(c) Connection of servo external signals
There are the following servo external signals.
The A172SENC is assigned a set of input numbers per axis, with the exception
of the tracking enable signal and electromagnetic brake command output. Make
the system settings of the positioning software package to determine the I/O
numbers corresponding to the axis No.s.
