- Details of the signals
- Signal used to select the spindle motor speed command SINDx
→ The above signal is used to select whether the spindle motor
speed is controlled by the CNC or PMC.
"1" : The spindle motor is controlled according to speed commands
(R01Ix to R12Ix) issued by the PMC.
"0" : The spindle motor is controlled according to speed commands
issued by the CNC. The spindle speed specified with the S
command is output.
- Signals used to input the spindle motor speed command issued
by the PMC R01Ix to R12Ix
→ If the PMC is being used to control the spindle motor speed
command, specify, in binary format, the value obtained using the
following expression.
Value to be specified =
(Spindle motor speed/
Maximum spindle motor speed (parameter No. 4020))×4095
(Spindle motor speed)

- Signal used to select the polarity of the spindle motor speed
command, SSINx
→ The above signal selects whether the output polarity of the
spindle motor speed command is controlled by the CNC or PMC.
"1" : The spindle motor is controlled according to the polarity
command (SGNx) issued by the PMC.
"0" : The CNC controls the polarity. The polarity is determined
by the parameter TCW and CWM bits (No. 3706#7 and #6)
and the M03 or M04 command.
- Signal used to specify the polarity of the spindle motor selected
by the PMC, SGNx
→ If the PMC is used to control the output polarity of the spindle
motor speed command, specify the polarity with this signal.
"1" : The output polarity of the spindle is negative.
"0" : The output polarity of the spindle is positive.
