You shall set the Rotations (Pn164 and Pn168) and Max Speed (Pn165 and Pn169) to a proper value. If
the Rotations is set too small or the Max Speed is set too large, it is possible that the maximum speed set
cannot be reached. In this case, it is necessary to increase the Rotations or decrease the Max Speed.
Use the Auto-Tuning Tool as shown in Figure 9-10.
