2) Set up the switching level and Hysteresis depending on the switching conditions.
3) Set up the switching delay time.
Set up the time delay for switching from 2nd gain to 1st gain.
Switching conditions have to be established continuously during the switching delay time for the switching
from the 2nd to the 1st.
4) Set up the switching time of position gain.
Switch the position loop gain gradually to avoid any trouble caused by a rapid change to a higher gain, while
the velocity loop gain, time constant of velocity loop integration, velocity detection filter and time constant of
torque filter can be switched instantaneously.
When Pr 1.19 (Position loop gain switching time) is 0,
