Optimizing the velocity response
It can be desirable to optimize the default autotuned response to better suit your
application. The following sections describe the two main tuning factors and how to
correct them.
Correcting overshoot
The following graph shows a response where the measured velocity overshoots the
demand by a significant amount.
1. Go to the Fine-tuning window's Velocity tab.
To reduce the amount of overshoot, click Calculate... and increase the bandwidth
using the slider control. Alternatively, type a larger value in the Bandwidth box.
Click OK to close the Bandwidth dialog.
2. Click Go to start the test move. Mint WorkBench performs the test move and
displ
ays a graph of the result.
