11.12.12.1 Signals for the rigid tapping function
The signals related to interpolation type rigid tapping are basically the
same as for normal rigid tapping. This subsection describes only those
signals that are related to interpolation type rigid tapping. So, see also
Subsection, "Signals for the rigid tapping function".
11.12.12.2 Signals related to gear change
Clutch/gear signals (series spindle) CTH1A,CTH2A<Gn070#3,Gn070#2> : First spindle
CTH1B,CTH2B<Gn074#3,Gn074#2> : Second spindle
CTH1C,CTH2C<Gn204#3,Gn204#2> : Third spindle
CTH1D,CTH2D<Gn266#3,Gn266#2> : Fourth spindle
[Classification] Input signal
[Operation] When a serial spindle is used, these signals post information about the
spindle gear used to the CNC.
The table below indicates the relationships between the signals and
selected gears.
