Ramping-down Signals PSD and MSD
There are two ramping-down
(Slow−Down) signals PSD and MSD for one
axis. The relative signal name, pin number and axis number are shown in
the following table.

The signals connection and relative circuit diagram is shown in the following
diagram. Usually, limit switches are used to generate the slow
−down
signals to make motor operating in a slower speed. For more details of the
SD operation, please refer to section 4.3.1.
3.6
In-position Signal INP
The in-position signals INP from the servo motor driver indicate the
deviation error is zero, that is the servo position error is zero. The relative
signal name, pin number and axis number are shown in the following table.
