6.4.6 Optimizing the velocity response
It may be desirable to optimize the default autotuned response to better suit your application.
The following sections describe the two main tuning issues and how to correct them.
6.4.6.1 Correcting overshoot
Figure 51 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
W orkBench will perform the test move
and display a graph of the result.
