186 Parameters
28.02 Frequency ref ramp
output
Displays the final frequency reference (after selection,
limitation and ramping). See the control chain diagram on
page 383.
This parameter is read-only.
-
-500.00…500.00 Hz Final frequency reference. See par.
46.02
28.11 Ext1 frequency ref1 Selects Ext1 frequency reference source 1.
Two signal sources can be defined by this parameter and
28.12 Ext1 frequency ref2. A mathematical function
(28.13 Ext1 frequency function) applied to the two signals
creates an Ext1 reference (A in the figure below).
A digital source selected by 19.11 Ext1/Ext2 selection can
be used to switch between Ext1 reference and the
corresponding Ext2 reference defined by parameters
28.15 Ext2 frequency ref1, 28.16 Ext2 frequency ref2 and
28.17 Ext2 frequency function (B in the figure below).
Note: The default value depends on the selected macro.
See chapter Control macros on page 27.
