Correcting zero-speed noise in the velocity response
The following graph 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.
