14.4.8 Fixed Value Change-Over
Depending on the selected configuration, the reference values are specified via the
assignment of the
Reference frequency source 475 or Reference percentage source
476. Accordingly, there can be a change between the fixed values by way of linking
the logic signals to the parameters
Fixed frequency change-over 1 66, Fixed fre-
quency change-over 2
67 or the parameters Fixed percent change-over 1 75, Fixed
percent change-over 2
76.
By combining the logic states of the fixed frequency change-over modes 1 and 2,
fixed frequencies 1 through 4 can be selected:
Fixed Frequency Control
