20.2.41 S5-DIGIT COMMAND (SDAI THROUGH S
DA16, DAS, SGSO, GRL, GRH, GRA, GRB, M04S, S1
NV, SFIN) lNPUTS/OUTPUT~
These signals are used to determine the speed of the spindle motor
when the control is in the state of S command 5-Digit Non-Contact
output or S Command 5-Digit Analog output.
GRA and GRB are used to enter the controI state of the gear
range between the spindle and the spindle motor to determine the
spindle motor speed by the spindle speed specified in the part
program.
SINV input inverts the polarity of the anaiog output at the time
of S command 5-Digit Analog output.
While the polarity is inverted, SINV signal is output.
When M03 command is executed, M04S contact is opened.
When M04 command is started. M04S contact is closed.
(1) S5-Digit Command 12-Bit Non-Contact Output
Binary code 12 bits (O to 4095 = spindle motor speed) are
output as follows by the spindle motor speed command and
GR1 through GR4:
—.— ; The output when "GR 1" input is closed. (Set the spindle
motor maximum speed at gear range "GR 1" to parameter
#6271.)
—--; The output when "GR2" input is closed. (Set the spindle
motor maximum speed at gear range "GR2" to parameter
#6272.)
—--- ; The output when "GR3" input is closed. (Set the spindle
motor maximum speed at gear range "GR3" to parameter
#6273.)
—---- ; The output when "GR4" input is closed. (Set the spindle
motor maximum speed at gear range "GR4" to parameter
#6274.)

(2) S5-Digit Command Analog (DAS, SGSO) Outputs
Analog voltages (-10 V to O V to +10 V) are output as follows by
the spindle speed command, GR1 through GR4 inputs, and SINV
