5.3 Spindle speed (S)
The spindle speed is selected by program using the spindle name
followed by the desired speed. The speeds of all the spindles of the
channel may be programmed in the same block.
The programmed speed stays active until another value is
programmed. The programming units will be RPM unless selected
otherwise.
It is possible to program using parameters or arithmetic expressions.
Spindle start and stop
Defining a speed does not imply starting the spindle. The startup is
defined using the following auxiliary functions. Ver "Spindle control
(M03/M04/M05/M19)" en la página 83.
M03 - Starts the spindle clockwise.
M04 - Starts the spindle counterclockwise.
M05 - Stops the spindle.
Maximum speed
The maximum turning speed in each range (gear) is limited by the
machine manufacturer. When programming a higher turning speed,
the CNC limits its value to the maximum allowed by the active range
(gear). The same thing occurs when trying to exceed the maximum
limits using the "+" and "-" keys of the operator panel or doing it via
PLC or by program.
Speed override
The programmed "S" speed may be varied between 50% and 120%
using the "+" and "-" of the operator panel or via PLC. However the
maximum and minimum variation may be different depending on how
the machine manufacturer has set [A.M.P. "MINOVR" and
"MAXOVR"].
Likewise, the incremental step associated with the "+" and "-" keys of
the Operator Panel to change the programmed spindle speed "S" will
be 10; but this value may be different depending on the setting of axis
machine parameter ["STEPOVR"]
During threading operations, the programmed speed cannot be
overridden and it will be set at 100% of the programmed "S" speed.
