Mode
Set input mode of the position command pulse.
Three input modes can be set through parameters:
0: Pulse＋symbol;
1:CCW pulse/CW pulse;
CCW is counter-clockwise rotation observed from the servo motor
shaft direction, defined as positive direction.
CW is clockwise rotation of observed from the servo motor shaft
direction, defined as negative direction.

Positioning
Completing
Set pulse range for positioning completing under position control
mode.
The parameter provides a basis for judging whether drive unit has
completed the positioning under position control mode. When the
remaining pulse number in the position error meter is less than or
the same with this parameter value, the driver is deemed to
complete the positioning with the positioning completing signal of
COIN ON. Otherwise it will be COIN OFF.
SCMP.Under position control mode, the positioning completing
signal of COIN is output; under other control modes, the speed
completing signal will be output.

Excess
Set inspection range for position excess alarm.
Under the position control mode, position excess alarm will occur in
the servo drive unit when the number on the position error meter
exceeds this parameter value.

Smoothing
Filter
Smoothing filter of the command pulse, acceleration and
deceleration with exponential form, and the value means time
constant.
The filter will not lose input pulse but it may cause delayed
command;
The filter is used in:
Upper controller without deceleration function;
Electronic gear with relatively high frequency division (>10);
Relatively low command frequency;
Motor with leaping-forward and instable steps during operation.
When the position points to 0, the filter will not work.

Stopping
Input
①Set as
0: Valid CCW and CW drive stopping. When CCW drive stopping
switch (FSTP) is ON, CCW drive is allowed; when CCW drive
stopping switch (FSTP) is OFF, CCW torque keeps 0. Likewise, if
CCW and CW drive stopping switches are both OFF, the alarm for
drive stopping input error will occur.
1: Cancel CCW and CW input stopping. No matter what state
CCW and CW drive stopping switches are in, CCW and CW drive
will be allowed. Meanwhile, if CCW and CW drive stopping
switches are both OFF, the alarm for drive stopping input error will
not occur.
