Serial spindle clutch/gear signals CTH1A, CTH2A<G227#3, #2>: for 1st spindle
CTH1B, CTH2B<G235#3, #2>: for 2nd spindle
CTH1C, CTH2C<G211#3, #2>: for 3rd spindle
CTH1D, CTH2D<G219#3, #2>: for 4th spindle
[Classification] Input signal
[Operation] When a serial spindle is used, this signal posts information about the
spindle gear being used to the CNC. The signal states and the
corresponding gear selection states are listed below.
CTH1s CTH2s Gear selection
0 0 Stage 1 (high)
0 1 Stage 2 (medium high)
1 0 Stage 3 (medium low)
1 1 Stage 4 (low)
These signals determine which parameter (such as the loop gain) for
each gear is to be used. Do not change these signals in Cs contour
control mode.
Reference position return end signals ZP1<F064#0>, ZP2<F068#0>, ...
[Classification] Output signal
[Function] Indicates that reference position return of a Cs contour control axis has
been completed.
ZPx
x : 1 ... Reference position return end signal for the first axis
2 ... Reference position return end signal for the second axis
3 ... Reference position return end signal for the third axis

::
[Output condition] These signals are set to "1" when manual reference position return or
automatic reference position return command by G28 is complete in Cs
contour control mode and the Cs contour control axis is at the reference
position.
Signals related to manual operation
Feed axis and direction selection signals +J1<G65#0>,
+J2<G69#0>, ..., -J1<G65#1>, -J2<G69#1>, ..., manual handle feed
axis selection signals HS1A to HS1D<G011#0 to #3>, and so forth (see
the related sections in this manual.)
In Cs contour control mode, manual operation other than manual
reference position return can be performed in the same way as for
normal servo axes.
In spindle rotation control mode, do not perform manual operation for
any Cs contour control axis using the PMC ladder.
