Signal manipulation <2> above is required to establish a one-to-one correspondence between the
commands and the spindle of the path for which the commands are to be selected in the system
configuration in the above example.
Spindle command selection signals may be handled differently depending on the number of
CNC-controlled paths and the number of controlled spindles (parameter No. 3703 #0, #2).
#1 #0 #2#3#4#5#7 #6
Data type: Bit type, common to all paths
SPR On 2- or 3-path lathe, the spindle with which to perform rigid tapping is:
1: Spindle of the path selected with a spindle command selection signal (SLSPA or SLSPB).
0: Spindle of the path for which a rigid tapping command has been issued.
By setting this parameter bit to 1, you can select the spindle with which to perform rigid tapping
with a similar signal operation as that with an S command.
Note 1) If you set this parameter bit, you must turn the power off and back on for the setting to take
Note 2) If you use this function to perform rigid tapping with the spindle connected to another path,
the parameters listed below will follow the settings of the path to which the spindle is
