. It is given
in integer values between 0 and "MAXFOVR" (maximum 255).
This turning speed percentage of the main spindle may be indicated by program, by PLC, by DNC
or by the front panel; the CNC selects one of them and the priority (from the highest to the lowest)
is: by program, by DNC, by PLC and from the panel frontal.
PRGSSO
This variable may be used to read or modify the speed override percentage of the main spindle
currently selected by program. It is given in integer values between 0 and "MAXFOVR" (maximum
255). If it has a value of 0 it means that it is not selected.
DNCSSO
It returns the turning speed override % of the main spindle currently selected via DNC. If it has a
value of 0 it means that it is not selected.
PLCSSO
It returns the turning speed override % of the main spindle currently selected by PLC. If it has a value
of 0 it means that it is not selected.
CNCSSO
It returns the turning speed override % of the main spindle currently selected from the front panel.
Speed limit related variables
PLCSL and MDISL are read-write variables, the rest are read-only.
SLIMIT
It returns the value set in rpm at the CNC for the turning speed limit of the main spindle.
This limit 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.
DNCSL
It returns the speed limit of the main spindle in rpm currently selected via DNC. If it has a value of
0 it means that it is not selected.
PLCSL
It returns the speed limit of the main spindle in rpm currently selected by PLC. If it has a value of
0 it means that it is not selected.
PRGSL
It returns the speed limit of the main spindle in rpm currently selected by program.
MDISL
Maximum machining spindle speed. This variable is also updated (refreshed) when programming
function G92 via MDI.
