S
In a case of internal reference speed command, this parameter is used to set the
duration of the circular arc segment during S curve decelerating and thus to achieve
the goal of smoothly stopping. The DEC time of S curve is shown in Fig. 6-11.

Pulse input direction
reversing
- 0~1 0 P
By setting this parameter we can reverse the direction of the input pulse. At this time
the actual output speed direction of the servo drive is opposite to the direction indicated
by the pulse input form in Fig. 6-5.
0: Pulse input direction does not change;
1: Pulse input direction is opposite to the original input direction.

P.S.T
This parameter is used to set the zero speed range. When the absolute value of the
speed feedback is in this range, it is considered as zero speed and the output transistor
of the zero speed terminal (ZSO) signal comes into conduction.
