user can begin with 10 degrees that is the default adjustment if a motor with the same rated
current as the converter’s is used.
At this point, let us set the Pr16 to the estimate and turn on the axis with a square wave
reference. (Danger: the reference amplitudes and frequencies must be selected carefully to
prevent problems if the axis is with limited stroke). If we look at the oscilloscope, we can note
that as the Pr17 changes, the response changes too; for decreasing values of Pr17, the system
response shall be as shown in figure 2.
Fig.2
For increasing values of Pr17, the response of the system will be similar to what is shown in
figure 3 below:
