Fixed Value Change-Over
As a function of the selected configuration, the reference figures 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 connec-
tion of the logic signals with the parameters
Fixed frequency change-over 1
66,
Fixed frequency 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:
