input
28.1
This parameter is read-only.
- / -Frequency reference before ramping. For scaling, see
parameter 46.2.
-598.00 ... 598.00 Hz
- / real32Displays the final frequency reference (after selection,
limitation and ramping). See the control chain diagram on
page 637.

Final frequency reference. For scaling, see parameter 46.2.
-598.00 ... 598.00 Hz
Zero / uint32Selects frequency reference source 1.
Two signal sources can be defined by this parameter and
28.12 Frequency ref2 source. A digital source selected by
Frequency ref1
source
28.11
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.
