Single-channel all-digital AC servo drives QS7 Series
30
E-gear sub-octave is large (larger than 8);
When motor operational speed is slow, pulse frequency
is lower;
When step jump happens for motor operation, unstable
phenomenon exists.
When it is set as 0, filter cannot work.

P21 Speed gain

Set proportional gain of speed loop regulator;

Bigger in its set value, bigger in gain and rigidity; the
parameter value can be determined upon the specific
servo drive model and loading situation. Generally,
bigger in load inertia, bigger in its set value;

It can be possibly set to be bigger under the situation of
system without vibration.

P22 Speed
integral

Set integral time constant for speed loop regulator;

Bigger in its set value, faster in integral speed, and
stronger in system deviation resistance, i.e. bigger in
rigidity;

However, too big value will produce overshooting.

It can be possibly set to be smaller under the situation of
system without vibration.

(speed)

Setup value refers to the motor acceleration time from 0
to 1000r/min;

Acceleration and deceleration are characterized with the
linear;

It is valid under the modes of speed control and torque
control, and it is invalid under the mode of position
control.
