C-101
You must have the ExecuteNumSpindles task parameter set properly to utilize more
than one spindle.
C.4.123.
S3_RPM
This task parameter defines the feedrate of spindle number three. By default, the units are
revolutions per minute. The G codes listed below will change the units of this parameter.
C.4.124.
S3_SpindleRadius
The S3_SpindleRadius task parameter specifies the spindle radius, which is used along
with the S3_RPM (the S Word) task parameter to compute the actual spindle RPM.
S3_SpindleRadius operates for task 3, use the other parameters for tasks 1, 2 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 (S3_RPM for task 3) 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.4.125.
S4_AnalogMSOInput
This task parameter specifies which analog input channel is used for the analog MSO for
the fourth spindle, as defined by S4_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.4.126.
S4_Index
This task parameter specifies which task axis is used for the fourth spindle axis. This axis
must be a rotary type. The numbers are zero based (i.e., S4_Index = 0 indicates the first
axis). This parameter may not be changed while the spindle is in motion.
C.4.127.
S4_MSO
This task parameter sets the Manual Spindle feedrate Override for Spindle #4 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
S4_AnalogMSOInput task parameter is not -1, the specified analog input determines the
