250 Parameters
28
28 Frequency reference
chain
Settings for the frequency reference chain.
See the control chain diagrams on pages 594 and 595.
28.01 Frequency ref ramp
input
Displays the used frequency reference before ramping. See
the control chain diagram on page 595.
This parameter is read-only.
-
-500.00 … 500.00
Hz
Frequency reference before ramping. See par.
46.02
28.02 Frequency ref ramp
output
Displays the final frequency reference (after selection,
limitation and ramping). See the control chain diagram on
page 595.
This parameter is read-only.
-
-500.00 … 500.00
Hz
Final frequency reference. See par.
46.02
28.11 Frequency ref1
source
Selects frequency reference source 1.
Two signal sources can be defined by this parameter and
28.12 Frequency ref2 source. A digital source selected by
28.14 Frequency ref1/2 selection can be used to switch
between the two sources, or a mathematical function (28.13
Frequency ref1 function) applied to the two signals to create
the reference.
