6.4.6.2 Correcting zero-speed noise in the velocity response
Figure 52 shows a response where there is very little overshoot but a significant amount of
zero-speed noise. This can cause undesirable humming or ringing in the motor.
1. Go to the Fine-tuning window's Velocity
tab.
To reduce the amount of noise, click
Calculate... and decrease the bandwidth
using the slider control. Alternatively, type
a smaller value in the Bandwidth box.
Click OK to close the Bandwidth dialog.
2. Click Go to start the test move. Mint
WorkBench will perform the test move
and display a graph of the result.
