S1_SpindleRadius
The S1_SpindleRadius task parameter specifies the spindle radius, which is used along
with the S1_RPM (the S Word) task parameter to compute the actual spindle RPM.
S1_SpindleRadius operates for task 1, use the other parameters for tasks 2, 3 and 4. (e.g.,
S2_SpindleRadius for task 2). This parameter can equivalently be set with the F
parameter of the G97 command.
If the Spindle Radius is zero, then the units of the S word are assumed to be RPM.
However, if the spindle radius is positive, then the S word (S1_RPM for task 1) is
assumed to be in distance units, and the actual spindle RPM is computed as
RPM = v / (2
π
R)
Where RPM is the result spindle rotation speed, v is the surface speed (the S word value),
and R is the spindle radius provided in the F parameter of the G97 command. Note that
the units of the S word and the Spindle Radius are assumed to be the same.
C.4.115.
S2_AnalogMSOInput
This task parameter specifies which analog input channel is used for the analog MSO for
the second spindle, as defined by S2_Index. Otherwise it is exactly the same as the
AnalogMSOInput task parameter.
You must have the ExecuteNumSpindles task parameter set properly to utilize more
than one spindle.
C.4.116.
S2_Index
This task parameter specifies which task axis is used for the second spindle axis. This axis
must be a rotary type. The numbers are zero based (i.e., S2_Index = 0 indicates the first
axis). This parameter may not be changed while the spindle is in motion.
C.4.117.
S2_MSO
This task parameter sets the Manual Spindle feedrate Override for Spindle #2 on this task.
The value is a ratio varying from 0 to infinity, where 1 represents normal or unaffected
motion. The MSO changes on the MMI600 screens are more restricted. This override
affects only spindle type motion. This does not affect any other type of motion. This value
can not be changed if the MSOLock task mode is active. Also, if the
S2_AnalogMSOInput task parameter is not -1, the specified analog input determines the
MSO value and this parameter becomes read-only and will indicate its value. Likewise,
the MFO slider bar on the Run and Manual (MDI) screens of the MMI600 can only be
used when this parameter is set to –1, other values will enable external control, causing
the slider bar to display the set value.
You must have the ExecuteNumSpindles task parameter set properly to utilize more
than one spindle.
