Signal Connection Interface

Channel #1 in-place comparator function description
The in-place comparator of Channel #1 has four sets of compare input sources for selection,
3
and they are the position comparator values for axes #0, #1, #2, and #3. The output interface
also provides four sets of output interfaces for selection, and they are CMOS3.3V output,
DO output of each axis (24V), axis #3 RS-422 OUT single serial output, and axis #3 RS-422 dual
serial output at the same time (as shown in Figure 3.1.4.3).

Note: in the output selection function interface, you can only select
one channel for output. This means you cannot assign Channel #0
and Channel #1 at the same time for different signal output.
CMOS 3.3V output interface: please refer to Section 3.1.1 for the mechanical DI/O interface
CMP signal description. Please do not share use with Channel #0.
DO output interface of each axis: please refer to Section 3.1.1 for the mechanical DI/O interface
DO signal description.
Axis #3 RS-422 OUT single serial output interface: please refer to Section 3.1.3 for the servo
drive I/O interface pulse output description.
Axis #3 RS-422 dual serial output interface: please refer to Section 3.1.3 for the servo drive I/O
interface pulse output description. Please do not share use with Channel #0.
