11.3.3 Signals
11.3.3.1 Details on signals
Signals used to select the spindle motor speed command
SIND <G033#7> (for 1st spindle)
SIND2 <G035#7> (for 2nd spindle)
[Classification] Input signal
[Function] This signal specifies that either the CNC or PMC is used to control the
spindle motor speed command.
[Operation] When this signal is 0, the spindle motor speed command is controlled
by the CNC.
When this signal is 1, the spindle motor speed command is controlled
by the PMC.
Signals used to input the spindle motor speed command issued by the PMC
R01I to R12I <G032#0 to G033#3> (for 1st spindle)
R01I2 to R12I2 <G034#0 to G035#3> (for 2nd spindle)
[Classification] Input signal
[Function] When the spindle motor speed command is controlled by the PMC, set
the value obtained from the following expression for this signal in
binary.
Spindle motor speed data =
(Spindle motor speed/Maximum spindle motor speed)×4095
Signals used to select the polarity of the spindle motor speed command
SSIN <G033#6> (for 1st spindle)
SSIN2 <G035#6> (for 2nd spindle)
[Classification] Input signal
[Function] This signal specifies that either the CNC or PMC is used to control the
output polarity of the spindle motor speed command.
[Operation] When this signal is 0, the output polarity of the spindle motor speed
command is controlled by the CNC.
When this signal is 1, the output polarity of the spindle motor speed
command is controlled by the PMC.
Signals used to specify the polarity of the spindle motor selected by the PMC
SGN <G033#5> (for 1st spindle)
SGN2 <G035#5> (for 2nd spindle)
[Classification] Input signal
[Function] This signal sets the output polarity of the spindle motor speed
command.
[Operation] When this signal is 0, the output polarity of spindle is the positive
direction. When this signal is 1, the output polarity of spindle is the
negative direction.
