· Spindle control unit signals for the serial spindle
<G0070 to G0073> (input), <F0045 to F0048> (output)
→ for the first serial spindle
<G0074 to G0077> (input), <F0049 to F0052> (output)
→ for the second serial spindle
These addresses are on the CNC. Actually, however, they are input/output
signals for the spindle control unit for the serial spindle.
For details of the signals belonging to these addresses, refer to the
manuals for the serial spindle:
