ASDA-A3

5.5 Gain adjustment modes

In addition to the Auto Tuning function, the servo drive also provides the following gain
adjustment modes. You can easily complete tuning by increasing or decreasing the bandwidth
response level (P2.031) or the bandwidth for speed loop response (P2.126). Follow the tuning
procedure in Section 5.1.

5.5.1 Differences between gain adjustment modes

Level adjustment: set the response level with P2.031 to adjust the servo bandwidth. With the
load inertia ratio increased or decreased, the bandwidth corresponding to the response level set
by P2.031 changes as well.
Bandwidth adjustment: set P2.126 to directly determine the servo bandwidth, which fine-tunes
the bandwidth.
