9. SPINDLE SPEED FUNCTION
465
When a serial spindle is used, the serial spindle clutch/gear selection
signals (G070#3, #2 for the first spindle, and G074#3, #2 for the second
spindle) must be set in addition to the setting of the gear selection signal
described above.
See the description of the signals related to gear switching, given above.
[Classification] Input signal
[Operation] SWS1 and SWS2 are used to transfer spindle commands when the
multi–spindle control is used. In rigid tapping, the signals can be shared
to select a spindle to be used for rigid tapping. (The signals can be used
for this purpose when bit 7 (SRS) of parameter No. 5200 is set to 0.)
RGTSP2 and RGTSP1 are used to select a spindle used for rigid tapping,
independently of the SWS1 and SWS2 signals, when the multi–spindle
control is being used. (The RGTSP2 and RGTSP1 signals can be used
when bit 7 (SRS) of parameter No. 5200 is set to 1. These signals are
supported only by the T series.)
See the tables below for details of the settings of these signals.
When bit 7 (SRS) of parameter No. 5200 is set to 0, to select a spindle to
be used for rigid tapping, set the signals as indicated below.
