QS2 Series Low Voltage Servo Drive
No. Parameter name
Function
Range
As for debugging, it shall adjust the parameter as
large as possible under the condition of system
operation with no fluctuation and vibration
P17
Position feed
forward
Set the position feed forward coefficient; setting
as 0 does not need to add feed forward; the larger
the setting value is, the larger the feed forward is;
The large the feed forward of the position loop,
the better the high speed response characteristic
of the control system is;

Position
smoothing
coefficient
Set the smooth filtering of the instruction pulse
with an acceleration and deceleration of
exponential form. The value means the
acceleration and deceleration;
0
－
1000
The filtering will not lose pulse but has phenomenon
of instruction delay;
Mainly used in:
➢
The upper computer controller without
acceleration and deceleration function;
➢
The electronic gear frequency is large (larger
than 8);
➢
Slow motor operation and low pulse frequency;
➢
Motor operation with phenomenon of stepping
jump and instability;
➢
The filter takes no effect when setting as 0;
