Sample Continuously:
when the
Start
button is clicked the capture is repeated each time the
trigger condition is met until the
Stop
button is clicked. During continuous sampling the tuning
gains can be changed at any time and will be updated automatically. This allows more dynamic
adjustment of the gains for speeding up the tuning process
NOTE: When adjusting control loop gain values remember that the FF Term (KK) has no
effect when operating in the Position – Pulse & Direction Control Mode.
5.8 Setting the Notch filter
The notch filter is used when there is a specific resonate frequency present in the system and
good performance requires that only the “bad” frequency be removed. Sometimes the resonate
frequency is low enough that it should only be removed using the notch filter. Using the standard
output filter or reducing the gain settings may compromise the system performance too much.
When performing the move profiles as discussed above, a significant resonate frequency may be
experienced visually on the plot window, audibly, or both. Finding this frequency can be a difficult
task and it is often discovered by experimentation. Change the frequency then perform sampling
moves until the resonance is reduced or removed. Keeping the bandwidth wide (maybe equal to
the center frequency) may help find the center frequency. When the center is found, the bandwidth
may be reduced until the resonance starts to return.
