9. SPINDLE SPEED FUNCTION
439
[Classification] Input signal
[Function] Gear selection signals for 2nd spindle when multi–spindle is equipped
(2–stage). Use GR1 and GR2 <G028#1, #2> for the 1st spindle and up
to 4–stage gears can be used.
GR21 1 : Selects the second-stage gear for the second spindle.
0 : Selects the first-stage gear for the second spindle.
[Classification] Input signal
[Function] Position coder selection signal used for control.
PC2SLC 1 : Uses feedback pulses obtained by the second position coder for
control.
0 : Uses feedback pulses obtained by the first position coder for control.
When the second position coder is not installed, do not switch this signal
and always select the first position coder.
[Classification] Output signal
[Function] These signals inform PMC of whether or not to perform output to the
second spindle in multi–spindle control.
The signals are used as a condition to stop the analog spindle, and are also
used for a PMC ladder sequence that is associated with rigid tapping. (See
Section 9.10.)
[Output condition] ENB2 1 : Outputs a value other than 0 to the second spindle control unit.
0 : Outputs 0 to the second spindle control unit.
1st spindle SIND, SSIN, SGN, <G033#7, #6, #5> (Input)
R12I∼R01I<G033#3 to G032#0> (Input)
2nd spindle SIND2, SSIN2, SGN2, <G035#7, #6, #5> (Input)
R12I2∼R01I2<G035#3 to G034#0> (Input)
[Classification] Input signal
[Function] The spindle motor of each spindle can be controlled by issuing commands
from the PMC. The speed command and polarity (rotation direction) of
a spindle motor can be controlled. Usually, CNC commands are used to
specify a speed and polarity. By using these signals, whether commands
issued from the CNC or PMC are to be used for this control can be
selected. Even when multi–spindle control is not being used, the signals
can be used to control the second spindle.
