2.10.7 Damping
In almost any application it can be useful to damp (suppress) certain oscillations.
The damping selector can be used for this purpose.
The following damping types are available:
- None
Damping feature is disabled.
- Low frequency
When selecting Low frequency, oscillations caused by a poor mechanical transmission
can be reduced. Poor mechanical transmission means backlash in the coupling or
elastic toothbelts, etc. The filter becomes more tolerant to variations in the inertia
which normally can cause the motor to become unstable.
- High frequency
When selecting High frequency, oscillations at higher frequencies will be reduced.
This can typically occur if the filter starts to oscillate at a frequency related to the
sample frequency. Often this can be heard as an audible noise.
- High+Low frequency (only available on MAC400-800)
This is a combination of High and Low frequency settings.
- Low+Low frequency (only available on MAC400-800)
This setting is similar to Low frequency but adds extra tolerance to variations in the
inertia.
