range
Unit Title Function/Content
10 0 to 3000
A to C-frame:<63>*
D to F-frame:<32>*
1/s 1st position loop
gain
You can determine the response of the positional control system.
Higher the gain of position loop you set, faster the positioning time you
can obtain. Note that too high setup may cause oscillation.
11 1 to 3500
A to C-frame:<35>*
D to F-frame:<18>*
Hz 1st velocity loop
gain
You can determine the response of the velocity loop.
In order to increase the response of overall servo system by setting high
position loop gain, you need higher setup of this velocity loop gain as well.
However, too high setup may cause oscillation.
<Caution>
When the inertia ratio of SV.Pr20 is set correctly, the setup unit of
SV.Pr11 becomes (Hz).

ms 1st velocity loop
integration time
constant
You can set up the integration time constant of velocity loop.
Smaller the setup, faster you can dog-in deviation at stall to 0.
The integration will be maintained by setting to "999".
The integration effect will be lost by setting to "1000".
