The following graphic is a comparison of the normalized filter response, which
is configured for 10 and 100 revolutions. The graphic illustrates how you can
configure a higher number of revolutions to minimize the influence of other
components at near frequencies:
Values Comment
Enable (checked) / Disabled Check the box of the tracking filters that are used.
(not checked)
Tracking filters impart a significant performance demand on the module. To enable tracking filters
that are not necessary adversely affects module performance that is related to non-protection
related measurements and functions.
Select from: Select the TTL signal source to use as the trigger for the selected tracking filter.
• Tach Input 0/Tach Bus 0
The signal source must be a TTL source and must be assigned to the corresponding speed input (0/
• Tach Input 1/Tach Bus 1
1).
0.25...32.0 Enter the order that the selected filter is to track.
• The tracked order is the entered multiple of the running speed of the selected input tacho.
• Integer values (1.0, 2.0...) return both magnitude and phase values, non-integer values return
only magnitude values (phase is set to 0).
