An overshoot of about 10% must be obtained. It is important that after the overshoot, an
undershoot does not occur.
Once the optimal value of Pr17 has been established, we must analyze the movement of
the axis. If it moves without vibrations and acoustic noise, the adjustment of the system is
complete. Otherwise, we must repeat the preceding procedures with lower values of Pr16.
In some applications it is possible to reduce acoustic noise by using a higher value of Pr18.
Figure 5 shows that once the optimal adjustment has been achieved, there is also an
oscillation of the current that can produce acoustic noise and mechanical vibration. By raising
the value of Pr18 to 3, the situation is much improved (fig. 6).
